Description

CNC-supported production of winding components

The invention relates to a method for processing and joining of

Composite winding components in the form of component components for corrosive media with large tolerances.

The plant engineering for chemistry, metal extraction and processing, power plants,

Waste incineration plants and water technology is characterized by project business. Most of them require containers in the form of storage, process and special containers, and apparatus in the form of columns, scrubbers, evaporators, electrostatic precipitators, centrifuges, filter housings and many other applications, as well as simple tubes for chimneys, chimney liners and gas channels as well as complex special constructions for Pipe distributors are individually designed and constructed statically. As a result, the components to be produced are possibly produced in small batches (ETO = engineering to order).

At high corrosion stress and temperatures up to approx. 150 degrees as well

Pressing up to about 10 bar (+/- 5 bar), composite materials are used to build

Containers and apparatus used. The lengths or heights of such containers range from up to 25 meters with a diameter of up to eight meters. These are the usual still transportable sizes that are produced within a plant. Because of static and manufacturing advantages, most components are, as far as a cylindrical shape, produced in the winding process, due to corrosive media, the inner surface of either a thermoplastic material (liner) or a chemical protection layer (CSS) exist.

For the lining of containers exist in principle two variants. A first variant is based on a static load-bearing construction and is first completely prefabricated and prepared for subsequent lining. Then the lining and winding is done according to one of the possible methods: laminate lining, flake coating, rubber coating, glued and welded thermoplastic liners,

CONFIRMATION COPY Fixed point lining with foils, spray coatings, rotolining or isostatic pressing. Here, the liner thickness is not relevant for the production of the supporting structures, as it is done later and adapts to this supporting structure in certain tolerances. The advantage of this method is no edge offset, as far as several parts of the apparatus or container must be joined together.

Alternatively, it is possible to first manufacture the lining (liner or the chemical protection layer) or first to join it during the assembly of the components, whereby only a slight edge offset may occur during subsequent joining during assembly. The use of composites with CSS can usually be used for all high-quality blunt constructions. The allowable edge offset is often <1/3 of the liner thickness and leads to effects for all possible tolerances.

Based on the principles and implementation details of DIN 13121-3, one can differentiate between the following manufacturing processes during assembly and winding processes:

1. winding prefabricated component body

The production of such a container takes place in composite with thermoplastic lining by prefabricated floors, nozzles, manholes, rectangular connections, apparatus, flanges, etc., wherein the thermally formed liner elements are welded together. Subsequently, a lamination or fibers are sprayed on until the required final thickness is reached. Subsequently, the

Trimmed container and if necessary used neck, if necessary. The individual cylinder shots are prepared to the extent that they can then be assembled, the liners are welded. The assembly takes place in such a way that the upper floor is suspended and lifted on a crane and the first cylinder section (liner shot) is placed underneath. After the seam has been prepared, welded and deposited in a conductive, abraded and prelaminated state, further cylinder sections are set or the lower floor below

pushed, adjusted and connected in the same way. Subsequently, the winding process takes place, wherein winding crosses at the bottom of the assembled component body is laminated and then carried out by grinding the prelaminate of the cylinder, the winding of the cylinder to the required final thickness. If necessary, prefabricated nozzles or manholes etc. are retrofitted. The same applies to the cultivation of lifting eyes, brackets, e.g. for ladders, platforms or swivel arms or cores for stiffening ribs, which may need to be attached externally to the body. All operations to be carried out subsequently generally have to be carried out manually, in chronological order: marking, drilling or sawing, milling, grinding, welding, sparking,

Grinding and grinding as well as positioning for or during joining and laminating. Sanding here is understood to mean the transition to the already applied laminate in order then to perform an overlaminate. in the

Following this, an outer layer can be applied.

As far as a composite with a chemical protection layer (CSS) is used, a similar process has to be used whereby the individual prepared components are joined together by joining and pre-reinforced CSS, instead of welding and pre-reinforcing the thermoplastic cylinder sections.

2. Free arm winding technique

The production of a composite component with a chemical protection layer (CSS) is again carried out by prefabricating the trays, with or without the incorporation of e.g. Stub and then clamping of a floor on the free end of a winding device.

The further assembly takes place on the winding form usually with a

Memory core with a circumferentially variable sheath, which is mounted on a rotating axis mounted on one side. This is a floor first stretched the free end of the winding shape and sanded the bottom end. A cylinder is then added, applying the chemical protective coating (CSS) and awaiting the reaction before the reinforcement is sanded and applied. In the cylinders themselves, a reinforcing laminate is wound over the bottom end to make the connections between the cylinder and the bottom element, winding up to the required final thickness. Following this, an outer layer can be applied.

