CAPpings - Agriculture - Corrosion Control - Bearings for machinery - The advantages of application-specific bespoke bearings

Asymmetrical double tapered roller bearings for tractor transmissions - This results in an optimum compromise between the two development objectives, i.e. energy efficiency and absorbing high loads. A spacer ensures that play between the two inner rings does not exceed the desired range of tolerance and also prevents corrosion in this critical area.


Bearings for agricultural machinery - The advantages of application-specific bespoke bearings

When the going gets tough:
Severe mechanical strain and abrasive particles in the operating environment: bearings for agricultural machinery have to work in conditions which are far from ideal. Standard products are often unsuitable in these cases because they have a very limited service life. However, bearings are available which have been developed specially for agricultural machinery and mounted implements. Joint development projects by bearing and machinery manufacturers focus on reliable seals and component integration.

Asymmetrical double tapered roller bearings for tractor transmissions
NSK has not only developed customised bearings for mounted farming implements. It has also come up with units for tractor power trains. Here is an example. The company designed a bespoke bearing for a tractor gearbox consisting of a double tapered roller bearing with an asymmetrical cage. One of the two rows of tapered roller bearings was given longer rollers, enabling it to absorb very high loads. A shorter roller design was chosen for the other row to minimise frictional losses and therefore energy wastage.

This results in an optimum compromise between the two development objectives, i.e. energy efficiency and absorbing high loads. A spacer ensures that play between the two inner rings does not exceed the desired range of tolerance and also prevents corrosion in this critical area.

CAPpings - India - Nagapattinam, Tamilnadu - Oil spill on agricultural fields leaves farmers on edge - Ruptures from the old pipeline at intermittent points have been a recurrent feature causing anxiety to the farmers

Agriculture fields in Adiakkamangalam, Keezhvelur (Nagapattinam District, Tamilnadu) are awash with oil that has leaked from the now decommissioned crude oil pipeline of the ONGC-Cauvery Asset. Paddy crop in varying stages of growth stand wilted under the thick slick of crude oil. Ruptures from the old pipeline at intermittent points have been a recurrent feature causing anxiety to the farmers. Corrosion, one of the major causes for oil pipeline leakage, is often overlooked by the oil companies.


Leak from crude oil trunk line of ONGC-Cauvery Asset
At Adiakkamangalam in Keezhvelur, bronzed paddy fields, with burnt grass blades glistening against the scorching sun, catch the eye. Paddy crop in varying stages of growth stand wilted under the thick slick of crude oil.

These fields are awash with oil that has leaked from the now decommissioned crude oil pipeline of the ONGC-Cauvery Asset. Running through vast landscapes of paddy fields, the decade-old pipeline leaked oil that seeped into the dry surface only to resurface as slick following the recent rain.

The crude oil trunk line AKM Narimanam (Adiakkamangalam) was in use till recently. Now, a new line has been commissioned. Ruptures from the old pipeline at intermittent points have been a recurrent feature causing anxiety to the farmers. In August 2011, a similar rupture along the pipeline near river Devanadhi ruined Samba paddy fields. However, the damage was contained by the river, which washed away the oil slicks into the sea. But now, the crude oil spill has begun flowing along the Kohur irrigation channel, which irrigates over 300 acres, across the villages of Manjavaadi, Anaimangalam, Kohur, Thenkarai and Vadakarai.

It is telling on the already weak prospects of the samba crop. Several acres of paddy fields irrigated by the oil slick-laden water from the channel have been ruined.

CAPpings - India - Dapodi residents complain of contaminated water supply in Pune - Water pipelines are very old

PUNE: Residents of some areas in Dapodi have been facing problems of water logging and contaminated water supply for the last four days.

Water pipelines in the area are very old due to which drainage water gets mixed with drinking water pipelines.

PUNE: Residents of some areas in Dapodi have been facing problems of water logging and contaminated water supply for the last four days. Areas that have been affected include SMS colony, Pawar Vasti and Phulenagar. The problem has been caused following the heavy rains.

Local NCP corporator Rama Ovhal said, "Due to the heavy rains, the drainage lines in the civic ward (No 61, Hutatma Bhagat Singh school, Dapodi) have choked up in some areas. Around 300 families have been affected," she said.

Ovhal said the water pipelines in the area are very old due to which drainage water gets mixed with drinking water pipelines. Samples of contaminated water were shown to civic officials of the Kasarwadi-Dapodi zonal office, she said. Rajendra Pathak, a resident of Kate chawl, said, "Local residents are getting contaminated water for the past five to six days. The water supplied through the water pipeline to us has a foul smell which shows that it is contaminated with drainage water."

CAPpings - Dental Implants - Titanium implants may carry risk of corrosion

Titanium medical implants used in dental prostheses and bone-anchored hearing aids may be less robust than commonly believed. Researchers have found evidence to suggest that in environments where there is no significant wear process, microscopic particles of titanium can be found in the surrounding tissue, which may have a negative impact on the devices, as this can potentially be pro-inflammatory.

Globally, more than 1000 tonnes of titanium (Ti) is implanted into patients in the form of biomedical devices on an annual basis. Ti is perceived to be ‘biocompatible’ owing to the presence of a robust passive oxide film (approx. 4 nm thick) at the metal surface. However, surface deterioration can lead to the release of Ti ions, and particles can arise as the result of wear and/or corrosion processes. This surface deterioration can result in peri-implant inflammation, leading to the premature loss of the implanted device or the requirement for surgical revision.

