To extend the service life of liquid argon storage tanks, the following measures can be taken:
Regular inspections and maintenance: Conduct regular visual inspections of the liquid argon tank, check valves and fittings, and perform leak detection and pressure testing, etc. Detect and repair potential issues promptly to ensure the normal operation of the tank.
Maintain Insulation: Insulation 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.
Regulate Liquid Argon Temperature: The temperature of liquid argon should be maintained within an appropriate range to prevent damage to the storage tank due to excessive or low temperatures. Implement suitable cooling or heating measures to ensure stable temperature of the liquid argon.
Corrosion Protection: The shell and internal structure of the liquid argon tank should be protected against corrosion and oxidation. Regularly inspect and maintain the protective coating to ensure its integrity.
Avoid excessive pressure and overfilling: Prevent the internal pressure of the tank from being too high or too low, and avoid overfilling with liquid argon. Excessive pressure and overfilling can lead to structural rupture or damage of 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 contaminants and sediments in liquid argon from damaging the tank.
Safe Operation and Training: Ensure operators are proficient in the safe operation of liquid argon tanks. Enhance safety training to boost operator awareness and emergency response capabilities.
Manage records and documents: Establish comprehensive management records and documents, including tank usage, inspection, and maintenance records. Regularly review and update these records to ensure 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 conducting maintenance and operation, follow relevant regulations and standards, and consult with experts to ensure safety and effectiveness.

To safely utilize liquid oxygen tanks, attention should be paid to the following aspects:
Training: Operators of 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 condition of liquid oxygen tanks and related equipment, including valves, pipes, pressure gauges, etc. Ensure that the equipment is in perfect condition without any damage, and promptly repair or replace any damaged parts.
Leakage Control: Equipped with leak detection and alarm systems to promptly identify and control leaks in liquid oxygen storage tanks. In the event of a leak, immediate measures should be taken to contain the source of the leak and initiate repairs.
Fire Prevention Measures: Liquid oxygen contains a high oxygen concentration, which is prone to causing fires. Measures such as setting up firewalls around liquid oxygen storage tanks and using fire-retardant coatings are taken to prevent fires from occurring and spreading.
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 and minimize

The installation of the safety valve in a liquid oxygen tank is a crucial component that ensures the tank can release pressure in the event of overpressure, protecting the tank and related equipment. The following are the steps for installing the safety valve in a liquid oxygen tank:
Determine the rated pressure of the safety valve: Select an appropriate safety valve based on the design pressure and flow requirements of the liquid oxygen storage tank. Ensure that the rated pressure of the safety valve meets the tank's specifications and complies with relevant safety standards and regulations.
Valve Installation Location: Select an appropriate location for the installation of the safety valve. Typically, the safety valve should be mounted at the top or side of the liquid oxygen storage tank to allow for timely pressure release in the event of overpressure.
Preparation for installation interfaces: Prepare the corresponding interfaces according to the connection method of the safety valve. This may include welding interfaces, threaded interfaces, or flange interfaces, etc. Ensure the sealing and firmness of the connections.
Install the safety valve: Mount the safety valve onto the prepared interface. Follow the installation instructions for the safety valve to ensure it is properly connected and tightened.
Adjustment and Testing: After installation, adjust and test according to the safety valve requirements. Ensure the opening and closing pressures of the safety valve meet the design specifications, and conduct a leakage test to ensure sealing.
Connect the exhaust pipe: The exhaust pipe of the safety valve should be properly connected to the outlet of the safety valve. The exhaust pipe should have sufficient diameter and flow capacity to ensure effective exhaust of overpressure gas when the safety valve opens.
Identification and Documentation: Label safety valves and discharge pipes with relevant information such as rated pressure, flow rate, and installation date. Additionally, record the installation details and test results of the safety valves for future reference and maintenance.
When installing the safety valve on the liquid oxygen storage tank, it is imperative to follow the relevant safety regulations and operation guidelines. If you lack the necessary experience and knowledge, it is recommended to seek assistance and guidance from experts to ensure the proper installation and reliable operation of the safety valve.
