The introduction of Coil for welding machine:
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.
According to the different function of our products, the spiral welded pipe mills are divides in to API standard model, national standard model and special purpose 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 equipment also are very high. National standard model produces the pipe used for short distance delivery of natural gas or water, the pipeline construction in the city, the structure pipe, column 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 is used for some special purposes. For example, our company developed the special 60~214 mill aiming at the function of petroleum filter.
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*80. Besides, special material such as the stainless steel is included. All of them cover all the mills.