As far as the cylinder of the winding shape is very short, two halves of the required composite winding component can be made separately and joined together in the middle. This is done by adjusting, Anschäften and grinding, in which case the Chemieschutzschicht then produced and an overlaminate is applied. Subsequently, an outer layer can be applied, if necessary.

If the cylinder of the winding shape is long enough, pull the prefabricated part, that is, the bottom with cylinder, from the winding shape and then lifts it using a crane in the vertical. The second floor can be slid underneath and both parts joined together by fitting, stitching, sanding and making the chemical protective layer as well as the overlaminate.

Optionally, an outer layer can also be applied in this case.

If a composite material is used with a thermoplastic lining, a clamping takes place from a bottom to the free end of a core of the winding device, which can be followed by welding and reinforcement of the cylinder sections (cylindrical locks) on the winding shape and the core is gradually pulled out. For shorter designs, a core of appropriate length can be used. Subsequently, the composite component is removed from the core and closed with a bottom part. Even after completion of this operation, it is again necessary to prepare nozzles, manholes, etc. manually, in turn, the preparatory work consist of marking, drilling or sawing, milling, grinding and grinding and positioning to or during the joining.

In both manufacturing processes there is a need for the lining (liner or CSS) usually including pre-laminate and often also with the structural or

Traglaminat marked, drilled or sawed, cut, chamfered, milled, sanded or sanded. For this purpose, the usual methods using measuring instruments, drills, jigsaws, knives, angle or finger grinders are used.

When using a composite with chemical protection layer (CSS) also the bottoms, nozzles, manholes, rectangular connections and apparatus flanges are prefabricated. The chemical protective layer is in this case by lamination and

Fiber spraying applied to the floors, usually in turn to the required final thickness. After trimming, stubs may optionally be used by drilling and grinding and producing the chemical protective layer and a bonding laminate. Following this, the outer layer is wound.

For both alternatives shown also applies that the nozzle in the cylinder and possibly also in the soil by drilling, grinding and manufacturing the

Chemical protective layer and the compound laminate can be used. The same applies to the attachment of brackets for attachments.

The manufacture of the plastic components, in particular the composite winding components, is subject to the external boundary conditions of a chemical resistance, the use of a composite material with liner or CSS and a small volume production after order entry (engineering to order, ETO). Here are a variety of manufacturing variants conceivable, which indeed offer the potential for systematization, but with respect to a CAD / CAM-based automation in the manufacturing process one Face a series of problems. The linings used are, for example, very thin; both thermoplastic cylinder sections (liners) and chemical protective layers (CSS) must be in very good fitting together with high-quality products at all joints without serious weakening of the thickness in the joining zones. The reinforcement or structure laminates have very high manufacturing variations in thickness, which is why external contours are not suitable for reference. The inner dimensions of the component body, namely the diameter, the length and height and the waviness and possibly also a prepared nozzle, in particular with a larger diameter for

Manholes and gas inlets have tolerances that are typically larger, often significantly larger than the liner thicknesses.

In addition, a shrinkage process takes place when curing composite materials. As far as resin-based manufacturing is concerned, it should be noted that unsaturated polyester resins shrink more than vinyl ester resins. The scum process is further influenced by additives, namely reaction start and reaction rate, and peak temperature. Although these can be set in certain bandwidths, they have a lasting effect on the shrinkage process. As far as glass is used to build the components, it should be noted that glass does not shrink and the higher the glass content, the lower the

Shrinkage will be. As far as fillers are used, they too can reduce the shrinkage process, as they themselves do not shrink and possibly influence the course of the reaction. For prefabrication of the floors is to be noted further that the negative molds are subject to manufacturing tolerances, which are based on the

Transfer composite soil. The negative molds for cylinders are also subject to manufacturing tolerances that are transmitted to the composite floor, which leads to the conclusion that high-precision shapes for ETO standard quantities are not profitable or often associated with weights that are conventional

Free arm winders are not suitable. As far as larger components to be installed, such as manholes, gas connections, etc. to be used, is to Note that the larger the components, the more serious are the tolerances with respect to the always the same thin chemical protection layer.

