Kirloskar Corrocoat Private Ltd (KCPL) has been operating in India since 1993 using Corrocoat coating systems to protect all manner of infrastructure and assets in many industry sectors.
KCPL, was asked to protect 1.3m and 1.5m diameter cold water inlet and outlet pipes for the Tangedco Ennore Power Project in South India. Polyglass 100, a coating developed specifically for immersed marine conditions, was specified to provide protection against the seawater the pipes would be carrying when installed. The work was to be completed at several of the pipe manufacturer’s facilities right across India so the project proved to be a test of KCPL’s organising and scheduling skills.
The internal surfaces of the pipes were abrasive blast cleaned to Sa2½ before Polyglass 100 was applied in multiple coats to achieve a DFT of 1000μm. The pipes were then welded together and erected on site in their final positions where KCPL coated the joints – again with Polyglass 100.
The project was completed over a period of six months involving a team of 20 personnel. In total a surface area of some 51,100 m2 was corrosion protected– quite an achievement.
