Bend and Elbows

A BEND is the generic term for what is called in piping as an “offset” – a change in direction of the piping. Bends are usually custom-made (using a bending machine) on site and suited for a specific need.

An ELBOW is a specific, standard, engineered bend pre-fabricated as a spool piece and designed to either be screwed, flanged, or welded to the piping it is associated with. An elbow can be 45 degree or 90 degree. There can also be custom-designed elbows, although most are catagorized as either “short radius” or long radius”.


Couplings are short lengths of pipe used to connect 2 joints of tubing or casing. They come with painted color codes on their external surface to indicate their grades. Sizes available range from OD: 2-3/8’’ to 20″
