FIELD: heat exchange.
SUBSTANCE: invention relates to pipe engineering and can be used in various heat-generating and heat-exchange plants, as well as supply networks or heat carrier circulation systems as a device regulating operational parameters of the moved working medium. Essence of the proposed invention consists in the fact that the multi-form composite pipeline contains an annular closed structure, wherein annular closed structure is made of spirally arranged longitudinal reinforcing elements, which are covered with strong films from outer and inner sides and connected to each other in distancing points by heat-sensitive rings.
EFFECT: technical result is providing control of operating parameters of pipeline moved working medium, by means of automatic change of shape of live section of pipeline, with accompanying increase of hydraulic stability and durability of engineering system.
