SUBSTRATE
Cast Iron body
CHALLENGE
The original split case halves didn’t match with a misalignment of 35-40mm causing cavitation in the anti-swirl veins, we recommended a profile alignment and the addition of composite reinforcing
SOLUTION
Repair mechanical damage. We then applied RB 364, a glass flake filled vinyl ester consolidated with composite reinforcing to areas of the casing that had been damaged by external factors to return it to its original strength.
SCOPE
Onsite hotwash and scrub of internal lining to identify damage for repair
Whip & Spot Abrasive blast damaged areas
Application of RB 364 to bare metal areas of internals
Reprofile using chopped strand and RB 364
Apply RP 500 in two coats @ 250µm each
RL 500 PF to externals in two coats
