Definitions

  • the invention relates to a method for coating metallic pipes or other long components of limited cross-section, in particular of tubes for heat exchangers, and to an apparatus for carrying out this method.
  • modified PTFE materials that have properties similar to PFA in the area of acid resistance do not have a melting point in contrast to PFA. For this reason, they can not be melt-extruded processed but only paste-extruded. That is, the material is not fused (as in PFA) but pressed together only in pasty form, which amounts to a sintering.
  • the molecules align only longitudinally to the extrusion direction, although a relatively high strength in the longitudinal direction, in the transverse direction, the creep rupture strength is relatively low.
  • the material has a high cold flow property. That is, the material flows away under pressure over time. Unfortunately, this process can not be stopped so that leaks occur again and again at the sealing points of the hoses in the tubesheets. Otherwise, the same problems apply as with the PFA.
  • Chrome-nickel material "A59” is almost acid-resistant. However, even after a short period of operation, its smooth surface during production changes. The surface becomes rough and thus very susceptible to dirt, which can lead to the blocking of the flue gases. However, since "A59” has a high strength, pipes with a larger diameter can be used, which in turn partially counteracts the contamination. The biggest disadvantage of the "A59", however, is the high price. The costs for a heat exchanger of the same power are about twice as high for the "A59” as for the PFA.
  • the invention is therefore based on the object mentioned above and described in more detail above method and a corresponding device for coating of metallic components and further develop that even relatively long components can be mechanically coated under temporally and economically optimal conditions. In particular, it should be possible to continuously coat the components.
  • a corresponding device for carrying out the method achieves the object according to the invention by a first processing line with a first drive, a first preheater, a device for applying the primer layer and at least one oven for curing and drying and a second processing line with a second drive, a second preheater , an extruder with a crosshead for applying the coating, an induction furnace and a curing oven.
  • tube When the term "tube” is referred to in the following, it is intended to encompass all possible components to be coated whose length exceeds the extent and the cross section by a multiple. Since the coating takes place from the outside, the tubes or other hollow components can also be closed on one side.
  • the first and second processing line are operated separately.
  • the separate embodiment will generally be the preferred one, since on the one hand the length of the processing lines otherwise becomes relatively large and it is possible by the division to perform the coating with adhesive primer and the later actual fluoroplastic coating at different times and at different locations.
  • the standstill of a line does not immediately stop the entire system.
  • a further embodiment of the invention provides that the pipes to be coated are connected before each processing line with suitable pipe connection elements and the treatment process proceeds continuously. In this way, so to speak, it is possible to coat "endless" components, which is particularly expedient from an economic point of view.
  • the components to be treated are to be degreased before being fed into the first processing line and / or sandblasted in order to ensure a secure connection between primer layer and component. If “sandblasting” is mentioned here, this also means the irradiation with corundum, glass bodies or the like.
  • the tube is transported not only axially in the first processing line, but at the same time about its longitudinal axis rotated so that its surface undergoes a sense of a helical movement.
  • the application of the primer layer can be carried out by spraying, wherein the range of spraying in the axial direction can be relatively short, when the rotational speed is adjusted in relation to the feed speed accordingly.
  • the adhesive primer is so to speak "helical" applied to the component to be coated.
  • the preheating of the component in the first processing line is effected by means of hot air.
  • a preheated tube allows better primer-to-tube contact when applying the primer layer, which is essential for even coating.
  • Another teaching of the invention provides that the preheating of the component takes place in the second processing line by means of hot air. Preheating is of particular importance here since the fluoroplastic applied in liquid form in the extruder would otherwise crosslink prematurely on the cold metal surface of the component and, in extreme cases, even lead to dripping of the fluoroplastic after leaving the extruder crosshead. Of course, the preheating can also be done by other suitable measures.
  • Another preferred embodiment of the invention provides that the application of the primer layer and the coating in the extruder are each carried out in a single operation. This is for an economic continuous manufacturing operation of particular interest. Attention must be paid to the application and drying process, so that the layer thickness on the component to be coated is the same everywhere. For example, when the primer is applied to a pipe, no "seams" may occur due to too thick or too thin "coating boundary lines".
