Category: SSAW Steel Pipes

SSAW Steel Pipes is short for Spiral Submerged Arc-Welding Pipe. Also called HSAW pipe or Helical SAW. Its welding line shape like a helix. It is using the same welding technology of Submerged Arc-Welding with LSAW pipe. Differently SSAW pipe is spiral welded where the LSAW is longitudinally welded. Manufacturing process is rolling the steel strip. To make the rolling direction have an angle with the direction of the pipe center. Forming and welding, so the welding seam is in a spiral line.

The SSAW pipe diameter range is from 20 inch to 100 inch, 406 mm to 2540 mm. The advantage part is we can get the different diameter of SSAW pipes with the same size of the steel strip. There is a wide application for the raw material steel strip. And welding seam should avoid the primary stress, good performances to bear the stress.
