Metal Repair

Compressor, engine and gearbox casing repair

Bearing-bore wear, split-line distortion and oil-leak paths at gasket faces retire compressor, engine and gearbox housings before the internals wear out.

The problem

The need for compressor, engine and gearbox casing repair

BHI Coatings performs compressor, engine and gearbox casing repair across Alvin and the Texas Gulf Coast. The internals still have life in them. The housing does not. Bores go oversize, split lines distort, and gasket faces start weeping oil, and one cracked or eroded casing takes the whole machine out of service. Replacing a compressor, engine, or gearbox casing means OEM lead times measured in months and a capital line item that dwarfs the original defect.

Our method

How BHI Coatings does compressor, engine and gearbox casing repair

We rebuild worn bearing bores and split-line faces cold, in our climate-controlled Alvin shop or at your site, with no welding heat to warp the casting. The crew prepares the metal, applies a machinable repair composite such as Belzona 1111 or 1121, then machines the surface flat and back to dimension. The bore and gasket face return to OEM tolerance without an arc.

Typically applied with Belzona 1111, Belzona 1121, matched to the service conditions.

The result

That housing goes back in during the outage already on your calendar, not whenever a replacement casting finally ships. The alignment datum stays where it was, and the long-lead capital purchase never gets written.
