Liquid Oxygen Storage Tanks
Liquid Oxygen Storage Tanks
Introduction: The Essential Role of Liquid Oxygen Storage
Liquid oxygen (LOX) is a crucial resource across numerous industries, from healthcare to manufacturing and aerospace. Its storage and transportation require specialized equipment designed for safety, efficiency, and reliability. This document provides an overview of our advanced liquid oxygen storage tanks, highlighting their design features, applications, and operational advantages.
Tank Design and Construction
Our liquid oxygen storage tanks are engineered with a robust double-walled, cylindrical design. The inner vessel and piping are constructed from high-grade S30408 stainless steel, ensuring compatibility with the cryogenic temperatures of liquid oxygen and preventing corrosion. The outer shell is made from Q245R alloy steel, providing structural integrity and protection.
Insulation: The annular space between the inner and outer vessels is filled with expanded perlite (pearl sand), a highly effective insulation material. In addition, a specially treated adsorbent is installed to remove any residual moisture or gases, contributing to a high vacuum environment (ranging from 0.5 to 6 Pascals). This dual-layer insulation approach minimizes heat transfer and reduces boil-off losses.
Capacity: Our standard tank capacities range up to 200 m³, allowing for both small-scale and large-scale storage needs. We also accommodate custom orders for specific capacity requirements.
Pressure Ratings: The tanks are designed to operate under high working pressures, with our dual-tank systems in four workshops operating at 2.0 MPa.
Vaporization System: An external vaporizer is integrated with each tank, facilitating both convenient filling and the direct delivery of pressurized gaseous oxygen.
Types and Applications
Our liquid oxygen storage tanks are available in two main configurations:
Stationary Tanks: Designed for fixed installations at production facilities, utilization points, or cryogenic fluid supply stations, offering a reliable and centralized storage solution.
Transport Tanks: These are engineered for the safe and efficient transportation of liquid oxygen, often via land or water. These include tank trucks, trailers, and tanker vessels, providing flexibility in supply chains.
Installation options include both vertical (L) and horizontal (W) configurations to best suit your spatial requirements and operational needs.

Broad Applications Across Industries
Our cryogenic storage tanks support critical applications across a range of sectors:
Metallurgical Industry: High-purity oxygen is used in steelmaking to reduce carbon content and remove impurities like phosphorus and sulfur. It also provides the necessary heat for the process, leading to faster and higher-quality steel production. Additionally, oxygen enrichment in blast furnaces reduces coke consumption and boosts metal yield. In non-ferrous metal production, oxygen accelerates smelting and increases output.
Chemical Industry: Oxygen plays a key role in synthetic ammonia production by oxidizing raw gases, facilitating processes like heavy oil thermal cracking and coal dust gasification, enhancing efficiency and fertilizer production.
Defense Industry: Liquid oxygen is an essential oxidizer for modern rockets and supersonic aircraft. It's also used to produce liquid oxygen-based explosives for its high explosive potential.
Healthcare: Oxygen is administered in hypoxic conditions, such as during diving, mountain climbing, high-altitude flights, space missions, and medical procedures, addressing breathing difficulties.
Manufacturing Process: Ensuring Quality and Precision
Volume and Drawing Finalization: Custom designs are created based on the requirements and needs of our clients.
Material Preparation and Cutting: Precise material selection and cutting for accurate assembly.
Steel Rolling: Forming steel plates into cylindrical shapes.
Steel Plate Welding: Skillfully joining steel plates to form tank shells.
Storage Tank Assembly: Combining components into a final tank assembly.
Insulation Filling: Filling the gap between inner and outer vessels with insulating material.
Vacuum Creation: Establishing a high vacuum for optimal insulation.
RT and MT Inspection: Conducting rigorous X-ray inspections to ensure weld integrity.
Tank Rust Removal: Preparing the surface for protective coating.
Valve Installation: Installing all necessary valves and fittings.
Technical Advantages: Ensuring Performance and Safety
Adiabatic Performance: The combination of perlite sand insulation, a high vacuum, and superior filling processes ensures outstanding insulation performance. Surface anti-corrosion treatment includes sandblasting, rust removal, and the application of a two-component, fast-drying liquid coating.
Safety Features: Our storage tanks are equipped with a "combined safety system" featuring two sets of safety valves working simultaneously. One can be closed for inspections while the other continues to function, ensuring uninterrupted and safe operations.
Monitoring Systems: Gauges, level meters, and level comparison charts at the top of each tank allow for constant monitoring of the liquid level and pressure changes, facilitating easy filling and emptying.
Control System: Vacuum meters and valves at the bottom of each tank allow for regular testing of the vacuum level, ensuring safe operation.
