The Quality Comparison Of SSAW And LSAW Pipes

The main differences between SSAW and LSAW pipes are in their length and pattern of welding seam. SSAW pipes have longer welding seams than LSAW pipes and so have a higher risk of seam defects. Meanwhile, for SSAW, the welding seam is at a certain angle with the orientation of the principle stress. This shortens the faulty welding joints of an SSAW pipe when compared with an LSAW pipe of an equivalent length. (This reduces the danger of a single defect). The disadvantage and advantage mentioned above cancel out each other. The difference between the orientation of the welded seam and the special directivity of the major raw material of a SSAW pipe enhance its resistance against fracture.
