Product Description

Spiral/Helical Submerged Arc Welded (SSAW/HSAW) Steel Pipe

HSAW (or “spiralweld”) large line pipe is characterized as a steel pipe having a DSAW seam the entire length of the pipe in a spiral form. HSAW is produced using hot-rolled coil that is formed into a hollow cylinder by twisting the skelp as it is unrolled (in the same manner that the cardboard core in a roll of paper towel is formed) and then welded as the edges come together using an automated SAW process both inside the cylinder and outside the cylinder. The end product is a welded pipe.

Stages in the HSAW production process typically include: de-coiling and leveling; skelp end welding for continuous rolling; edge trimming and bevelling; forming and tack welding; cutting to length; skelp and repair welding; inside cleaning of pipe; internal and external SAW; further inside cleaning; weld seam removal at pipe ends; and beveling of pipe ends.

HSAW large line pipe production processes also comprise a number of quality control steps including, but not limited to, the following: skelp and edge ultrasonic testing; sampling and destructive testing; inspection of SAW; tack weld inspection; hydrostatic testing; ultrasonic testing; x-ray weld inspection/filmless radiography; final inspection; and generation of certificates. The complainant employs both the LSAW process and the HSAW process for its production of large line pipe.