Soft tissues surrounding commercially pure cranial anchorage devices (bone-anchored hearing aid) were investigated using synchrotron X-ray micro-fluorescence spectroscopy and X-ray absorption near edge structure. Here, we present the first experimental evidence that minimal load-bearing Ti implants, which are not subjected to macroscopic wear processes, can release Ti debris into the surrounding soft tissue. As such debris has been shown to be pro-inflammatory, we propose that such distributions of Ti are likely to effect to the service life of the device.

The study “Do ‘passive’ medical titanium surfaces deteriorate in service in the absence of wear?” was published online on 25 July in the Journal of the Royal Society Interface

CAPpings - Home Remedy for Corrosion - Affection with Family Favorites prompts maintenance of old cookware - How to clean and season old and rusty Cast Iron pan?

Affection with Family Favorites prompts maintenance of old cookware - A Home Remedy for cleaning and seasoning old and rusty Cast Iron Pan.




We all love our mothers' old pots and pans, simply because they have been great companions to all the delicious and nutritious meals moms cook for us all these years. There must be at least a frying pan in the kitchen that has been there since as long as we can remember, and it usually is the family's favorite one.

The only problem is, any cast iron will rust eventually, even if it takes a few decades. Removing surface rust from the family's favorite cast iron skillet could be agonizing, if you don't know the correct way of doing it.

Article Source: http://home24malaysia.blogspot.com/2012/08/tuesday-tips-how-to-clean-rusty-cast.html
Publication Date: 14 August 2012



What You Need

Materials
The end chunk of a potato (enough to be able to hold firmly)
Course salt
A rusty cast iron skillet
A little vegetable oil (canola or olive will do)

Equipment
Gloves (optional, but recommended)

Instructions
1. Place your rusty skillet in the sink and sprinkle a couple tablespoons of salt into it.

2. Take your chunk of potato and start scrubbing. The moisture from the potato will be enough to help the salt dig in to the rust.
3. The salt will get dirty very quickly. You may choose to rinse out the pan to survey your progress. If there is still rust, add more salt and repeat Step 2.
4. Continue to the sides, edges, bottom and handle of your pan.
5. Rinse thoroughly and pat dry.
6. Place pan on stove burner, this will help dry any remaining moisture.
7. Once dry, put a small amount of vegetable oil in the pan and rub it in with a paper towel.
8. Keep pan over low heat for at least 30 minutes.
9. Let skillet cool. Make sure to wipe off any excess oil before storing your skillet. If you leave extra oil in the pan it can turn rancid.
10. Every time you use your pan, after you've cleaned it put the pan on a low burner and repeat the oil and paper towel step. It's best to store your pan in the oven, but it worked much better when stoves had pilot lights that stayed on (thus keeping ambient moisture away from your pans).

Your seasoned and loved cast-iron skillet will now looks brand new!

CAPpings - India - Sewage water leaks into drinking water in Bhubaneswar, Orissa

Sewage water leaks into drinking water in Bhubaneswar, Orissa. Following complaints of skin and stomach ailments in the area, the public health department has stopped supplying pipe water and is providing water through tankers.



BHUBANESWAR: For the last seven days residents of Ashok Nagar have been getting contaminated water. Residents of the area alleged sewage water has been leaking into piped water. Following complaints of skin and stomach ailments in the area, the public health department has stopped supplying pipe water and is providing water through tankers.

"A few days ago I detected a stench in the pipe water and later we became certain it was the smell of sewage," said Harman Das, a resident of Ashok Nagar. By the time he realized this, however, his wife had developed stomach infections, he said. "My neighbours also had the same complaint. Many of them had started suffering from skin irritation, and we immediately lodged a complaint with the public health and engineering division-I (PHED)," he added.

CAPpings - India - Transportation -The All-Composite Corrosion Resistant Bus Comes To India

A composite bus is lighter, consumes less fuel and resists corrosion and damage better than steel-bodied buses. While the initial cost is higher, its maintenance is cheaper making the total cost of ownership attractive.


The All-Composite Bus Comes To India


A technology that can make passenger buses lighter and more efficient comes to India in its search for mainstream acceptance. The idea of a composite bus is as simple as it is compelling. In the manufacture of a conventional bus, a chassis or the basic framework to hold all the parts is made with steel. Then, a body is built on it using more steel. A lot of welding goes into binding everything together. In the end, we have a very heavy product that has thousands of independent components.

On the other hand, a composite bus body is just two moulds fused together. Engines, seats and other stuff are fitted into this shell. And voila, the bus is ready. But the irony is that the all-composite bus is not in the mainstream anywhere in the world. In fact, it has seen wide adoption only in the US state of California. From European nations to Korea, bus operators are warming up to this technology but are yet to make large-scale commitments. Even in the US, success has not been easy. The pioneer, North American Bus Industries (NABI), had to wait for nearly a decade before it got accepted in the market.

India is on the threshold of becoming one of the hottest markets for buses in the world. Economic growth has led to a whopping increase in public transport needs in its burgeoning cities. For long, the demand was for only about 30,000 buses a year but the graph has now taken a steep turn upwards. In 2010, bus sales in India reached a record 38,000. Industry experts expect the number to reach as high as 60,000 by 2015.

