Pipe
A pipe is a tubular section or hollow cylinder used mainly to carry substances which can flow, usually liquids and gases (fluids). Pipe is also often used in structural applications as a hollow pipe is far stiffer than a solid piece of the same weight.
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. These NPS standards can be a bit confusing, so we have created a reference to help.
