LNG high vacuum insulated low temperature pipeline

The LNG high vacuum insulation tube is composed of an inner tube, an outer tube and multiple layers of insulation materials. The multiple layers of insulation materials in the interlayer are compounded to reduce radiant heat transfer; the interlayer is pumped into a high vacuum state to reduce convection heat transfer; inside and outside The tubes are separated by materials with low thermal conductivity to reduce the heat transfer of the solids, so as to minimize the cooling loss of the inner tubes, and fully meet the long-distance transportation of low-temperature liquids (LOX, LIN, LAr, LH2, LHe, LNG).

Product Details

Technical design parameters of LNG high vacuum insulated cryogenic tube

●The shrinkage of the inner tube is 0.3% at the temperature of liquid nitrogen. For hard tubes, a compensator must be installed on the inner or outer tube

● Install high vacuum multi-layer insulation low-temperature shut-off valve, check valve, emergency shut-off valve and safety system directly on the pipeline

●Small heat leakage at the connection of the plug-in vacuum connector, no frost and dew

●Customers with special needs customize vacuum insulation piping system with special structure

Material selection of LNG high vacuum insulation low temperature tube

●Inner and outer pipes are special high-quality stainless steel pipes (SUS304)

●The current advanced special multi-layer insulation materials and gas adsorbent are used in the interlayer

●Low thermal conductivity support

Connection method of LNG high vacuum insulation cryogenic tube

●Plug-in connection (commonly known as vacuum flange connection)

●Welding connection (welding the joints of the vacuum tubes at the installation site)
