SSAW Steel pipe(Spiral steel pipe), also known as spiral welded pipe, is made by rolling low-carbon structural steel or low-alloy structural steel strip into a tube blank at a certain spiral angle (called forming angle), and then welding the tube seams. It can produce large-diameter steel pipes with narrower strip steel.

Manufacturing process of SSAW steel pipe:
Raw Material Inspection → Strip Joining → Pre-forming Treatment → Conveyor Control → Roll Forming → Gap Control → Welding → NDT (Non-Destructive Testing) → Single Pipe Cutting → Batch Inspection → Defect Repair → Weld Inspection → Hydrostatic Testing → End Finishing
Packing & Loading
→SSAW Pipe is transported in containers
(Nesting Packaging): Large-diameter SSAW pipes can be nested within one another, similar to Russian dolls, to utilize the internal space of larger pipes and minimize the volume of the cargo. This is a "game-changer" for reducing freight expenses and improving supply chain efficiency.
SSAW Pipe is transported by bulk carrier
