An equipment for positioning, stamping barcodes and packing separate hydraulic connections includes two conveyor belts interconnected, a receiver consisting of an inclined tray coupled to the conveyor belts that directs parts to a longitudinal positioner, which contains gutters that direct the parts to a set of helical rollers equipped with helical gears that rotate in opposite directions; a pair of sensors, a first sensor of contact with the part and a sensor after to prevent back up when tipping; a reducer guide with automatic mechanism controlled by a pneumatic cylinder; pneumatic tippers for determining which side the part should tip over; bulkheads, which allow the parts to first hit an upper bulkhead; a motor shaft connected to a side guide that restricts the positioning; a laser or ink-jet equipment for stamping a production and traceability information; and a packaging machine that prints a traceability code of parts package.

The polymeric pipes reinforced with a metal casing are used for transporting oil and gas, acids, alkali products, drinking water and industrial water, and also in the transportation of aggressive and neutral pulps. A metal-containing polymeric reinforced pipe includes a welded metal casing and a polymeric matrix having an amorphous-phase-based molecular structure. The metal-containing polymeric reinforced pipe is produced by extrusion moulding with simultaneous feeding of a polymer melt and the reinforcing metal casing into the mould cavity, followed by intensive cooling of the internal and external surfaces of the pipe being moulded. The invention increases the quality and endurance limit in the radial direction of the metal-containing polymeric reinforced pipe, productivity of the process for manufacturing the pipe, and also the strength and technological effectiveness of a pipeline constructed from the pipes produced.