Much of this demand will arise for better quality, high-tech and luxury buses. Till recently, the market was dominated by rickety, noisy buses that broke bones. In many cities, commuting was a nightmare because too many people were crammed into too few buses that were poorly maintained. Cash-strapped state-run bus corporations bought the cheapest models available and never invested in modern technology, emission reduction or passenger comfort.

The work to replace the pipeline will be undertaken under 24X7 water supply project. Until that work is completed, the problem of contaminated water supply cannot be solved.


Nagpur to get contaminated water for 5 more years

NAGPUR: The sad state of affairs at Nagpur Municipal Corporation (NMC) came to fore on Monday when the civic body warned it cannot guarantee water free of contamination for the next five years at least. Executive engineer of NMC's water works department Shashikant Hastak made this statement in the house during the general body meeting on Monday.

The entire water network spread over 550km in Nagpur is old and requires to be replaced. The work to replace the pipeline will be undertaken under 24X7 water supply project. Until that work is completed, the problem of contaminated water supply cannot be solved.

Making this scary statement, which shocked the entire house, Hastak, who is also executive director of Nagpur Environmental Services Limited (NESL), a special purpose vehicle for monitoring 24X7 water supply project, said the level of water contamination may be brought down but there is no hope for complete resolution of the problem for five years.

CAPpings - India - Corrosion of old drinking water pipelines is posing the threat of contamination in Chennai - 650km out of 2000km pipelines replaced with new ductile iron and mild steel pipes

Corrosion of drinking water pipelines is posing the threat of contamination in Chennai - Finally, waking up to the threat of water contamination in the city, Metrowater has started replacing pipelines. More than 2,300km of pipelines that criss-cross the city were laid in the mid 1960s. Now, many of them may have corroded, leading to seepage of sewage and other impurities into the pipes.

650km water pipes changed, twice as much still to go.

CHENNAI: Finally, waking up to the threat of water contamination in the city, Metrowater has started replacing pipelines. More than 2,300km of pipelines that criss-cross the city were laid in the mid 1960s. Now, many of them may have corroded, leading to seepage of sewage and other impurities into the pipes.

Public health experts say this is a crucial step in preventing waterborne diseases. Metrowater has got Rs60 crore under the Jawaharlal Nehru National Urban Renewal Mission (JNNURM) to replace all the drinking and sewerage water pipelines within the older city limit.
The department had identified'more than 2,000km of pipelines along 15,000 roads. About 650km of pipelines running under areas such as Guindy, Virugambakkam, T Nagar, Saidapet, Choolai, Royapuram, KK Nagar and Villivakkam have been replaced with new ductile iron and mild steel pipes. "Most of the pipelines in the old areas were of cast iron, which rust over time. We will replace the old pipes by December-end," said a Metrowater official.

The organization has been facing problems clearing sewerage and supplying drinking water. The city has around five lakh water connections. Leaky pipelines are the main cause of water contamination. "Only if there are leaks do sewage water seep in. The liquid also overflows on the road only when the links are weak, and not able to withstand pressure," said former assistant city health officer Dr Damodaran Reddy.

Health officers say water contamination happens frequently during monsoon, which is why Metrowater increases the chlorine content in water by five times. Experts also feel that having a common enclosures for garbage collection in neighbourhoods could have also aggravated the problem.

CAPpings - USA - Corrosion halts Global Production of Stryker Orthopedic metal-on-metal hip implants

Corrosion halts Global Production of Stryker Orthopedic devices. Fretting and/or corrosion of metal-on-metal hip implants could cause pain, swelling and tissue damage




Orthopedic devices maker Stryker recalls a pair of metal-on-metal hip implants and halts global production after discovering potential for "fretting and/or corrosion" that could cause pain, swelling and tissue damage.

Orthopedic devices giant Stryker (NYSE:SYK) announced recall of a pair of hip implants over concerns that the devices may be prone to "fretting and/or corrosion at or about the modular-neck junction," which may lead to pain, swelling and adverse reactions in surrounding tissue.

The recall affects the company's Rejuvenate Modular and ABG II modular-neck hip stems, and Stryker decided to terminate global production of the devices after discovering a potential trend in post-market surveillance data.

"While modular-neck stems provide surgeons with an option to correct certain aspects of a patient's anatomy and hip biomechanics, given the potential risks associated with fretting and corrosion at the modular neck junction, Stryker Orthopaedics decided to take this voluntary action," hip reconstruction vice president and general manager Stuart Simpson said in prepared remarks.

CAPpings - India - Poison potion in pipe leak pang in Bihar - Corrosion leads to contamination of drinking water - Hundreds of people have started suffering from diarrhoea

Poison potion in pipe leak pang in Bihar. Leaks in supply pipelines have left residents of a major portion of the town high and dry this monsoon, compelling them to quench their thirst with water filled with mud and dirt. Hundreds of people have started suffering from diarrhoea with Jaiprakash Narayan Hospital alone receiving 33 patients from Iqbal Nagar near Ramshila hills in the past two days.

Leaks in supply pipelines have left residents of a major portion of the town high and dry this monsoon, compelling them to quench their thirst with water filled with mud and dirt. The result is predictable; hundreds have started suffering from diarrhoea with Jaiprakash Narayan Hospital alone receiving 33 patients from Iqbal Nagar near Ramshila hills in the past two days. “Eighteen of them were admitted today,” hospital deputy superintendent S.Z. Ahsan told The Telegraph.

