During the operation of low-temperature storage tanks, it is indeed necessary to avoid the occurrence of wrinkling. Wrinkling refers to the phenomenon where the tank walls develop creases or deformations, which may lead to a decrease in the structural integrity of the tank and could even cause leaks or ruptures.
Here are some precautions to avoid pressing during 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, supporting structure, etc., should comply with relevant standards and specifications.
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 variation. The materials and thickness of the insulation layer should be selected based on specific circumstances.
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 tanks to ensure they are in perfect condition. 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 tank deformation at low temperatures hinges on proper design, material selection, insulation installation and maintenance, as well as strictly controlling temperature variations. Regular inspections and maintenance are crucial for ensuring the safe operation of the tank.

The stable pressure design of a 15-cubic-meter liquid argon storage tank should consider 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 operating conditions of liquid argon.
Regulating System: Choose an appropriate regulating system to maintain stable pressure within the storage tank. The regulating 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 Sensors: Install pressure sensors for real-time monitoring of pressure changes within the storage tank. The sensors transmit pressure signals to the voltage regulation system, enabling timely adjustment of the control valve's opening to maintain stable pressure within the tank.
Control Valve: Select an appropriate control valve for regulating 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 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 according to the design pressure and capacity of the storage tank.
Voltage Stabilization System Control: Equipped with a suitable control system for monitoring and regulating the operation of the voltage stabilization system. The control system enables automatic adjustments and alarm functions to ensure stable and safe pressure within the storage tank.
It's important to note that the design of the pressure-stabilizing system should be tailored to the specific engineering requirements and usage conditions of the liquid argon storage tank, adhering to relevant local regulations, standards, and specifications. When designing and installing the pressure-stabilizing system, it's advisable to consult with an engineer or a relevant institution for guidance 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 maintaining and protecting liquid argon tank accessories:
Valve Maintenance: Regularly inspect and maintain valves within the tank accessories, including intake valves, exhaust valves, and safety valves. Ensure valves operate smoothly and reliably with no leaks or jamming. Regularly lubricate valves and remove any debris and dirt.
Pressure Relief Device Maintenance: The pressure relief devices (such as safety valves) in the liquid argon storage tank accessories are crucial 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 needed.
Sensor and Instrument Maintenance: Sensors and instruments in the liquid argon storage tank accessories are used to monitor and control parameters such as the temperature and pressure of the tank. Regularly calibrate and check the accuracy and reliability of the sensors and instruments. Keep the sensors and instruments clean and in normal working condition.
Insulation 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 damaged insulation materials. Avoid mechanical damage or contamination to the insulation layer.
Cleaning and Corrosion Protection: Regularly clean the accessories of the 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 appearance, 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 dates, services performed, issues found, and measures taken. Establish comprehensive management records and documents for tracking and managing the operation of attachments.
Note that maintenance and protection of liquid argon tank accessories should be carried out by trained personnel, following relevant specifications and standards. Ensure safety during maintenance and operation, and consult experts for accurate guidance.

To prevent liquid oxygen tanks from bursting, the following measures can be taken:
Regular inspections and maintenance: Conduct regular checks and maintenance on liquid oxygen tanks, including inspecting the tank's appearance, welds, valves, and connections, to ensure they are in perfect condition without any damage. Regularly clean the tank to remove any impurities and dirt adhering to the surface.
Pressure Control: Storage tanks should be equipped with pressure control devices to ensure internal pressure remains 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 an increase in 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-resistant buffer zone should be established around the storage tank, with smoking and open flames prohibited. Ensure the storage tank maintains a sufficient fire-resistant distance from other facilities.
Pressure Relief Device and Safety Valve: 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 they are functioning properly.
Tank Operation Guidelines: Adhere strictly to the operational specifications and safety requirements for liquid oxygen tanks. Operators must be trained and familiar with 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 skills to ensure timely and effective actions.
