I. Technical Design and Features of Vacuum Insulated Pipes

1. The inner pipe has a shrinkage rate of 0.3% at liquid nitrogen temperature. For rigid pipes, necessary compensators are installed;

2. High-vacuum multilayer insulated cryogenic globe valves, check valves, emergency shut-off valves, and safety relief systems are installed on the pipeline;

3. Push-fit vacuum connection joints feature low heat leakage, no frosting, and anti-frosting properties;

4. Both inner and outer pipes 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 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, with segmented fabrication and vacuum flange connections between pipe sections;

2. Welded connection, commonly referred to as welded connection, with on-site insulation for welded joints of segmented cryogenic insulated pipes;

3. Professional guidance for installation;

4. Shortened installation time, reduced installation workload, and lower installation costs.