“They are suffering from diarrhoea because of drinking contaminated water,” he said, adding that the residents were prone to suffer from typhoid, jaundice and even acute encephalitis syndrome if they drink such water. Not that the residents have an option to get pure drinking water. Sources said water supplied through pipelines has become polluted with rainwater seeping into them through the leakages.

A laboratory test of water sample, collected from Gurudwara Road, revealed that it had turbidity much higher than a human system can tolerate. “The test conducted at the laboratory of the public health and engineering department showed that the turbidity of water is 10 times higher than the desired level and five times higher than the permissible limit. The laboratory has declared the water unfit for consumption,” a source said.

CAPpings - India - Corrosion of Drinking water pipelines laid inside sewage lines leads to contamination of water supplied to the public in Nagpur

Nagpur: Most water pipelines have been laid inside sewage lines and storm water drains. The pipelines have rusted and developed leaks in many places. The sewage and drain water enters the pipeline when there is no water supply, thus contaminating the drinking water.



NMC corporators tell of water pipes laid in sewage lines, storm drains

NAGPUR: In a shocking revelation, it has come to light that drinking water pipelines have been laid inside sewage lines and also storm water drains at some places in the city. This is said to be the main reason for the contaminated water supply in parts of Central and North Nagpur.

"Citizens from Santosh Nagar, Mehboobpura, Pandey ki Basti, Yogi Arvind Nagar, Sarwarabad, Hamid Nagar, Sangham Nagar and Yashodhara Nagar have been worst affected. Most water pipelines in these areas have been laid inside sewage lines and storm water drains. The pipelines have rusted and developed leaks in many places. The sewage and drain water enters the pipeline when there is no water supply, thus contaminating the drinking water. The first water received when supply resumes is yellowish. Some areas also get blackish water when supply resumes," he said.

Major leakages in the main pipeline near Thuvariman and Melakkal leading to drinking water shortage in Madurai. Every morning, the complaints on water shortage by residents have become a big problem


Council meet awash with water scarcity issue
Commissioner of Madurai Corporation clarified that major leakages in the main pipeline near Thuvariman and Melakkal was the reason behind the short supply.

Ruling party councillors charged the Corporation officials of creating an artificial drinking water shortage in the city at the council meeting here on Friday. However, Commissioner clarified that major leakages in the main pipeline near Thuvariman and Melakkal was the reason behind the short supply. The leaks would be plugged on July 3 and 4, he said.

Zonal chairperson said that he had been complaining of short supply of water in his zone for the past three months but officials showed no sign of attending to it. “Every morning, the complaints on water shortage by residents have become a big problem,” he said.

Mayor pointed out that there were problems in bringing water from Pannaipatti water treatment plant owing to a leakage. Ruling party member complained that poor quality of work in execution of the second drinking water pipeline for the city during the earlier rule was the reason for the frequent disruption of water supply.

A recent survey by the Municipal Corporation of Delhi created ripples in the city with revelations that a large portion of Delhi’s water is not fit for drinking. At least 81 out of 116 water samples collected by MCD contain physical impurities. The reason for such a situation is the use of old and corroded water pipes.


MCD report pins DJB for not ensuring clean supply

A recent survey by the Municipal Corporation of Delhi created ripples in the city with revelations that a large portion of Delhi’s water is not fit for drinking. At least 81 out of 116 water samples collected by MCD contain physical impurities.

The reason for such a situation is the use of old and corroded water pipes. Some public water pipes also run parallel to sewer lines in the Capital. So whenever there is a leakage or a pipe breaks due to corrosion, sewer water enters into drinking water pipes. “We gave a list of 1,000 such pipelines that needed to be repaired or replaced. But DJB took care of only 50 pipes in the last one year,” said Dr Monga.

CAPpings - India - A constructor's perspective on Corrosion of RCC structures in Coastal Areas


Corrosion of reinforcing steel is one of the most important causes of deterioration of concrete structures in coastal environment



Steel and other ferrous metal along the coastline are susceptible to corrosion, which is mainly initiated by chloride ions present in the sea salts. It is further sustained by the oxygen present in the atmosphere, which diffuses through the moisture film to the surface of the metal.

Corrosion of reinforcing steel is one of the most important causes of deterioration of concrete structures in coastal environment. High permeability concrete, poor design detailing and construction defects such as inadequate depth of cover allow the ingress of salt and moisture into the concrete. High concentration of salt and moisture result in accelerated corrosion of reinforcing steel thereby significantly deteriorating the concrete structure.

Concrete structures in coastal areas can be divided into two categories based on their exposure: direct and indirect. Direct exposure includes structures that are fully or partially submerged and indirect exposure includes structures that do not come into direct contact with seawater. Buildings along the coastline are examples of indirect category of exposure.

Corrosion is commonly associated with deposition of sea salt in presence of moisture on steel and light metals. Chloride is the most significant corrosive species in the salt particles. Corrosion is influenced by the amount of salt on the metal surface and related to speed and direction of wind, distance of structure from the shore, elevation of the structures, degree of sheltering and frequency and amount of rain washing. Other factors that influence corrosion include time of wetness, relative humidity, metal surface temperature etc. Normal steel has poor resistance in coastal atmosphere and hence requires protection for durability.

