Abstract
Description
[Technical Field]
[0001] The present invention relates to a device for inserting a pipeline lining into a pipe and for final positioning of the inserted pipeline lining in the pipe, the device comprising a housing, in which a winding device is formed, a mounting element is formed on a first housing opening, and a cover plate or inverter add-on is fastened to at least a second housing opening, as described in claim 1.
[0002] Furthermore, the invention relates to a method for inserting a pipeline lining into a pipe and for the final placement of the inserted pipeline lining in the pipe, in which a device according to the invention is used to carry out this method. [Background technology]
[0003] It is known from the prior art to provide the interior of a pipeline with a pipeline lining, for example a pipeline lining having an outer plastic layer and an inner fiber composite layer, which then has to be inserted into an already laid pipe, for example a pipe laid underground.
[0004] Furthermore, it is often necessary to readjust an already inserted pipe lining with respect to its actual position. Here, for example, it is known to subsequently produce the final or final positioning of the pipe lining by means of a calibration tube. For this purpose, it is necessary to use a device with the help of which the calibration tube can be inserted into the already positioned pipe lining section.
[0005] Therefore, multiple devices are required to insert the pipeline lining into the pipe and then to be able to accurately position the pipeline lining. Summary of the Invention [Problem to be solved by the invention]
[0006] SUMMARY OF THE INVENTION It is therefore an object of the present invention to describe a further developed device in which the above-mentioned drawbacks are overcome.
[0007] It is a further object of the present invention to describe a further developed method for inserting and placing a pipeline lining. [Means for solving the problem]
[0008] According to the invention, the stated object is achieved by the article according to claim 1 in relation to a device for inserting a pipeline lining into a pipe and for the final placement of the inserted pipeline lining in the pipe, and by the method according to claim 6 in relation to a method for inserting a pipeline lining into a pipe and for the final placement of the inserted pipeline lining in the pipe.
[0009] The dependent claims contain at least advantageous embodiments and developments.
[0010] In particular, this object is achieved by an apparatus for inserting a pipeline lining into a pipe and for finally positioning the inserted pipeline lining in the pipe, the apparatus comprising a housing, in particular a drum-shaped housing, in which a winding device is formed and a mounting element, in particular a mounting ring, is formed on a first housing opening, and a cover plate or inverter add-on is fastened to at least the second housing opening, the inverter add-on being fastened to the second housing opening in a first state for inserting the pipeline lining and the cover plate being fastened to the second housing opening in a second state for finally positioning the pipeline lining.
[0011] Thus, according to the invention, a device is provided with the help of which it is possible both to insert a pipeline lining into a pipe and to place an already inserted pipeline lining in its final position.
[0012] The device can therefore exist in at least two states: a first state can be for inserting a pipe lining, in which the inverter add-on is fastened to at least the second housing opening.
[0013] The second state of the device can be a state for final placement of the pipe lining. In this second state, the pipe lining will already be placed or inserted into the pipe. In the second state, a cover plate is fastened to the second housing opening. It is possible for the housing to have additional housing openings. However, at least two openings are formed, with a mounting element formed on the first housing opening and at least a second housing opening closed by an inverter add-on or cover plate.
[0014] The device may also exist in a third state, which may be a maintenance state or a cleaning state, in which the second housing opening may not be open or have additional components fastened or mounted thereon.
[0015] The housing preferably has the shape of a drum, which is particularly visible in a side view of the housing, which shows the axial view of the winding device. Such a drum-shaped design of the housing makes it possible to wind a tube, in particular a calibration tube, onto the winding device as usual with the aid of a coiler.
[0016] An attachment element is formed on the first housing opening. This attachment element can be a part of the housing or a separate component. It is also possible to form the attachment element from both a part of the housing and a separately attached component. Both one end of the pipe lining and one end of the calibration tube are guided through the first housing opening. This depends on the current state of the device or the method step being performed with the device of the present invention. The second housing opening is particularly used to insert the pipe lining into the housing. In other words, the second housing opening is particularly needed in the first state of the device. Closing the second housing opening is particularly needed in the second state of the device of the present invention.
