Carbon Steel Pipe

Welded & Seamless Carbon Steel Pipe

A pipe is a tubular section or hollow cylinder used mainly to carry substances that can flow, usually liquids and gases (fluids). Commonly, the words tube and pipe are usually interchangeable, but they are actually different things. Pipe is used to convey liquids while tubing is used in structural applications. Pipe is generally divided into seamless pipe and welded pipe.  Welded pipe, sometimes called ERW (Electric Resistance Welded), is made by forming a flat piece of steel into a round shape and welding the edges together. Seamless pipe is made by drawing a solid piece of steel over a mandrel to create a solid tube without a weld seam.

Pipe size, for both seamless pipe and welded pipe, is most often stated as Nominal Pipe Size, defined by the NPS standard.

As a welded and seamless carbon steel pipe supplier, we sell many common types of pipe, including ERW and Seamless and black and galvanized.  End prep includes square, beveled, and plain.  We also have threaded and coupled material available.