When using composite with a thermoplastic lining (liner), the influences for CSS constructions should also be considered. In principle, similar influences apply as in the aforementioned method. In addition, however, it should be noted that the liners are usually welded and then thermoformed. During forming, residual stresses from the production of the liners are released. The shrinkage process depends, among other things, on the liner, the forming temperature, the cooling conditions, the time of demolding and on the method and the beginning of the solidification. For cylinders, on the other hand, the circumference from the liner of the cylinder to the circumference of the trimmed liner end may change even at small diameters.

Due to the aforementioned problems, CAD / CAM-based setpoint specifications were not directly usable within an automation, because CSS or liners can not be designed accurately enough and deviate from the specified nominal dimensions.

The present invention has for its object to provide a novel method which eliminates the existing problems of the previous manufacturing processes and ensures an at least partially automated production of composite winding components with high quality assurance.

For solving a method for processing and joining of plastic components, in particular composite winding components for corrosive media in the form of component components is proposed, which comprises at least the following steps:

Providing at least partially prefabricated component components, providing CAD / CAM setpoint specifications,

Implementation of a CNC-supported bearing detection in the area of the joining zones of the components to be joined, Determination of actual coordinates of reference surfaces, cut edges, lines or at least points of the component components in the region of their joining zones,

Performing at least one first machining operation in the region of the joining zones on the basis of the CAD / CAM setpoint specifications revised by means of actual coordinates and exact positioning of the component components to be joined for further processing.

Further advantageous embodiments of the invention will become apparent from the dependent claims.

By means of the method according to the invention, an automated method for processing plastic components, in particular composite winding components for corrosive media is demonstrated using CAD / CAM setpoint specifications and a CNC-supported position detection of a partially prefabricated component. The essential point of the method is the definition of reference surfaces, cut edges, lines or at least points of component components and in particular in the region of their joining zones, this being done by the determination of actual coordinates. Using the actual coordinates, the CAD / CAM setpoint specifications are then revised, on the basis of which at least one, preferably several, machining operations are carried out. The individual possible processing operations are discussed below.

The components to be manufactured here consist of a reinforcing or structural laminate with an inner protective layer. Preferably, the component component in this case consists of a composite with a lining, which consists of a thermoplastic material (liner) or a chemical protection layer (CSS). For processing this component component, these are partly prefabricated, for example, the floors, which are clamped in a winding device, wherein individual cylinder shots assembled according to the size of the component and can be connected to each other. For this purpose, several work to be carried out to ensure that on the one hand the lining material or the

Chemieschutzschicht completely formed on the inside of the component and has a corresponding layer thickness. Likewise, it is important that laminates to be applied on the outside also completely enclose the component and have a corresponding layer thickness.

The method further provides that an exact positioning of the to be joined

Component components or from their CNC - processed joining zones for the joining process on the basis of the revised by means of actual coordinates CAD / CAM setpoint specifications. Decisive for the method is the adaptation of the CAD / CAM setpoint specifications by the determined actual coordinates and the revision of the

CAD / CAM setpoint information, which will eventually be used for further processing.

The component components may in this case be e.g. from a container, in particular storage, process or special containers, from an apparatus, e.g. Column, a centrifuge, an electrostatic precipitator, scrubber, evaporator, filter housing or tubular

Elements, e.g. Gas duct, chimney or liner, pipe manifolds exist. Further, as component components, e.g. Trays, cylinder shots, nozzles, gas inlets and outlets, manholes, possibly with swivel arm for covers, holders for e.g. Swing arms, ladders, lifting eyes, as well as cores of ribs are processed according to this procedure.

All of these component components are exposed to corrosive media, such as e.g. Chemicals or chemicals containing process or flue gases. The

Component components are used, for example, in chemistry, in the microchip industry, in metal extraction and processing, in waste incineration and in power plant technology. For this reason, it is necessary that the lining of thermoplastic materials (liner) or the chemical protection layer (CSS), the inner surface completely covered and in a sufficient thickness. The method according to the invention provides that individual component components are partially prefabricated be clamped on a winding device with or without a core and produced or processed by a winding process using the CAD / CAM setpoint specifications. For this purpose, it is necessary for the component to be detected first after clamping in the form winding device by means of a position detection and determination of a reference surface, -cut edge, -sline or at least -points the actual data and in particular in the region of their joining zones.

