Resistance welding has the characteristics of high production efficiency, low cost, material saving and easy automation, so it is widely used in aviation, aerospace, energy, electronics, automobile, light industry and other industrial sectors, and is one of the important welding processes. The biggest difference between ERW steel pipe and seamless steel pipe is that ERW has a weld, which is also the key to the quality of ERW steel pipe. ERW pipe is a “high-frequency resistance welded steel pipe”, which is different from the welding process of ordinary welded pipe. The weld is made by melting the base metal of steel strip body, and its mechanical strength is better than that of ordinary welded pipe.
1) Economy Benefit: ERW steel pipe is less expensive than seamless steel pipe.
2) High Precision: ERW steel pipe has a closer tolerance of wall thickness when compared with seamless steel pipe.
ERW steel pipe is widely used in aviation, aerospace, energy, electronics, automobile, light industry and other industrial sectors. ERW steel pipe is used to transport oil, natural gas and other vapor-liquid objects, which can meet various requirements of high and low pressure. At present, it plays an important role in the field of transportation pipes in the world.