[0017] The drum-shaped housing can have a tubular tapering toward the first housing opening, which may also be referred to as a beak-like housing portion. The beak-like housing portion, in particular, simplifies alignment of the device relative to the pipe into which the pipe lining is to be inserted or in which the pipe lining is to be placed in its final position.
[0018] Additional components can then be fastened to a housing part of this type, for example (additional) mounting elements, in particular (additional) mounting rings.
[0019] Final placement of the pipe lining inserted into the pipe refers to placing the pipe lining in the pipe so that the pipe lining is already in tight contact with the pipe or so that the pipe lining is accurately positioned in the pipe in such a way that additional processing of the pipe lining, such as curing the pipe lining, can be carried out.
[0020] The inverter add-on is a component that can be detachably mounted on the second housing opening. Hereinafter, the inverter add-on will be referred to as a component required during the insertion of the pipeline lining. The inverter add-on can be used to insert the pipeline lining into the housing, and then the pipeline lining can be inserted into the pipe in such a way that the pipeline lining is present inside the pipe in an inverted form compared to its initial state. The initial state of the pipeline lining is understood to mean the state that exists before the pipeline lining is inserted into the device according to the present invention, in particular before the pipeline lining is inserted into the pipe. The inverter add-on can also be referred to as a pipeline lining adapter.
[0021] The inverter add-on can be screwed into the second housing opening. For this purpose, the inverter add-on preferably has a flange-like portion. The flange-like portion preferably has openings through which fastening elements, particularly fastening screws, can be guided. The flange-like portion is preferably formed near the second housing opening of the device so that the flange-like portion of the second housing opening contacts the flange-like portion of the inverter add-on. A detachable connection can then be established by the fastening elements, particularly by a screw or screw-and-nut connection.
[0022] The inverter add-on can have a sealing sleeve and / or a compressed air port. With the aid of the sealing sleeve, it is possible to seal the inverter add-on, and consequently the second housing opening of the device, in such a way that the pressure acting on the pipe lining is not lost with respect to the inserted pipe lining, but instead acts directly on the pipe lining. This simplifies the insertion of the pipe lining into the pipe.
[0023] Furthermore, the inverter add-on can have at least one compressed air port. This compressed air port can be used, in particular, to create a sufficient seal with the aid of a sealing sleeve. For this purpose, the inverter add-on preferably has a flexible chamber portion. This flexible chamber portion is formed, for example, between the sealing sleeve and the inverter housing portion. With the aid of the compressed air port, compressed air can be pumped into this flexible chamber portion in such a way that the sealing sleeve expands and the chamber portion expands. In this form, the sealing sleeve can be pressed against the pipe lining.
[0024] The sealing sleeve is preferably formed from a rubber-like material.
[0025] In a further embodiment of the invention, the housing of the device is provided with a compressed air port, which can be used to apply pressure to the housing itself, for example, in the second state of the device, which can facilitate, for example, the deployment of a calibration tube.
[0026] The inverter add-on may further have a pressure relief opening through which compressed air formed in the inverter add-on can escape.
[0027] The housing may have a compressed air outlet, with the help of which pressure built up in the housing of the device can be released.
[0028] In a preferred embodiment of the present invention, a guide portion for guiding the pipe lining therethrough is formed in the housing of the device, the guide portion starting from the second housing opening and extending to the first housing opening, and the pipe lining is guided from the second housing opening to the first housing opening with the aid of the guide portion.
[0029] At least the first and second housing openings are arranged in the housing in such a way that their opening axes intersect at the center of the housing of the device. The housing center is preferably a portion of the housing corresponding to the longitudinal axis of the winding device. In other words, the opening axis of the first housing opening and the opening axis of the second housing opening intersect near the longitudinal axis of the winding device. The housing opening axes preferably extend at an obtuse angle relative to each other. This means that the pipe lining does not need to bend sharply starting from the second housing opening toward the first housing opening. Instead, the pipe lining can extend linearly in at least some portions while being guided within the device.
[0030] This obtuse angle of the housing opening axis is preferably between 110° and 150°, particularly preferably between 140° and 145°, and especially preferably between 130° and 140°.
[0031] In the first state, the winding device preferably has the calibration tube wound on it. The winding device may, for example, be an electrically operable winding device. Furthermore, the winding device preferably has a locking means for securing the winding device against undesired unwinding and winding. Therefore, in the first state of the device, the locking means is preferably engaged.
