The liquid oxygen storage tank has the following characteristics:
High Purity: The liquid oxygen storage tank contains high purity liquid oxygen, typically exceeding 99.5% purity. This makes the liquid oxygen tank essential in applications requiring high purity oxygen, such as medical, industrial, and research fields.
Low Temperature: Since the boiling point of liquid oxygen is -183°C, the liquid oxygen storage tank must have excellent insulation properties to maintain its low temperature. Tanks are typically designed with double or multi-layer structures, filled with insulating material in between to minimize heat transfer and evaporation of the liquid oxygen.
High Pressure: Liquid oxygen tanks typically need to withstand high pressure to maintain their liquid state. The design and material selection of the tank must consider the pressure requirements of liquid oxygen to ensure the tank's safety and reliability.
Flammability: Liquid oxygen is highly flammable and can support combustion. Therefore, during the design and use of liquid oxygen storage tanks, fire prevention measures must be implemented to ensure there are no ignition sources nearby, and appropriate fire extinguishing equipment is provided.
High Density: Liquid oxygen has a higher density compared to gaseous oxygen, allowing liquid oxygen tanks to store more oxygen. This makes liquid oxygen tanks advantageous for applications requiring large amounts of oxygen supply, such as in the field of...
Corrosiveness: Liquid oxygen possesses certain levels of

Standard specifications for liquid oxygen storage tanks may vary by region. Here are examples of some common standards: - U.S. Standards: The American National Standards Institute (ANSI) and the American Petroleum Institute (API) have issued a series of standards for liquid oxygen storage tanks, such as ANSI/API Standard 2510 "Design and Construction of Liquid Oxygen Storage Tanks" and ANSI/API Standard 2510A "Supplement to the Design and Construction of Liquid Oxygen Storage Tanks." - European Standards: The European Committee for Standardization (CEN) has issued a series of standards for liquid oxygen storage tanks, including EN 13458 "Liquid Oxygen Storage Tanks. Design and Manufacturing" and EN 14015 "Vertical Welded Steel Fixed Storage Tanks. Design and Manufacturing." - Chinese Standards: The China National Committee for Standardization (SAC) has issued a series of standards for liquid oxygen storage tanks, such as GB/T 18442 "Design Code for Liquid Oxygen Storage Tanks" and GB/T 18443 "Construction and Acceptance Code for Liquid Oxygen Storage Tanks." These standards typically cover requirements for design, manufacturing, installation, operation, maintenance, and inspection of liquid oxygen storage tanks. They encompass provisions for the tank's structure, materials, safety valves, insulation layers, leak control, fire protection measures, and safety distances to ensure the safety and reliability of the storage tanks. When designing, manufacturing, and using liquid oxygen storage tanks, it is essential to follow applicable standards and regulations, and to cooperate with local regulatory authorities and personnel to ensure compliance with relevant safety requirements and regulations.

The manufacturing process for the heads and cylinders of low-temperature storage tanks typically includes the following steps:
Material Preparation: Select suitable materials, such as low-temperature alloy steel or stainless steel, based on design requirements and specifications. Inspect and verify the materials to ensure their quality meets the standards.
Sheet cutting: Sheets are cut to specified dimensions and shapes. Common cutting methods include flame cutting, plasma cutting, or laser cutting, among others.
Bending and Shaping: Cut sheets are bent and shaped to form heads and cylinders. Common shaping methods include cold bending, hot bending, or hydraulic forming, etc.
Welding: Welds the shaped plates together to form the structure of the head and cylinder. Common welding methods include manual arc welding, gas shielded welding, or laser welding, etc.
Weld Seam Treatment: Process the weld seams after welding, such as sanding, polishing, or applying anti-corrosion coatings, to enhance the quality and appearance of the welds.
Inspection and Acceptance: Conduct inspections and acceptance of the finished heads and cylinders to ensure quality and compliance with design specifications. Common inspection methods include ultrasonic testing, X-ray inspection, or liquid penetrant testing, etc.
Strengthening and Support: As required, perform processing and installation of reinforcing and supporting on the head and cylinder to enhance the structural strength and stability.
Surface Treatment: The heads and cylinders are treated for surface finish, such as applying anti-corrosion coatings, hot-dip galvanizing, or polishing, to enhance their corrosion resistance and aesthetic quality.
It is important to note that the manufacturing process of low-temperature storage tanks must comply with relevant standards and regulations to ensure the quality and safety of the production process. During manufacturing, strict adherence to safety operating procedures and the implementation of necessary protective measures are required to ensure the safety of the operators.
