ERW China manufacturers, ERW Chinese manufacturers produce "high-frequency resistance welded steel pipe," and not the same as an ordinary pipe welding, its weld joint is made of base metal melting and the mechanical strength is better than the ordinary pipe. ERW means resistance welding, which is with high efficiency, low cost, material saving, easy automation features and other features. Therefore, It is widely used in aviation, aerospace, energy, electronics, automobile, light industry and other industrial sectors and is an important process of welding one.