[0032] The housing of the device is preferably fastened to a transport device, which may be a wheelbarrow-like device, which preferably has at least two wheels or rollers and at least one gripping unit, so that the device according to the invention can be easily transported.
[0033] An additional aspect of the present invention relates to a method for inserting a pipeline lining into a pipe and for final placement of the inserted pipeline lining in the pipe.
[0034] This method according to the invention provides the use of a device according to the invention. a) providing a device according to the present invention, the device having a calibration tube wound on it; b) fastening an inverter add-on to the second housing opening; c) guiding a first end of the pipeline lining from the second housing opening to the first housing opening and fastening the first end of the pipeline lining to the mounting element; d) increasing the pressure at the inverter add-on and / or in the housing, in particular by compressed air; e) inserting a pipeline lining into the pipe; Includes:
[0035] Steps a) to e) according to the invention are preferably carried out in the order described. Steps a) and b) can be carried out, for example, simultaneously or in reverse order. When carrying out the described steps, it is important to first create a first state of the device for inserting a pipeline lining into a pipe.
[0036] Between steps c) and e), it is possible to extend a support tube in a plurality of sections in the direction of the pipe and fasten the support tube extended over the first end of the pipe lining to the attachment element.
[0037] The pipe lining can be easily inserted into the pipe with the aid of a support tube that spans the empty space between the first opening of the device and the beginning of the pipe to be treated or repaired, in which case the support tube acts as a kind of guide that allows the pipe lining to be inserted into the pipe in a targeted manner.
[0038] The support tube can be inserted, for example, until it enters the pipe to be repaired or treated. For example, the support tube can extend approximately 10 cm into the pipe to be treated. The support tube is preferably guided over the first end of the pipe lining and fastened to a mounting element, particularly a mounting ring, while attached to the first end of the pipe lining. This fastening can be achieved, for example, by a tension strap and / or a tension ring.
[0039] The support tube is inserted between steps c) and e), which is preferably performed between steps c) and d).
[0040] In step c), a first end of the pipe lining is fastened to the mounting element. For this purpose, the tubular pipe lining is first guided through the housing and folded back at the first end. Thus, at the first end of the pipe lining, the inner surface of the pipe lining is turned outward, so that what was originally the inner surface of the pipe lining then forms the outer surface when fastened to the mounting element.
[0041] The first pipe lining is fastened to the mounting element in an outward-facing configuration, so that when the pipe lining is inserted into the pipe, it can be turned over and completely inserted into the pipe. Because the pipe lining is oriented outward, it can be impregnated with the resin mixture in a particularly favorable manner. The resin is preferably applied to the inner surface of the pipe lining, and because it is oriented outward, the resin simply moves outward, which allows for particularly simple handling of the pipe lining that has already been impregnated with the resin.
[0042] Step a) can furthermore comprise, when providing the device according to the invention, connecting a retaining cord to the device and winding the retaining cord together with, for example, the circulation tube and the condensate discharge tube within the device.
[0043] The calibration tube is preferably wound onto the winding device in such a way that the second end of the calibration tube is wound onto the winding device first, where the second end of the calibration is understood to be the end of the calibration tube that is unwound last or that represents the last unwound portion of the calibration tube during the process of unwinding the calibration tube.
[0044] In step c), the first end of the pipeline lining may be fastened to the attachment element, for example by means of a tension strap and / or a tension ring.
[0045] In a further embodiment of the present invention, the method includes step f), in which pressure is released from the inverter add-on and / or housing after step e) is completed. In other words, after the pipe lining is fully inserted into the pipe, the previously applied pressure is first released from the inverter add-on and / or housing.
[0046] Only after the pressure is released can the inverter add-on be removed from the housing in step g) and then a cover plate can be fastened to the second housing opening in such a manner that the second housing opening is closed.
[0047] In the first state of the device, the second housing opening is not completely closed, but rather the inverter add-on provides a type of access to the housing so that a conduit line can be inserted into the device from the outside.
[0048] Furthermore, in step h), the first end of the pipeline lining and the optionally fastened support tube are removed from the mounting element. Step h) is preferably performed after step f). Step h) can be performed after step g). Furthermore, step h) can be performed between steps f) and g).
