Butt Weld Fittings

180 Degree Elbow

A 180-degree elbow, also known as a "Buttweld 180° Elbow" (BW) or "180° Bend," is a pipe fitting that changes the direction of a piping system by 180 degrees. This means the pipe effectively reverses direction at the elbow, creating a straight run of pipe but with a change in orientation.
Key Features:

Function: Used to reverse the direction of fluid flow in a piping system.
Material: Typically made of steel (carbon, stainless, or alloy), and can be seamless or welded.
Types: Exists in both Long Radius (LR) and Short Radius (SR) versions, with LR elbows generally offering smoother flow and less friction.
Applications: Used in various industries like wastewater treatment, chemical plants, and power generation, where reversing the direction of a pipe run is necessary.
Standards: Commonly manufactured to standards like ASME B16.9.
