The ERW steel pipe is fabricated through the electrical arc welding technology. Its welding seam is parallel to the longitudinal direction of the steel tube. We often call the product welded tube for short. The product often takes the carbon structural steel of 08, 10, 15 and 20 as well as carbon structural steel plate or strip of Q215, Q235 and Q255 as the raw material. Its production technology is simple and the production efficiency is high. With low cost, the ERW steel pipe is widely applied as the structural part, component, fluid transmission pipeline as well as for other purposes.
