杜瓦瓶氩气氮气氧气

Cryogenic liquid containers are double-walled vacuum vessels with multilayer insulation in the space between the walls. This minimizes heat transfer from the outside environment to the inner container, allowing the cryogenic liquid to remain cold for extended periods. The inner container is typically made of stainless steel, while the outer container can be made of stainless steel, aluminum, or other materials.
 

Cryogenic liquid containers are used in a wide variety of applications, including:

• Medical: Storing medical gases such as oxygen, nitrogen, and helium for use in hospitals and other medical facilities.
• Scientific research: Storing gases and other materials at very low temperatures for research purposes.
• Industrial: Storing and transporting liquefied natural gas (LNG) for use as a fuel, and other industrial gases such as argon and nitrogen.
• Food processing: Rapidly freezing and preserving food products.

Safety Precautions

Cryogenic liquids are extremely cold and can cause serious injuries if not handled properly. It is important to follow all safety precautions when working with cryogenic liquids, including wearing appropriate personal protective equipment (PPE) such as cryogenic gloves, safety glasses, and a face shield.
