Manufacturer of Mitered Pipe Bends | ASME/ANSI B16.9, ANSI B16.28, MSS-SP-43
A mitered pipe bend is a type of pipe bend where the pipe is cut into multiple segments at a specific angle and then welded together to form a bend. Unlike traditional curved pipe bends, mitered bends allow for sharp directional changes in the pipeline, often used when space constraints or design requirements demand an angular change rather than a smooth curve. These bends are typically used when precise directional changes are necessary and where the space or radius available is limited.
Mitered bends are important because they allow engineers to achieve the required pipe direction without the need for large-radius bends, which can take up more space and material. Additionally, they are often more cost-effective and faster to manufacture compared to standard bends, making them a popular choice in tight or intricate piping systems. They are commonly used in industries such as oil and gas, chemical processing, power generation, and construction, where tight routing and flexibility are crucial. While mitered bends may not be as smooth as regular curved bends, their ability to save space and reduce costs makes them an essential option in many pipeline systems.

Mitered bends provide a more compact design compared to standard bends and can be used in applications where space constraints are a concern. They allow for sharper turns in the piping system, helping to optimize layout and flow.
The standard angles for mitered pipe bends are 30°, 45°, 60°, and 90°. However, custom angles can be designed to suit specific project requirements.
A mitered pipe bend consists of multiple segments welded together to form an angle, while a long-radius bend is a continuous curve with a specified radius. Mitered bends are more cost-effective for sharp changes in direction but may cause more turbulence in fluid flow compared to smooth-radius bends.
