ERW Pipe Mill Line

Our ERW pipe mill line has following features such as lower labor intensity and high production capacity. Compared with other competitor's , one of the advantages of our mill line is that our quick-change system can shorten the time of changing rollers on machines, more efficient than others’.

Description

ERW Straight Seam Round Pipe Mill Line        

ERW stands for Electric Resistance welding. Different with other welding method ERW steel pipe is welded by melting the steel material itself and joining together as a pipe. This is good for the pipe mechanical performance. Our ERW pipe mill line has following features such as lower labor intensity and high production capacity. Compared with other competitor's , one of the advantages of our mill line is that our quick-change system can shorten the time of changing rollers on machines, more efficient than others’. And also, the pipes coming out from our machines are smooth on the surface and can bear particular pressure.
