Liquid nitrogen tanks feature the following characteristics during the construction process:
Low-Temperature Construction: The construction of liquid nitrogen tanks must be carried out in low-temperature environments, as the boiling point of liquid nitrogen is low, approximately -196 degrees Celsius. Construction personnel must take appropriate protective measures, such as wearing insulated clothing and gloves, to protect themselves from low-temperature injuries.
Welding Technology: Extensive welding is required during the manufacturing process of liquid nitrogen tanks, including the bonding of wall panels, bottom plates, top plates, and weld seams. Welding technology is crucial for the quality and safety of the tanks, necessitating the use of appropriate welding methods and materials to ensure the strength and sealing integrity of the welds.
Insulation Layer Installation: Liquid nitrogen tanks must have excellent insulation properties to minimize heat conduction and retain the low temperature state of liquid nitrogen. The installation of the insulation layer requires materials such as polyester foam and glass wool, ensuring the thickness and quality of the insulation layer.
Proper installation steps for liquid nitrogen tanks are as follows:
Site Preparation: Select a suitable site for tank installation, ensuring it is level, sturdy, and has adequate load-bearing capacity. The site should be far from flammable, explosive materials, and other hazards.
Foundation Construction: Construction of the foundation based on the tank's dimensions and weight, including excavation of the foundation pit and pouring of concrete foundation. The design and construction of the foundation should comply with relevant standards and specifications.
Tank Installation: Transport the tank to the site and perform a vertical installation. Appropriate lifting equipment and safety measures are required during the installation process to ensure the stability and safety of the tank.
Pipe Connections: Connect the storage tank to the relevant pipeline system as required, including intake pipes, exhaust pipes, and liquid supply pipes, etc. Sealing and testing must be carried out during the connection process to ensure pipeline safety.

Standard parameters for liquid oxygen storage tanks typically include:
Capacity: The capacity of liquid oxygen tanks is typically expressed in liters or cubic meters, with common ranges varying from a few liters to several thousand liters.
Work Pressure: The working pressure of liquid oxygen tanks is typically expressed in megapascals (MPa) or bars (bar), with a common working pressure range varying from 0.2 MPa to 2.5 MPa.
Design Temperature: The design temperature for liquid oxygen tanks is typically expressed in degrees Celsius, with common design temperature ranges varying from -196°C to -150°C.
Material: The main material for liquid oxygen storage tanks is usually stainless steel, which offers excellent corrosion resistance and low-temperature properties.
Insulation Layer: Liquid oxygen tanks are typically equipped with an insulation layer to reduce evaporation losses of liquid oxygen. The material for the insulation layer is usually a multi-layer composite material or foam glass.
Safety valve: Liquid oxygen storage tanks must be equipped with a safety valve to control the internal pressure of the tank and prevent bursting due to excessive pressure.
Leak Detectors: Liquid oxygen storage tanks are typically equipped with leak detectors to promptly detect and alarm any leaks in liquid oxygen.
Appearance Design: The appearance design of liquid oxygen storage tanks generally conforms to relevant standards and regulations, including exterior color, markings, and safety warning signs.
Note that the specific parameters of liquid oxygen tanks may vary depending on the manufacturer and application requirements; the above are merely general standard parameters. In actual use, select the appropriate liquid oxygen tank based on the specific circumstances.

To maintain the stability of liquid argon tanks, the following details should be noted:
Basic Design: The foundation design of the tank should comply with relevant standards and specifications to ensure stability and load-bearing capacity. The foundation must be sufficiently robust and seismic-resistant to withstand the impact of external forces and natural disasters such as earthquakes.
Foundation Construction: During the foundation construction process, ensure the foundation is level and even to prevent any tilting or uneven settlement. Additionally, the concrete pouring must comply with construction standards to ensure the quality and strength of the concrete.
Installation Process: During the storage tank installation, appropriate lifting equipment and safety measures must be used to ensure the tank is vertically installed and stable. Avoid severe vibrations and collisions during the process to prevent damage or deformation to the tank.
Support Structure: The support structure of the tank should be designed reasonably to ensure stability and load-bearing capacity. It should be made of sturdy materials and utilize appropriate connection methods to withstand external forces and the pressure of the liquid inside the tank.
Safety Equipment: Tanks should be equipped with safety devices such as pressure relief valves and level alarms to ensure timely measures can be taken in abnormal situations, ensuring the safety of the tank.
Regular Inspections and Maintenance: Conduct regular inspections and maintenance on liquid argon tanks, including visual inspections, pressure tests, and leak detection, as well as non-destructive testing and material analysis as required. Promptly identify and address any issues with the tanks to ensure their stability and safety.
Note that the installation of liquid argon tanks should be performed by experienced personnel and in accordance with relevant safety operation procedures and standards. During the installation process, operations should be strictly conducted according to the manufacturer's installation guidelines and requirements to ensure the stability and safety of the tank.

Liquid oxygen storage tanks offer the following advantages:
High Storage Density: Liquid oxygen tanks can store oxygen in liquid form, which has a higher storage density compared to gas storage. This means more oxygen can be stored in a limited space, providing extended supply time.
High Purity Oxygen Supply: Liquid oxygen tanks can provide high purity oxygen supply. After undergoing refrigeration and purification processes, liquid oxygen can yield high purity oxygen, meeting the requirements of various applications such as industry and scientific research.
User-friendly: The liquid oxygen tank features ease of use. It is equipped with devices such as level gauges and pressure gauges inside, allowing for convenient monitoring of the liquid level and pressure. Additionally, the tank is fitted with safety devices like pressure relief valves and level alarms to ensure safe operation and usage.
Long-term Storage: Liquid oxygen tanks are suitable for long-term storage of oxygen. The low temperature properties of liquid oxygen can slow down the evaporation and oxidation of oxygen, extending its storage life. This is beneficial for applications requiring long-term oxygen storage, such as institutions, laboratories, and industrial production.
In summary, liquid oxygen tanks offer advantages such as high storage density, pure oxygen supply, ease of use, and long-term storage. This makes liquid oxygen tanks a reliable choice for oxygen supply, widely used in industrial and research fields.
