Difference between saw and erw pipe Welded Steel Pipe

ERW pipe is the hot rolled coil through the continuous roll forming, the use of high frequency current skin effect and proximity effects, so that the plate edge of the hot melt, squeezing the roller pressure to the role of pressure welding achieve production. Therefore, the residual stress of the erw pipe is small, and the residual stress is further released and reduced through the processes of heat treatment,
