Non-destructive Testing of ERW Straight Seam Steel Pipe

Jun 29, 2020 · Basic requirements for the appearance of ERW straight seam steel pipe welds Before the non-destructive testing of straight seam steel pipes(ERW pipe), the appearance inspection of welds should meet the requirements. The general requirements for the appearance of straight seam steel pipe welds and the surface quality of welded joints are as follows:Petrosadid Electric Resistance Fusion Welded (ERW and ERW steel pipe is manufactured through low or high frequency resistances Electric Resistance. Welding seam is in longitudinal. During the ERW pipe welding processes, the electric current will make the heat when flow through the contact surface of the welding area. It will heat the 2 edges of the steel to a point that the edges can form a bond.Pipe Manufacturing Process Methods for Seamless & Welded A welded pipe can be manufactured in large sizes without any upper restriction. Welded pipe with filler material can be used in the manufacturing of long radius bends and elbow. Welded pipes are cheaper with compared to the seamless pipe and also Weak due to the weld. There are different welding methods used to weld the pipe. ERW- Electric erw straight seam welded pipe q195

The Difference Between the Straight Seam Welded Pipe

Seam welded pipe production technology is simple with high production efficiency, low cost and rapid development. The strength of the spiral welded pipe is generally higher than straight seam welded pipe, and can adopt a narrow billet to produce larger diameter welded pipes, and it can also use the billet with the same width to produce the different pipe diameter welded pipe.The Difference Between the Straight Seam Welded Pipe and erw straight seam welded pipe q195General welded pipe is used to transfer low pressure liquid. It is made of Q195A, Q215A, Q235A steel and it can also be made of other mild steel. Steel pipe should have the text on pressure, bending, flattening and so on, and it has a certain request on the surface quality.The difference between ERW, SSAW, LSAW(UOE) Steel pipe erw straight seam welded pipe q195Straight seam high-frequency welded pipe (ERW) is divided into two types of induction welding and contact welding according to different welding methods. Hot-rolled wide-gauge steel coil is used as raw material, after pre-bending, continuous forming, welding, heat treatment, sizing, straightening, Cutting and other processes, compared with spiral welded pipe with a short weld, high dimensional erw straight seam welded pipe q195
