Spiral Welded Pipe

Spiral Welded Pipe
Spiral welded pipe (SSAW) is a type of steel pipe made by coiling hot-rolled steel strip at a specific spiral angle and then welding it.
Compared to the straight seam welded pipe you just learned about, spiral welded pipe has unique advantages in large-diameter and high-pressure transmission applications.

The surface treatment of the steel pipe is very good, the anti-rust coating is uniform and firm, and the dimensional accuracy is very high. It does not require secondary processing at all, which greatly saves our time and costs.
