Description

Technical Field

[0001] The utility model belongs to the technical field of liquid nitrogen transport hoses, in particular to a liquid nitrogen metal hose. Background Art

[0002] Liquid nitrogen refers to the liquid obtained by inert, colorless, odorless, non-corrosive, and non-flammable nitrogen in an extremely low temperature environment. Liquid nitrogen is an inert, colorless, odorless, low-viscosity, non-corrosive, non-flammable, transparent liquid at an extremely low temperature. When it vaporizes, it absorbs a large amount of heat and causes frostbite. Nitrogen makes up most of the atmosphere. Metal hoses are required for the transportation of liquid nitrogen. Metal hoses are installed in liquid transportation systems as a flexible pressure-resistant pipe fitting to compensate for the mutual displacement of the connection ends of pipelines or machines and equipment, absorb vibration energy, and can play a role in vibration reduction and silencing. It has many advantages such as good flexibility, light weight, corrosion resistance, fatigue resistance, and high and low temperature resistance.