When steel reinforcement corrodes, the corrosion product occupies more than three times the volume of the original steel, exerting great disruptive tensile stress on the surrounding concrete, leading to further cracking, more weather access and further corrosion. In mild cases, rust staining occurs whereas in more serious cases severe spalling of concrete may occur and ultimately the concrete members may fail completely.

CAPpings - India - Musical Instruments - Are Guitars built in areas at Low Humidity suitable for High Humid Places? - Corrosion annoys Guitarists.



Corrosion of Guitar Strings due to high humidity disturbs a Guitarist from India



Guitars suited for high humidity?

I live in a place (in India) that is very humid. The monthly average afternoon relative humidity hovers between 65% and 80% across the twelve months. The monthly average morning relative humidity is anywhere between 85% and 92%. I was trying to buy a guitar (built in a controlled workshop relative humidity level of 45%) from a luthier in Sweden but abandoned the idea because he too agreed with me that the humidity here could be a problem. Is getting a guitar built in a workshop set at a high relative humidity the only way to go? I know it's highly improbable but I will ask this anyway at the risk of sounding dumb! Would I be able to find a good luthier based in a place with similar humidity conditions as I described above who builds under the normal climatic conditions of that place, or who build guitars specifically for humid places? My budget is 4500 USD and I prefer a Spruce/Maple combination (just in case it helps respondents).

CAPpings - Water Damage, a big concern for Electronic Gadget Users: Corrosion leads to malfunction of devices like iPhone, iPod when exposed to Water or other liquids

If an electronic device like iPhone or iPod is exposed to water or other liquids, corrosion—an irreversible deterioration or degradation of materials—may result. This may cause the device to malfunction. There is no warranty for liquid damage.


If an iPhone or iPod has been damaged by liquid (for example, coffee or a soft drink), the service for such liquid damage is not covered by the Apple one (1) year limited warranty or an AppleCare Protection Plan (APP). iPhone models and iPod models that were built after 2006 have built-in Liquid Contact Indicators that will show whether the device has been in contact with water or a liquid containing water.

If a device is exposed to water or other liquids, corrosion—an irreversible deterioration or degradation of materials—may result. This may cause the device to malfunction. If a device has been or is suspected to have been exposed to water or other liquids, inspect the following areas for evidence of corrosion: the dock connector, the headset/headphone jack, the dock screws, the speaker or microphone mesh, and any exposed metal parts. 

iPhone and iPod products are equipped with Liquid Contact Indicators in the bottom of the headphone jack. iPhone 3G, iPhone 3GS, and later models also have an indicator on the bottom of the dock-connector housing. These indicators will be activated when they come in direct contact with water or a liquid containing water. They are designed not to be triggered by humidity and temperature changes that are within the product's environmental requirements described by Apple.

At the base of the headphone jack, you should see what is normally a white or silver-colored dot. The dot will become full or half red or pink when the dot has come in contact with water or a liquid containing water.

CAPpings - Performance Contracts: Shaking Up The Municipal Water Market? - Does this approach open doors for corrosion control leading to water conservation and supply of healthy water?

Performance contracts promise to shake up the municipal water market — and to open the drinking water and wastewater sectors to new heights of innovation, efficiency, and funding opportunities.

This will open the doors for efficient corrosion control to conserve water and avoid contamination.


Performance contracts promise to shake up the municipal water market — and to open the drinking water and wastewater sectors to new heights of innovation, efficiency, and funding opportunities.  As Steve Hoffman  wrote in Planet Water: Investing in the World’s Most Valuable Resource, “the water industry is being  rationalized from a delivery-based approach to a solution-based system.”
Instead of manufacturers delivering equipment to an installation and driving away, or consulting engineers wrapping up most of their work once a new facility is online, performance contracts put the risk — and the reward — of performance on the supplier side.  Contracted operators deliver water for a negotiated sum, or earn their pay as incentives for achieving agreed-upon goals — for instance, cost savings over previous systems. Utilities reduce their up-front expenditures, their risk and, often, the need to go to voters for bond measures.
To investors, that’s like a long, cool drink of water on a hot day.  A contract guaranteeing a certain level of performance, seasoned with the security of working with municipalities on the most inelastic of commodities — it’s a solid bet.  Coupled with growing interest in non-traditional financing tools like public-private partnerships and private activity bonds, performance contracts offer increasingly attractive opportunities for investors, which in turn open up great opportunities for municipalities.

To equipment manufacturers, performance contracts are a call to the drawing board, a chance to grow their business through innovation and product improvement rather than face the gauntlet formed when engineers only specify predictable, plain-vanilla, previously-approved technologies in traditional installations.

To consulting engineers, it’s a huge disruption.  Replacing the old design-bid-build model with design-build-operate or even design-build-own-operate arrangements changes the business model for many consulting firms.  In the new system, the money comes from efficiencies in operating expenses (OPEX) rather than a piece of the capital expenses (CAPEX).  The paycheck is spread over long contracts – no more bid ‘em, build ‘em and move on.

On the flip side, the shift creates opportunities for consulting engineers to focus their training and expertise on pilot testing, creating OPEX efficiencies and overseeing construction.  A lesson from the electric and gas utilities is that scalability — turning successful pilot plants into commercial realities that deliver the same benefits — is a huge challenge, notes Linda Jackman, vice president of industry strategy for Oracle Utilities.  That makes understanding pilot design and scale a key competency for the new generation of successful consulting engineers.

