Vacuum super-insulated pipelines
We produce vacuum-insulated pipe systems necessary for the transport of cryogenic liquefied gases – nitrogen, oxygen, argon, helium and hydrogen.
The equalization of the contraction between the vacuum jacket and the inner medium-conveying pipe is done by installing expansion bellows.
To reduce heat ingress, low-loss supports are used between the outer and inner pipe.
Pipeline parts are coupled by means of flanged connections or welded sleeves.
A combined evacuation and safety valve is positioned in every vacuum space. It allows the connection of a vacuum lock with pump and protects the outer pipe against excess pressure. Inner and outer pipes are subjected to a helium leakage test during production and before delivery.
To maintain the insulation vacuum, active adsorption materials are installed in the medium-conveying pipe.
