LNG Storage Tank Structural Design

Inner Cryogenic Pressure Vessel

Fabricated from high-grade 304/316L stainless steel or 9% nickel steel to retain fracture toughness and ductility at -162°C.

Outer Protective Shell

Heavy-duty carbon steel outer casing engineered to withstand vacuum pressure, external corrosion, and atmospheric environmental loads.

Perlite Vacuum Insulation

Expanded perlite under high vacuum environment for large-capacity economical thermal protection.

Internal Piping & Support System

Low-thermal-conductivity composite supports reduce thermal bridging between inner and outer shells while securing against transport shocks and seismic forces.

Applications

LNG Refueling Stations

Used as the primary LNG storage unit for vehicle fueling stations, providing reliable fuel supply for heavy-duty trucks, buses and commercial fleets.

LNG Satellite Stations

Suitable for areas without pipeline gas infrastructure, providing flexible LNG storage and supply solutions for remote industrial facilities, residential areas and distributed energy projects.

Industrial Gas Supply

Applied in factories, power plants and manufacturing facilities that require stable LNG storage for boilers, heating systems and industrial energy applications.

LNG Receiving Terminals & Distribution Centers

Used for LNG storage, transfer and regional distribution in small-scale LNG terminals and energy supply networks.
