FIELD: machine building.
SUBSTANCE: invention relates to machine building, particularly, to production of composite pipes with annular reinforcements. Elastic layer is installed on the mandrel and grooves are formed. Several layers of preform are applied by means of radial weaving and pressed into mandrel slots. By reinforcement grooves annular reinforcements are laid in grooves. Outer layers of shell are applied on mandrel. Moulding is performed by transfer method.
EFFECT: higher strength of pipe made from composite materials.
