Proper management regulations for the use of low-temperature liquid storage tanks include the following aspects:
Tank Selection and Installation: Choose an appropriate low-temperature liquid storage tank and ensure it complies with relevant standards and regulations. Installation of the tank should be carried out by personnel, following the manufacturer's instructions and requirements to ensure stability and safety.
Safety Operating Procedures: Establish and implement safety operating procedures for liquid storage tanks, including startup, shutdown, filling, and venting procedures. Operators must undergo training to understand the characteristics of liquid storage tanks, safety precautions, and emergency response measures.
Safety Equipment and Protection Measures: Tanks should be equipped with necessary safety devices, such as pressure sensors, safety valves, leak detectors, etc., to monitor and control the tank's pressure and temperature. Additionally, operators should wear appropriate personal protective equipment, like insulated gloves and protective suits, to ensure their safety.
Regular Inspections and Maintenance: Conduct regular inspections and maintenance of low-temperature liquid storage tanks, including checking the tank's appearance, sealing integrity, and corrosion protection measures. In case of any issues, promptly repair or replace the tank to ensure its proper operation and safety.
Waste Management: Abandoned low-temperature liquid storage tanks should be disposed of in accordance with relevant environmental protection regulations. The residual liquids in the abandoned tanks should be handled properly to prevent environmental pollution.
Tank Record and Tracking: Establish tank usage records, including filling dates, quantities, and usage status. Additionally, it is recommended to set up a tank tracking system for monitoring and managing tank usage and maintenance.
Above are some common management regulations for low-temperature liquid storage tanks, with specific regulations potentially varying by industry and region. When using low-temperature liquid storage tanks, relevant laws and standards should be adhered to, and appropriate management measures should be established based on the actual situation.

The use and operation of the liquid oxygen storage tank system should be mindful of the following points:
Safe Operation: When operating the liquid oxygen storage tank system, it is mandatory to adhere to the relevant safety operation 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 around the tank is required, and it should be kept away from flammable materials and heat sources.
Seal Integrity Inspection: Regularly inspect the tank system's sealing performance to ensure there are no leakage issues at valve and pipeline connections.
Pressure Control: The storage tank system should be equipped with a pressure gauge and a safety valve, with regular inspections and maintenance to ensure the pressure remains within safe limits.
Fire Prevention Measures: Liquid oxygen contains a high oxygen content and is highly flammable. Install firewalls around the storage tank system, prohibit smoking and open flames, and ensure safety.
Static Protection: During the operation of the liquid oxygen system, static electricity may cause sparks, increasing the risk of fire. Measures such as using static-conductive materials and anti-static equipment are taken to reduce the accumulation and release of static electricity.
Regular Inspections and Maintenance: Conduct regular checks on the tank system and related equipment, including valves, pipes, pressure gauges, etc. Ensure that the equipment is in perfect condition 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 taken to minimize environmental impact.
Above are the precautions to be taken when using the liquid oxygen storage tank system, ensuring operational safety and the normal operation of the system. During operation, strict adherence to relevant operational procedures and safety requirements should be maintained to avoid accidents.

During the operation of low-temperature storage tanks, it is indeed necessary to avoid the occurrence of wrinkling. Wrinkling refers to the phenomenon where the tank walls develop creases or deformations, which may lead to a decrease in the structural integrity of the tank and could even cause leaks or ruptures.
Below are some precautions to avoid tank rolling in low-temperature storage:
Tank Design: Select an appropriate tank design that can withstand the pressure and weight of low-temperature liquids. The wall thickness and supporting structure of the tank should comply with relevant standards and regulations.
Material Selection: Choose materials suitable for low-temperature environments, with sufficient strength and low-temperature resistance. Common materials include low-temperature steel, stainless steel, etc.
Insulation Layer for Storage Tanks: The design and construction of the insulation layer must meet the requirements to ensure effective reduction of heat conduction and temperature variation. The material and thickness of the insulation layer should be selected based on the specific situation.
Tank Operation: During the liquid loading and unloading process, avoid rapid or excessive fluid flow to minimize impact and stress concentration on the tank walls.
Tank Maintenance: Regularly inspect and maintain the structure and insulation of the tanks to ensure they are intact. Any abnormalities or damages should be repaired or replaced promptly.
Temperature Control: During the operation of low-temperature liquid storage tanks, it is crucial to strictly control the temperature difference between the inside and outside of the tank to avoid excessive temperature changes and thermal stress.
In summary, preventing tank deformation due to low temperatures hinges on proper design, material selection, insulation installation and maintenance, as well as strictly controlling temperature variations. Regular inspections and maintenance are crucial for ensuring the safe operation of the tank.

To prevent the explosion of liquid oxygen tanks, the following measures can be taken:
Regular Inspections and Maintenance: Conduct regular inspections and maintenance on liquid oxygen tanks, including checking the tank's exterior, welds, valves, and fittings, to ensure they are intact and undamaged. Regularly clean the tank to remove any contaminants or dirt adhering to its surface.
Pressure Control: Storage tanks should be equipped with pressure control devices to ensure the internal pressure of the tank remains within a safe range. Regularly inspect and adjust the pressure control devices to ensure proper operation.
Temperature Control: The liquid oxygen tank should be maintained within an appropriate temperature range to avoid excessive heat causing an increase in pressure. Ensure the insulation layer of the tank is intact to minimize heat conduction and loss.
Fire Prevention Measures: Liquid oxygen has a high oxygen content and flammability, so strict fire prevention measures must be taken. A fire-resistant isolation area should be established around the storage tank, with smoking and open flames prohibited. Ensure that the storage tank maintains a proper fire-resistant distance from other facilities.
Pressure relief devices and safety valves: Liquid oxygen storage tanks should be equipped with pressure relief devices and safety valves to prevent overpressure and sudden pressure increases. Regularly inspect and test the operational status of the pressure relief devices and safety valves to ensure they are functioning properly.
Tank Operation Guidelines: Adhere strictly to the operational specifications and safety requirements for liquid oxygen tanks. Operators must be trained and familiar with the tank's characteristics and operating techniques. Avoid operational errors and violations.
Emergency Preparedness: Establish emergency response plans and conduct drills to address potential accidents. Train operators in emergency response capabilities to ensure timely and effective actions.
