Spiral welded pipe making machine is used to uncoil and level the steel coil, and send the strip to forming machine by certain angle, then bend the pipe by certain angle based on three-roller forming principle, at last weld the spiral welding seam by the submerged arc welder. It is also called SSAW pipe mill.

Technical process:

 Loading coil—uncoiling—leveling—shearing and butt welding—rotary shearing—edge milling –delivering machine—prebending and guide plate—forming—inside welding— outside welding—cutting—pulling out—hydraulic testing—end facing and chamfering—X ray testing-marking--storing
