Application of Flange DN100

For large-diameter flanges like this. Their main application is in pipeline works. Specifically:

  • Oil pipeline
  • Gas pipeline
  • Water pipeline

Some applications of flanges

Flange DN100 can be used both between pipe segments, between valve and pipe segment, or end of the pipeline.


Aim to link separate pipe segments together and link with industrial valves to regulate the flow in the pipe
