When selecting the pedestal for a liquid argon tank, several factors should be considered:
Load Capacity: The support must be able to bear the weight of the liquid argon tank. Select a support with sufficient load capacity based on the tank's capacity and dimensions. Typically, the weight of the liquid argon tank is provided in the design specifications, which can be used to determine the load capacity of the support.
Stability: The support must provide sufficient stability to ensure the tank does not tilt or sway during operation. The design of the support should take into account the tank's center of gravity and its changes to provide stable support.
Corrosion Resistance: Liquid argon has low temperature and corrosive properties. The support material should have good corrosion resistance to prevent corrosion and damage. Common support materials include stainless steel, aluminum alloy, etc.
Insulation: Liquid argon storage tanks typically require thermal insulation. The supports should possess certain insulation 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 insulation layer.
Installation and Maintenance: The support should feature ease of installation and maintenance for convenient tank installation and routine maintenance tasks.
When selecting the support for liquid argon tanks, it's advisable to consult with engineers or suppliers. Choose the appropriate support based on the specific tank requirements and operating environment. Additionally, adhere to relevant design specifications and safety standards to ensure the quality and reliability of the support.

When using a 50-cubic-liter liquid oxygen storage tank, the following safety concerns should be noted:
Tank Pressure Control: Ensure the liquid oxygen pressure within the tank remains within a safe range. Monitor and control the tank's pressure to avoid risks from excessive or insufficient pressure.
Leakage and Fire Prevention: Regularly inspect the seals of storage tanks and associated pipelines to prevent oxygen liquid leaks. Oxygen liquid is highly flammable and fire prevention measures must be implemented to ensure no ignition sources are present around the storage tanks.
Explosion Prevention Measures: Oxygen in the liquid oxygen tank may cause an explosion upon contact with flammable substances. Ensure there are no flammable items around the tank and implement explosion prevention measures, such as explosion-proof electrical equipment and static grounding.
Safety valves and exhaust systems: Tanks should be equipped with safety valves and exhaust systems to prevent overpressure conditions. Ensure the proper operation of the safety valves and the unobstructed flow of the exhaust system.
Routine Maintenance and Inspection: Regularly maintain and inspect the storage tanks, including cleaning, coating protection, and anti-corrosion treatment. Ensure the structural integrity and safety of the tanks.
Safety Operation and Training: Operators must undergo relevant safety training, familiarize themselves with the safe operating procedures for liquid oxygen tanks and emergency response measures. Adhere to correct operational steps to ensure safe operation.
Environmental Monitoring: Regularly monitor environmental parameters such as oxygen concentration and temperature around the storage tanks to ensure safety.
Emergency Preparedness: Develop an emergency response plan including measures for leaks, fires, and explosions. Equip with appropriate emergency equipment and firefighting supplies to handle unforeseen incidents.
Above are some safety issues to be aware of when using 50 cubic liquid oxygen tanks. To ensure safety, it is recommended to follow relevant safety regulations and operating guidelines, and seek assistance and guidance from professionals when necessary.

Low-temperature liquid oxygen storage tanks typically require some safety accessories to ensure safe operation and to address potential risks. The following are some common safety accessories for low-temperature liquid oxygen storage tanks:
Pressure Sensor: Used to monitor pressure changes within storage tanks. Should the pressure exceed the set range, it will trigger alarms or automatically stop filling measures to prevent overpressure in the tank.
Safety Valve: Used 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.
Pressure relief device: Used to release gas into a safe area when the pressure inside the storage tank is too high, thereby reducing the pressure on the tank. The pressure relief device typically includes relief valves, relief pipes, etc.
Level sensor: Used to monitor the level change of liquid oxygen inside the storage tank to ensure an adequate supply of liquid oxygen and prevent overfilling.
Temperature Sensor: Used to monitor temperature changes within storage tanks to ensure the liquid oxygen inside remains within a safe temperature range.
Fire Detectors and Fire Suppression Systems: Designed to monitor fire risks around storage tanks and activate fire suppression systems as needed to prevent the spread of fire to other areas.

Liquid nitrogen storage tanks are used for storing and transporting liquid nitrogen. To ensure safe operation, here are some common operational safety procedures for liquid nitrogen storage tanks:
Tanks Installation: Tanks should be installed on a solid and level foundation, far from fire sources and flammable materials. Good ventilation around the tank is required to prevent gas accumulation. The tank should maintain a safe distance from other equipment and buildings.
Liquid Nitrogen Filling: When filling with liquid nitrogen, use appropriate liquid nitrogen transfer equipment to avoid direct contact. During the filling process, monitor and control the flow and pressure of liquid nitrogen to prevent over-filling and excessive tank pressure.
Tank Pressure Control: Tanks should be equipped with pressure control devices to ensure internal pressure remains within a safe range. Regularly inspect and maintain these devices to ensure proper operation.
Leak Detection and Alarm Systems: Storage tanks should be equipped with leak detection and alarm systems to promptly detect and alert of any leaks. Regularly inspect and maintain the leak detection equipment to ensure proper functioning.
Fire and explosion prevention measures: A fire-resistant buffer zone should be established around the storage tank, keeping it away from fire sources and flammable materials. The tank itself should adopt fire and explosion prevention measures, such as fire-resistant coatings, explosion-proof devices, etc., to prevent fires and explosions.
Regular Inspections and Maintenance: Regularly inspect the tank's exterior, valves, and connections to ensure they are intact and undamaged. Conduct regular leak detection and pressure tests to ensure the tank's safety performance meets requirements.
Safety Training and Awareness Enhancement: Conduct safety training for operators to enhance their awareness and ability in the safe operation of liquid nitrogen tanks. Regularly hold safety training and drills to respond to emergencies.
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.
Note that the above are some common protective procedures, which may vary depending on the type of tank and application. When using liquid nitrogen tanks, operate according to relevant specifications and standards, and consult with experts to ensure safety and effectiveness.
