Test Facilities for Cryogenic Service
- Assemble the valve that completed cold emulsion treatment and install it to the flanges for enabling the test. Input and output port shall be made on the flanges in advance.
- Submerge the valves installed to the flanges into the vessel of liquified Nitrogen Gas with the vertical arrangement for cryogenic status.
- Allow enough time for the submerged valves until the temperature of valve reaches to -196°C.
- Under the cryogenic status, inject the nitrogen or helium gas into the flanges at the applicalbe pressure.
- Measure the leaked volume of nitrogen or helium gas from the seat area for the duration of one minute. Measured leak volume shall be decided for acceptance or non-acceptance in accordance with the criteria to BS 6364, that is, 200mm/sXDN(12ccXDN).
