Stainless Steel Piping – Offshore Platform

The operators of an offshore platform in the Gulf of Mexico were dissatisfied with the performance of the coating system they were utilising for stainless steel pipes. As a result, new paint trials for two alternative coating systems against the current system were to be carried out.

The coating systems had to have high adhesion to the stainless steel substrate, with minimal surface preparation. Application would be carried out in adverse weather conditions and in very high humidity.

For accurate comparisons to be compiled, the surface preparation method (mechanical) and application conditions were to remain constant for all three systems.

Chemco’s unique wet & rust tolerant primer/finish Epo-chem™ RL 500PF was applied to the mechanically prepared surface in one coat. The current system was applied in three coats, whilst the other alternative system was applied in two coats.

The Chemco system was applied in the shortest time and offered the longest pot life. There are also no humidity or dew point restrictions with the Chemco system. Upon completion of the trial, the client stated that their product of recommendation would be Chemco’s Epo-chem™ RL 500PF. After two years of service the project was inspected and the coating inspector stated that the Chemco system was still in perfect condition.
