FIELD: valves industry.
SUBSTANCE: invention relates to high pressure pipes made of a synthetic material and to a method for manufacturing pipes. High pressure pipe has a wall of the first layer of synthetic material and reinforcing material in the wall. Reinforcing material has a tubular shape and is placed inside the first layer in a molten state of the latter. Position of the reinforcing material is unstable and the distances from the reinforcing material to the cylindrical inner surface and the cylindrical outer surface are uneven. Pipe is hardened by cooling.
EFFECT: invention makes it possible to increase the compression strength of the pipe and to reduce the possibility of deformation, as well as to simplify the method of making the pipe.
