Liquid Nitrogen Storage Vessels – Before & After

The importance of a good vacuum in the annulus of a pressure vessel cannot be overstated although it is quite difficult to spot when there is a problem.

A loss of vacuum can be very small and caused by a leak through the evacuation port O-rings, vacuum burst disc or deterioration caused by out-gassing in the vacuum inter-space.

This may not be seen directly as cold, wet or ice on the exterior of the vessel, but your evaporation rate as increased along with your liquid nitrogen bill!

How do we service Liquid Nitrogen storage vessels?

We will carry out a full inspection and service of your storage vessel including re-evacuation to <10-4mbar, Helium leak detection, burst disc repairs and exterior cleaning. The service is then complemented with a comprehensive report detailing before and after vacuum pressure levels and all work completed.
