The temperature difference between the interior and exterior of a low-temperature liquid storage tank depends on various factors, including the tank's design, insulation performance, the temperature of the liquid, and the ambient temperature. Generally, the temperature inside a low-temperature liquid storage tank is much lower than the ambient temperature.
Low-temperature liquid storage tanks are commonly used for storing cryogenic liquids such as liquid nitrogen, liquid oxygen, and liquid argon. These liquids have very low boiling points, usually below -100 degrees Celsius. To maintain the低温 state of the liquids, the internal insulation of the tank must be excellent to minimize heat transfer and evaporation loss.
Low-temperature liquid storage tanks typically offer a smaller temperature variance. Generally, the internal temperature of the tank can be maintained near the boiling point of the liquid, usually several dozen degrees lower than the ambient temperature. The specific temperature variance depends on the tank's design and insulation properties, as well as the characteristics of the liquid.
It's important to note that the temperature differences in low-temperature liquid storage tanks may vary over time. As time goes by, the insulating material's performance may be affected by wear or aging, leading to increased temperature differences. Therefore, regular inspections and maintenance of the tank's insulation are crucial to ensure its effective and stable insulating performance.

Oxygen storage tanks and liquid oxygen storage tanks are devices used for storing oxygen, but they have some distinctions: Storage form: Oxygen storage tanks are typically used for storing gaseous oxygen, while liquid oxygen storage tanks are used for storing liquid oxygen. Oxygen is in a gaseous state at room temperature but is cooled to a liquid state at low temperatures for more efficient storage and use. Storage pressure: Oxygen storage tanks usually store high-pressure oxygen, with pressures around 200-300 bar. Liquid oxygen storage tanks store liquid oxygen at lower pressures, generally around 2-5 bar. Storage capacity: Oxygen storage tanks usually have smaller capacities, suitable for personal or small-scale use. Liquid oxygen storage tanks have larger capacities, suitable for industrial or large-scale applications. Storage method: Oxygen storage tanks store oxygen in a gaseous form, via compressed gas storage. Liquid oxygen storage tanks store oxygen as a liquid, converting it to a liquid state by cooling it to temperatures below its boiling point. Safety requirements: Due to the high oxidizing nature of liquid oxygen, liquid oxygen storage tanks require stricter safety standards in design and use. Liquid oxygen storage tanks typically need to have good thermal insulation, leak control, and fire prevention measures to ensure safe operation. It is important to note that the specific design and specifications of oxygen storage tanks and liquid oxygen storage tanks may vary depending on different regions and application sites. When using these tanks, it is necessary to follow applicable regulations, standards, and safety guidelines, and to cooperate with local regulatory authorities and personnel to ensure the safety and reliability of the tanks.

During the operation of low-temperature liquid storage tanks, the following points should be noted:
Protective Gear: When handling low-temperature liquid storage tanks, appropriate protective gear must be worn, including gloves, protective clothing, and non-slip shoes. This gear helps protect the skin from the harm of low-temperature liquids.
Avoid direct contact: The low temperature of liquid can cause coldness. Therefore, avoid direct contact with low-temperature liquids, especially with the skin. Use tools or implements for handling to prevent direct hand contact with low-temperature liquids.
Ventilation Requirements: In the operational area of low-temperature liquid storage tanks, adequate ventilation must be ensured to expel gases produced by the evaporation of low-temperature liquids. Maintain air circulation to avoid excessive oxygen concentration, and reduce the risk of fire and explosion.
Prevent Leaks: Regularly inspect low-temperature liquid storage tanks for leaks, and equip with leak detection and alarm systems. In case of a leak, take immediate action to control and repair it. Avoid harm to personnel and the environment caused by the leakage of low-temperature liquids.
Fire prevention measures: Low-temperature liquids have low boiling and freezing points, which are prone to cause fires. To prevent and control fires, fire walls should be set up around low-temperature liquid storage tanks, and fire-retardant coatings should be used.
Static protection: Handling low-temperature liquids may generate static electricity, increasing the risk of sparks igniting fires. 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 condition of low-temperature liquid storage tanks and related equipment, including valves, pipes, pressure gauges, etc. Ensure that the equipment is in perfect condition without damage, and promptly repair or replace any damaged parts.
Waste Gas Treatment: During the process of using low-temperature liquids, waste gas is produced, which necessitates appropriate waste gas treatment measures to minimize environmental impact.
Above are the precautions to be noted when using low-temperature liquid storage tanks, ensuring operational safety and the normal operation of the tank. During operation, strictly follow the relevant operational procedures and safety operation requirements, avoid
