During the operation of low-temperature storage tanks, it is indeed necessary to avoid wrinkling. Wrinkling refers to the occurrence of creases or deformation in the tank walls, which may lead to a decrease in the structural strength of the tank, and even trigger leaks or ruptures.
Here are some precautions to avoid tank squeezing in low-temperature storage:
Tank Design: Select an appropriate tank design that can withstand the pressure and weight of low-temperature liquids. The tank's wall thickness, support structure, etc., should comply with relevant standards and regulations.
Material Selection: Choose materials suitable for low-temperature environments with sufficient strength and low-temperature resistance. Common materials include low-temperature steel, stainless steel, etc.
Insulation Layer for Storage Tanks: The design and construction of the insulation layer must meet the requirements to ensure effective reduction of heat conduction and temperature fluctuations. The material and thickness of the insulation layer should be selected based on specific conditions.
Tank Operation: During the loading and unloading of liquids in the tank, it is essential to avoid rapid or excessive fluid flow to minimize impact and stress concentration on the tank walls.
Tank Maintenance: Regularly inspect and maintain the structure and insulation of the tanks to ensure they remain undamaged. Any abnormalities or damage should be repaired or replaced promptly.
Temperature Control: During the operation of low-temperature liquid storage tanks, it is crucial to strictly control the temperature difference between the inside and outside of the tank to avoid excessive temperature changes and thermal stress.
In summary, preventing crimping in low-temperature storage tanks hinges on proper design, material selection, insulation layer installation and maintenance, as well as strictly controlling temperature variations. Regular inspections and maintenance are also crucial measures for ensuring the safe operation of the tanks.

The stable pressure design of a 15 cubic meter liquid argon storage tank requires consideration of 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 properties and usage conditions of liquid argon.
Regulation System: Select an appropriate regulation system to maintain stable pressure within the storage tank. The regulation system typically includes components such as pressure regulators, pressure sensors, and control valves, which are used to monitor and adjust the pressure inside the tank.
Pressure Sensor: Install a pressure sensor to monitor the pressure changes inside the storage tank in real-time. The sensor transmits pressure signals to the pressure regulation system, enabling timely adjustment of the control valve to maintain stable pressure within the tank.
Control Valve: Select a suitable control valve for regulating the gas flow and pressure within the storage tank. The control valve should possess excellent regulating performance and stability to ensure the pressure within the tank stays 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 Regulation System Control: Configure an appropriate control system for monitoring and regulating the operation of the voltage regulation system. The control system can achieve 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 operational 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 advisable to consult with experienced engineers or relevant organizations to ensure the reliability and safety of the system.

Maintenance and protection of liquid argon tank accessories are crucial for ensuring the normal operation and extending the service life of the tank. The following are general methods for the maintenance and protection of liquid argon tank accessories:
Valve Maintenance: Regularly inspect and maintain valves within the tank accessories, including intake valves, exhaust valves, and safety valves. Ensure the valves operate smoothly and reliably with no leaks or jamming. Regularly lubricate the valves and clean any debris and dirt.
Pressure Relief Device Maintenance: The pressure relief devices (such as safety valves) in the liquid argon storage tank accessories are critical components for ensuring the safety of the internal pressure. Regularly inspect and test the operational status of the pressure relief devices to ensure proper functioning. Clean and repair as necessary.
Sensor and Instrument Maintenance: Sensors and instruments in the liquid argon storage tank accessories are used to monitor and control parameters such as tank temperature and pressure. Regularly calibrate and inspect the accuracy and reliability of the sensors and instruments. Maintain the cleanliness and proper functioning of the sensors and instruments.
Insulation Layer Protection: The insulation layer of liquid argon storage tank accessories is crucial for maintaining the low temperature state of liquid argon. Regularly inspect the integrity and insulating performance of the insulation layer, and repair or replace any damaged insulation material. Avoid mechanical damage or contamination to the insulation layer.
Cleaning and Corrosion Protection: Regularly clean the accessories of the storage tank, removing impurities and dirt from the surface. Periodically inspect and maintain the corrosion-resistant coating on the accessories to prevent corrosion and oxidation.
Regular inspections and maintenance: Conduct comprehensive inspections and maintenance of liquid argon cylinder accessories on a regular basis, including the exterior, fittings, and seals. Promptly identify and address any damage, leaks, or other issues with the accessories.
Record and Document Management: Document each maintenance and service result, including the service date, content, issues found, and measures taken. Establish comprehensive management records and documents for tracking and managing the operation of the attachments.
Note that maintenance and protection of liquid argon cylinder accessories should be performed by trained personnel, following relevant specifications and standards. Ensure safety during maintenance and operation, and consult with experts for accurate guidance.

To prevent liquid oxygen storage tanks from bursting, the following measures can be taken:
Regular Inspections and Maintenance: Conduct regular inspections and maintenance on liquid oxygen tanks, including checking the tank's exterior, welds, valves, and fittings, to ensure they are intact and undamaged. Regularly clean the tank to remove any impurities and dirt adhering to its surface.
Pressure Control: Storage tanks should be equipped with pressure control devices to ensure internal pressure is within a safe range. Regularly inspect and adjust the pressure control devices to ensure proper operation.
Temperature Control: The liquid oxygen tank should be maintained within an appropriate temperature range to prevent excessive heat from causing increased pressure. Ensure the tank's insulation is intact to minimize heat conduction and loss.
Fire Prevention Measures: Liquid oxygen has a high oxygen content and flammability, thus strict fire prevention measures are required. A fire separation zone should be established around the storage tank, with smoking and open flames prohibited. Ensure the storage tank maintains a certain fire safety distance from other facilities.
Pressure relief devices and safety valves: Liquid oxygen storage tanks should be equipped with pressure relief devices and safety valves to prevent overpressure and sudden pressure increases. Regularly inspect and test the operational status of the pressure relief devices and safety valves to ensure their proper functioning.
Tank Operation Standards: Adhere strictly to the operational specifications and safety requirements for liquid oxygen tanks. Operators must be trained and knowledgeable about the tank's characteristics and operation techniques. Avoid operational errors and violations.
Emergency Preparedness: Establish emergency response plans and conduct drills to address potential accidents. Train operators in emergency response capabilities to ensure timely and effective handling.
