Electric-Resistance Welded (ERW) Steel Pipe Manufacturing Process
High-frequency straight seam electric-resistance welded steel pipe(erw steel pipe) is hot-rolled coil after forming machine, the use of high-frequency current skin effect and proximity effects, the tube edge heating and melting, squeeze roller under pressure welding to achieve production.
High-frequency resistance welding steel pipe, welding pipe and ordinary welding process is not the same, the weld is made of the base metal melt from the body, the mechanical strength is better than the general pipe. Smooth appearance, high precision, low cost weld high and small, favorable 3PE anti-corrosion coating. There are significant differences in the welding methods between high frequency welded pipe and submerged arc welded pipe. As the welding is done instantly at high speed, the difficulty of ensuring the quality of welding is much higher than that of submerged arc welding.
