FIELD: transportation.
SUBSTANCE: multi-channel pipeline comprises an outer pipe and at least one inner pipe, laid on the inner surface of the outer pipe, in the gap between which the external channel is formed, and in the inner pipe - the internal channel thermally insulated by the medium being transported via the external channel, wherein the inner channel has the fixators of its position in the multi-channel system, which are constructed as bushings envelopping the inner pipe surface, the outer surface of the bushings having radial stops with the outer pipe in the form of hydro cylinders, the inner surface of the bushings in the radial stops zone having round pads of antifriction material, mounted in a sliding fit with the inner pipe surface and glued to the inner surface of the bushings.
EFFECT: increased reliability and durability of the multi-channel pipeline.
