Definitions

  • the present invention relates to a method for coating a tube with an inner lining, in particular an inner plating.
  • Suitable pipes for such media are steel pipes with an inner coating, an inner lining or an inner plating, which offer cost advantages compared to pipes made of corrosion-resistant steels.
  • Clad steel pipes in particular, which are provided with an inner cladding made of corrosion-resistant steel have been used successfully for the transport of moist and corrosive petroleum and natural gas products.
  • corrosion-resistant steel grades such as 316L, Alloy 825, Alloy 625 or duplex steel grades, which have high strength and good corrosion resistance, serve as the support material (cladding).
  • metallurgically clad pipes which are made from a roll or explosive clad primary material (plates, sheets), from which a pipe is then produced by deformation (rolling, edging) and welding.
  • the steel material and the corrosion-resistant support material are firmly metallurgically connected to each other by a diffusion bridge.
  • Such inner coatings can, for example, be liquid epoxy layers or also multilayer melt coatings in which epoxy resin mixtures are applied in powder form to the inner surface of the heated pipe.
  • organic coatings are relatively corrosion-resistant, their service life is limited in the case of abrasive media that flow through such pipes.
  • the pipe sections are prefabricated and completely coated on the outside at the factory.
  • a three-layer polyolefin (polyethylene or polypropylene) coating (cf. ISO 21809-1) is customary as the coating.
  • the outer surface of the tube must be heated to temperatures between 150 ° C and 250 ° C, because only at these temperatures does the powdered epoxy components melt, mix with each other, react with one another in the desired manner and then react to a so-called gel - Solidify time and finally harden and thus form the basis for the further layer build-up.
  • WO 2014/056107 A1 discloses a method and an apparatus for externally coating pipes. It also addresses the problem that existing coatings should not be damaged during coating. For the solution, an application of uncrosslinked polymers is suggested since these have a lower melting point and should only be crosslinked after application. First, a coating is applied, then the coating is heated and then cooled. The possibility of cooling by water application in the inside of the tube is also mentioned.
  • JP S57 201571 also discloses an apparatus and method for externally coating a pipe, in which the cooling by water injection takes place both on the outside and on the inside. The water cooling takes place away from the local heating of the coating. In addition, it is pointed out that the cooling efficiency is increased by an uncoated inside.
  • US 3,411,933 A describes a device and method in which an outer coating is applied almost over the entire length and the entire inner length is locally cooled. The cooling is time-controlled after the application and fusion of the outer coating.
  • the object is to provide an outer coating process in which the disadvantages mentioned above are at least partially eliminated. Another task can be seen in realizing a corresponding coating system for carrying out such a method.
  • a tube is provided in a coating system.
  • An outer surface area of the tube to be coated is locally heated with a heating device.
  • the inner lining is cooled locally with a cooling device. Heating and cooling are coordinated so that a first limit temperature is not exceeded in a transition zone between the pipe and the lining.
  • the limit temperature is selected so that below this temperature neither the inner lining itself suffers nor the connection between the inner lining (inner tube) and the pipe material (outer tube). This is particularly important for metallic inner linings that have been applied to the inner wall of the pipe using a plating process.
  • This limit temperature represents an essential process variable for the coating itself. It is particularly important in the case of powder coatings which are melted onto the pipe surface, since this temperature is responsible for the required melting and curing process.
  • the heated outer surface area is coated with a coating device.
  • inner lining primarily includes metallic linings, i.e. claddings, made of corrosion-resistant steel qualities such as duplex steels, super duplex steels and alloys such as 316L, Alloy 625, Alloy 825 and copper nickel 9010 (according to relevant material standards and pipe Oil and gas norms / standards: e.g. API 5LD, Saudi Aramco, etc.).
  • inner lining should not be restricted to such linings, but also also to such linings or Coatings include, which are either applied in layers in the lining process, melted or applied in liquid form. These include, for example, liquid epoxy paints, anti-rust paints or other organic coatings, but also so-called three-layer polyolefin coatings with a fusion-bonded epoxy (FBE) primer.
  • FBE fusion-bonded epoxy
  • the first limit temperature is between 40 ° C and 80 ° C. This temperature can also be lower for organic coatings or paints.
