An ERW (Electric Resistance Welding) mill is a type of tube mill that produces tubes and pipes through the process of electric resistance welding. The mill employs a continuous coiled steel strip as the raw material, which is uncoiled and fed through several forming and sizing rolls before being welded together by passing an electric current through the edges of the strip.
The electric resistance welding process is a high-speed, low-cost method of welding that is well-suited for producing large volumes of welded tubes and pipes in various shapes and sizes. In this process, an electric current is passed through the edges of the steel strip, which heats the edges and melts them together. The molten metal is then fused by applying pressure to the welded joint, creating a strong and reliable bond.
ERW tubes and pipes have a wide range of applications and are commonly used in industries such as oil and gas, automotive, construction, and plumbing. They are known for their durability, strength, and precision, and can be manufactured to meet various international standards and specifications.
