Operation procedures for liquid oxygen storage tanks should be established based on specific tank design and usage requirements. The following are some common contents of general operation procedures for liquid oxygen storage tanks: - Operator Training: Ensure operators have received relevant training for liquid oxygen storage tanks, understanding the tank's structure, performance, operation procedures, and safety precautions. - Safety Inspections: Conduct necessary safety checks before operating the liquid oxygen storage tank, including checking the tank's integrity, the sealing of valves and pipelines, and the condition of the insulation layer. - Liquid Oxygen Supply: Ensure the liquid oxygen supply system is functioning properly, including inspecting the status of liquid oxygen supply pipelines, valves, and pressure gauges, and ensuring an adequate supply of liquid oxygen. - Tank Pressure Control: Monitor the pressure of the liquid oxygen storage tank to ensure it remains within a safe range. If necessary, control the tank's pressure by adjusting pressure valves or pressure relief devices. - Leak Control: Regularly check the sealing of the tank and pipelines to ensure there are no leaks. In case of a leak, take immediate measures for leak control and notify relevant personnel. - Fire Prevention Measures: Prohibit open flames and prevent sparks and high-temperature objects from contacting the tank around the liquid oxygen storage tank. Establish fire prevention facilities and fire extinguishing equipment, and conduct regular inspections and maintenance. - Safety Distance: Maintain a certain safety distance around the liquid oxygen storage tank to prevent the spread of fires, explosions, and leaks. - Maintenance and Repair: Regularly perform maintenance and repairs on the tank, including cleaning the tank, inspecting the insulation layer, valves, and pipeline conditions, to ensure the tank operates normally. - Waste Disposal: Properly dispose of waste generated by the liquid oxygen storage tank, including liquid oxygen residues, waste gases, and waste liquids, following relevant environmental protection regulations and standards. Note that operation procedures for liquid oxygen storage tanks should be established based on specific tank design and usage requirements and should comply with applicable regulations, standards, and safety guidelines. When operating liquid oxygen storage tanks, cooperate with local regulatory agencies and individuals to ensure the tank's safety and reliability.

The materials used for making liquid oxygen storage tanks typically need to possess excellent low-temperature resistance and corrosion resistance. The following are common materials for manufacturing liquid oxygen storage tanks:
Stainless Steel: A commonly used material for liquid oxygen storage tanks, stainless steel boasts 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 made of glass fibers and resin. It boasts excellent corrosion resistance and mechanical strength, making it suitable for liquid oxygen storage tanks in special environments.
Carbon Steel: Carbon steel is a common material for making tanks, 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 storage tanks should be determined based on specific application requirements, operating environment, 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 recommendations and technical support.

Maintenance and upkeep are crucial for ensuring the safety of low-temperature storage tanks. Here are some common maintenance measures:
Regular Inspections: Conduct regular checks on low-temperature storage tanks, including inspections of the exterior, internal structure, and anti-corrosion coatings. Check for cracks, corrosion, wear, and other issues, and promptly identify and repair potential safety hazards.
Cleaning and De-icing: Regularly clean the exterior surface and internal structure of low-temperature tanks to remove accumulated dirt and ice layers. The buildup of ice can lead to structural damage and corrosion; cleaning and de-icing can extend the lifespan of the tank.
Level Monitoring: Regularly monitor the liquid level in low-temperature storage tanks to ensure it remains within a safe range. Excessive or low levels can lead to overpressure or over-vacuum in the tank, increasing safety risks.
Leak Detection: Install a leak detection system to regularly inspect for leaks in low-temperature storage tanks. Leaks can cause the release and evaporation of liquids or gases, increasing safety risks.
Corrosion Protection Measures: Implement appropriate corrosion protection measures, such as coating protection and corrosion-resistant coatings, to safeguard the metallic structure of low-temperature storage tanks from corrosion damage.
Emergency Fault Handling: Establish an emergency fault handling mechanism to promptly address and repair issues with low-temperature storage tanks, preventing accidents from occurring or escalating.
Training and Development of Personnel: Train and develop operation and maintenance personnel to ensure they possess relevant knowledge and skills for the proper operation and maintenance of low-temperature storage tanks.
Note that maintenance should be tailored to the specific type of tank and operating conditions, adhering to relevant local laws, regulations, and standards. During maintenance, it is recommended to consult with engineers or guidance from relevant institutions to ensure the tank's safety and reliability.
