Rigid transfer line

To ensure that your project can be realized within a very short time, we are at your side from the very beginning. Together with you we carry out the planning, design and installation of the cryogenic piping system tailored to your plans.

A modular system specially developed for the nominal diameters DN 14 and DN 25 is suitable for a wide range of tasks and is available from stock in standard lengths of 3, 6 and 12 m.

  • Inner pipe made of highly corrosion-resistant, cold-resistant stainless steel (1.4301), completely welded
  • Combined vacuum closure and safety device protects the vacuum chamber against impermissibly high pressure
  • Expansion compensator for the compensation of thermal length changes
  • Multi-layer vacuum insulation through computer-optimized thermodynamic design
Productinformation

Convincing advantages:

  • Optically pleasing
  • Made of anti-magnetic, highly corrosion-resistant stainless steel, therefore also suitable for use in clean rooms and in the food industry
  • High thermal quality Through computer-aided optimized thermal design and multi-layer vacuum super insulation between inner and outer pipes.
  • Can be easily extended and combined by using plug-in couplings
  • Long service life of the vacuum by using adsorption material and special getters. Thereby you reduce your gas consumption and extend the maintenance intervals.
