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 liquid argon tanks, check valves and fittings, and perform leak detection and pressure testing. Promptly identify and repair potential issues to ensure the normal operation of the tanks.
Maintain the 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 thermal insulation 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 outer 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 over-filling: Prevent excessive internal pressure or low pressure within the storage tank, as well as over-filling with liquid argon. Excessive pressure and over-filling may lead to structural cracking or damage to the tank.
Regular Cleaning and Drainage: Regularly clean the interior of the tank to remove accumulated impurities and dirt. Regularly drain to prevent contaminants and sediments in the 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' safety 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 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 follow relevant regulations and standards, and consult experts to ensure safety and effectiveness.

In the degreasing process of high-vacuum pipelines in low-temperature liquid storage tanks, the following steps can be taken:
Preparation: Ensure the cleanliness and readiness of the defatting equipment and tools. Check the piping system's connections and seals to ensure there are no leaks.
Pipe Cleaning: Utilize suitable cleaning agents and tools to clean the pipes, removing surface dirt and grease. Methods may include mechanical brushing, high-pressure water jetting, or chemical cleaning.
De-greasing Process: Select an appropriate de-greaser and inject it into the pipeline system. The de-greaser can be an organic solvent or an alkaline solution, the choice depending on the pipeline material and type of dirt. Ensure the de-greaser thoroughly covers the inner pipeline wall and maintains a certain contact time.
Flush Pipeline: Drain the degreaser from the pipeline system and flush with clean water to remove any remaining degreaser and dirt. During the flushing process, high-pressure water or gas can be used for scrubbing to ensure the cleanliness of the pipeline interior.
Drying Pipeline: Utilize drying equipment or ventilation systems to evaporate or exhaust moisture within the pipeline, ensuring the inner wall remains dry. Drying can be achieved using hot air or nitrogen.
Inspection and Testing: After degreasing, inspect and test the pipeline to ensure cleanliness and sealing. Visual inspection, pressure testing, or other relevant tests can be conducted.
Be mindful that when descaling high vacuum pipelines of low-temperature liquid storage tanks, adhere to the relevant safety operating procedures and guidelines. Ensure that operators possess the necessary safety awareness and operational skills to prevent accidents.

Proper management regulations for the use of low-temperature liquid storage tanks encompass the following aspects:
Tank Selection and Installation: Choose an appropriate low-temperature liquid storage tank and ensure it complies with relevant standards and regulations. The installation of the tank should be carried out by personnel and operated according to 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, venting, and other operational steps. Operators must receive training to understand the characteristics of liquid storage tanks, safety precautions, and emergency response measures.
Safety Equipment and Protective Measures: Tanks should be equipped with necessary safety devices, such as pressure sensors, safety valves, leak detectors, etc., to monitor and control the pressure and temperature of the tank. At the same time, operators should wear appropriate personal protective equipment, such as insulated gloves, protective suits, etc., to ensure their own safety.
Regular Inspections and Maintenance: Conduct regular checks and maintenance on low-temperature liquid storage tanks, including inspecting the tank's appearance, seals, and corrosion protection. 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. Residual liquids in abandoned tanks should be properly handled to prevent environmental pollution.
Tank Records and Tracking: Establish a tank usage record, including filling dates, filling quantities, usage status, etc. Additionally, it is recommended to implement a tank tracking system for monitoring and managing the usage and maintenance of the tanks.
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, comply with relevant laws and standards and establish appropriate management measures based on the actual situation.
