Vacuum Insulated Pipe Technology Design and Features

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 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 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 various 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 connections, commonly known as vacuum flange connections, are manufactured in segments, with vacuum flanges connecting the pipe sections;

2. Welded connections, commonly known as welded joints, involve on-site insulation for the welded joints of cryogenic insulated pipes manufactured in segments;

3. Professional guidance for installation;

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