The CAD / CAM setpoint specifications revised using actual data can be used in the

Connection, for example, holes, manholes or nozzles, rectangular connections or apparatus flanges are embedded or attached. Likewise, it is necessary that at least partially lifting eyelets or holders for swivel arms, ladders or stages are attached to outer surfaces, including a pretreatment of the outer surfaces is required. The outer surfaces are here by

Leveling and roughening the contact surface between cylinder and overlaminate prepared so that the lifting lugs and ladders can be attached by gluing and / or lamination. However, the leveling and roughening of the contact surfaces is always required if an additional outer layer is to be applied, or if at the joints between floors and cylinders or cylinders and cylinders a firm connection must be created, after joining the lining (thermoplastic Liner or chemical protection layer), or if an additional over-lamination on the outside of a cured prelaminate is to take place, or if reinforcement ribs are to be applied to a cured structural laminate.

As a reference point for processing using the gem. For this purpose, the revised CAD / CAM setpoint specifications are, for example, the inner edge of a bore (inside with respect to the center of the bore and inside with respect to the central axis of the component), or the rear inner edge of the neck (inside with respect to axis and rear as viewed from the flange) , or the joint gap of a connecting seam between the bottom and cylinder or cylinder and cylinder selected. Likewise, as a reference point, the joint gap between liner and bottom and cylinder or between cylinder and cylinder can be selected become. Alternatively, it is possible to select the contour of butt ends or obliquely expiring reinforcing laminates as the reference point in connection laminates. The definition of the reference point takes place before the joining process is to take place. The CNC machining of the joining zones of the joints to be joined

Components are then based on the revised by means of actual coordinates CAD / CAM setpoint specifications immediately before joining or before positioning for

subsequent joining.

Crucial here is that the dimensions of the prepared component can be completely captured using the reference points, and thus, depending on which manufacturing takes place, for example, with liner or CSS chemical protection layer, a

Alignment of the transitions occurs. Furthermore, the required holes, which are to be provided by the CAD / CAM setpoint specifications, can be made CNC controlled from the outside and subsequently the further preparatory work can be performed to the liner or the CSS protective layer and the outer laminate in a later Machining step produce. For this purpose, it is necessary, for example, to prepare the edge region of such a bore or also the neck, which are inserted into the bore, in such a way that a connection takes place between the liner and the CSS chemical protection layer on the inside and the laminate layer on the outside in such a way can ensure that no exposed areas remain and a sufficient layer thickness is present.

Similarly, the joining contours in the area of the bore and the ends of nozzles can be machined CNC-supported, so that they can be joined together and the liner or the CSS protective layer is produced thereafter.

In an embodiment of the method, it is provided that, as far as welding methods are required, these are also CNC-supported or automated, with the reference points for the execution of the work according to the specifications of the CAD / CAM setpoint specifications being of elementary importance. Due to the high precision of the CNC-machined joining zones, liners produce only minimal tolerances as linings, so that welding processes without welding consumables are carried out can be. In this case, kinetic energy is introduced in the smaller joining partners, which is then converted into thermal energy in the joining zone. Welding processes are ultrasonic, vibration or friction welding.

Such machining operations are not possible manually and can only be performed due to the high precision of the present method. In this case, it is furthermore advantageous that automation can be carried out on a robot arm with the aid of a welding head, even in the case of small quantities.

Furthermore, the precision of the CNC machined joining zones on liners enables the automation of quality assurance testing procedures, in particular, test methods for checking the quality of joints of linings. As a test method, for example, the spark test can be done on a weld. Likewise, the thickness of the laminate layer can be determined with the aid of ultrasound and the structure of the wall structure can be checked by means of further test methods.

Insofar as the component components cause larger joining zones due to geometry, a saddle welding method can be used to achieve this

Cover or close the joining zone area.

It is also possible to apply a CNC-supported fixing laminate before the final lamination of the assembled parts of the component takes place.

In a further embodiment of the invention, it is provided that with larger nozzles, manholes and other composite parts, the ends of these parts are measured. Using the revised actual data, the joining zones of the partially manufactured component components are then CNC-machined and then positioned for joining. This ensures that separately manufactured nozzles and

Manholes or other composite components can be fitted precisely to the component body in order to subsequently rejoin the inner lining (liner or the chemical protection layer) and then the

External lamination.

To detect the position of the component in the winding device and the

Actual coordinates of reference surfaces, cutting edges, lines or at least points of component components to be determined exactly, are used for position detection and quality assurance, for example, push-buttons, radio transmission devices, spectroscopy, ultrasound, thermography, scanner or image processing equipment.

