Definitions
- the present invention relates to a method for coating a pipe with an interior lining, in particular an interior cladding.
- Suitable tubes for such media are steel tubes with an inner coating, an inner lining or an inner cladding, which offer cost advantages over tubes made of corrosion-resistant steels.
- plated steel pipes provided with an inner cladding of a corrosion resistant steel are successfully used for the transportation of wet and corrosive petroleum and natural gas products.
- Corrosion-resistant steel grades such as 316L, Alloy 825, Alloy 625 or even duplex steel grades with high strength and good corrosion resistance are used as the cladding material (cladding).
- blast-plated starting material plates, sheets
- deformation W alzen, edges
- welding a tube is made.
- the steel material and the corrosion-resistant support material are firmly metallurgically bonded together by a diffusion bridge.
- Such inner coatings may be, for example, liquid-applied epoxy layers or else multilayer melt coatings in which epoxy resin mixtures in powder form are applied to the inner surface of the heated tube.
- organic coatings are relatively resistant to corrosion, their lifetime is limited in abrasive media flowing through such pipes.
- the pipe sections are prefabricated and externally completely coated at the factory.
- the coating used is a three-layer polyolefin (polyethylene or polypropylene) coating (cf ISO 21809-1).
- the outer surface of the tube must be heated to temperatures between 150 ° C and 250 ° C, because only at these temperatures, the powdered epoxy components go into a melt, mix with each other, react in the desired manner with each other and then after a so-called gel Solidify and finally harden and thus form the basis for the further layer structure.
- the tubes are passed through annular induction coils that heat a complete tube section.
- Organic interior coatings usually do not withstand such temperatures.
- plated pipes and in particular mechanically clad pipes are also only limited suitable for such a preparatory heat treatment, as affected by the different thermal expansion coefficients of the outer tubes (carbon-manganese steel material) and the inner tubes (corrosion-resistant steel quality), the connection between the tubes or even can be completely solved.
- the best practices for thermally assisted application of durable exterior coatings for such pipes can not be used and, if necessary, less resistant external coating systems must be used.
- the object is to provide an outer coating method in which the abovementioned disadvantages are at least partially eliminated. Another object can be seen to realize a corresponding coating system for carrying out such a method.
- the present invention provides a method for exterior coating a pipe with an inner coating, in particular an inner plating, comprising:
- a second aspect of the present invention relates to a coating installation for carrying out the method according to the invention, which comprises:
- FIG. 1 is a schematic representation of a coating system according to the invention
- Fig. 3 is an enlarged sectional view of a pipe to be coated (detail A of Fig. 2) with a schematic representation of a temperature profile over the pipe wall cross section and
- FIG. 4 shows a schematic representation of a method according to the invention for pipe coating.
- a tube is provided in a coating installation.
- An outside surface area of the pipe to be coated is locally heated with a heater.
- 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 chosen so that below this temperature neither the inner lining suffers nor the connection between the inner lining (inner tube) and pipe material (outer tube). This is particularly important for metallic inner linings that have been applied to the inner wall of the tube in a plating process.
- the local heating and the local cooling are coordinated so that a second limit temperature is not undershot in the (heated) outer surface area to be coated.
- This limit temperature is an essential process parameter for the coating itself. It is particularly important in powder coatings that are melted onto the pipe surface, as this temperature is responsible for the required melting and curing process.
- the coating of the heated outer surface area is effected with a coating device.
- inner liner covers primarily metallic linings, ie claddings, of corrosion-resistant steel grades such as duplex steels, super-duplex steels and alloys such as 316L, Alloy 625, Alloy 825 and cupronickel 9010 (in accordance with relevant material standards and piping standards). Oil and gas standards / standards: eg API 5LD, Saudi Aramco, etc.)
- inner lining should not be limited to such linings in the context of the present application, but also such linings or Coatings which are either applied in sheets by lining, melted or applied liquid.
