Safety usage and transportation of liquid oxygen tanks should be mindful of the following points:
Safe Application Methods:
Tank Selection: Choose liquid oxygen tanks that meet specifications 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 Inspection: Regularly inspect the storage tank's sealing performance to ensure there are no leaks at valve and pipeline connections.
Pressure Control: Tanks should be equipped with pressure gauges and safety valves, and undergo regular inspections and maintenance to ensure pressure remains within safe limits.
Fire Prevention Measures: Liquid oxygen contains a high concentration of oxygen, which is highly flammable. Set up fire barriers around the storage tanks, prohibit smoking and open flames, and ensure safety.
Static protection: During the transportation and use of liquid oxygen, static electricity can 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.
Shipping Precautions:
Transportation Vehicle Selection: Choose transportation vehicles that meet the requirements for liquid oxygen transport, ensuring their safety and sealing.
Loading and Unloading: During the transportation of liquid oxygen, appropriate loading and unloading procedures should be adopted.

To safely utilize liquid oxygen tanks, attention should be paid to the following aspects:
Training: Personnel handling liquid oxygen tanks must undergo training to understand the properties of liquid oxygen, safety operating procedures, and emergency response measures. Only trained personnel are authorized to operate liquid oxygen tanks.
Safety Operating Procedures: Establish and adhere to the safety operating procedures for liquid oxygen tanks, including proper operational procedures, protective measures, and emergency response plans. Ensure operators follow the procedures to minimize accident risks.
Equipment Inspection and Maintenance: Regularly inspect the status of liquid oxygen storage tanks and related equipment, including valves, pipelines, pressure gauges, etc. Ensure the equipment is in perfect condition, and promptly repair or replace any damaged parts.
Leak Control: Equipped with leak detection and alarm systems to promptly identify and control leaks in liquid oxygen storage tanks. Upon detection of a leak, immediate measures should be taken to contain the source and initiate repairs.
Fire Prevention Measures: Liquid oxygen has a high oxygen content, which is prone to causing fires. Measures such as setting up fire barriers around liquid oxygen storage tanks and using fire-resistant coatings are taken to prevent the occurrence and spread of fires.
Static Protection: The accumulation of static electricity in liquid oxygen tanks 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.
Ventilation Requirements: Ensure adequate ventilation within the enclosed space of the liquid oxygen storage tank to expel gases produced by the evaporation of liquid oxygen. Avoid excessive oxygen concentration to minimize

Liquid oxygen storage tanks may deform during use. The following are common deformation defects in liquid oxygen storage tanks:
Elastic Deformation: Liquid oxygen tanks may experience elastic deformation when subjected to external pressure or temperature changes. This deformation is typically reversible, meaning the tank will return to its original shape upon the removal of external pressure or the normalization of temperature.
Plastic Deformation: When a liquid oxygen tank is subjected to significant external force or pressure, it may experience plastic deformation. This deformation is irreversible, and the tank cannot return to its original shape. Plastic deformation can cause changes in the tank's shape, such as dents or warping.
Hot Deformation: Liquid oxygen storage tanks may experience hot deformation when subjected to high temperatures or temperature changes. Hot deformation can cause the tank to change shape, expand, or contract.
Cold Deformation: Liquid oxygen tanks may experience cold deformation when subjected to low temperatures or temperature changes. Cold deformation can cause the tank to change shape, shrink, or crack.
These deformation defects may affect the structural integrity and safety of liquid oxygen storage tanks. Therefore, it is important to regularly inspect and assess the deformation of liquid oxygen storage tanks to ensure their normal operation and safe use. If deformation defects are found in the tanks, prompt repair or replacement measures should be taken to avoid further damage and safety risks.

To extend the service life of liquid argon storage tanks, the following measures can be taken:
Regular inspections and maintenance: Conduct periodic visual inspections, valve and connection checks, and leak detection and pressure testing on liquid argon storage tanks. Promptly identify and repair potential issues to ensure the normal operation of the tanks.
Maintain Insulation: The insulation layer is crucial for the thermal preservation of liquid argon tanks. Regularly inspect the integrity and insulating performance of the insulation, repair or replace any damaged insulation materials to ensure the tank's insulating effectiveness.
Control Liquid Argon Temperature: Maintain the liquid argon temperature within an appropriate range to prevent damage to the storage tank from excessive or low temperatures. Implement suitable cooling or heating measures to ensure stable liquid argon temperature.
Corrosion Protection: The exterior shell and internal structure of the liquid argon tank should be protected against corrosion and oxidation. Regular inspections and maintenance of the protective coating are required to ensure its integrity.
Avoid excessive pressure and overfilling: Prevent the internal pressure of the tank from being too high or too low, as well as overfilling with liquid argon. Excessive pressure and overfilling can lead to structural rupture or damage to the tank.
Regular cleaning and waste removal: Regularly clean the interior of the tank to remove accumulated impurities and dirt. Regularly remove waste to prevent impurities and sediments in liquid argon from damaging the tank.
Safety Operations and Training: Ensure operators are knowledgeable and skilled in the safe operation of liquid argon tanks. Enhance safety training to boost operators' awareness and emergency response capabilities.
Establish comprehensive management records and documentation, including tank usage, inspection, and maintenance records. Regularly review and update these records to ensure the safe management and maintenance of the tanks.
These measures can help extend the service life of liquid argon storage tanks, but specific operations and management are required based on the type and application of the tank. When performing maintenance and operation, please adhere to relevant regulations and standards, and consult with experts to ensure safety and effectiveness.
