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.

The laboratory can also performed low fugitive emissions and desing validation testing.

Limits of the test bench :

  • Maximum testing pressure: 300 bar (gas).
  • Maximum weight of the valve : 2 tons

Standards :

- Cryogenic/low temperature : BS 6364 – SHELL

- Low fugitive emissions : ISO 15848-1

- Design validation testing according to Shell specification MESC SPE 77/300
