If the threaded pipe flange can be precisely measured, the following information is required:

  • O: Outside Diameter of flange
  • C: Thickness of flange
  • R: Diameter of raised face
  • X: Hub Diameter at base
  • Y: Length through hub
  • T: Minimum thread length
  • Q: Minimum diameter of bolt circle

The threaded flange is screwed to the threaded pipe by the thread that is processed in the flange's inner hole. As a result, it does not need to be welded. As a result, it is much easier to install and maintain when compared to other flange types such as slip on flanges, socket weld flanges, and so on.

Raised Face Threaded Flange

Raised Face Threaded Flange

The raised face flange is easily identified when the gasket surface area is above the flange's bolted line. It works with a wide range of gaskets, from flat to semi-metallic and metallic, ring or full.

When metal to metal seals are required, the ring joint flange has a circular groove to accommodate the ring joint gasket. Especially in high-pressure and high-temperature conditions.

  • Threaded flanges can be fitted to pipes of various sizes without the need for welding, which is one of the main reasons why these flanges are so popular.
  • They can be used in extremely high pressure applications, especially at or near atmospheric temperatures, where post-weld heat treatment is not possible.
  • They are ideal for piping with small diameters.
  • They are cost-effective and time-saving devices.
  • Threaded flanges are typically used in non-cyclic applications.
