Design and Features of Vacuum Insulated Pipe Technology
1. The inner tube has a shrinkage rate of 0.3% at liquid nitrogen temperature. For rigid pipes, necessary compensators are installed;
2. High-vacuum multilayer insulated cryogenic shut-off valves, check valves, emergency shut-off valves, and safety relief systems are installed on the pipeline;
3. Plug-in vacuum connection joints feature low heat leakage, no frosting, and no icing;
4. Both inner and outer tubes are made of austenitic stainless steel 06Cr19Ni10 (or customized according to customer requirements);
5. Advanced specialized multilayer insulation materials and gas adsorbents are used in the interlayer;
6. Supports with low thermal conductivity;
7. Application fields: Industrial gases, medical, biological, electronics, aviation, automotive, beverage, and many other industries;
8. Transport media: Liquid nitrogen (LIN), liquid argon (LAr), liquid oxygen (LOX), liquefied natural gas (LNG).
Installation Features of Vacuum Insulated Pipes
1. Plug-in connection, commonly referred to as vacuum flange connection. Segmented fabrication with vacuum flange connections between pipe sections;
2. Welded connection, commonly referred to as welded connection. Segmented fabrication with welded joints for cryogenic insulated pipes, using on-site insulation;
3. Professional guidance for installation;
4. Shortens installation time, reduces installation workload, and lowers installation costs.
