FIELD: pipelines.
SUBSTANCE: invention relates to pipeline engineering. Pipeline is made from interconnected multicomponent pipes. Multicomponent pipes consist of at least two concentrically arranged layers. First layer is an internal conducting polymeric sealed layer. Second layer is external composite concrete layer. Composite concrete layer is equipped with a frame from reinforcement rods arranged concentrically and longitudinally to axis of multicomponent pipe. Lengthwise rods extend beyond ends of concrete composite layer. Internal conducting polymer layers of adjacent multicomponent pipes are connected to each other. At that protruding longitudinal carcass rods of external concrete composite layer of adjacent multicomponent pipes located longitudinally to pipeline axis are connected while space between end faces of concrete composite layer is filled with hardening material.
EFFECT: technical result is possibility of pulling and horizontally directed drilling at construction of pipelines.
