Thermal performance
Cryogenic transfer lines Under vacuum lines

The thermal performance of a transfer line is estimated by the sum of the thermal losses of the internal supports and the radiation losses of the insulation. The vacuum in the intermediate wall means that there is no convective heat loss.

Heat flow through insulation is obtained by measurement and feedback. This flow depends on the type and number of insulation layers, the temperature gradient and the quality of insulation installation.

Heat flow through fixed and sliding supports is estimated by calculating their conductivity,...
