TECHNICAL FAQs
About Liquid Oxygen Tanks
LOX storage tanks are available in various capacities ranging from small medical oxygen systems to large industrial bulk storage tanks. Custom capacities can be engineered according to project requirements.
Most LOX tanks feature a stainless steel inner vessel (304 or 316L) for cryogenic service and a carbon steel outer shell with protective coating for durability and corrosion resistance.
Vacuum insulation combined with multilayer insulation significantly reduces heat ingress, resulting in lower boil-off rates, improved storage efficiency, and longer holding times.
LOX tanks typically include pressure relief valves, burst discs, oxygen-compatible piping systems, pressure monitoring devices, and emergency safety controls to ensure safe operation.
Depending on project requirements, LOX tanks can be designed and manufactured according to ASME, CE/PED, EN13458, TPED, and other applicable international standards.
Yes. Tank capacity, design pressure, operating pressure, orientation (vertical or horizontal), instrumentation, and piping configurations can be customized to suit specific applications.
LOX tanks typically undergo hydrostatic testing, helium leak testing, vacuum integrity testing, non-destructive testing (NDT), and quality inspections before shipment.
Yes. Complete LOX storage systems can be supplied with ambient air vaporizers, pressure-building systems, regulators, instrumentation, and control panels as required by the application.
