Weld Overlay Strength

Weld overlay production range includes: oil and gas wellhead equipment, Christmas tree, API6A

Valve, pressure vessel parts, Hydrogenation reactor unit as well as all require the ability of corrosion

ordinary pipes, valves, flanges and pipes and pipe fittings etc. All the weld overlay process is

programmed, and the equipment automatically completed weld overlay.
