is obvious from the names. Seamless tube is extruded and drawn from a billet while welded tube is produced from a strip that is roll formed and welded to produce a tube. Welded tube is considerably less expensive than seamless tube and is readily available in long continuous lengths. Although the working pressure of welded tube is

Manufacturing Process of Welded, Drawn and Seamless Pipe ...

The two major categories for tubing and pipe are seamless and welded. The major difference being the seam that is on a welded tube and not on a seamless tube just as the names indicate. Seamless pipe has the increased ability to withstand pressure; because there is no weld seam it is equally strong around the entire circumference.
