Flange DN50

Maybe you don’t know. That the flange dimensions are not the same as in other materials. For each standard, and each pressure class, the size of the flange is also different. DN50 flange example.

In JIS 5K, its OD is 130, but in JIS 10K, the OD is 155. Although the same pressure standard, the size is different.

Advantages and applications of flange DN50

Flange DN50 in particular and flanges in general have been and are important accessories in pipeline works.

They help the liquids and gases in the pipeline not to leak. The connection between the pipe segments with each other and with other fittings is tighter.

Re-installation is extremely easy, just weld the pipe and bolt to fix it. Especially in large pipes that are difficult to connect using threaded fittings.

As for DN50 flanges, you can find them in these works:

  • Gas pipelines
  • Oil pipelines
  • Water pipeline
  • On pressure vessels, boilers, …
