Repairs, Refurbishment, Recertification & Revalidation

Did you know that Wessington Cryogenics are able to offer repair / refurbishment facilities which will enable virtually all types of cryogenic storage vessel to be returned to an 'As New' condition?

These facilities include :-
  • A detailed examination of the vessel to determine the full extent of the repair work required. This includes a helium leak test and a visual check on all valves and safeties by our engineers.
  • A fully equipped workshop which allows us to carry out both external and internal repairs to virtually all types of cryogenic vessels (excluding aluminium vessels with fibre glass necks).
  • A team of engineers experienced in the field of cryogenic vessel manufacture can rebuild even the most badly damaged vessel. Modifications to existing equipment are also available
  • Highly qualified welders approved, among others, by Bureau Veritas and Lloyds, to European & ASME regulations allow for the highest integrity weld repairs to be carried out.
  • Vacuum pumping facilities allow for all vessels to be heated and hard pumped for maximum service life
  • Helium mass spectrometer leak test to detect even the tiniest of leaks
  • Experienced fitters can completely rework, rebuild and replace existing pipework, valves and safeties to ensure the vessel performs in a safe and efficient manner
  • Pressure test facilities which allow us to examine your vessel in accordance with the Pressure Systems Safety Regulations

Wessington can also repair & recertify your ISO Frame tanks.

ISO Pack 2000 Tank Following Refurbishment.


These repairs include :-

  • Five yearly compliance check
  • Documentation, certification and Third Party survey
  • Inspection & recalibration of tank gauges
  • Relief valves inspected, recalibrated (or replaced) and tagged
  • Vacuum check & full vacuum service
  • Helium leak test
  • Lift test in accordance with BS 7072
  • Frame repairs - from single member to complete frame replacement
  • Tank & frame blast & repaint
  • New decals



Please contact the Sales Department to discuss the repair of your ISO tank. A 'Returns Number' is required prior to sending your tank for examination, together with a purchase order to cover initial inspection, detailed report & handling costs. This cost is offset against main vessel repair costs.
All documentation is required to be supplied with the tank at time of initial delivery. Failure to supply all necessary paperwork can significantly affect the repair process of your tank, and ultimately may lead to the tank being unable to be re-certified. Storage fees may be applicable if we are unable to action your repair due to non supply of documentation
