Cryogenic testing

CEWAC performs this test mainly on valves. This kind of test determines the valve’s ability to maintain its pressure while immersed in a liquid nitrogen bath. (-196 °C) or placed in a climatic room (-155°C).

The measured parameters are the tightness of the valve body and seats as well as its controllability after the exposure time.

Capacité du banc d'essai :

  • Maximum testing pressure: 1200 bar (liquid and gas).
  • Maximum valve dimension: 8".
  • Helium leak detector: smallest detectable leak rate in sniffing mode is < 5x10-8 mbar l/s??

Standards : BS 6364 – SHELL - QATARGAS
