Spiral welded pipe is manufactured from steel coil. The coil is unwound and then welded while it is being turned into the shape of the pipe. Changing the angle of the spiral and the thickness of the coil is all that is needed to change from one pipe size to another. The two sides of the double submerged arc weld penetrate the full thickness of the steel to ensure the strength of the finished pipe. Full scale tests have shown that high quality spiral welded pipe is as strong as API pipe. The strength and flexible manufacturing of spiral welded pipe make it the product of choice for a variety of applications.

SSAW Pipe (Spiral Submerged Arc-Welding Pipe), also called HSAW pipe (Helical SAW), welding line shape like a helix. It is using the same welding technology of Submerged Arc-Welding with LSAW pipe. 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.

SSAW pipe (HSAW Pipe) Size range and Features

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.

The disadvantage is the bad physical dimension, welding seam length is longer than the pipe length, easy to cause the defects of cracks, air hole, cinder inclusion, partial welding, welding force in pulling status.

Applications of SSAW pipe

For oil and gas pipeline systems, but in petroleum design specification, the SSAW pipe / HSAW pipe could only be applied in class 3 and class 4 areas. Construction structure, water transport and sewage treatment, thermal industry, buildings etc.
