Loosing Flanged 22.5° Bend  is commonly used in piping systems to change the direction of flow while maintaining a specific angle, in this case, 22.5 degrees.

Here are some details about loose flanged bends:

Key Characteristics:

1. Angle: The 22.5° angle allows for a gradual change in direction, which can help reduce turbulence and pressure loss in the system.

2. Loose Flanges: Unlike welded flanges, loose flanges can be attached and detached easily. This feature is useful for maintenance and repairs since it allows for easier disassembly.

3.Material: These bends can be made from various materials such as carbon steel, stainless steel, or other alloys, depending on the application and the fluids being transported.

4. Applications: Commonly used in industries such as oil and gas, water treatment, chemical processing, and HVAC systems.

5. Installation: Proper installation is crucial to ensure a leak-free and efficient piping system. Gaskets are often used between flanges to create a tight seal.
