PRV RIG Capacities

Our workshop has a pressure relief valve rig with a hydraulic clamping device suitable for the following flange sizes (or their metric equivalents):

  • 1 1/2″ to 14″ ASA 150
  • 1 1/2″ to 8″ ASA 300
  • 1 1/2″ to 6″ ASA 600
  • 1 1/2″ to 3″ ASA 1500IMG_0369

Note we can adapt the rig to take flanges smaller that 1 1/2″.

In addition to the above we also:

  • Bubble test flanges complete with joining and clamps.
  • A special adapter flange for use with rig to enable screwed valves to be tested.

Our rig also comes with a gas control module complete with:

  • Four test gauges, which are protected gauge protectors to eliminate damage by over testing.
  • Direct connections to the test rig.
  • Additional connection for back pressure and bellows seal testing.

The module gauges range from 0 to 175 bar we can modify the rig with additional standard test gauges if a higher test pressure is required.
