Liquid Nitrogen Storage Tanks

Advanced Liquid Nitrogen Storage Tanks: Ensuring Peak Performance and Safety Across Industries

Our liquid nitrogen storage tanks are meticulously engineered to provide reliable and secure cryogenic storage solutions, catering to a wide spectrum of industrial needs. These tanks are constructed with a focus on both performance and safety, ensuring the integrity of the stored liquid nitrogen. The foundation of our design is a robust, double-walled cylindrical structure, featuring an inner vessel and piping fabricated from high-grade S30408 stainless steel, known for its exceptional corrosion resistance and durability at cryogenic temperatures. This inner shell is housed within a resilient outer shell constructed from Q245R alloy steel, providing exceptional structural integrity.

The critical space between the inner and outer walls is carefully insulated with expanded perlite (pearl sand) and a specially treated adsorbent material, meticulously creating a high-vacuum environment typically ranging from 0.5 to 6 Pa. This advanced insulation system minimizes heat transfer, maintaining the cryogenic temperature of the liquid nitrogen and reducing evaporation. Our tanks are offered in a range of capacities, extending up to 200 cubic meters, and are designed to handle high pressures, with a standard working pressure of 2.0 MPa available across our production line of dual tanks across four workshops. An external vaporizer unit simplifies the filling process and facilitates the direct supply of pressurized gaseous nitrogen.

We understand that diverse applications require varied solutions. Therefore, our tanks are available in both stationary and transportable configurations. Stationary tanks, commonly installed at manufacturing facilities, points of use, or cryogenic liquid distribution hubs, are optimized for long-term, stable storage. Conversely, transportable options, including road tankers, trailers, and ship tankers, provide seamless and reliable transportation of cryogenic liquids from production sites to user facilities. These tanks are available in vertical (L) and horizontal (W) orientations, providing flexibility to integrate into various site layouts and operational needs.
