In valve industry

Coating on the basis of tungsten carbide, chromium carbide and nickel alloy is applied on spherical surface of steel and cast iron cock plug of stabbing valve. The refurbishment of steel and cast iron cock plug of stabbing valve is performed by stripping of surface of galvanized chromium coating, local repair of deep defects (dimple, dent, foundry reed mark), applying of corrosion-wear resistance coating. The complete production of new locking group with coating (plug, 2 seating) is possible for valve with metal seal “metal-to-metal”.

Coating on the basis of tungsten carbide, chromium carbide is applied on the sealing surface of rings, seat of stabbing valve “metal-to-metal”. Corrosion coatings is applied on the surface of housing and flange that contact with aggressive atmosphere.

Corrosion-wear resistance coating is applied  on working surface of gare valve parts that operating in the aggressive atmosthere with high content of H, S. The complete production of locking group (plug, 2 seating) with coating is possible by customer’s drawings.