Consulting engineers’ expertise must bridge into the burgeoning world of data, which means tomorrow’s consulting engineers (and many of today’s) need to serve up their hydraulics with a data analysis chaser.

CAPpings - Jewellery - Why does Gold (14 carat) change color or discolor skin? Is it a corrosion concern for jewelry users at the time of soaring Gold price?

Gold itself does not corrode, but its primary alloys of silver or copper will do so—forming very dark chemical compounds—under moist or wet conditions.

If you sweat, fatty acids released by your body can cause corrosion of 14 Karat gold.


Pure gold itself does not corrode, but its primary alloys with copper or silver will do so forming very dark chemical compounds under moist or wet conditions. If you perspire, fatty acids released by your body can cause corrosion of 14 Karat gold. This problem can be worse in coastal and humid areas where sea salt in the air combines with perspiration and discolors skin. The chlorine, which is routinely added to the swimming pools and spas, is one of the worst enemies of gold. Corrosion can weaken gold's structure, eventually leading to breakage.

Article Source: http://www.goldmasters-sa.com/jewelryfacts.htm

Chemicals such as chlorides and sulfides contained in perspiration may react with metals  contained in the gold alloy, causing a black mark on your skin. Eating lots of tomatoes or drinking many cups of coffee may cause problems for some people. Your body chemistry may change from time to time.  A ring which previously caused no problem could suddenly start to smudge your finger. Exposure to chemicals outside the body can also have the same effect. Salt reacts with the alloys in yellow gold to cause corrosion. Eating that box of salted popcorn in the movie may cause your jewelry to darken your skin.

CAPpings - India - Beauty and Fashion - Corrosion (rust) affects beauty of hair

People who have natural red hair look beautiful, but when you inherit the same because of iron and rust deposits, your hair looks ugly. 
Iron and rust deposits on hair are a common phenomenon




It may be caused by well water, excessive hard water or water which comes from old rusty pipes that get iron films on them due to their years of corrosion.

How to Remove Iron and Rust from Hair
-There are popular rust removal shampoos and conditioner in the market, which reduce the orange tint. The usage varies from product to product and one should make sure to read the instructions, before applying the product.
-Rinse your hair with a mixture of vinegar, added with some cream of tartar. Leave it for about 10 minutes and rinse with cool water.
-Another option is to use lemon juice. Apply lemon juice on your hair, leave for 10-15 minutes and rinse thoroughly.
-Mix baking soda with your shampoo. Use this to wash the hair and then rinse with water. Make sure to use a conditioner later on.

Preventive Measures
The remedies provided in the above lines would lessen the redness primarily. However, the problem will tend to continue, unless and until proper preventive measures are taken. Some of them have been mentioned below.
-Get a water purifier for your home or change the water pipes
-Do not use excessive chemicals and avoid experimenting a lot with the use of machines on your hair.
-Do not let your hair remain wet for a long time, as the reaction between iron and water cause rust to occur

CAPpings - India - Improper coating selected for internal corrosion protection of drinking water pipe and tanks puts public health at risk - Toxins in Mumbai's drinking water could hit 7 lakh

Improper coating selected for internal corrosion protection of potable water pipe and tanks puts public health at risk.

Toxins in Mumbai's drinking water could hit 7 lakh people


CAP-cycle Rider: Manish Jhurani

MUMBAI: The BMC may be risking the health of around seven lakh people living in the Sion-Sewri belt following the reopening of the Raoli water reservoir, whose two tanks have been coated with a polyurethane to protect their insides from rusting. A written complaint to the civic vigilance department says that the chemical coating has been done improperly and could lead to toxins being released into potable water. Health experts have said that MDI, a chemical in the coating, could cause respiratory ailments, skin rashes and kidney stones or even increase a person's risk of getting cancer.

A January 13, 2010 letter from the ICT to the BMC states that a visual exam of two samples submitted by the civic body indicates the polyurethane coating in the tanks is "defective'' and has evidence of "unevenness and roughness". Furthermore, the ICT says there is "improper curing of coating material". This means that the two elements that combine to form polyurethane–resin and MDI– have not properly bonded to create the non-toxic film that would allay rusting.

Civic officials and scientists said that the MDI could enter the water and render it toxic. The ICT report says the "material may not provide a protective barrier'' to the steel. "As there is also evidence of coating failure, the material may leach out and affect safety of potable water, even if it complies with test requirements," says ICT's letter to the BMC.

Inspite of this, similar products are used for other pipelines. Moreover, the work going on the eastern express highway for pipeline is going on since past 6 years. all pipes are lined with cement. think about the field joints, condition of cement when exposed for so long, damages/hairline cracks occuring while transportation. These issues can be solved very easily resolved if corruption reduces

India - Water Contamination - Earthworms had fallen out of drinking water taps in around 50 homes in Patna. Civic officials blamed the decades-old pipeline for the problem of unhygienic water supply

Earthworms had fallen out of drinking water taps in around 50 homes in Patna.

Civic officials blamed the decades-old pipeline for the problem of unhygienic water supply


Patna Municipal Corporation (PMC) authorities on Monday asked the technicians concerned to repair the water supply pipelines to the Mangal Talab area in Patna City after The Telegraph reported in its June 18, 2012 edition how worms gushed out of taps at some of the homes in the locality on Sunday.

