The pressure stabilization design for a 15-cubic-meter liquid argon storage tank should take into account 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 usage conditions of liquid argon.
Regulation System: Choose 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 for monitoring and adjusting the pressure inside the tank.
Pressure Sensors: Install pressure sensors for real-time monitoring of pressure changes inside the storage tank. The sensors transmit pressure signals to the voltage regulation system to promptly adjust the opening of the control valve, ensuring the stability of pressure within the tank.
Control Valve: Select an appropriate control valve for regulating the gas flow and pressure within the storage tank. The control valve should have 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 based on the design pressure and capacity of the storage tank.
Voltage Stabilization System Control: Configure an appropriate control system for monitoring and controlling the operation of the voltage stabilization system. The control system can achieve automatic adjustment and alarm functions to ensure stable and safe pressure within the storage tank.
It's important to note that the design of the voltage regulation system should be tailored to the specific engineering requirements and operational conditions of the liquid argon storage tank, adhering to relevant local laws, regulations, and standards. When designing and installing the voltage regulation system, it is advisable to consult with a qualified engineer or seek guidance from relevant institutions to ensure the reliability and safety of the system.

During the welding process of low-temperature liquid storage tanks, controlling the occurrence of welding cracks is crucial. The following are some methods and measures to control welding cracks:
Appropriate Welding Processes: Select the appropriate welding process and parameters to minimize welding heat input and thermal stress. Methods with low heat input, such as pulse welding and laser welding, can reduce the temperature gradient and residual stress in the焊接 heat-affected zone.
Preheating and Post-Weld Heat Treatment: Perform appropriate preheating before welding to enhance material toughness and reduce thermal stress. Conduct suitable post-weld heat treatment, such as annealing or stress-relief heat treatment, to minimize residual stress and improve the toughness of the weld.
Select appropriate welding materials: Choose welding materials with good toughness and crack resistance to minimize the occurrence of welding cracks. Select the appropriate welding material based on the storage tank's operating conditions and requirements, such as low-alloy steel, stainless steel, etc.
Control Welding Process: Regulate parameters and operations during the welding process to minimize the risk of welding cracks. Pay attention to factors such as welding speed, current, voltage, and welding sequence to avoid overheating or rapid welding, thereby reducing the accumulation of thermal and residual stresses.
Inspection and Evaluation: Conduct non-destructive testing on weld seams post-welding, such as ultrasonic and X-ray testing, to assess welding quality and detect cracks. Promptly identify and repair welding cracks to ensure the integrity and safety of the weld joints.
It's important to note that controlling welding cracks is a complex process that requires considering multiple factors, such as materials, welding techniques, and operations. When welding low-temperature liquid storage tanks, it's advisable to consult with a welding engineer or relevant institutions for guidance to ensure welding quality and the safety of the tank.
