"ERW welded steel pipe is a straight seam resistance welded pipe, abbreviated as ERW, which is used for the transportation of petroleum, natural gas and other vapor-liquid objects to meet the requirements of high and low pressure, and currently occupies a pivotal position in the field of the world's transportation pipe.


1. Ordinary welded steel pipe refers to the ordinary "submerged arc welded steel pipe", electrical engineering with "SC", can be used for water and gas pipe can also be used as a threading pipe, thicker.


2. Pipe line pipe is also known as wire pipe, thinner, with "T" that can only be used for threading pipe.


3.ERW pipe is "high-frequency resistance welded steel pipe", and ordinary welded pipe welding process is not the same, the weld is melted from the base material of the body of the steel strip, the mechanical strength is better than the general welded pipe.


ERW means resistance welding, resistance welding has high productivity, low cost, material saving, easy to automate and other characteristics, so it is widely used in, energy, electronics, automotive, light industry and other industrial sectors is an important welding process.
