What is HSAW

What is HSAW

In the steel pipe industry, HSAW stands for Helical Submerged Arc Welded Pipe; these pipes are manufactured using hot-rolled steel coils as raw material via the SAW (Submerged Arc Welding) process. The terms HSAW, SSAW, and SAWH are used interchangeably to refer to spiral-welded steel pipes characterized by a helical weld seam along the pipe body.

In many international standards and project specifications, HSAW, SSAW, and SAWH are treated as the same product.

The production process involves: uncoiling hot-rolled steel coils, leveling and edge trimming, spiral forming, internal welding, external welding, ultrasonic testing, hydrostatic testing, and anti-corrosion treatment.

For questions regarding the HSAW pipe production process, please visit our SSAW product details page, which includes information on production parameters, inspection procedures, data tables, and more. Please feel free to contact us if you have any inquiries.
