A 180 degree short radius elbow is a pipe fitting that is used to connect two pipes at an angle of 180 degrees. The short radius elbow has a smaller radius of curvature than the long radius elbow, which means it is more compact and has a tighter turning radius. This fitting is typically made of carbon steel, stainless steel, or other metals and is used in various industries such as oil and gas, petrochemicals, and power generation. Its main purpose is to change the direction of the pipeline and to prevent fluid flow from being obstructed.
