Cryogenic Maintenance, Repair & Spare Parts Suppliers

Maintenance, repair, and spare parts suppliers keep cryogenic equipment operating through its full service life. Cryogenic equipment is high-value, long-lifetime, and often specialized โ€” planned maintenance and access to authentic spares directly determines availability, safety, and total cost of ownership. This category covers OEM after-sales service, independent service organizations, spare parts distributors, and specialty repair shops.

Service categories in this listing include vacuum re-evacuation for stationary and mobile vacuum-jacketed vessels, cryogenic pump overhaul and rotating assembly exchange, valve repair and cryogenic re-qualification, compressor major inspection, brazed aluminum heat exchanger repair and modification, tank internal inspection and repair, refurbishment of end-of-life tanks and ISO containers to extend service, MLI replacement and vessel re-insulation, and OEM and OEM-alternative spare parts supply.

This directory lists cryogenic MRO suppliers worldwide. Each supplier profile covers service scope, OEM authorization status for specific equipment lines, in-shop versus field-service capability, geographic presence, response time for emergency service, code authorization for repair work (National Board R-stamp, PED conformity assessment for repairs), and spare parts stocking policy.

Owners evaluating MRO suppliers typically weigh OEM authorization for warranty-sensitive equipment, mean time to repair (MTTR) for critical assets, availability of long-lead spare parts on the shelf, code authorization for pressure vessel repair work, technical documentation quality, and long-term service agreement options that align maintenance with production requirements. Filter suppliers by country, equipment type, or service.

Frequently asked questions

Can vacuum insulation be restored on old tanks?

Yes. Most vacuum-jacketed tanks can be re-evacuated to restore original insulation performance. Re-evacuation removes accumulated gases from the annular space through a service valve, followed by getter regeneration or replacement. Turnaround is typically 2 to 6 weeks for mobile equipment and 1 to 4 weeks in situ for stationary tanks.

What is an R-stamp?

A certification from the National Board of Boiler and Pressure Vessel Inspectors authorizing a company to perform repairs and alterations to pressure vessels covered by the ASME BPVC. R-stamp is required for any code-related repair on ASME-stamped cryogenic tanks in the US. Similar authorizations exist under PED (notified body involvement).

How often should cryogenic pumps be overhauled?

Interval depends on pump type and duty. Centrifugal pumps in industrial gas service typically go 3 to 5 years between major overhauls. Reciprocating pumps for hydrogen refueling and cylinder filling may need overhaul every 4,000 to 8,000 operating hours. Suppliers publish recommended intervals based on service.

Are OEM spare parts required?

Not always by contract, but strongly recommended for pressure-containing parts and rotating equipment. OEM-alternative parts may be acceptable for consumables (packing, gaskets, filters). For code-stamped vessels, any replacement part in a pressure boundary must meet the original material specification and be documented in the vessel record book.

How do service agreements work?

Long-term service agreements bundle scheduled maintenance, spare parts, and often guaranteed response time under a single contract with monthly or quarterly fees. They provide predictable maintenance cost and priority technician availability. Terms range from 3 to 10 years and often include performance guarantees on equipment availability.
