Introduction: Spiral welded carbon steel pipe production line 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 welded the spiral welding seam by the submerged arc welder. It is also called SSAW pipe mill. Process flow

Reference Project HUAYE LH2000-2540-25 Spiral welded carbon steel pipe production line
The spiral pipe production line was installed at a port city in east China, supplying stable production of piling pipes with up to 65 meters long. The pipes were put on to ships after simple surface process and were installed under water for bridge construction purpose. HUAYE LH2000-2540-25 was then refined and improved after several installation and a couple of other heavy duty model mills were derived from the project.