On the basis of the aforementioned method, for example, in the free arm winding technique, a CNC-supported position detection can be carried out and the machining can be initiated with the aid of the thus revised CAD / CAM setpoint specifications. As far as connecting pieces are already used, these can also be taken into account with the aid of the CNC-supported position detection. For this purpose, for example, in connection seams of the joint gap between the lining of the bottom and cylinder or between the cylinder and cylinder on the winding shape

measured. This is followed by CNC-assisted trimming followed by a jerk and then CNC-assisted seam preparation and automated welding. For compound laminates, liners or CSS constructions, the contours of butt ends or obliquely running reinforcing laminates are measured afterwards. It then follows a CNC-assisted generation of the required slope or surface activation by roughening the contact surface between the cylinder and overlaminate. If smaller sockets are to be added, it is usually drilled first and then the cutting edge measured. This is followed by the CNC-supported machining of the joining contours in the area of the bore and in the area of the nozzle ends, as well as the CNC-supported roughening of the contact surfaces for the

About laminates. This is followed by CNC-assisted positioning of the CNC machined joint zones of the component parts. Due to the accuracy of machining the joining zones and positioning of the associated joining partners also automated and / or CNC-based methods for joining the

Linings (welding on liners or gluing / laminating with CSS) and possibly also for fixing the laminates, eg by means of resin spatula. An automation regarding overlaminate is the next logical step.

As far as connecting pieces or other components are to be inserted into the soil, these processing steps can be performed in the prefabrication of the soil.

For larger sockets, manholes and other composite parts to be used, the ends of these parts are first measured and then, using the actual data, openings in the partially manufactured component body are CNC-machined and finally the breakthroughs are measured. This is followed by CNC-based machining of the joining contours in the area of the bore and possibly in the area of the end of the nozzle, such as the CNC-supported roughening of the contact surfaces for the

About laminates.

In attachments, such as lifting lugs, holders of swivel arms, ladders and stages, the surface contour in these areas of reinforcement laminates is detected metrologically. This is followed by the CNC-supported leveling of the contact surfaces of semi-finished components and add-on elements as well as a CNC-assisted roughening of the connection surface to the overlaminate. After attaching all nozzles and other components components can again be carried out a measurement of the component, in principle, the structure of the component should already be detected and stored by the work done. Thus, subsequently the CNC-assisted roughening of the partially manufactured body surface or the entire component surface can be further processed, for example by CNC-controlled

Application of the outer layer after the preparatory work is completed.

When the actual data of the component or partially manufactured component is acquired, the edge of the liner or CSS which is in each case inside from the perspective of the component and the part to be inserted is the most important reference variable, since the fluctuation in the thickness of the liner or liner As a rule, CSS is only small and, in the case of reinforcement or structural laminate, it can be assumed that most of the processing steps for maximum masses take place.

In the case of larger parts to be used, the actual data is first recorded; under the condition of a slight fluctuation of liner or CSS, the actual data are to be regarded as the most important data.

The quality assurance can also be carried out with CNC support for all corresponding intermediate steps. For example, the Liner-Stutzenende and the Liner component breakthrough after CNC-supported machining can also be positioned CNC-supported to each other and a CNC-based V-seam pulled from the outside. In addition, the V-seam can be CNC-backed from the outside and a spark test can be carried out. This is usually done using a spark tester from the outside and an arm with grounding, which is inserted into the component.

In a further embodiment of the invention, it is provided that a corresponding designed winding and processing device in the extension of the winding axis or parallel to the process axis of the CNC tools an area can be provided, which not only serves the eventual processing of winding components, but also the CNC supported processing and assembly of externally prefabricated component bodies, for example main pipes of manifolds, droplet separator housings, venturi or three-chamber separators, rectangular tanks, etc. In addition to composite structures, it is also possible to work on pure thermoplastic components.

With the present method, a high quality standard is achieved in the CNC-supported machining of the components. Especially due to position detection and CNC-supported machining with specification of the CAD / CAM setpoint specifications. This leads to an increase in dimensional accuracy, for example, for connections of lines, agitators and stages. The human influences are minimized thereby ensuring a clear quality assurance and increase. By maximizing CNC-based manufacturing processes, such as machining, welding, laminating and Activating and associated quality assurance will largely automate and simplify the process. This reduces the dependence on processing personnel and a safe capacity increase is made possible. The minimization of human presence or the maximization of automation enables, among other things, the integration of radiation-imposing position detection, production and quality assurance procedures without the otherwise necessary production interruption. In addition, the travel times are minimized and the otherwise employed processing personnel is not exposed to damage caused by dust.

