Weight (kg) per meter
Note: d (outer diameter); t (wall thickness)

Process Flow Chart.jpg

Production process: raw material uncoiling – flattening – end cutting and welding – looping – molding – welding – internal/external removal of welding beads – precorrection – inductive heat treatment – sizing and straightening – eddy current testing – cutting – water pressure inspection – acid pickling – final inspection (strict control) – packing – delivery


Features:
Straight welded pipes feature simple production process, high production efficiency, low cost and high development speed.
The intensity of spiral welded pipes is generally higher than that of straight welded pipes; welded pipes with larger pipe diameters can be produced by relatively narrow blanks; welded pipes with different pipe diameters can be produced blanks with the same width. However, spiral welded pipes have the length increase of 30~100%, as well as lower production speed compared with straight welded pipes with the same length.