- the first limit temperature is between 40 ° C and 80 ° C.
- this temperature may also be lower.
- the second limit temperature which must be reached in order to provide a high quality outer coating is 150 ° C to 250 ° C.
- this temperature may also be higher or lower.
- the tube to be coated is guided past these above-mentioned devices by means of a feed movement.
- This feed movement can be, for example, a spiral movement in which a rotational movement about the tube axis is combined with a feed movement in the direction of the tube axis.
- the feed movement can also be carried out step by step, 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 advancing 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.
- a suitable conveying device In other embodiments, but also partial movements of the above devices themselves can be performed.
- the rotational movement of the tube can be adjusted via a suitable slewing gear, while the corresponding translational movement is carried out by means of movable aggregate carriers on the outside of the tube or in the interior of the tube.
- movable supports or rails can be provided.
- Suitable cooling fluid are suitable gases or liquids, in particular water, which can be provided in the desired amount and at the desired temperature.
- gases or gas mixtures has the advantage that they can be used without additional outflow or collecting devices.
- an air flow is for cooling with Minimal effort available and available without additional gas supply.
- a water cooling is possibly more efficient, since with a water flow, a higher cooling effect can be achieved and the cooling water can be easily removed through the pipe and recycled into a cycle, so that here too the water consumption can be kept relatively low.
- control in this context is broad and includes not only controls in the strict sense, but also control operations or regulations in which the desired reference variables are set fed back.
- the controller is designed and set up in such a way that it selectively detects, adjusts and possibly changes individual or any combinations of the following parameters:
- cooling device is arranged on a running inside the pipe to be coated carrier.
- the cooling device may also be arranged to be movable and / or adjustable on this support, so that a relative movement of the cooling device to the pipe can be realized via the movability.
- an adjusting device is provided on the cooling device, via which the position and / or an orientation of the cooling device are adjustable. This further improves the setting options of the cooling device and thus an improvement of the cooling parameters.
- 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 partially converted into heat by the specific electrical resistance and leads to heating of the tube.
- Such a heat source generates the desired heat in a geometrically tight manner in the region of the magnetic flux precisely predetermined by induction coils. In this way, a precisely localized heat supply can take place.
- the shape of the heat affected zone for example, round, angular, oval
- / or their number and distribution can be accurately determined with an inductively operating heater.
- Radiation heat sources may have electrically or with fossil fuels heated radiant surfaces.
- Embodiments in which the temperature sensor (s) are designed as laser pyrometers permit rapid and non-contact temperature determination. They can be mounted and adjusted in almost any location to monitor the temperature in different locations (for example, in the area of the heater, in the area of the cooler or in the coating area). In this way, temperature profiles can also be determined in critical regions (for example between the heating device and the coating device on the outside of the device)
- the coating installation is equipped with a pipe conveying 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, via a suitable large-diameter rotary mechanism, with which the rotational movement largely controlling the coating for controlling the coating application can be set.
- a pipe receiving slewing can in turn be made movable again to perform the additional longitudinal movement, so that a spiral feed movement (continuous feed) is realized.
- this longitudinal feed along the tube axis can also be done in stages, ie piece by piece in a coating in several rings.
- the coating system is provided with one or more adjustable device carriers 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 translational movement.
- the device (s) then move translationally along the outer or inner surface of the tube (continuously and / or in stages), thus assuming the execution of a component of relative feed motion.
- the tube may be received stationary. This facilitates, for example, the realization of a cooling water circuit in conjunction with the internal cooling, for which substantially more compact water collecting and circulating devices can be realized.
- FIGS. 1 and 2 show an embodiment of a coating system 1 according to the invention, which is used for the outer coating of a tube 2 with an inner coating 3, which is designed here as an inner cladding.
- the tube 2 is made of an oil and / or gas-conforming steel material (so-called X-grades such as X65) and typically has one

- the internal cladding is made of an austenitic stainless steel, a duplex steel or a nickel-based alloy in a wall thickness of 2mm to 6mm.
