SSAW Spiral Welded PIPE 42IN SCH80 API X42

SSAW, HSAW Spiral submerged arc welding(SSAW) is its forward direction and forming tube centerline hose reel molding angle (adjustable), side molding edge welding and weld them into a spiral. SSAW pipe is made of hot rolled coiled steel by automatic submerged arc weld under normal atmospheric temperature.

These pipes mainly used in petroleum and natural gas industry to transport flammable and non-flammable liquid and steel construction.
