Transporting pipeline for cryogenic fluids such as liquid helium, with insulation round both pipes together and on rigid insulation carrier linked to pipes via spacers

摘要

The transporting pipeline includes internal pipes (2, 3) with a common insulation (4) round them, which sits on a rigid insulation carrier (5), connected to the pipes via spacers (6a, 6b) which are spaced out axially, fixed to the first pipe and able to slide along the second one. The carrier consists of successive components (5a, 5b) fixed to one spacer and able to slide relative to the next one.
