Introduction of Electric Resistance Welded Pipe

Electric Resistance Welded Pipe is that after the hot -rolled rolling rolled plate is formed, it uses a high -frequency current skin collection effect and neighboring effect to heat the edges of the pipe blank to heat and weld it under the action of squeezing rollers to achieve production products. The Feature of Electric Resistance Welded PIPE is that: Large welding speed, small welding thermal affecting area, welding can not be cleaned up to the workpiece, can be welded with thin wall tubes, and can be welded with metal tube.

In fact, Electric Resistance Welded Pipe is not the same as the welding process of ordinary welded pipes. If you want to know about the different of them, you can read this passage: Difference Between ERW Pipe and Welded Pipe. The welds are melted from the parent material of the steel band. The mechanical strength is better than the general welded pipe. The appearance is smooth, high accuracy, and low welding seams in low cost, which is beneficial to the cover of 3PE anticorrosive coating. Electric Residence Welded Pipe is significantly different from the welding method of buried arc welded pipes. Because welding is completed at high speeds, the difficulty of welding quality is much higher than the buried arc welding method.
