spiral welded pipe mill line roll forming machine

Product Description:

Structure of spiral welded pipe mill Description

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

Main Features of spiral welded pipe mill Description

According to the different function of our products,the spiral welded pipe mills are divides in to API standard model, nationalstandard model and special purpose model. API standard model mainly producesthe delivery pipe with petroleum or natural gas (long distance).the materialand quality of the steel pipe need to be very good. The requirements for millequipment and testing equipment also are very high. National standard modelproduces the pipe used for short distance delivery of natural gas or water, thepipeline 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 somespecial 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 1mmto 25.4mm. The materialof our products is from Q235 to X80. Besides, special material such as thestainless steel is included. All of them cover all the mills.
