Definitions

  • the utility model described in this application has a polyethylene pipe for making piping for distributing and transporting pressurised fluids. More particularly, this pipe model is fitted with a socketed end suitable for connecting to the end of another pipe of the same diameter, in order to fit the piping in line.
  • a first method that uses this technique is performed by placing a heated metal plate between the two ends of the pipes to be connected, which is removed after melting the ends of the pipes in contact with it, so that these ends come together and are pressed, thus permitting cohesion.
  • a second joining method of the ends of the pipes is based on projection welding the ends by using a circular joint containing an electrical resistance inside it.
  • a suitable current By applying a suitable current, significant thermal energy is produced by the well-known Joule effect. This heats up the turn and thus welds the contact surfaces between the joint and the ends of the pipes to be joined.
  • the heating procedure, pressurisation and cooling of the pipe ends also requires long processing times and the use of suitable equipment.
  • a further problem of butt welding systems consists of the excessive time to make the connection, whereas from a technological point of view, a difficulty of
  • This model aims at providing a pipe which is pre-fitted with a joint and thus permits a saving on the cost of purchasing the joint or alternatively of the butt welding.
  • Another important aim is that of providing a pipe with which it is possible to obtain a rapid positioning and alignment of the elements to be joined making the presence of specialised operators superfluous.
  • a final aim is that of guaranteeing greater rigidity and bending resistance at the point where the pipes are joined.
  • fig. 1 An assonometric view of a joint obtained by means of the pipe with a socketed end; fig. 2 The same view as figure 1 with the socketed end of the pipe in a
  • fig. 4 An exploded display of the pipe with a socketed end.
  • fig. 5 An assonometric view of a joint obtained with a socket containing a single internal groove.
  • the pipe has one swollen end 1 obtained with a socketing machine.
  • This is a machine that creates a shape in the pipe by means of thermomechanical action performed by a mechanical stopper which creates a swelling of the head by penetrating the end of the heated pipe.
  • the internal surface of the socket 1 has two grooves, the first groove 5 will house a trapezoid section toothed ring 2 which surrounds and squeezes the pipe T to be connected according to the longitudinal thrusts which tend to release the same pipe T.
  • the second groove 6 on the other hand has the job of housing a seal 3 which increases the hydraulic seal between the connected pipes.
  • Grooves 5 and 6 can be of any shape and geometry.
  • the external surface of the socket has a groove 7 in which a ring 4, which has the job of contrasting the radial forces exerted by ring 2, is
  • grooves 5 and 6 on the internal surface of the socket are replaced by a single groove 8 which is used to contain simultaneously both the toothed ring 2 and the seal 3

Abstract

L'invention concerne un modèle de tuyau pré-équipé d'une douille permettant de garantir l'alignement parfait d'un joint et du tuyau auquel il est aplliqué. Ledit modèle permet de construire un tuyau de manière adéquate au niveau de l'une de ses extrémités et de créer une forme interne appropriée pour recevoir des joints d'étanchéité nécessaires pour connecter le tuyau à assembler.