“I read the report in The Telegraph. We have ordered the officials concerned to repair the water supply pipelines in the area by tomorrow (Tuesday),” said PMC chief engineer Ramsawarath Singh.

He added: “The pipeline in the area was laid a long time back. It is around 7-8-ft beneath the ground. Most of the times, it is difficult to find out where the exact leakage has occurred. But this time it seems that the leak has been caused during repair works.”

Sharma, along with German scientist Dr Hasko Nesemann attached with the Central University of Bihar, also prepared an investigative report on the organism claiming: “On 17th June 2012, an already known large aquatic worm (18cm fully extended) species with the scientific name Glyphidrilus gangeticus Gates, 1958, has been recorded for the first time from tap water in Patna City area near Mangal Talab

CAPpings - India - Leakage of acid water that has affected agriculture fields and aquatic life in Orissa - Change in material for better corrosion resistance

Leakage of acid water that has affected agriculture fields and aquatic life in Orissa.

Change in material from Iron to Fibre didn't solve the public problem: the installation of fibre pipeline was not done properly which resulted in the crack


PARADIP: A day after the fibre gypsum pipeline of Paradeep Phosphates Ltd (PPL) leaked on Monday, fishermen of adjacent areas alleged that dead fish had been sighted at various water bodies.

Officials of the State Pollution Control Board (SPCB) along with local Fisheries Department officials visited the spot on Tuesday morning where the pipe had leaked. The SPCB officials collected water samples from the nearby water bodies for examination. The district administration, on the other hand, has deployed a team to conduct an inquiry into the leakage of acid water from the pipeline and ascertain loss of marine life.

Following government intervention, the plant management changed the iron� pipeline to fibre pipeline. “However, the installation of fibre pipeline was not done properly which resulted in the crack,”

CAPpings - India - At least 250 million litres of water a day, which can cater to two lakh households, is lost every day in Bangalore due to old, rusty pipes and poor distribution

At least 250 million litres of water a day, which can cater to two lakh households, is lost every day in Bangalore due to old, rusty pipes and poor distribution.

37 per cent of water literally goes down the drain


Bangalore thirsts for better water supply

Spiralling population and the Bangalore Water Supply and Sewerage Board's (BWSSB) failure to augment supply has ensured that the city is perpetually in the grip of a water crisis. If the depleting water level in the T.G. Halli reservoir and the delay in the Cauvery Stage IV Phase II scheme are bothering residents and officials, a deeper malaise ensures that the water shortage is perennial: at least 37 per cent of water literally goes down the drain due to old, rusty pipes and poor distribution. Added to this are illegal connections.

The drinking water pipeline network of 7,500 km carries water to 6.1 lakh households. Inequitable supply is the order of the day. While some areas get an enviable supply of water, others have just air in their taps. Engineer-in-Chief Venkataraju admitted that at least 37 per cent of the 900 mld goes waste due to old, rusty pipes and poor distribution. Citing various reasons for the irrational distribution which accentuates the shortfall, he said the city falls short of 883 mld.

While 15 per cent is wasted because of pipe and joint leaks and corroded house service connections, the rest is unaccounted for due to seepage in ground-level reservoirs and malfunctioning meters. “If we can reduce the wastage, we will save at least 250 mld. This can cater to nearly two lakh extra households,” he said.

CAPpings - India - 1000 pipe-bursts reported each year leading the way for Corrosion induced water contamination in Mumbai

1000 pipe-bursts reported each year leading the way for Corrosion induced water contamination in Mumbai




BMC has a tough time maintaining the 4,000-km pipeline network which has been constantly under pressure from a burgeoning population and careless infrastructural work carried out by government agencies. The civic budget has made provisions to increase water sample collection to tackle the situation. The laboratory at G-North ward is being upgraded to test 1,000 samples per day and the laboratory at the Bhandup complex 250 per day.

Mumbai has a network of corroding pipelines and when they burst, waste from sewage lines enters the water supply, leading to contamination. Roughly 1,000 pipe-bursts are reported (each year)," a civic official said.

CAPpings - USA - Infrastructure Upgrade - Water pipelines replacement calls for hike in residential water bill

Aged water pipelines are replaced due to leakage, corrosion and longterm sediment accretion

Pipeline replacement calls for hike in customer (residential) water bill



Illinois American Water Co. is investing $1.2 million to replace water main piping in parts of Belleville, East St. Louis, Granite City and Venice. The original piping is rife with leaks, corrosion and longterm sediment accretion, according Grant Evitts, senior operations manager for the Interurban District. "The water mains we are replacing with this project were installed over 50 years ago," Evitts said. "Upgrading the infrastructure is essential to ensuring quality water service.

According to utility company spokeswoman Karen Cotton, the funding for this project will be provided by revenue from customer water rates. These rates, which aren’t subsidized with taxes or fees, are based on the true cost of providing water service, including water treatment, distribution, customer service, meter reading and infrastructure investments that need to be made to ensure water quality and upgrading of the water main systems.

There will be 1,509 feet of 2-inch galvanized piping replaced with 8-inch ductile iron on Coral Drive from Carlyle Avenue to Gardenia and from Shady Lane to Holly Drive. Later this year, 750 feet of water main will be replaced on South Pennsylvania Avenue in Belleville.

On Oct. 27, Illinois American filed a request with the Illinois Commerce Commission for a rate increase of $7.06 a month to be added to the existing $43.65 per month average residential bill. The review process is pending.

