Rotating equipment repair and efficiency restoration
Flow-induced metal loss exposes fresh steel that the process chemistry then attacks, dropping the efficiency of pumps, fans and turbines.
The need for rotating equipment repair and efficiency restoration
BHI Coatings performs rotating equipment repair and efficiency restoration across Alvin and the Texas Gulf Coast. Flow-induced metal loss strips the protective surface off pumps, fans and turbines, and the fresh steel underneath is exactly what the process chemistry wants. The two failure modes feed each other while the unit slides down its efficiency curve. More power for less output, and the plant reads it straight off the energy bill.
How BHI Coatings does rotating equipment repair and efficiency restoration
BHI Coatings rebuilds the worn surfaces cold and overcoats them with an erosion-corrosion-resistant layer such as Belzona 1321 or 1391. We blast the substrate, bring lost metal back to the design profile, then lay on the barrier film that holds back wear and chemical attack together. The whole job cures at ambient temperature with no hot work.
Typically applied with Belzona 1321, Belzona 1391, matched to the service conditions.
The unit recommissions on its design curve without ever leaving the outage. The overcoat slows the next round of erosion-corrosion, which means efficiency holds longer between repairs.
