US - Automotive Industry - Priority for effective corrosion resistance is felt in the new truck design - 2014 Silverado Most Rust-Resistant Chevrolet Truck Yet, GM Says


Maintenance of Truck is the key for improving the corrosion resistance and extending the life of truck




2014 Silverado Most Rust-Resistant Chevrolet Truck Yet, GM Says

New truck design starts with zinc-coated (galvanized) steel for the roof and all body panels except the hood, which is made of an aluminum alloy that reduces weight and provides corrosion resistance.

DETROIT – More than half of light-duty pick-up trucks on the road are now 11 years or older. To help build on the Chevrolet Silverado’s reputation as the most dependable, longest lasting full-size pickup, engineers designed the 2014 Silverado to be the most corrosion resistant Chevrolet truck ever.

The 2014 Silverado starts with zinc-coated (galvanized) steel for the roof and all body panels except the hood, which is made of an aluminum alloy that reduces weight and provides corrosion resistance. At every step of the design and manufacture of the new Silverado, materials and production processes were selected to help minimize deterioration over time.

“Silverado’s corrosion protection measures provide superior defense against elements in the environment, whether driving through farm fields, on construction gravel, or down a snow-covered highway,” said Mark Yergin, engineering group manager, General Motors Corrosion Engineering and Labs. “The new Silverado is our strongest truck yet, affording us the confidence that the truck will continue to meet customers’ needs throughout its life.”

Additional 2014 improvements over previous models include:

¦All new body structures designed to minimize the potential for corrosion.
¦Improved hem flange sealing on the doors and hood, and additional underbody flange sealing help keep the joints of the truck dry, discouraging deterioration that might occur from moisture
¦Extensive and improved chassis corrosion protection that enhances the truck’s appearance and lengthens the life of underbody components
¦Anti-chip protection on the lower body side for extra protection from stones or gravel.

The effectiveness of these changes was borne out during extensive proving ground testing at exposure levels higher than most drivers ever experience. The months of accelerated testing these trucks undergo is equivalent to more than 10 years on the road.

Post-test evaluations of the trucks, including the search for and elimination of corrosion even on areas of parts customers never see, helps ensure the overall vehicle performance.

CAPpings - India - Water Leakage - Leak in pipeline briefly disrupts water supply in Coimbatore - Timely response restored the supply

Water supply from Pillur I project was temporarily affected after a leak was detected in the main supply line near Karattumedu near Saravanampatti. Timely response of water management authorities restored the supply



COIMBATORE: Water supply from Pillur I project was temporarily affected after a leak was detected in the main supply line near Karattumedu near Saravanampatti. The TWAD board officials were informed and they rushed to the spot and carried out maintenance work. Water supply was restored by Thursday evening.

"We have carried out maintenance work and the leak has been closed. The supply was completely restored by 5.30 pm," said Iqbal, executive engineer, Tamil Nadu Water Supply and Drainage Board (TWAD).

Residents found water gushing out of the main supply line which is connected to the master reservoir at Ganapathy from where water is supplied to corporation wards.

"The TWAD maintenance team was notified and they started maintenance work at the identified spot. Water supply has been completely restored in city limits," said a senior corporation official.

The supply to eastern parts of the city is dependant on Pillur water and was temporarily affected after the valve was closed to carry out maintenance on the damaged pipeline.

CAPpings - India - Water Leakage - Pipeline leak inundates colony in Iyyappanhangal, Chennai - Valve Failure and Pipeline Damage are identified as the causes

Pipeline leak inundates colony in Iyyappanhangal, Chennai - Valve Failure and Pipeline Damage are identified as the causes.  Water seeped into the settlements at EVP Park Avenue in Iyyappanhangal after a valve in a pipeline carrying drinking water from Chembarabakkam lake to Chennai burst early morning on Saturday


Water seeped into the settlements at EVP Park Avenue in Iyyappanhangal after a valve in a pipeline carrying drinking water from Chembarabakkam lake to Chennai burst early morning on Saturday

Residents of Iyyappanthangal on the outskirts of Chennai woke up to knee-deep water outside their houses on Saturday morning after the valve on a major pipeline carrying drinking water to the city from the Chembarambakkam lake allegedly gave way.

The flooding resulted in a complete blackout in the area as the Electricity Board disconnected power supply to ensure safety. Power was restored after over eight hours when a considerable amount of water was pumped out by the evening.

Residents said within a matter of an hour, the streets in the colony were filled with at least 3 feet of water. The water made its way into several households, forcing the residents to stay indoors till evening when three motor pumps drained out a fair bit of the stagnated water.

A senior official at the Chennai Metro Water told Express there was no “burst” as claimed by the residents and it was only a leak in a major pipeline as a valve gave way.

The official said almost immediately after the leak was reported, the supply at Chembarambakkam pumping station was stopped. “What came on to the streets was water already in the pipeline that ran several kilometres. The leak has now been plugged,” the official added.

CAPpings - India - Water Leakage - Improper interconnection design followed by contractor and no vigilance on pipe laying work are leading the way for leakage - Residents protest as water woes continue in Kerala


Improper interconnection design followed by contractor and no vigilance on pipe laying work are leading the way for leakage


Residents protest as water woes continue

Though Kerala Water Authority (KWA) has claimed that the new  pipeline from SN Junction to Puthiyakavu was laid to resolve the water scarcity in Tripunithura, it proves otherwise in some areas.

The residents at Thekkumbhagam said they have been facing acute shortage of potable water for the past two months.

While KWA authorities blame the leakage at spots where the pipes interconnect, the technical committee members of Tripunithura Rajanagari Union of Residents Association (TRURA) say the KWA has not ensured perfection in pipe-laying work.

“The KWA has not monitored the pipe-laying work and they allowed the contractor to conduct the interconnections by himself. As a result, there are leakages at some spots and there is a chance that it might get worse,” they said.
