Low Temperature Storage Tank 60 LNG
Classification：Cryogenic storage tank Low temperature storage tank is a vertical or horizontal double-layer vacuum insulated storage tank used to store liquid oxygen, nitrogen, argon, carbon dioxide and other media. The material of inner liner is austenitic stainless steel; the material of outer container is Q235-B, Q245R or 345r
Product Introduction
LNG storage tanks are designed for the safe containment of liquefied natural gas at -162°C, where advanced multi-layer construction ensures thermal stability, structural integrity, and zero-leak safety performance.
Inner Tank (Membrane / Primary Container)
The inner tank is the core pressure-retaining and liquid-holding structure.
Materials:
Low-temperature steel
Nickel steel
Stainless steel
Aluminum alloys
Titanium (corrosion-resistant applications)
Function:
Direct contact with cryogenic LNG
Ensures liquid-tight sealing
Maintains toughness at ultra-low temperatures
Prevents brittle fracture under cryogenic stress
Insulation System
A critical thermal barrier layer between inner and outer structures.
Materials:
Rigid polyurethane foam
Phenolic foam
Foam glass
Perlite insulation
Function:
Minimizes heat transfer into LNG
Reduces evaporation (boil-off gas loss)
Stabilizes temperature gradients
Protects inner tank from thermal expansion stress
Outer Tank (Secondary Structure / Can Body)
The outer tank provides full structural protection and load-bearing support.
Materials:
Carbon steel (Q235-B, Q245R, 345R)
Reinforced concrete
Prestressed concrete
Function:
Structural load support
External impact and environmental protection
Secondary containment barrier
Thermal and mechanical stability
Outer Tank Construction Types
Steel Outer Tank
Used for above-ground systems
Requires environmental protection and insulation control
Reinforced Concrete Wall
Common for underground installations
