Buttweld Pipe Fittings, ASTM B366 UNS N08810 Incoloy Alloy 800H 180Deg. Return Bend
A 180-degree return bend is a type of pipe fitting that allows for a complete directional change in a piping system, effectively returning the flow back in the opposite direction. The bend typically features a smooth curve, minimizing flow resistance and turbulence.

There are several types of elbows used in piping systems, including:
1. 45-degree elbow: This type of elbow changes the direction of flow by 45 degrees.
2. 90-degree elbow: This type of elbow changes the direction of flow by 90 degrees.
3. 180-degree elbow: This type of elbow changes the direction of flow by 180 degrees, effectively reversing the direction of flow.
4. Short radius elbow: This type of elbow has a shorter center-to-end distance than a standard elbow, making it ideal for use in tight spaces.
5. Long radius elbow: This type of elbow has a longer center-to-end distance than a standard elbow, which helps to reduce friction and pressure loss in the system.
Applications
They are commonly used in industrial piping systems where redirection of flow is necessary, such as:
