generally 6 meters in length. Welded steel pipe production process is simple, high production efficiency, variety specifications, equipment investment is small, but the general strength is lower than seamless steel pipe. The common materials for welded pipe are: Q235A, Q235C, Q235B, 16Mn, 20#, Q34 5, L24 5, L290, X4 2, X4 6, X60, X80, 16Mn, etc. Welded steel pipes are made of steel plates or strips, which are divided into furnace welded pipes, resistance welded pipes and automatic arc welded pipes.
