Definitions

  • the invention relates, on the one hand, to a closed tank, in particular to a water heater with internal protection against a liquid or gaseous fluid, and, on the other hand, to a method allowing this internal protection of the tank to be produced.
  • the present invention aims to remedy these drawbacks.
  • the invention as characterized in the claims, solves the problem of creating a closed reservoir, in particular of a heater with a process by which two metallic enantiomorphic half-shells are taken, the internal surface of these two half-shells is prepared to make it suitable for receiving metallization , an adequate thickness of aluminum or zinc is applied by metallization to this prepared surface, then the two half-shells are assembled by welding to obtain the reservoir and, finally, the latter is subjected to a heat treatment to temperature given to improve the anti-corrosion effect of the internal coating, this tank comprising a metal support, preferably of steel, the internal surface of which is provided with a protective coating of aluminum or zinc applied by metallization and then subjected to a heat treatment.
  • the advantages obtained thanks to this invention essentially consist in that the coating of the internal surface of the tank is applied before its assembly, which allows to have an easy access to all this internal surface and to be able to control the uniformity of the coating and check that the entire internal surface is covered with the protective coating. Therefore, the tanks have an internal surface provided with effective, real and long-lasting protection.
  • Figure 1 shows, in elevational view in section, two half-shells of a tank according to the invention before its assembly.
  • the reservoir comprises a metal support preferably made of steel and formed of two half-shells 1, 2 whose shape and section are arbitrary.
  • the reservoir may be formed of a container which can be closed by a cover.
  • the tank consists of a cylinder closed at each end by a bottom.
  • the invention recommends using two half-shells 1, 2 each of which is formed by a ferrule 3, 4 and a base 5, 6. These two half-shells 1, 2 will be assembled after application of the protective coating, by welding the edges 7, 8 of the two ferrules 3, 4 together.
  • an anti-corrosion protective coating 11, 12 is produced on the internal surface 9, 10 of each half-shell 1, 2.
  • the invention provides a process which can be carried out because the two half-shells 1, 2 are independent before the coating 11, 12 and that the latter can be applied from the open end 13, 14 of the ferrules 3, 4.
  • the internal surface 9, 10 is prepared to make the latter suitable for receiving metallization.
  • a metal layer is applied by metallization having an adequate thickness of aluminum, zinc or other similar products.
  • the two half-shells 1, 2 are welded by applying their edges 7, 8 against each other.
  • the tank obtained is subjected to a heat treatment at a given temperature. During this heat treatment, the different aluminum, zinc or other molecules are welded to each other. As a result, a homogeneous layer is obtained and the anti-corrosion effect of this internal coating is improved.
