Cryogenic Pipelines

  “Cryogenmash” PJSC designs, manufactures cryogenic pipelines of DN10 up to DN750 for transportation of liquid cryoproducts (nitrogen, oxygen, argon, liquefied natural gas) with minimum heat gains from environment.


A cryogenic pipeline is a coaxial double-walled pipeline with vacuum screen insulation.

According to the georeference, the cryogenic pipeline route is completed with the following components:

  • Cryogenic pipeline sections;
  • Compensator elements (expansion joints, metal hoses);
  • Connection elements (couplings, lenses, etc.);
  • Adsorption sections;
  • Vacuum ports for connecting evacuation means and vacuum control;
  • Supports, membrane safety devices and protective grounding devices.
  • Cryogenic pipeline sections are interconnected by welding.
