Definitions

  • preheating of a large part of the tube is carried out before the installation of the coating complex.
  • a large part of the tube is circumferentially preheated either in a gas oven or by electrical induction during the rotation of the tube going to receive, by helical winding, a thin film of glue (generally called primary) and one or more constitutive thermoplastic films of the coating.
  • glue generally called primary
  • This complex can also be installed in one or more operations.
  • the adhesive film is in contact with the metal and responsible for the adhesion of the thermoplastic coating to the metal support.
  • the device for carrying out the hot coating of metalli ⁇ cal tubes by means of thermoplastic ribbon materials comprising means for axially advancing the tube to be coated and for rotating it around its axis, means for heating the tube during its movement and at least one extruder delivering a thermoplastic tape of determined width which is wound as the tube is characterized in that the heating means of the tube are arranged to heat an area limited thereof, in relation to the width of the ribbon, these means being arranged upstream and close to the extruder.
  • Figure 1 is a schematic end view of the installation in operation
  • Figure 3 is a perspective diagram of a fragment of coated tube.
  • the heating means 4 are placed at a distance close enough to the adhesive tape 3 so that the surface temperature of the tube remains compatible with the hot adhesion of the plastic.
  • the heating means 4 can be advantageously of the induction type, the radiating element of rectangular outline being placed at a small but adjustable distance from the wall of the tube 1.
  • the tangential speed of the tube 1 can be equal to 45 m / min.
  • the speed of transla ⁇ tion of the tube 1 along its axis can be equal to 200 mm / tou Under these conditions, 9 m 2 of the tube 1 is covered per minute.
  • the evolution curves of the temperature Q (° C) are obtained as a function of the time t (sec.) And the length (1) traveled in mm, shown in the figure. 6.
