Definitions

  • the invention relates to a method for the production of condenser or method for the production of condenser or heat exchanger tube plates / tubes plates, wherein a base material is used, which is connected to a support material.
  • the condenser or heat exchanger tube plates / tubes plates are therefore provided with a sufficient corrosion protection against these cooling media, which is done by plates, which are used as tubesheet or tube plate, is plated with a support material made of titanium or austenitic materials, the Pad material forms the appropriate corrosion protection.
  • the support material must have sufficient adhesion with the base material. Furthermore, a fast and rapid production of the pipes should be possible.
  • the object of the invention is to provide a cost-effective production process.
  • This object is achieved by a method for the production of condenser or heat exchanger tube plates / tubes plates, wherein a base material is used, which is connected to a support material, wherein the support material is glued with an adhesive on the base material.
  • the invention is therefore based on the idea no longer to use the elaborate explosive cladding, but to stick the support material with the aid of suitable adhesives on the base material. An explosive plating would thus be completely eliminated. Bonding would result in cost advantages of more than 50%. Another advantage of the bonding method over explosive cladding is that shorter production times are possible since the complex measures for explosive cladding are eliminated. Furthermore, there are fewer security risks in bonding compared to the high security risks associated with handling explosives.
  • the adhesive is applied with a brush, a roller or a spatula.
  • the adhesive is applied on one side either only on the base material or only on the support material.
  • a comparatively fast production is possible because the adhesive has to be applied only on one side.
  • an adhesive based on epoxy resin is used. Measurements and tests have shown that an optimal connection between the base material and the cladding material is possible through the use of epoxy resin as adhesive.
  • the base material is sheet metal and the support material is titanium or an austenitic material. Especially this combination leads to an excellent protection against corrosion when used in aggressive or corrosive cooling media.
  • a base material 1 is first arranged and possibly fixed in place by means of devices.
  • a support material 2 is arranged above the base material 1 in a suitable manner in a next process step.
  • a slight gap 4 is between the support material 2 and the base material 1 between the support material 2 and the base material 1 between the support material 2 and the base material 1 between the support material 2 and the base material 1 between the support material 2 and the base material 1 between the support material 2 and the base material 1 a slight gap 4, wherein in the illustration according to FIG. 1 the gap 4 is exaggerated strong.
  • an explosive charge which is formed as a loose bed, is applied locally in the vicinity of the support material 2 in a suitable manner.
  • a detonation which are symbolized by detonation arrows 5
  • the disadvantage here is that the surface is formed by possibly occurring forces inhomogeneities wavy.
  • the method according to the invention is characterized in that an adhesive 3 which is produced on the basis of epoxy resins is used.
  • the base material 1 is fixed in a stationary manner in a first method step and provided with the adhesive 3.
  • the support material 2 can be fixed in place and provided with the adhesive 3.
  • the application of the adhesive 3 by means of a brush, a roller or a spatula. The application should be such that the density distribution of the adhesive 3 on the surface of the base material 1 and the support material 2 is uniform.
  • the base material 1 is bonded together with the support material 2, wherein at the beginning of the curing time of the adhesive 3 of the base material 1 relative to the support material 2 can be moved, thus allowing alignment of the two materials.
  • the hardening time of the adhesive 3 is the time in which the adhesive 3 by chemical processes, the base material 1 with the support material 2 mechanically / physically (adhesively) connects. After the curing time of the adhesive 3 is usually cured and a displacement of the base material 1 relative to the support material 2 is then no longer possible.
  • a sheet is used as the base material 1.
  • a support material 2 titanium or austenitic material is used as a support material 2 titanium or austenitic material is used. The support material 2 is exposed during operation aggressive and corrosive fluid media.
  • FIG. 2 is a cross-sectional view of a heat exchanger tube bottom / tube plate (6) can be seen.
  • the heat exchanger tube plates / tubes plates are pierced by means of condenser or heat exchanger tubes (9) at puncture points (7) and thus create a fluidic connection between a cooling water chamber (8) and the interior of the condenser or heat exchanger tubes (9).
  • the condenser or heat exchanger tubes (9) are firmly connected to the heat exchanger tube plates / tube plates.
