325mm-1420mm spiral welded pipe machine:, Coil width:325mm-1420mm, Coil thickness:6mm-22mm, Coil weight:30 tons - details see: https://www.machineto.com/325mm-1420mm-spiral-welded-pipe-machine-10141450

The introdution of spiral welded pipe units:

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

Acccording to the diferent function of our products model. API standard model mainly produces the delivery pipe with petroleum or natural gas (long distance). The material and quality of the steel pipe need to be very good. The requirements for mill equipment and testing quipment also are very high.National standard model produces the pipe used for short distance delivery of natural gas or weter,the pipeline construction in the city, the structure pipe, xolumn pipe and so on. The requirements for the material and quality of the steel also are very high, second only to that of API standard. Special purpose mill used for some special purposes. For example, our company developed the special 60~214 mill aiming at the funtion of petroleum filter.

The specification of our products is from Φ90 to Φ3500. The thickness of the wall is from 1mm to 25.4mm. The material of our products is from Q235 to Q235 *80. Besides, special material such as the stainless steel is included. All of them cover all the mills.
