Vacuum-insulated piping systems with multiple layer insulation (MLI). Expansion joints installed in the inner piping serve for compensating the thermal expansion between the vacuum shell and the media pipe.
Low-thermal transportation supports between the external and internal pipes are used to minimize the penetration of heat.

A combined vacuum and safety valve is provided for every vacuum. This valve protects the external pipe against excessively high pressure and guarantees after the installation of a vacuum sluice the setting-up of a vacuum respectively its reconstruction in case of a repair.
Active adsorption medium is provided at the media pipe for keeping the long-term vacuum.
