Liquid nitrogen storage tanks specification
Liquid nitrogen storage tanks are equipment used to store liquid nitrogen and are commonly used in industrial, laboratory and medical fields. Here are some key features of liquid nitrogen storage tanks:
Storage of liquid nitrogen: The main function of the liquid nitrogen storage tank is to store liquid nitrogen and cool the gaseous nitrogen to an extremely low temperature (about -196 degrees Celsius or -321 degrees Fahrenheit) to achieve a liquefied state.
Double-wall design: Liquid nitrogen storage tanks often feature a double-wall design, with the outer wall providing structural support and insulation and the inner wall containing the liquid nitrogen. This helps reduce heat transfer and keeps the liquid nitrogen cold.
Vacuum insulation: To reduce heat conduction, liquid nitrogen storage tanks often use vacuum insulation technology. The vacuum layer reduces heat conduction between the tank and the external environment, ensuring that liquid nitrogen can be maintained at extremely low temperatures for a long time.
Safety valve and pressure control: Since liquid nitrogen has a relatively large expansion volume when it is liquid, the storage tank needs to be equipped with a safety valve and pressure control system to prevent the internal pressure from being too high and ensure the safe operation of the system.
Liquid level gauge: Liquid nitrogen storage tanks are usually equipped with a liquid level gauge to monitor the storage capacity of liquid nitrogen. This helps ensure that liquid nitrogen can be replenished when needed.
Corrosion-resistant materials: Due to the extremely low temperature and other chemical properties of liquid nitrogen, storage tanks are usually made of corrosion-resistant materials, such as stainless steel or other special alloys, to ensure the durability and safety of the equipment.