- the coating installation 1 comprises a turning and conveying system 4, which comprises rotating rollers 5 for rotating the tube, as well as 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 this purpose to perform a translational movement along the axis of rotation 7.
- the rotating and conveying system 4 can also be designed as arranged on a rail guide slewing in which the rotary rollers 5 enable the tube in rotation and the entire rotating mechanism along the axis of rotation 7 can be moved.
- 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 helix or a ring line.
- the helix is generated by the two components 9a and 9b in a relative feed motion.
- the component 9a designates a rotational component and the component 9b a translation component of this relative advancing movement of the tube 2 to the coating device 8.
- the coating material is applied in powder form and fuses on the heated tube outer surface 2a.
- a heater 10 which serves as Inductor is formed and the pipe outer surface or the tube 2 heats up so far that the desired temperature of 190 ° C in the region of the coating device 8 (second limit temperature TG2) is reached and not fallen below, so that the desired reflow occurs.
- a cooling device 11 (see FIG. 2) is provided inside the tube, which is arranged on a carrier 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 TGI) of 35 ° C is not exceeded.
- first limit temperature TGI first limit temperature
- a temperature sensor 15 which is designed as an infrared pyrometer and detects the surface temperature of the tube in the region of the heater 10.
- the carrier 12 is optionally coupled in the direction of arrow 16 adjustably with a support 17, which comprises an adjusting mechanism which adjusts the carrier 12 in the vertical direction 16.
- the cooling device 11 is arranged pivotable in the direction 18 (also adjustment of the cooling device) about the rotation axis 7, so that the coolant flow K (see 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).
- a controller 19 is provided, which via signal and control lines 20 with the rotating and conveying system 4, the adjustment of the support 17, the heater 10, the coating device 8, the temperature sensor 15 and (not shown) of the cooling device 11 is coupled.
- the controller 19 adjusts (or controls) one or more of the following parameters:
- the controller 19 controls and regulates these parameters so that the required for coating second boundary temperature T G2 is achieved on the outer surface of the tube 2 and the first limit temperature TGI in the transition zone 14 between the inner wall of the tube 2 and the
- a temperature range from 60 ° C. to 80 ° C. applies to metallic interior plating and a temperature range from 150 ° C. to 250 ° C. for the second limit temperature TGI at the pipe outer surface 2 a.
- FIG. 3 shows the detail A from FIG. 2 together with a temperature-wall-thickness diagram, which shows an exemplary temperature profile over a pipe cross-section.
- a temperature of Tso which is above the second limit temperature T G2 and is adjustable so that the coating material applied in the coating B (for example, powder) a melt 22 at the Coating surface 2a of the tube 2 forms.
- the relative feed movement shown here is decisively formed here by the rotational component 9a.
- On the opposite side of the coolant flow K strikes the inner surface 3a of the inner coating 3, in a range between the local heat flow H (heated area) and the coating stream B.
- the adjustability in this area is indicated by the arrow 18.
- the coolant flow K causes the temperature in the direction of the pipe inner wall 3 a to decrease so much that the temperature in the transition zone 14, which is formed around the interface 23 between pipe inside and lining, is lowered below the limit temperature TGI, so that at the interface itself Interface temperature T S G prevails. It is assumed here that the thermal conductivity in the pipe 2 is higher than that in the lining or inner coating 3.
- different limit temperatures TGI may also be required, which optionally can be selected and set via the controller 19.
- the second limit temperature TG2 on the outer surface of the tube is determined primarily by the heating effect H, while the first limit temperature TGI is adjustable primarily by the cooling effect K.
- FIG. 4 shows schematically a method according to the invention for coating the outside of the tube 2, comprising the following steps:

- Life Sciences & Earth Sciences (AREA)
- Wood Science & Technology (AREA)
