Case Study

Client

Petrochemical, UK.

Scope of work

Upon inspection, the HSC split pump casing and cover were found to have suffered from severe erosion corrosion around discharge cutwater, discharge bend and stuffing box bores. The stationary wear ring landings had already been mechanically repaired by the client, so we were only required to build up the eroded areas with one of our coating systems.
