FIELD: pipeline engineering.
SUBSTANCE: polymeric reinforced pipe comprises grid frame made of longitudinal metallic rods and transverse rods made of high-module fibers or cords wound along the longitudinal rods. The grid frame in the polymeric unit has additional lateral layer made of metallic rods wound directly on the longitudinal metallic rods. The transverse reinforcing rods made of high-module fibers are wound to provide several mutually perpendicular layers and are housed in the polymeric unit from the outer side of the layer of the metallic transverse rods. The method comprises feeding the longitudinal metallic reinforcing rods to the mandrel, making the layer of transverse reinforce made of high-module fibers, and filling the frame with a polymer. The transverse reinforcing layer made of metallic rod is directly wound on the metallic longitudinal rods, the frame is filled with a polymer, and then several mutually perpendicular layers of the transverse rods are wound on the surface obtained. The polymer is poured again. The longitudinal metallic rods are fed to the mandrel until the cross-section of the pipe is defined.
EFFECT: enhanced strength.
