Helical Submerged Arc Welded Pipe (HSAW) mill line

Helical submerged arc welded (HSAW) pipes are made from HR coil, where the coil is welded spirally to give a shape of pipe through the HSAW mill line. One of the unique features of the HSAW mill is that it can manufacture pipes of same size or two different sizes simultaneously at a very high speed, thereby drastically reducing the delivery time. HSAW welded pipe mill line should make sure the pipes pass the water pressure test, welding seam cold bend test and tensile strength test.

We can provide the whole set of machines for producing various diameters of steel pipes.
