Steel factoryHunan Standard Steel Pipe Co.,Ltd owns 3 sets of hot -rolled seamless steel pipe production line and 2 sets of cold drawn seamless steel pipe production line with annual production capacity of 200,000 tons, the size range is from 73mm to 630mm. The continuous mandrel rolling process and the push bench process in the size range from approx. 21 to 178 mm outside diameter. The multi-stand plug mill (MPM) with controlled (constrained) floating mandrel bar and the plug mill process in the size range from approx. 140 to 406 mm outside diameter. The cross roll piercing and pilger rolling process in the size range from approx. 250 to 660 mm outside diameter.

It rolls the strip or plate then welds the tube to steel pipes by HF welding or submerged arc welding. Welded pipe making machine is composed of uncoiler, leveling machine, butt welder, loop, straightening machine and high frequency equipment. Our innovative production line and each single unit of the production line are not only economical but also practical. The complete production line adopts ZTF technology when producing round pipe, the customer shall reduce 60% expense on tooling.
