Applications and Benefit

Applications of Flange DN80

Depending on the design, the Application and Benefit of the theme may be different.


  • The blind flanges are used to seal the end of the pipeline.
  • The internally threaded flange is mainly used to reduce the pipe size
  • Flanges with weld necks are mainly used for high-pressure equipment.

and many more uses.
