Cryogenic Liquid Oxygen (LOX) Vessels
Cryogenic liquid oxygen (LOX) vessels are specialized pressure containers designed to store and transport liquid oxygen at its boiling point of -297°F (-183°C). These vessels require meticulous oxygen-clean fabrication practices and compatible materials to ensure safe operation with this highly reactive cryogenic oxidizer.
Why are Cryogenic Liquid Oxygen (LOX) Vessels Needed?
Liquid oxygen vessels are critical for industries requiring reliable oxygen supply for combustion, medical, and industrial applications. LOX provides the most economical method of storing and transporting large quantities of oxygen, with one gallon of liquid expanding to over 860 cubic feet of gas at standard conditions.
Cryogenic Liquid Oxygen (LOX) Vessels Applications
Common applications include:
- Steel and metal production
- Medical and hospital oxygen supply
- Wastewater treatment
- Glass and ceramics manufacturing
- Chemical oxidation processes
- Aerospace propulsion systems

Cryogenic Liquid Oxygen (LOX) Vessels Frequently Asked Questions (FAQs)
What special requirements apply to oxygen vessel fabrication?
Oxygen vessels require oxygen-clean fabrication per CGA G-4.1 standards. This includes thorough cleaning to remove all hydrocarbons and contaminants, use of oxygen-compatible materials and lubricants, and stringent cleanliness verification. All components in contact with oxygen must be designed for oxygen service.
What materials are approved for liquid oxygen service?
Approved inner vessel materials include 304/304L and 316/316L stainless steel, which maintain excellent impact properties at cryogenic temperatures and are compatible with liquid oxygen. Aluminum alloys are also used for specific applications. All gaskets, seals, and lubricants must be oxygen-compatible.
How do you prevent oxygen enrichment hazards?
Our LOX vessels incorporate design features to prevent oxygen enrichment in the vacuum annulus including molecular sieve adsorbents, proper venting systems, and leak detection provisions. Operational procedures and safety training materials address oxygen enrichment hazards and proper handling practices.
