Large Diameter Spiral Steel Tube (1220X12mm X 12meters)

Material of welded steel pipe adopt steel plate or steel strip, because of different welding processes and into the furnace pipe, welded (ERW) pipes and automatic arc welded. 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.