  • the second temperature limit that must be reached in order to be able to provide a high-quality outer coating is 150 ° C to 250 ° C.
  • this temperature can also be above or below.
  • the heat conduction is supported by setting a relative feed movement between the tube on the one hand and the heating device, cooling device and / or coating device on the other hand.
  • the pipe to be coated is guided past these devices with a feed movement.
  • This feed movement can be a spiral movement, for example, in which a rotational movement around the pipe axis is combined with a feed movement in the direction of the pipe axis.
  • the feed movement can, however, also be carried out in stages, so that a coating strip is applied during a 360 ° rotation of the tube and then the entire tube is continued by a certain amount, which corresponds to the width of a coating strip.
  • the feed movements can be carried out solely by moving the tube, which is guided past the heating device, the cooling device and the coating device by means of a suitable conveying device.
  • partial movements can also be carried out by the above-mentioned devices themselves.
  • the rotational movement of the tube can be adjusted via a suitable rotating mechanism, while the corresponding translatory movement is carried out via movable unit carriers on the outside of the tube or inside the tube. Movable supports or rails can be provided for this.
  • Suitable cooling fluids are suitable gases or liquids, in particular water, which can be provided in the desired amount and in the desired temperature.
  • gases or gas mixtures has the advantage that they can be used without additional drainage or collecting devices.
  • an air flow is used for cooling minimal effort required and available without additional gas supply. Only the systems for building up pressure and possibly for tempering the cooling air are required.
  • Water cooling may be more efficient, since a higher cooling effect can be achieved with a water flow and the cooling water can easily be discharged through the pipe and returned to a cycle, so that the water consumption can also be kept comparatively low here.
  • control is broad and encompasses not only controls in the narrower sense, but also control processes or regulations in which the desired reference variables are set in feedback.
  • cooling device is arranged on a carrier running inside the tube to be coated. This allows the cooling device to be positioned relative to the coating device and heating device in a simple manner.
  • the cooling device can also be arranged to be movable and / or adjustable on this carrier, so that a relative movement of the cooling device to the tube can also be realized via the movability.
  • the heating device has an induction device, a gas burner device and / or a radiant heat source.
  • An induction device generates eddy currents in the ferritic material of the tube, the energy of which is partly converted into heat by the specific electrical resistance and leads to the heating of the tube.
  • Such a heat source generates the desired heat in a geometrically narrow manner in the range of the magnetic flux precisely specified by induction coils. In this way, a precisely localized supply of heat can take place.
  • the shape of the heat-affected zone (for example round, square, oval) and / or its number and distribution can also be precisely determined using an induction heating device.
  • more or less conventional gas burner devices or other flow or radiant heat sources can also be provided in order to carry out the desired supply of heat or to preheat the material.
  • Radiant heat sources can have radiation surfaces heated electrically or with fossil fuels.
  • the temperature sensor (s) are designed as laser pyrometers allow quick and contactless temperature determination. They can be attached and adjusted at almost any location in order to monitor the temperature at different locations (for example in the area of the heating device, in the area of the cooling device or in the coating area). In this way, temperature profiles can also be determined in critical areas (for example between the heating device and the coating device on the outside of the pipe or between the heating device and the cooling device on the inside of the pipe), in order to ensure that the relevant limit temperatures on the outside are observed precisely of the pipe and in the transition area in the transition zone between pipe and lining. In alternative versions, suitable contact temperature sensors can also be used.
  • the coating system is equipped with a pipe conveyor device for carrying out at least one component of the relative feed movement, in particular a rotational movement.
  • the rotational movement can be carried out, for example, by means of a suitable large-tube turning mechanism with which the rotational movement, which is largely decisive for the coating, can be set to control the coating application.
  • a rotating mechanism receiving the pipe can in turn be made movable in order to carry out the additional longitudinal movement, so that a spiral feed movement (continuous feed) is realized.
  • this longitudinal feed along the tube axis can also take place in stages, that is to say piece by piece with a coating in several rings.
  • the coating system is provided with one or more adjustable device carrier (s) for receiving the heating device, the cooling device, the coating device and / or the temperature sensor for carrying out at least one component of the relative feed movement, in particular a translation movement.
