Manufacturing Process of ERW Pipe:

en10210 LSAW Pipe

High-frequency welding is the use of skin effect to make the high-frequency current energy concentrated on the surface of the workpiece; The proximity effect is used to control the position and range of the high frequency current flow route. The speed of the current is very fast, it can heat the edge of the adjacent steel plate in a very short time, melt, and realize the docking through extrusion each has its own advantages, but also has its own shortcomings. It is generally necessary to analyze specific choices according to specific circumstances.

The process of manufacturing Electric Resistance Welding(ERW) Pipe is as follows:

Open plate probe → Straightening milling → cutting forming → Butt welding cutting → Visual inspection → Ultrasonic inspection → X-ray inspection → Pressure test → Flat chamfering → Final inspection
