High vacuum multi-layer insulation low temperature pipeline

Main features of high vacuum multi-layer insulation low temperature pipeline:

Vacuum insulation cryogenic tube is composed of inner tube, outer tube and multiple layers of insulation materials, which are composed of multiple layers of insulation materials in the interlayer to reduce radiant heat transfer; the interlayer is pumped into a high vacuum state to reduce convection heat transfer; vacuum insulation The inner and outer tubes of the cryogenic tube are separated by materials with low thermal conductivity to reduce the heat transfer of the solid, thereby controlling the cooling loss of the inner tube to a minimum, and fully satisfying the long-distance transportation of cryogenic liquid.

Main technical parameters of high vacuum multi-layer insulation low temperature pipeline:

1. Pipeline design pressure: 1.6MPa～4.0MPa;

2. Design temperature: -196℃;

3. Applicable medium: LNG, LO2, LAr, LN2 and other low-temperature liquids

4. Connection form: vacuum flange connection, welding insulation connection, etc.
