508-2400mm carbon steel pipe making machine:, diameter: 508mm-2400mm, wall thickness:8mm-25.4mm, coil width: 1200mm-2000mm - details see: https://www.machineto.com/508-2400mm-carbon-steel-pipe-making-machine-10081868

The introduction of 508-2400mm the spiral welded pipe mill:

The steel coils are unfolded and leveled by the mill equipment. And they are sent to the forming machine in a certain angle. Supplemented by a certain angle, the continual pipes are formed in the principle of three-roll rolling machine. Continual spiral welding is welded by submerged-arc welding machine.

The specification of our products is fromΦ9 0 toΦ3500. The thickness of the wall is from 1mm to 25.4mm. The material of our products is from Q235 to Q235, X80. Besides, special material such as the stainless steel is included. All of them cover all the mills.
