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 connections, and perform leak detection and pressure testing, etc. Detect and repair potential issues promptly to ensure the normal operation of the tank.
Maintain Insulation Layer: The insulation layer is crucial for the thermal insulation of liquid argon tanks. Regularly inspect the integrity and insulation performance of the insulation layer, repair or replace damaged insulation materials to ensure the tank's insulation effectiveness.
Regulate liquid argon temperature: The temperature of liquid argon should be maintained within an appropriate range to prevent damage to the storage tank from excessive or insufficient temperatures. Employ suitable cooling or heating measures to ensure stable temperature control 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 it remains intact.
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 cracking 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 contaminants 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 documents, including tank usage, inspection logs, 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 performing maintenance and operation, please adhere to relevant regulations and standards, and consult with experts to ensure safety and effectiveness.

The stable pressure design of a 15 cubic meter liquid argon storage tank should take into account the following aspects:
Tank Pressure: Determine the design pressure of the tank to meet the storage and supply requirements for liquid argon. Establish an appropriate design pressure range based on the characteristics and usage conditions of liquid argon.
Pressure Regulation System: Select an appropriate pressure regulation system to maintain stable pressure within the storage tank. The pressure regulation system typically includes components such as pressure regulators, pressure sensors, and control valves, which are used for monitoring and adjusting the pressure inside the tank.
Pressure Sensor: Install a pressure sensor to monitor the pressure changes within the storage tank in real-time. The sensor transmits pressure signals to the pressure regulation system to promptly adjust the control valve's opening, maintaining the stable pressure inside the tank.
Control Valves: Select an appropriate control valve for regulating gas flow and pressure within the storage tank. The control valve should have excellent regulating performance and stability to ensure the pressure within the tank remains within the set range.
Safety Valve: Install a safety valve to automatically release gas when the pressure inside the storage tank exceeds the set value, preventing overpressure. The safety valve should be selected and installed based on the design pressure and capacity of the storage tank.
Voltage Stabilization System Control: Configure an appropriate control system to monitor and manage the operation of the voltage stabilization system. The control system enables automatic adjustment and alarm functions to ensure stable and safe pressure within the storage tank.
It is important to note that the design of the pressure-stabilizing system should be tailored to the specific engineering requirements and operating conditions of the liquid argon storage tank, adhering to relevant local regulations, standards, and specifications. When designing and installing the pressure-stabilizing system, it is recommended to consult with experienced engineers or relevant institutions to ensure the reliability and safety of the system.

A 50 cubic meter liquid oxygen tank refers to a storage tank with a capacity of 50 cubic meters. Liquid oxygen tanks are commonly used for storing and supplying liquid oxygen, for applications such as research, experiments, and more.
