Vacuum Insulated Pipe Technology Design and Features

1. The inner tube has a contraction 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 known as vacuum flange connection, manufactured in segments, with vacuum flanges connecting pipe sections;

2. Welded connection, commonly known as welded connection, with joints of cryogenic insulated pipes welded on-site and insulated locally;

3. Professional guidance for installation;

4. Shortens installation time, reduces installation workload, and lowers installation costs.