Dust which forms can be sucked out immediately, whereby no dust particles are present in the joining area and thus a secure welding is ensured.

The possible work to be carried out automatically and hereby transitions between the individual components of a composite winding component are explained again in the figures.

FIG. 1 shows, in a sectional view, an outer wall of two components 1, 2 which are connected to one another by a joint 3. With the components 1, 2 it can For example, be prepared by two cylinders, which are joined together and connected to each other, in which case the two components 1, 2 consist of a thermoplastic lining layer 4, 5. On the thermoplastic

Lining layer 4, 5, an outer laminate 6 is applied to the component 1 and an outer laminate 7 is applied to the component 2. In the joining region of the two components 1, 2, the outer laminates 6, 7 are beveled, preferably a tilt ratio of 1: 6 is selected. On the tapered areas 8, 9, a further overlaminate 10 is applied, which extends over the region of the joint 3 of the tapered surfaces 8, 9 into the region of the outer laminate 6, 7. Below the overlaminate 10 is a conductive layer 13 for welding control, as far as a thermoplastic material is used. In this case, the joint 3 consists of a weld.

Instead of a thermoplastic lining layer 4, 5, a supporting component body, for example a steel body could be used, which is then provided on the inside with a chemical protective layer. Likewise, the component body may consist of a chemical protection layer, which is connected in the region of the joint 3 and subsequently lamination or lamination takes place. When using a chemical protective layer, the conductive layer 13 is omitted in this case.

FIG. 2 also shows, in a sectional view, the connection of two components 20, 21, which in turn consist of a thermoplastic lining layer 22, 23. The component 20 also has on the outside an outer laminate 24 with a chamfer 25. The second component 21 is retrofitted with a

Outer laminate 26 is provided, which is wound over the joint 27 and the chamfer 25 to the outer laminate 24 of the first member 20. Below the

Overlaminates 26 is a conductive layer 29 for welding control.

Both variants show a way to connect component components, which are cylinders and cylinders and a floor and a Cylinder can act. Also in the solution shown in FIG. 2, instead of the thermoplastic lining layer 22, 23, a supporting construction may be used, which is additionally lined by a chemical protection layer 28. There is also the possibility of a chemical protective layer with an outer laminate for

Reinforcement to use. In this case, the conductive layer 29 is omitted, because instead of welding the chemical protection layer is connected by lamination and requires no further control.

FIG. 3 shows a sectional view of a composite winding component 30 in the lower corner area. The composite winding component 30 consists of a wall 31 and a bottom 32, which are connected to a joint 33. The floor 32 and the wall 31 can be additionally supported by a frame. The wall 31 is made of a thermoplastic material 35, which on the

Outside has a laminate 36. Likewise, the bottom 32 consists of a

thermoplastic material 37 and an outer laminate 38. In the region of the joint 33, the laminates 36, 38 each have a chamfer 39, 40. The joint 33 is further covered by an overlaminate 41, which extends from the laminate of the wall 31 to the laminate 38 of the bottom 32 via the joint 33. As far as a thermoplastic material 35 and 37 is used, a welding takes place, so that the joint 33 consists of a weld. Otherwise, takes place in the region of the joint 33 lamination.

FIG. 4 shows a sectional view of an exemplary embodiment for attaching a nozzle 50 in a tube wall 51. The pipe wall 51 consists of a construction layer 52, such as a thermoplastic material and an outer laminate layer 54. In the pipe wall 51, a bore 55 has been incorporated, in the fitting of the nozzle 50 with its tubular

Wall 57 was used from a thermoplastic material. By means of a weld 58, both parts have been connected to each other, wherein the wall 57 of the nozzle 50 has a lamination 59, which is additionally reinforced by a 60 nierungslamierung 60, wherein the outer lamination 60 along the nozzle 50th extends to the outer lamination 54 of the tubular wall 51. On the

Outside is a conductive layer 53 for weld inspection.

The nozzle itself is equipped with a flange collar 61, so that by means of a coupling ring 62 can be screwed to the other components.

Also in this embodiment, it depends on the extent to which the tubular construction 51 consists, for example, of a thermoplastic layer which requires no further additional chemical protection layer, or of a load-bearing

Metal construction, which must be additionally provided with a chemical protection layer or directly from a chemical protection layer, which is only laminated and no weld is required.
