About This Category

What Welded Steel Pipe Is Actually For

Welded pipe is formed from strip and joined along a longitudinal seam, which makes it economical in larger diameters and thinner walls.

For structural, water and low-pressure conveyance duties it does everything seamless does, at a materially lower cost per metre.

Welded Steel Pipe Questions

Is welded pipe weaker than seamless?

For the duties it is specified for, no. The distinction matters at high pressure, high temperature and in cyclic service, where standards call for seamless.

Can welded pipe be galvanized?

Yes. State whether coating is required internally, externally or both.

What lengths are supplied?

Standard mill lengths are normal; cut lengths are quoted with the order.
