WELD OVERLAY TECHNOLOGY
SWI Valve Co., Ltd.
SWI's fully automated robotic welding system offers a cost effective solution compared to solid corrosion resistant alloys for valves 6" and larger. Valve bodies, balls, stems & trunnions may all be overlaid with corrosion resistant alloys such 25% Cr Duplex or Inconel 625.
Where highly corrosive or erosive services are involved, the life expectancy of a valve can be considerably extended by the application local weld overlay to critical seal areas or full internal cladding to valve internal/process wetted surfaces.
