Premature Failure of 316L Stainless Steel Pipes

OVERVIEW:    New 316L pipe failed after just two months in operation, causing a total plant shut down.

Quick response by Chemcote restored production without having to fabricate new pipes.



Ambient temperature seawater


Forged 316L SS elbow & pipe section


Pitting corrosion in new stainless steel pipes caused holes straight through the steel. Plant unable to operate without these pipes. An immediate and long term solution was required.


Pipes were removed from service.

Machine rebates to allow coating application onto flange face preventing crevice corrosion.

Apply low MVT (moisture vapour transmission) rated coating, in this case, a glass flake-filled vinyl ester Chem-tect™ RB 364 up to 1,000µm dry film thickness

Reprofile deep pitting holes using composite repair techniques

Reinforce pitted areas and internal lining with basalt fibre weave matting
