How To Select GOST Flanges
How To Select GOST Flanges
  • Raw Material- They need to be of the best quality or the flanges will not be capable to perform and get deformed in severe conditions.
  • Pressure Rating- It is critical to test the pressure rating to understand if the given flanges will be capable to withstand the given nominal pressure.
  • Dimensional Accuracy- This would help in proper sealing.
GOST Blind Flanges Features
GOST Blind Flanges Features
  • Identical to those of a typical blind flanges
  • It aids in completing the pipe run and secures the pipe`s end connection.
  • They resemble flat steel plates that lack a central hub.
  • They have perimeter bolts, which offer a tight seal.
