Description

Welded pipe is produced by rolling stainless steel strip into a tube and then welding it along its entire length. After welding, the weld, or bead, can be finished by cold rolling and forging or left as it is.

Cold forming produces smoother surfaces and tighter tolerances. Welded tubing can even be drawn like seamless tubing to provide a better weld and surface finish. Welded tubing can also be produced with thinner walls on larger diameters than seamless tubing. Because welded tubing requires less machining, it is typically faster to produce and less expensive than seamless tubing.

The disadvantage of welded tubing is in high pressure and heavy wall applications. The long weld creates a stress concentration point that reduces pressure ratings to 80% of comparable seamless tubing. In addition, the stainless material used to make welded tubing must be thin enough to roll effectively. Therefore, heavy wall tubing is less feasible than welded tubing.
