FIELD: oil industry.
SUBSTANCE: pipe comprises walls made of a solid layer of polymeric material, longitudinal reinforcing members arranged inside the polymeric material and are made of metallic belt, and transverse reinforcing members made of spiral metallic wire. The longitudinal members are inclined at an angle of 70-85 degrees to the axis of the pipe. The turns of the spiral of the transverse members are inclined to the axis of the pipe at an angle of 15-30 degrees.
EFFECT: expanded functional capabilities.
