Maintenance and upkeep are crucial for ensuring the safety of low-temperature storage tanks. Here are some common maintenance measures:
Regular Inspections: Conduct regular checks on low-temperature storage tanks, including inspections of the exterior, internal structure, and anti-corrosion coatings. Check for cracks, corrosion, wear, and other issues, and promptly identify and repair potential safety hazards.
Cleaning and De-icing: Regularly clean the exterior surface and internal structure of the low-temperature storage tank to remove accumulated dirt and ice layers. The buildup of ice can lead to structural damage and corrosion; cleaning and de-icing can extend the lifespan of the tank.
Level Monitoring: Regularly monitor the liquid level of low-temperature storage tanks to ensure it remains within a safe range. Excessive or low levels can lead to overpressure or over-vacuum in the tank, increasing safety risks.
Leak Detection: Install a leak detection system to regularly check for leaks in low-temperature storage tanks. Leaks can lead to the release and evaporation of liquids or gases, increasing safety risks.
Corrosion Prevention Measures: Implement appropriate corrosion prevention measures such as coating protection and corrosion-resistant coatings to safeguard the metallic structure of low-temperature storage tanks from corrosion.
Emergency Fault Handling: Establish an emergency fault handling mechanism to promptly address and repair issues with low-temperature storage tanks to prevent accidents from occurring or escalating.
Training and Development of Personnel: Train and develop operators and maintenance staff to ensure they possess the relevant knowledge and skills for the correct operation and maintenance of low-temperature storage tanks.
It's important to note that maintenance should be tailored to the specific type of tank and operating conditions, adhering to relevant local laws, regulations, and standards. During the maintenance process, it is advisable to consult with engineers or guidance from relevant institutions to ensure the tank's safety and reliability.

When selecting the pedestal for a liquid argon tank, several factors should be considered:
Load Capacity: The support must be capable of bearing the weight of the liquid argon tank. Select a support with adequate load capacity based on the tank's capacity and dimensions. Typically, the weight of the liquid argon tank is specified in the design specifications, which can be used to determine the support's load capacity.
Stability: The support must provide adequate stability to prevent any tilting or swaying of the tank during use. The design of the support should take into account the center of gravity of the tank and its changes, to ensure stable support.
Corrosion Resistance: Liquid argon has low temperatures and corrosive properties. The support material should possess excellent corrosion resistance to prevent corrosion and damage. Common support materials include stainless steel and aluminum alloys.
Insulation: Liquid argon storage tanks typically require thermal insulation, with the supports being equipped with certain insulating properties to reduce heat transfer and the evaporation of liquid argon. The design of the supports should take into account the installation and protection of the insulating layer.
Installation and Maintenance: The support should feature ease of installation and maintenance, facilitating the tank's installation and daily maintenance operations.
When selecting the supports for liquid argon tanks, it's advisable to consult with engineers or suppliers. Choose the appropriate supports based on the specific tank requirements and usage environment. Additionally, adhere to relevant design specifications and safety standards to ensure the quality and reliability of the supports.
