Possible causes of leakage in liquid argon storage tanks include:
Design or Manufacturing Defects: Deficiencies in the design or manufacturing process, such as loose welds, improper material selection, or poor sealing, may lead to leakage issues in the storage tank.
Corrosion and Oxidation: Long-term exposure of liquid argon tanks to low temperatures can lead to corrosion and oxidation. These processes can damage the tank's surface protective layer, causing leakage issues.
Fatigue and stress cracking: Over time, due to temperature and pressure fluctuations, storage tanks may experience fatigue and stress cracking. These cracks can degrade the tank's sealing performance, leading to leaks.
Improper Operation: Failure to operate the storage tank according to specifications, such as overfilling liquid argon or excessive pressure, can lead to tank damage and leakage.
External Damage: The tank may be damaged by external factors such as mechanical impacts or objects.

Liquid Oxygen Storage Tanks Possess the Following Safety Technical Characteristics:
High-pressure Vessel: Liquid Oxygen Storage Tanks are high-pressure vessels capable of withstanding high pressure. Their design and manufacturing must comply with relevant standards and regulations to ensure the tank's strength and sealing integrity.
Low-temperature Storage: Liquid oxygen tanks are used to store liquid oxygen, with operating temperatures typically around -183 degrees Celsius. The material and insulation of the tank must be capable of withstanding low-temperature environments to prevent evaporation of the liquid oxygen and the penetration of external heat.
Fireproof Design: Liquid oxygen contains a high oxygen content, which is prone to cause fires. The design of liquid oxygen storage tanks must incorporate fireproof measures, such as installing fire walls and using fire-resistant coatings, to prevent fire outbreaks and spread.
Leak Control: Leaks in liquid oxygen storage tanks can lead to increased oxygen concentrations, heightening the risk of fire and explosion. Tanks must be equipped with leak detection and alarm systems to promptly detect and control leaks, and to implement appropriate emergency measures.
Electrostatic Protection: The accumulation of static electricity in liquid oxygen tanks may cause sparks, increasing the risk of fire. Tanks must be equipped with electroconductive materials and antistatic devices to reduce the buildup and discharge of static electricity.
Safety valves and pressure control: Liquid oxygen storage tanks must be equipped with safety valves and pressure control devices to ensure the internal pressure of the tank remains within a safe range. When the pressure exceeds the set value, the safety valve will automatically release pressure to protect the tank's safety.
Regular inspections and maintenance: Liquid oxygen tanks require regular checks and maintenance.
