FIELD: pipeline engineering.
SUBSTANCE: pipe comprises conducting pipe, shell made of a polymeric material; and bearing-guiding means. The shell has bearing and guiding means defined by the group of hollow bearings projecting in the radial direction until it abuts against the outer side of the conducting pipe. According to the second version, the combined pipe has heat insulating and weighting coating.
EFFECT: enhanced reliability.
