What Is Spiral Welded Pipe?

Spiral welded steel pipe is made of low-carbon carbon structural steel or low-alloy structural steel strip rolled into a pipe billet at an angle of a certain spiral line, and then the pipe seam is welded together.

Weight Calculation Formula

W = 0.0246615(D – S)S + 0.5

Note: W — theoretical weight per meter of spiral welded pipe, kg/m;
D — Nominal outer diameter, mm;
S — Nominal wall thickness, mm.

Wanzhi Steel carries out delivery of spiral welded pipes by actual weight or by theoretical weight. The specific situation is still subject to discussion. If you still have doubts about this, you can contact us for more details.
