Liquid nitrogen hose/ Vacuum hose / Vacuum pipe/ Stainless steel vacuum insulate hose / LNG Cryogenic hose

Liquid nitrogen hose

Vacuum insulate flexible hose / Thermal insulate hose



Liquid nitrogen hose / Vacuum insulate hose is mainly applied to: low temperature tank car filling and unloading process;

Connection transformation between low temperature storage tank and cryogenic liquid equipment;
Conversion between vacuum low temperature hose/pipe and cryogenic liquid equipment;
Other places with special technology and process requirements.

Characteristics of high vacuum multiple layer adiabatic low temperature hose:

Using the special customized double layer stainless steel metal hose, sandwich special multiple layer insulation composite
material and keep high vacuum, cooling effect is good, in the process of using the hose outside surface is not sweating, no frosting;

• support between internal and external tubes with minimal thermal conductivity

Small bending radius, easy to use, the length can be customized according to the requirements of the user.

• it can be connected to a vacuum pipe.

In order to reduce the loss of vaporization, the two ends of the vacuum hose can be connected to the flange or the tank and the special
quick fitting joint of the tank car.

Special required vacuum hose can be customized
