Product Description

Front-Swing Spiral Welded Pipe Mill            

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. When the uncoiling, coil detaching, leveling, steel cutting and welding are working, the host machine needs to stop and wait. After the steel welding finishing, the host machine starts to work again. The front-swing spiral welded pipe mill adopts intermittent production method with advantages such as low investment, and simple convenient.

According to the different function of our products, the front swing spiral welded pipe mills are divides in to API standard model and national standard 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.
