LNG Vacuum Storage Tank

• Function: Storage Cryogenic Liquid
• Type: Vertical or Horizontal
• Storage Medium: LNG Liquid Natural Gas

1. The design, manufacturing and inspection of vacuum storage tank mainly according to GB/T18442.1~6-2019 "Static vacuum insulated cryogenic pressure vessel", and can also follow international standards such as ASME. 
2. The inner vessel is used to store liquid natural gas, and the shell material is austenitic stainless steel, which has good low temperature resistance. The outer shell plays a protective role and provides reliable protection for the interlayer insulation material and vacuum degree. 
3. The interlayer is insulated by vacuum powder, and the insulation material is made of perlite, which greatly reduces heat intrusion, reduces the evaporation rate of cryogenic liquid, and ensures long-term storage. 
4. The storage tank is equipped with stainless steel cryogenic globe valve, combined vacuum valve (including vacuum gauge to measure the vacuum degree of the insulation layer at any time), safety valve, relief device, pressure gauge, liquid level gauge and other valve instruments;
5. The inner vessel is equipped with two sets of independent over-pressure relief devices to effectively ensure the safety of the tank. In addition, the safety explosion-proof devices installed on the outer vessel further ensure the safety and reliability of the entire equipment. 
6. For the inner vessel of the storage tank, 100% Radiographic Testing (RT) is first performed on Category A and Category B welded joints. This is followed by 100% Penetrant Testing (PT) on all welded joints. After ensuring that the non-destructive testing results are qualified, a pneumatic test is conducted on the inner vessel. Finally, each weld and joint is subjected to a leak test using a helium mass spectrometer leak detector. 
7. The finished paint film on the outer surface of the storage tank is dense, firm and reliable, and the dry film thickness of the paint is greater than 200 µm. 
8. The tank needs to be replaced with nitrogen before leaving the factory. Fill the interior of the liquid container with 0.03~ 0.05Mpa pressure nitrogen gas for protection. 
9. The LNG vacuum storage tank is easy to install and have low maintenance costs. It is mainly used in city gas supply, industry combustion gas supply and gas station, etc.

Application

Residential Gas Supply

Used in remote areas or communities without pipeline natural gas infrastructure, where LNG is vaporized at gasification stations for household use.

Gas Boilers & Industrial Fuel

Provides clean energy for industrial boilers, drying equipment, and centralized gas supply systems, supporting coal-to-gas conversion initiatives.

Vehicle Refueling Stations

Serves as storage for LNG vehicle fuel, promoting green transportation.

Marine Fuel Supply

Stores LNG for ships, reducing maritime emissions and meeting environmental regulations.

Natural Gas Storage & Peak Regulation

Acts as an emergency reserve during high-demand periods or supply disruptions to ensure stable energy supply.

Satellite Liquefaction Units

Works with medium-sized tanks (50-100m³) for LNG storage in distributed energy systems.

 

Industrial Gas Vaporization Stations

Supplies efficient fuel for glass, ceramic, and metal processing industries.

Combined Power & Heat Pump Systems

Uses LNG as fuel for generators or fuel cells to improve energy efficiency.

Liquefaction Plants & Peak Shaving Stations

Provides temporary storage in LNG production processes, supporting peak-shaving liquefaction units.

Mobile Gas Supply Equipment

Such as skid-mounted vaporization stations for rapid deployment in temporary or emergency gas supply scenarios.
