Because of the different forms of welding, pipe into LSAW and spiral welded pipe. Because the shape of the ends of the pipe, welded steel pipe divided into circular pipe and shaped (square, flat, etc.) pipe.Dimension of Welded Steel Pipe:ERW welded steel pipeOD21.5mm - 508mm,Wall thickness: 0.8mm - 26mmSpiral welded steel pipeOD219mm - 1520mmWall thickness: 5mm t- 30mmPetroleum casing pipeOD60.3mm – 508mmWall thickness: 4mm -16mm
