Cryogenic tank manufacturer for the temperatures others won't touch
Cryogenic storage is the most engineering-intensive part of any oil-gas, fertiliser or petrochemical plant. The inner shell sees -33 ×C to -196 ×C; the outer shell takes mechanical and atmospheric loads; perlite or foam-glass insulation must stay dry, settle predictably and survive 25 years of thermal cycling. Get any of these wrong and the tank either leaks, ices or fails fitness-for-service inspection. As a specialist cryogenic tank manufacturer, HAIL takes single-point responsibility for design, fabrication, erection, insulation, helium leak test, cool-down and commissioning of cryogenic tanks across India.
Cryogenic services we deliver
Ammonia tanks (-33 ×C)
Single-containment and double-containment ammonia tanks for fertiliser plants and refrigerated terminals. Carbon steel inner with cold-stretched roof.
LPG tanks (-42 ×C)
Refrigerated LPG storage for import terminals and LPG bottling plants. LTCS inner shell, complete BOG handling.
LOX & LIN (-183 / -196 ×C)
Liquid oxygen and liquid nitrogen storage for steel plants, hospitals and air-separation units. SS 304/304L inner with perlite insulation.
Ethylene (-104 ×C)
Ethylene and propylene cryogenic storage for cracker plants and downstream petrochemical units.
Insulation systems
Expanded perlite, foam-glass, polyurethane foam (PUF) and resilient blanket — selected for thermal performance, settling control and replacement strategy.
Cryogenic auxiliaries
BOG compressors, vaporisers, ambient and steam-heated vaporisers, cold pumps, cool-down piping and instrumentation.

Frequently asked questions
What products require cryogenic storage?
Ammonia (-33 ×C), LPG (-42 ×C), LOX (-183 ×C), LIN (-196 ×C), ethylene (-104 ×C), butene, propylene and LNG (-162 ×C). Each requires specific metallurgy and insulation.
Which codes does HAIL design to?
API 620 Appendix Q/R, BS 7777, EN 14620 and IS 16071. Welding qualified to ASME Section IX.
What insulation systems do you use?
Expanded perlite, foam-glass, polyurethane and resilient blanket — chosen for temperature, settling and replacement strategy.
Do you handle refrigeration and BOG too?
Yes — turnkey scope includes BOG compressors, vaporisers and instrumentation.
Can you build LNG tanks?
For LNG (9% Ni or membrane), we work with consortium partners including RINA Consulting for design assurance.