CAPpings - India - Corrosion of water pipeline, a weird excuse for draining water as per central guideline to avoid burst

Corrosion of water pipeline, a weird excuse for draining water as per central guideline to avoid burst.

Most supply pipes in Ranchi are as old as 44 years. Sealing leaks is a difficult proposition in Ranchi

Near Khelgaon Chowk, the damaged drinking water supply pipe from Rukka reservoir is spurting a fountain, sending roughly 500 litres of water down the drain every hour. At Kokar Chowk and Kantatoli Road, the situation is no different. The leaking pipes there are leading to wastage of around 1,000 litres per hour. The total wastage in Ranchi roughly works out to around 40,000 litres per day.

But engineers in the department claim that central guidelines allow a wastage of 10 per cent of the total water released per day. Given that the department releases 3.75 crore litres a day, the wastage due to leaking pipes, they claim, was negligible. What he perhaps meant was that tending to small punctures might augment water pressure through the rusted pipes and cause them to burst.

Corrosion leading to pipeline leakage leaves parts of Tiswadi parched for 3 days

A corroded, leaking joint on the 900mm Opa-Panaji water supply line at Carambolim was the cause of the problem


PANAJI: The capital city of Panaji and surrounding areas of Ribandar, St Cruz, Merces, Taleigao and Dona Paula reeled under an acute water shortage for the third day running on Saturday, putting residents under much distress.

A corroded, leaking joint on the 900mm Opa-Panaji water supply line at Carambolim was the cause of the problem. PWD had warned of a shutdown for May 24, but the repairs took over a day-and-a-half putting residents in acute discomfort. Flooded with calls from hapless residents from their respective wards, city corporators complained bitterly that PWD engineers were either not taking their calls or repeatedly giving false deadlines and that no water tankers had been pressed into service. PWD chief engineer (I) J Borkar on Saturday afternoon insisted that the department had released water in the morning itself.

There were reports that, cashing in on the problem, some private water tanker operators were charging as much as Rs 2,000 per trip. Worse, citizens were put on waiting lists by water tanker operators and one resident said his number was 300 on the list.

CAPpings - Corrosion of metals over a long time can cause breakdown and loss of the dental implant as well as health problems for the patient

Metallic ions released as the result of corrosion of dental implants react with other components of the body, leading to sensitivity, inflammation, and, ultimately, autoimmune disease.

Know Galvanic Cell (Battery) set up in Saliva - "Oral Galvanism"


Corrosion of metals over a long time can cause breakdown and loss of the dental implant as well as health problems for the patient.

BATTERY-MOUTH
Titanium implants constantly release metal ions into the mouth. This chronic exposure can trigger hypersensitivity, inflammation and allergies, as well as autoimmune disease in people with high sensitivity. The metal implants can become part of a charged battery. All that is needed to make a battery is two or more different metals and a liquid medium (electrolyte) that can conduct electricity. Metal implants, fillings, crowns, partials, and orthodontic appliances provide the dissimilar metals, and saliva in the mouth serves as the electrolyte. This phenomenon, called “oral galvanism,” creates two major concerns.

First, the electrical currents increase the rate of corrosion (or dissolution) of metal-based dental restorations. Even precious metal alloys continuously release ions into the mouth due to corrosion, a process that gnaws away at the metal’s surface. These ions react with other components of the body, leading to sensitivity, inflammation, and, ultimately, autoimmune disease. Increasing the corrosion rate, therefore, increases the chance of developing immunologic or toxic reactions to the metals.

These electrical potentials, especially those developed by implants, set in a chronic, degenerative and inflamed section of the bone, can disturb local physiology and affect the body’s entire regulatory ability through osseous, lymphatic, immune, vascular, endocrine, autonomic nervous and meridian systems.

A second concern is that some individuals are very susceptible to these internal electrical currents. Dissimilar metals in the mouth can cause unexplained pain, nerve shocks, ulcerations and inflammation. Many people also experience a constant metallic or salty taste, a burning sensation in the mouth, and insomnia.

CAPpings: Corrosion causes contamination of drinking water with sewer leading to Gastroenteritis outbreak in Bangalore

Corrosion causes contamination of drinking water with sewer leading to Gastroenteritis outbreak in Bangalore



A day after 12 patients were admitted to a private hospital with suspected gastroenteritis (GE), health officials on Wednesday insisted the situation was “under control” even as four new cases were reported.

Of these four, two were admitted to K.C. General and two to a private hospital (Lakshmi Nursing Home) in Ramachandrapuram. According to K. Annamalai, Medical Director, Lakshmi Nursing Home, all the 12 patients admitted on Tuesday have been discharged. Two new cases were admitted Wednesday evening, while 11 others were treated as out-patients. The two patients have been put on fluids as they were suffering from dehydration.

CONTAMINATION

R. Surendra, Bruhat Bangalore Mahanagara Palike's (BBMP) Deputy Health Officer (Gandhinagar), told The Hindu two patients were admitted to K.C. General Hospital Tuesday night and discharged on Wednesday. He attributed the rise in GE cases to drinking water being contaminated with sewage.

“The patients were mostly from the Okalipuram slum. The slum-dwellers have drawn illegal [water] connections and the underground drainage system is not sound. As the water pipeline is corroded, the chances of sewage mixing with drinking water are high.”
