Technical Design and characteristics of vacuum insulated Tube 1. Shrinkage rate of inner tube is 0.3% at liquid nitrogen temperature. For Rigid Tube, necessary compensator is set; 2. Install high vacuum multi-layer insulated low temperature globe valve, check valve, emergency shut-off Valve and safety relief system in the pipeline; The internal and external pipes are all Austenitic stainless steel 06Cr19Ni10(or customized according to customer’s requirements) . The interlayer adopts advanced special multi-layer thermal insulation material and gas adsorbent. The support with low thermal conductivity is applied in many industries such as industrial gas, medicine, biology, electronics, aviation, automobile, beverage, etc. . Vacuum insulation pipe installation features 1, plug-and-pull connection, commonly known as the vacuum flange connection, sub-production, between the pipe sections using vacuum flange connection 2, welding connection, commonly known as welding connection, sub-production of low-temperature insulation pipe joint welding, using site insulation 3, professional guidance installation 4, shorten the installation time, save installation workload, reduce installation costs
