Resistance welding is a common method for joining tubes. The Erw tube mill is suitable for producing various types of steel tubes with different materials, such as common carbon steel, stainless steel, galvanized steel, and so on. The manufacturing process of Erw welded tubes is highly efficient and

In the steel pipe industry, ERW (Electric Resistance Welded) high-frequency welded pipes and seamless steel pipes are two common product types. They have some obvious differences in production technology, performance characteristics and scope of application.Of course, ERW (resistance welding) high-f
