The spacing regulations between liquid oxygen storage tanks are typically governed by relevant safety standards and specifications to ensure safe distances and fire separations between the tanks. Below is a reference to general spacing rules for liquid oxygen storage tanks:
Horizontal spacing between tanks: The horizontal spacing between liquid oxygen tanks is typically required to maintain a certain distance to prevent heat conduction and mutual interference between tanks. The specific spacing should be determined based on factors such as tank capacity, pressure, and arrangement, with a general recommendation to maintain a safe distance to ensure safe operation and maintenance between tanks.
Tank and building or facility spacing: The spacing between liquid oxygen tanks and buildings, or other facilities, must also meet relevant safety requirements. This is to prevent any danger to surrounding buildings or facilities in the event of a tank leak or accident. Specific spacing requirements will be determined based on the tank's capacity, pressure, and surrounding environment, among other factors. Generally, it is recommended to maintain a certain safety distance.
Fire Protection Distance: It is crucial to maintain sufficient fire protection distances between liquid oxygen tanks and between tanks and buildings. Liquid oxygen contains a high concentration of oxygen and is highly flammable. In the event of a leak or accident, it could ignite a fire. Therefore, liquid oxygen tanks must maintain a certain distance from other facilities to ensure that a fire does not spread or pose a danger to the surrounding environment.
It's important to note that specific liquid oxygen tank spacing regulations may vary by region or industry. When designing, arranging, and operating liquid oxygen tanks, adhere to local safety standards and regulations, and consult with experts for accurate guidance.

The liquid nitrogen tank boasts the following features during the construction process:
Low-Temperature Construction: The construction of liquid nitrogen tanks must be carried out in low-temperature conditions, as the boiling point of liquid nitrogen is low, approximately -196 degrees Celsius. Construction personnel must take appropriate protective measures, such as wearing thermal protective clothing and gloves, to protect themselves from low-temperature injuries.
Welding Technology: Extensive welding is required during the manufacturing process of liquid nitrogen tanks, including the connection of tank walls, bottom plates, top plates, and seams. Welding technology is crucial for the quality and safety of the tank, necessitating the use of appropriate welding methods and materials to ensure the strength and sealing integrity of the welds.
Insulation Layer Installation: Liquid nitrogen storage tanks must have excellent insulation properties to reduce heat conduction and maintain the low temperature state of liquid nitrogen. The installation of the insulation layer requires materials such as polyester foam and glass wool, ensuring the thickness and quality of the insulation layer.
Proper installation steps for liquid nitrogen tanks are as follows:
Site Preparation: Select a suitable site for tank installation, ensuring it is level, sturdy, and has adequate load-bearing capacity. The site should be kept away from flammable, explosive materials, and other hazardous sources.
Foundation Construction: Construction of the foundation based on the tank's dimensions and weight, including excavation of the foundation pit and casting of concrete foundation. The design and construction of the foundation must comply with relevant standards and specifications.
Tank Installation: Transport the tank to the site and perform vertical installation. Appropriate lifting equipment and safety measures must be used during the installation process to ensure the stability and safety of the tank.
Pipe Connections: As required, connect the storage tank to the relevant pipeline system, including intake pipes, exhaust pipes, and liquid supply pipes, etc. Sealing and testing are necessary during the connection process to ensure the safety of the pipes.

The safe operation of low-temperature liquid storage tanks primarily involves the following key aspects:
Tank design and material selection: The tank design must comply with relevant safety standards and regulations, capable of withstanding the pressure and temperature of low-temperature liquids. Select suitable materials such as stainless steel, aluminum alloy, etc., to ensure the tank's corrosion resistance and low-temperature performance.
Insulation and Protection Measures: Low-temperature liquid storage tanks should be equipped with effective insulation to reduce heat transfer and evaporation of the liquid. The selection and installation of the insulation should comply with relevant standards and requirements. Additionally, protective measures such as anti-freezing and explosion-proof measures should be implemented to ensure the safe operation of the tank.
Pressure Control and Safety Valves: Low-temperature liquid storage tanks should be equipped with reliable pressure control systems and safety valves to ensure that the pressure inside the tank remains within a safe range. The pressure control system should be capable of promptly detecting and adjusting the pressure inside the tank to prevent risks from excessively high or low pressure.
Leak and Fire Protection: Low-temperature liquids are highly flammable, so measures should be taken to prevent leaks and fires. Tanks and related pipelines must have good sealing and regular inspections and maintenance to prevent leaks. Additionally, appropriate fire protection equipment and firefighting tools should be provided to address fire risks.
Safety Operation and Training: Operators must undergo relevant safety training, familiarize themselves with the safety operation procedures and emergency response measures for low-temperature liquid storage tanks. Adhere to the correct operational steps to ensure safe operation.
Regular inspections and

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 considerations. - Safety Inspections: Conduct necessary safety checks before operating the liquid oxygen storage tank, including inspecting the tank's integrity, the tightness of valves and pipes, and the condition of the insulation layer. - Liquid Oxygen Supply: Ensure the liquid oxygen supply system is functioning properly, including checking the status of the supply pipes, valves, and pressure gauges to ensure an adequate supply of liquid oxygen. - Tank Pressure Control: Monitor the pressure in the liquid oxygen storage tank to ensure it remains within safe limits. If necessary, control the tank's pressure by adjusting pressure valves or pressure relief devices. - Leak Control: Regularly inspect the tightness of the tank and pipes to ensure there are no leaks. In case of a leak, take immediate measures to control it and notify relevant personnel. - Fire Prevention Measures: Prohibit open flames and prevent sparks and hot objects from contacting the storage tank around it. Establish fire prevention facilities and firefighting 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 pipes 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, adhering to 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, cooperation with local regulatory agencies and personnel should be sought to ensure the tank's safety and reliability.
