Liquid nitrogen vacuum tube, stainless steel, cryogenic insulation vacuum, liquid oxygen, liquid argon, LNG pipe.

Vacuum Insulated Pipe Technology Design and Features

1. The inner tube has a shrinkage rate of 0.3% at liquid nitrogen temperature; for rigid pipes, 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. The interlayer uses optimized specialized multilayer insulation materials and gas adsorbents;

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), LNG.

Installation Features of Vacuum Insulated Pipes

1. Plug-in connection, commonly referred to as vacuum flange connection; segments are manufactured separately, and pipe sections are connected using vacuum flanges;

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

3. Professional guidance for installation;

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