We CAN Control Corrosion in India group is a connection platform for knowledge transfer leading to exchange of proven corrosion analysis methodologies and control technologies developed in and out of India and establish Global Collaboration for Corrosion Control through our technology group on Linkedin. Our group provides the platform to bridge Indian Diaspora knowledge with homeland talent pool.
Our Discussion in "We CAN Control Corrosion in India" Network
What is the limit of chloride in recirculating water having copper metallurgy? How does chloride attack on Copper and what is the limit we should maintain? Give some reference also.

How do we view Corrosion problem? Is it for Industries only?
Background: My collegemate from Mechanical discipline approached our alumni network to resolve his domestic concrete corrosion issues.
Problem: How to counter the problem of corrosion in the reinforcement rods of roof/ceiling concrete?
The layer of concrete beneath the reinforcement rods in concrete roof, has got bulged and I am planning to repair it, by removing the loose material, and do replastering. 3 years back, I removed the complete weathering layer over the roof (including brick chips and sintered / country tiles) and re laid it, suspecting the weathering layer, after seeing the dampness in few areas, at the bottom of the ceiling. However, it seems that the mason has not done a perfect job.
Could you suggest any method of applying some protective coating on the corroded reinforcement rod, after removing the loose layer and before taking up the re-plastering.
I was told that once corrosion sets-in in the reinforcement rods, it can't be prevented totally.
Action: On our recommendations he approached some suppliers in the market who manufacture chemicals for rehabilitation of corroded concrete structure. He couldn't get the right info.
His experience: The manufacturers loose interest the moment I say it is for repairing a small patch of roof concrete, in an individual house. Probabaly they may be interested if the quantity involved is high.
The Senate unanimously approved a pipeline safety bill Monday that stemmed from a spate of incidents, including last year's deadly explosion in San Bruno that killed eight people and destroyed 38 homes.
The measure had been held up by Sen. Rand Paul (R-Ky.), who lifted his hold after reaching agreement with Democrats to add a key recommendation from the National Transportation Safety Board.

There are instances of defining setpoints like 2 mpy for the coupons installed at the return line of cooling water for characterizing the whole treatment and less than 1 mpy for terming the observed general corrosion rate as "Low" for process circuits based on Industry Practice/International Standard. These setpoints do not always reflect current design criteria including the changes made in original design for future operation. What should be the appropriate relational grading technique from the standpoint of: 1.Asset Owner, 2.Corrosion Control Service Providers (CSP), 3.Process Designer, 4.Corrosion Management Consultants/Auditors and 5.Corrosion Researchers to accommodate "uncertainties" arise during the regular operation?
700 million litres of water per day is lost due to leakages along the 400 km of ageing pipeline network or by way of illegal connections in Mumbai.
BMC plans to outsource pipe leak detection
Of the 3,400 million litres of water supplied to the city every day, a whopping 700 million litres is unaccounted for. This means that it is either lost due to leakages along the 400-km of ageing pipeline network or by way of illegal connections.
In an effort to curtail leakages along water pipelines that lead to a loss of about 20 per cent of the total water supplied to the city, the BMC is mulling the option of outsourcing the work. Despite numerous efforts in the past to curb leakages either by forming a ‘leak detection squad’ or by planning to procure modern leak detection equipment, senior civic officials now feel they should appoint private firms to plug leakages.
Our Observation: Is there any effort made to identify the cause of leakage? Corrosion of water pipeline is one of the prime causes for huge loss in water and also affects the quality of water supplied to the public. It is highly advisable to have a corrosion research study for the quality of water and pipeline material chosen for distribution system.
India R&D 2011 - “Industry Academia Linkages” , November 2-3, 2011 at India Habitat Centre, New Delhi
Industry academia linkages or the lack of it has long been a topic of discussion. India is expected to be one of the leading nations in innovation economy. The universities will have to play a greater role in R&D and innovation strategy of industry, besides being the cradle of skill creation and development. We are pleased to inform you that FICCI in partnership with Department of Science and Technology (DST), Govt. of India is organizing a two-day conference and exhibition India R&D 2011 with the theme - “Industry-Academia linkages” on November 2-3, 2011 at India Habitat Centre, New Delhi. The objective of the conference is to bring industry and academia together to define research priorities. The conference will also delve on ways of creating adequate IP ecosystem and share learning’s from the MNC experience, which have been instrumental in animating the aforesaid linkages in India. Conference brochure along with Registration Form may be downloaded from http://www.indiarnd.com/. We are happy to invite you for this programme. May I, request you to kindly send your registration form with complete details & the requisite fee to Mr. Gaurav Gaur, Asst. Director, FICCI, or confirm at email@example.com. Please feel free to contact us for any further information/clarification. Look forward to your kind confirmation.

Cairn Lanka, a wholly owned subsidiary of Cairn India, has discovered natural gas with its CLPL-Dorado-91H/1z well offshore Sri Lanka.
Situated in waters measuring 1,354 meters deep, the discovery well was drilled on Block SL 2007-01-001, in the Mannar Basin offshore Sri Lanka. Cairn contracted the Chikyu drillship to drill the exploration well.
