Smaller diameter welded pipes use straight seam welding、 while larger diameter welded pipes mostly use spiral welding; According to the shape of the steel pipe end、 it is divided into circular welded pipes and special-shaped (square、 rectangular、 etc.) welded pipes; According to different materials and purposes、 it is divided into welded steel pipes for mining fluid transportation、 galvanized welded steel pipes for low-pressure fluid transportation、 and electric welded steel pipes for belt conveyor idlers. According to the specifications and dimensions table in the current national standard、 the order is from small to large by outer diameter * wall thickness
