Vacuum insulation pipeline

1.Overview
Vacuum insulation pipeline is used to transport cryogenic liquid and gas such as liquid nitrogen, liquid helium, liquid oxygen, liquid argon, liquid natural gas, etc. 

2. Structures
Under normal circumstances, both inner and outer pipelines are made of seamless stainless steel. According to the site requirement and temperature compensation need, the inner pipeline and outer pipeline or both the inner and outer pipelines at the same time (in whole or in part) are made of sylphon bellows. 
The bayonet connection type or flange connection type are adopted between the vacuum insulation pipelines, and the inner pipeline is equipped with a safety valve. 
According to requirement, valves as well as test and monitoring divices for parameters such as flow rate, pressure, temperature and so on can be set in the middle of the vacuum insulation pipelines.
   
3. Properties
The following table shows the properties of vacuum insulation pipelines used for transporting liquid oxygen, nitrogen or argon. The vacuum insulation pipelines used for transporting cryogenic helium and liquid helium are usually designed according to the special requirements of users, and the smallest inner diameter is 4mm. A typical insulation parameter of liquid helium pipeline is heat leakage at liquid helium temperature which is less than 1.0W /m.
