Inspection of self-pressurizing liquid nitrogen vessels
The High Pressure Gas Safety Act necessitates inspection of self-pressurizing vessels for liquid nitrogen. Check and confirm the stamped month/year of the previous inspection on the production plate. If the vessels require inspection, proceed with the inspection.
Filling of the vessels overdue for inspection with liquid nitrogen is prohibited.
Consult Liquefaction Division of the Cryogenic Reserch Center or your local supplier to proceed with the inspection. For more detail please see the followings.
