Spiral Welded Pipe Mill

Description
Spiral welded pipe production line is mainly used to produce spiral steel pipes. The steel coils are unfolded and leveled by the spiral welded pipe mill. Then they are sent to the forming machine in a certain angle. Supplemented by a certain angle, the continual pipes are formed in the threeroll rolling machine. Continual spiral welding is performed by submergedarc welding machine.

Application
Spiral welded pipe production line suitable for producing spiral seam steel pipes is widely used in various fluids conveying such as petroleum natural gas, water as well as construction structural pipes and piling pipes. Production process of the welded pipe making machine is continuous production line and also the making machine can produce spiral welded steel pipe as per API standard in terms of quality.

Classification
1. According to the different functions of our products, the spiral welded pipe production line can be divided into API standard model, national standard model and special purpose model.
2. According to the different working method, the welded pipe making machine can be divided into frontalswing and backswing spiral welded pipe mill.
