The materials used in the construction of liquid oxygen tanks typically need to possess excellent low-temperature resistance and corrosion resistance. The following are common materials used for liquid oxygen tank construction:
Stainless Steel: Stainless steel is a common material used in the construction of liquid oxygen tanks, known for its excellent corrosion resistance and mechanical strength. Common stainless steel grades include 304 and 316.
Aluminum Alloy: Aluminum alloys are also commonly used in the production of liquid oxygen tanks, featuring low density and excellent corrosion resistance. Common aluminum alloy materials include 5083 and 6061 alloys.
Fiberglass Reinforced Plastic (FRP): Fiberglass is a composite material composed of glass fibers and resin. It boasts excellent corrosion resistance and mechanical strength, making it suitable for liquid oxygen storage tanks in some specialized environments.
Carbon Steel: Carbon steel is a common material for tank fabrication, known for its high strength and corrosion resistance. However, it is prone to oxidation in liquid oxygen environments, necessitating anti-corrosion measures.
It's important to note that the choice of materials for liquid oxygen tanks should be determined based on specific application requirements, working conditions, and safety standards. When selecting materials, consider the properties of liquid oxygen and the design requirements of the tank to ensure safety and reliability. Additionally, manufacturers and suppliers often provide material selection advice and technical support.

Liquid Oxygen Storage Tanks are specialized equipment that requires particular attention to safety and understanding of their characteristics when in use. Below are the safety precautions and features of using liquid oxygen storage tanks: **Safety Precautions:** - **Operation:** The operation of liquid oxygen storage tanks should be performed by trained and experienced personnel. Operators should be familiar with the tank's structure, performance, and operational procedures, and operate strictly according to the manual and safety regulations. - **Fire Prevention Measures:** Liquid oxygen is highly oxidizing and can easily cause fires and explosions. Open flames and sparks should be prohibited around the storage tank, and high-temperature objects should be kept away. Fire prevention facilities and fire-fighting equipment should be established, and regular inspections and maintenance should be conducted. - **Leakage Control:** In the event of a leakage, immediate measures should be taken to control the leak. Leaks can lead to the evaporation of liquid oxygen and an increase in oxygen concentration, increasing the risk of fire and explosion. A leak detection system should be set up, along with leakage control devices and personal protective equipment. - **Insulation Protection:** Liquid oxygen storage tanks should have good insulation to reduce evaporation and maintain low temperatures. The insulation should be regularly inspected and maintained to ensure its integrity and insulating performance. - **Safety Distance:** A certain safety distance should be maintained around the storage tank to prevent the spread of fires, explosions, and leaks. The specific safety distance requirements should be assessed and determined according to local regulations and standards. **Features:** - **High Oxidizing Properties:** Liquid oxygen has high oxidizing properties, which can support and intensify combustion. Therefore, particular attention to fire and explosion prevention measures is required when using liquid oxygen storage tanks. - **High Pressure Storage:** Liquid oxygen storage tanks typically store high-pressure oxygen, with pressures usually around 2-5 bar. Therefore, pressure control and the safety of pressure relief devices should be noted during the operation and maintenance of liquid oxygen storage tanks. - **Low Temperature Storage:** The liquid oxygen in the storage tank is at a low temperature, usually around -183°C. Therefore, when contacting the liquid oxygen storage tank, appropriate protective measures should be taken.

The use and operation of the liquid oxygen storage tank system require attention to the following points:
Safe Operation: When operating the liquid oxygen storage tank system, it is mandatory to adhere to the relevant safety operating procedures and standards to ensure the safety of the operators.
Tank Selection: Choose liquid oxygen tanks that comply with regulations and standards, ensuring their quality and safety performance.
Tank Installation: Tanks should be installed on a solid foundation to ensure stability. Additionally, good ventilation should be maintained around the tank, and it should be kept away from flammable materials and heat sources.
Seal Integrity Check: Regularly inspect the storage tank system's sealing performance to ensure there are no leaks at valve and pipeline connections.
Pressure Control: The tank system should be equipped with a pressure gauge and a safety valve, with regular inspections and maintenance to ensure pressure remains within a safe range.
Fire Prevention Measures: Liquid oxygen has a high oxygen content, which is highly flammable. Set up firewalls around the storage tank system, prohibit smoking and open flames, and ensure safety.
Electrostatic Protection: During the operation of the liquid oxygen system, static electricity can cause sparks, increasing the risk of fire. Measures such as using electrostatic conductive materials and anti-static equipment are taken to reduce the accumulation and release of static electricity.
Regular inspections and maintenance: Conduct regular checks of the storage tank system and related equipment, including valves, pipes, pressure gauges, etc. Ensure that the equipment is in good condition without damage, and promptly repair or replace any damaged parts.
Waste Gas Treatment: During the operation of the liquid oxygen system, waste gas is produced, and appropriate waste gas treatment measures must be implemented to minimize environmental impact.
Above are the precautions to be noted when using the liquid oxygen storage tank system, ensuring operational safety and the normal operation of the system. During operation, it should be strictly adhered to the relevant operational procedures and safety operation requirements to avoid accidents.
