There are various kinds of steel pipes both in domestic and international markets actually. And the steel pipe can be classified into two main types, like welded steel pipe and the seamless steel pipe in accordance with their specific produdction methods actually. Although both of them are very popular among consumers, there are some differences between them actually.

For example, the welded steel pipe is bent in round, or square shapes and then welded into the other. The welded steel pipe is used in blank or strip. However, the seamless steel pilpe is a kind of hollow cross-section, and there is no seam around the circle, square, rectangular steel actually. It is made of the capillary tube through the hole, then through the hot-rolled, cold rolled or cold call is made. The seamless pipe can be used to convey fluid and it is an econonic cross-section steel. And the seamless steel pipe can be widely used in the manufactural parts and mechanical parts, such as drill pipe, automotive drive shafts, bicycle frames and construction using steel scaffolding and so forth.

The welded steel piple is formed by rolling plate and welding the seam. You can remove the weld flash from the outside or inside surfaces using a scarfing blade. The seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. In comparison with other pipes, the seamless steel pipe withstands pressure better actually.

The welded steel pipe may be cheaper than the seamless pipe actually. And the welded zone can be heat treated to make the seam less visible and dimensionable tolerances than seamless steel pipe. Frankly speaking, the main difference between them can be seen from their names. Seamless steel pipe is extruded and drawn from a billet while welded pipe is produced from a strip that is roll formed and welded to produce a pipe. However, the welded pipe is cheaper than seamless pipe.