  • the curing of the coated component takes place in an oven. In this way, it is ensured that a uniform curing of the fluoroplastic layer is made possible.
  • the organic fluoropolymers PFA (perfluoropropyl vinyl ether) or MFA (perfluoromethyl vinyl ether) are preferably used for the coating.
  • the first drive of the first processing line is provided with a rotary feed device.
  • This rotary feed device can be controlled so that axial and rotational movements can be influenced individually in order to allow optimum adaptation to the width of the application zone of the adhesion prime.
  • a spray nozzle is used to apply the adhesive primer layer, which is formed in an advantageous embodiment of the invention as a broad jet nozzle, which extends substantially parallel to the tube longitudinal axis.
  • An arbitrarily long tube 1 preferably made of steel, lies on a roller conveyor 2 and is advanced in rotation by a special rotary feed 3.
  • An endlessly long tube 1 is formed by fastening a tube to the next one by means of connecting elements in order to achieve a continuous process.
  • the rotation of the tube 1 is in a certain ratio to the feed. This ratio is diameter dependent.
  • a tube preheating 4 is switched to preheat the tube, preferably with a hot air blower 5 to a primer specific temperature.
  • a developed spray device 6 After preheating a developed spray device 6 is installed. In cooperation of the tube preheating 4 and spray device 6, it is possible to apply a uniform primer layer with the predetermined layer thickness on the rotating tube 1 in a single operation.
  • the tube 1 is driven by the rotary feed 3 through a drying oven 7, whose length is sized is that it ensures the predetermined residence time in the drying oven 7 in connection with the feed.
  • This residence time must be strictly adhered to in order to complete the polarization, that is to say the connection of the primer to the steel tube 1.
  • the volatiles must be completely expelled from the primer to prevent subsequent blistering in the PFA coating. It must be ensured that the drying takes place uniformly over the layer thickness. If, for example, the outer layer is dried first, microcracks occur in the layer since the residual moisture from the inner layers can no longer escape and therefore ruptures the already dried outer layer.
  • the drying oven 7 is then followed by a polarizing oven 8, in which the polarization, ie the combination of adhesive primer and steel tube 1 takes place.
  • the drying and polarization temperature in the oven 7 and 8 must be chosen and ensured so that, although the polarization temperature is reached and maintained over the full length of the furnaces, the polymerization temperature through which the subsequent connection between primer and PFA or MFA , but not reached.
  • the primer coating is completed. Behind the furnaces 7, 8 then provided with the adhesive primer tube 1 'can be removed and optionally separated. It goes without saying that the ovens 7 and 8, which are shown individually in the exemplary embodiment shown and preferred so far, can also be realized as a common structural unit.
  • a similar line is installed for the second coating with PFA or MFA.
  • the previously coated with primer tube 1 ' is again placed on a roller conveyor 10 and advanced by means of a belt withdrawal 11 at a constant speed.
  • the individual fluoropolymer layers are not applied successively as usual, but are melted by means of an extruder 14 with a crosshead (not shown) in a single operation.
  • the pipe 1' is preheated by means of a special device 12, whereby it must be ensured that the polymerization temperature is not reached.
  • the melt PFA or MFA is then melted in full thickness in one operation on the tube 1 '.
  • the tube 1 ' is heated by induction heat in an induction furnace 15 far above the polymerization. This ensures the connection of primer PFA (or MFA).
  • the furnace length is directly related to the pipe feed.
  • the now coated tube 1 is cooled and driven over a roller conveyor (not shown) for further use.
  • the individual tubes are plugged together with connectors so that an infinitely long tube 1 'is formed and can be coated without interruption.
  • an acid-resistant tube 1 of any length, which is given both by the applied PFA (or MFA) layer and by the acid-resistant primer.
  • Primer and PFA / MFA can not be infiltrated and detached by corrosion products
  • the pressure-resistant support tube can handle temperatures and pressures of any size, and the diameter of the pipes can be chosen as required by the overall process of the power plant it is possible to bend the tubes coated with the method according to the invention, for example coated U-tubes, such as those used in heat exchangers, can be produced.
