FIELD: construction.
SUBSTANCE: composite pipe comprises asbestos-concrete pipe or concrete basic pipe and outer coating made of composite-fiber material whose fibers are oriented in peripheral and axial directions. The ring fibers are preliminary stretched. The outer coating embraces the outer cylindrical surface and faces of the basic pipe, completely or in part, or fills the ring grooves formed from both ends of the basic pipe. The method comprises pressing the basic pipe before winding, winding the outer coating made of composite-fiber material on the basic asbestos-concrete or concrete pipe, stretching the ring layers during winding, and solidifying the composite material.
EFFECT: enhanced strength.