  • the device (s) then moves translationally along the outer or inner surface of the tube (continuously and / or in stages) and thus takes over the execution of a component of the relative feed movement.
  • the tube can be held stationary during the coating process. This makes it easier, for example, to implement a cooling water circuit in conjunction with internal cooling, for which much more compact water collection and circulation devices can then be implemented.
  • a coating system 1 which serves for the outer coating of a tube 2 with an inner coating 3, which is designed here as an inner plating.
  • the pipe 2 is made of an oil and / or gas-compliant steel material (so-called X grades such as X65) and typically has a wall thickness of 12.7 mm to 60 mm and is typically used as a pipeline in the oil and gas production industry.
  • the inner plating is made of an austenitic stainless steel, a duplex steel or a nickel-based alloy with a wall thickness of 2mm to 6mm.
  • the coating system 1 comprises a rotating and conveying system 4, which comprises rotating rollers 5 for rotating the tube, and longitudinal conveying elements 6.
  • the rotating rollers 5 serve to rotate the tube 2 in the circumferential direction about an axis of rotation 7, and the longitudinal conveying elements 6 serve to Perform translation movement along the axis of rotation 7.
  • the turning and conveying system 4 can also be designed as a rotating mechanism arranged on a rail guide, in which the rotating rollers 5 set the tube in rotation and the entire rotating mechanism can be moved along the axis of rotation 7.
  • a coating device 8 For coating the tube 2, a coating device 8 is provided, which uniformly applies a coating material to the outside of the tube 2 along a helical line or a ring line.
  • the helix is generated by the two components 9a and 9b in a relative feed movement.
  • Component 9a designates a rotational component and component 9b a translational component of this relative feed movement of tube 2 to coating device 8.
  • the coating material is applied in powder form and melts on the heated pipe outer surface 2a.
  • a heating device 10 which is used to heat the outer tube surface 2a Inductor is formed and the tube outer surface or tube 2 is heated so far that the desired temperature of 190 ° C in the area of the coating device 8 (second limit temperature T G2 ) is reached and is not fallen below, so that the desired melting process occurs.
  • a cooling device 11 (see Fig. 2 ) is provided, which is arranged on a support 12 projecting into the interior of the tube 2, which sprays cooling water onto the inner surface of the inner coating, so that in a transition zone 14 (cf. Fig. 3 ) a certain limit temperature (first limit temperature T G1 ) of 35 ° C is not exceeded.
  • a temperature sensor 15 which is designed as an infrared pyrometer and detects the surface temperature of the tube in the area of the heating device 10, is used for temperature detection.
  • the carrier 12 is optionally coupled adjustable in the direction of the arrow 16 to a support 17 which comprises an adjustment mechanism which adjusts the carrier 12 in the vertical direction 16.
  • the cooling device 11 is arranged to be pivotable in the direction 18 (also adjustment of the cooling device) about the axis of rotation 7, so that the coolant flow K (cf. Fig. 3 ) is adjustable along the circumferential direction between the heating device and the coating device (see Fig. 2 ). In this way, the local cooling effect can be optimally adjusted.
  • further temperature sensors are provided between the heating device 10 and the coating device 8 for detecting temperatures of the outer surface and / or corresponding sensors for detecting the inner surface temperature (the inner coating 3).
  • the controller 19 controls these parameters such that the second limit temperature T G2 required for coating is reached on the outer surface of the tube 2 and the first limit temperature T G1 in the transition zone 14 between the inner wall of the tube 2 and the inner cladding or Inner coating 3 is not exceeded.
  • a temperature range of 60 ° C to 80 ° C applies to the first limit temperature T G1 in the case of metallic inner cladding and a temperature range of 150 ° C to 250 ° C for the second limit temperature T G1 on the outer tube surface 2a.
  • Fig. 3 shows the detail A from the Fig. 2 together with a temperature wall thickness diagram that shows an exemplary temperature profile over a pipe cross-section.
  • the heating effect H achieves a temperature of T S0 , which is above the second limit temperature T G2 and can be set such that the coating material (for example powder) applied in the coating stream B has a melt 22 on it Coating surface 2a of the tube 2 forms.
