Cryogenic Storage Tank

Cryogenic liquid storage tanks are vacuum jacketed, powder-insulated pressure vessels specifically designed for the storage and supply of liquefied cryogenic gases such as:
Liquid Nitrogen (LIN)
Liquid Oxygen (LOX)
Liquid Argon (LAR)
Liquid Carbon Dioxide (LCO₂)

Typical capacities range from 3.5 m³ to 200 m³. These cryogenic tanks are widely used in industrial production, medical facilities, gas supply systems, and scientific research applications.

The cryogenic storage tank features a double-wall vacuum insulated design, available in both vertical and horizontal configurations.

The inner vessel is manufactured from high-quality austenitic stainless steel to ensure excellent low-temperature performance.
The outer vessel is constructed from carbon steel (Q235-B or Q345R), selected according to regional standards and regulatory requirements.
The annular space between the inner and outer vessels is filled with high-performance perlite insulation material and evacuated to high vacuum, providing superior thermal insulation and minimal heat leakage.

Material Advantages
Steel plates sourced from leading domestic steel manufacturers ensure stable and reliable raw material quality.
Optimized plate layout design reduces longitudinal and circumferential weld seams and minimizes head splicing welds.
Improved material utilization rate with reduced scrap, ensuring both cost efficiency and structural integrity.
Advanced submerged arc welding (SAW) wire and flux provide stable weld quality and excellent weld appearance.
Imported industrial coating system offers superior corrosion resistance, weather resistance, and attractive surface finish.
