Case Study: CC031: Oil cooler waterbox cover
Total repair and refurbishment of main oil cooler waterbox cover.
Client
Major refinery.
Application Date
December 2006.
Scope Of Work
The cooler water box covers would be considered
beyond repair for most companies, without the
established refurbishment expertise of Corrocoat.
Cracking of the cover was stabilized by performing
external metal stitch repairs. The internals were then
re-profiled, followed by blasting and coating using a
high build vinyl ester coating.

Coating credentials
We have a proven track record within the power
