<p>The system is provided for the integrated manufacturing of sockets in oriented pipes, with the possibility of regulating and distributing at will the thicknesses of the socket and making it possible to reinforce the traditionally weaker zones, without increasing the manufacturing process time. It basically comprises a support body (1), a slide block (2) sliding axially on the inside of the body (1) with its inner end (4) conical and equipped with means of heating (6), further comprising a slide rod (8) for the pushing of the corresponding blank (11), this rod having an axial and central orifice (9) for the introduction of expansion and cooling fluid, whilst the slide block (2) has orifices (7) for the intake of a lubricating fluid.</p> |
