Anti-cavitation and turbine coatings

The need for anti-cavitation and turbine coatings

BHI Coatings performs anti-cavitation and turbine coatings across Alvin and the Texas Gulf Coast. Cavitation is a hammer you cannot hear. Vapor bubbles form in low-pressure zones, then collapse against the metal and hammer it microscopically. Turbine runners, propellers, Kort nozzles, and stern tubes pit into a spongy, thinned surface over a campaign, and the damage keeps deepening until the component loses efficiency and heads for replacement.

How BHI Coatings does anti-cavitation and turbine coatings

We prepare the pitted surface, then line it cold with a resilient elastomer that flexes under each implosion and absorbs the energy instead of fracturing. The work fits the outage or dry-dock window you already have, in the field or in our climate-controlled Alvin shop. No welding and no heat into the casting, with a Belzona 2000 series elastomer where the service calls for it.

Typically applied with Belzona 2141, Belzona 1391T, matched to the service conditions.
