Cryogenic Storage Tanks

Cryogenic storage tanks must safely contain liquefied gases at extremely low temperatures while minimizing heat ingress and product losses. Roben Manufacturing engineers custom dual-walled cryogenic vessels featuring vacuum-insulated construction for superior thermal performance. Our tanks are designed for liquid nitrogen, liquid oxygen, liquid argon, LNG, and other cryogenic applications, with materials selected for reliable service at temperatures down to -320°F (-196°C) and below.

Application Importance

Cryogenic storage presents unique engineering challenges including extreme temperature differentials, thermal contraction stresses, and the need for exceptional insulation performance. Dual-walled vacuum-insulated construction provides the thermal protection required to minimize boil-off and maintain product quality. Material selection must prevent brittle fracture at cryogenic temperatures while accommodating thermal cycling. Roben Manufacturing delivers cryogenic tanks meeting all applicable requirements while optimizing thermal performance for specific applications.

Frequently Asked Questions

What insulation systems are available for cryogenic tanks?

We offer vacuum with perlite insulation for standard applications and vacuum with multi-layer insulation (MLI) for demanding applications requiring minimal heat leak. Insulation system selection is based on required boil-off rates, duty cycle, and economic considerations.

How are inner vessels supported within the outer jacket?

Inner vessels are supported using low-conductivity support systems designed to minimize heat transfer while accommodating thermal contraction. Support designs vary based on vessel size, orientation, and seismic requirements.

What testing is performed on cryogenic vessels?

All cryogenic vessels undergo hydrostatic testing, vacuum leak testing, and impact testing of materials and welds. Vacuum performance is verified, and complete documentation of all testing is provided.
