The standard Butt-Weld elbows come in three basic radius’s 90°, 45°, and 180°. When requesting an elbow, the default standard is the “Long Radius” but they can also be supplied in “Short Radius”. The terms “Long Radius” and “Short Radius” are important to understand. “Long Radius” means that the centre to end dimension is one and a half times the nominal pipe size. “Short Radius” means that the centre to end dimension is equal to the nominal pipe size. A 180 degree return bend is not commonly stocked, and generally needs to be produced per request.
