Core Product
SSAW Spiral Welded Pipe
Continuous helical submerged-arc welded pipe for large-diameter water, energy, marine, and infrastructure lines.
Overview
Built for the application, not just the catalog
Our SSAW line covers outside diameters from 200 mm to 3,800 mm and wall thicknesses from 5 mm to 25 mm. Standard lengths are 6 m and 12 m, with custom lengths available for specific transport or installation constraints.
Every length is produced with heat-number traceability, hydrostatic testing, and dimensional inspection. Welds are checked by ultrasonic or radiographic testing according to the selected standard and project requirement.

Advantages
Why buyers choose this product
Long Continuous Lengths
Helical forming supports long production runs with fewer girth welds than plate-rolled alternatives.
Wide Diameter Range
One production line can cover both utility sizes and very large-diameter transmission pipe.
Consistent Weld Quality
Submerged-arc welding on both sides gives deep, uniform weld penetration.
