The threaded Flange is a kind of non-welding Flange, which is made from the inner hole of the flange to pipe thread and connected with the pipe with thread.
Compared with the flat welding flange or Butt Welding Flange, the threaded flange has the characteristics of convenient installation and maintenance, and can be used in some pipelines where welding is not allowed. Alloy Steel Flange has sufficient strength, but not easy to weld, or welding performance is not good, can also choose threaded flange. However, it is not recommended to use threaded flanges to avoid leakage when the pipe temperature changes rapidly or the temperature is higher than 260 °C and lower than-45 °C.
