Corrosion Audit

A detailed Summary of Corrosion Audit

5.Life of a material and remedies provided

Corrosion is the electrochemical deterioration of a metal because of its chemical reaction with the surrounding environment. While new and better materials are continuously being developed, this progress is offset, in part, by a more aggressive operational environment. This problem is compounded by the fact that corrosion is a complex phenomenon. It can take many different forms and the resistance of materials to corrosion can drastically change with only a small environmental change.

Corrosion is most often thought of as a slow process of material deterioration, taking place over a significant period of time (examples being general corrosion, pitting, exfoliation, etc.). Other forms of corrosion degradation can occur very quickly, in days or even hours, with catastrophic results. These forms (such as stress corrosion cracking, environmental embrittlement, and corrosion fatigue) depend on both the chemical and mechanical aspects of the environment and can cause catastrophic structural failure without warning.

SCC is mainly found in the CI pipelines, near the threads mainly.

In most of the cases corrosion is recognized by visual inspection.

 In some cases, the underground pipelines corrode very fast and sever. A two or three weeks ago there was a maintenance work going on in VH. There one of the pipelines under the garden was severely corroded. It was no more than a paper sheet remained. The reason was not proper care for corrosion was taken at the time of installation and this region was very much prone to corrosion, due to very high moisture content. So the metal corroded severely in 5-7 years only.