[0049] When step h) is performed, the component and / or tube portion that was originally in contact with the attachment element is no longer present.
[0050] In step i), the first end of the calibration tube can be unwound from the winding device and fastened to the mounting element. The first end of the calibration tube is preferably fastened to the mounting element in such a way that the calibration tube is also oriented outward and is fastened to the mounting element in this outwardly oriented configuration. This fastening to the mounting element can be achieved by a tension strap and / or a tension ring.
[0051] According to step j), the first end of the pipeline lining and optionally the support tube can be stretched over the first end of the calibration tube and fastened to the mounting element. First, the first end of the pipeline lining and then the support tube can be guided over the calibration tube mounted on the mounting element so that, from the inside to the outside, the first end of the calibration tube, the first end of the pipeline lining and optionally the support tube can be mounted on the mounting element and fastened to the mounting element.
[0052] This fastening of the pipe lining and the support tube makes the calibration tube particularly convenient, since neither the pipe lining nor the optional support tube undergoes undesired displacement during the calibration process. By attaching the support tube, the calibration tube is guided smoothly from the first housing opening to the beginning of the pipe. Again, the support tube can extend approximately 10 cm into the pipe.
[0053] In step k), the pressure in the housing is increased, and due to this pressure increase, the calibration tube is placed in the pipe lining and expands, so that the pipe lining is placed in its final position. Due to this pressure increase, the calibration tube is unwound from the winding device and is increasingly pressed into the pipe, in particular the pipe lining.
[0054] The calibration tube is turned upside down and passes from the device into the pipe lining. Step k) is preferably continued until the calibration tube is fully installed. If the device has a retaining cord, a length marker on the retaining cord can provide information about the position of the calibration tube. With the help of this retaining cord, the position of the second end of the calibration tube can be known at any time.
[0055] The execution speed of step k) can be controlled with the aid of the pressure buildup in the housing and can be monitored with the aid of the holding cord.
[0056] Pipe linings can be constructed from resin-coated nonwoven fabric tubes. These are also known as tube liners. When the pipe lining is inserted into the pipe, the inner surface of the pipe lining faces outward. Inserting the pipe lining in this manner is also called inversion.
[0057] In step e), the pipe lining is completely ejected with the aid of a compressed air supply and is then inverted. After the perfectly correct or final positioning, the pipe lining is in a form that allows the resin of the pipe lining to harden. This type of hardening process can be carried out, for example, by steam and / or infrared radiation. Since the pipe lining is already in the correct position, no additional positioning steps need to be carried out during this hardening process.
[0058] The method according to the invention is based on the use of the device according to the invention, which for the first time makes it possible to carry out both the introduction or insertion of the pipeline lining and the final placement of the pipeline lining with a single device, which is associated with a significant saving in the amount of equipment that needs to be kept in working order.
[0059] The invention will now be explained in more detail on the basis of exemplary embodiments with reference to the accompanying schematic drawings. [Brief explanation of the drawings]
[0060] [Figures 1a-1c] 1A-1D show a device according to the invention in different states; [Figure 2a-2b] 10A and 10B are cross-sectional views of an inverter add-on without a pipe lining inserted therein and an inverter add-on with a pipe lining inserted therein; [Figure 3a-3c] 1 shows the different stages of the method according to the invention; DETAILED DESCRIPTION OF THE INVENTION
[0061] In the following, the same reference numerals are used for the same and functionally identical components.
[0062] 1a shows the main structure of the device 10 according to the invention. The device 10 has a drum-shaped housing 20 in which a winding device 25 is formed. In the simplest case, the winding device 25 can be formed as a kind of spindle, onto which a tube, in particular a calibration tube 70, can be wound.
[0063] The calibration tube 70 has a first end 71 and a second end 72. In this case, the second end 72 is wound or wrapped first, so that the first end 71 is the last wound or wrapped end of the calibration tube 70. The housing 20 is fixed on a carrier 90. The carrier 90 essentially has two rollers 91, a grip portion 92, and a frame 93. The frame 93, among other things, prevents the carrier from being able to tilt when the carrier is stationary. The frame 93 therefore allows the device 10 to be stably positioned while the method according to the invention is being performed.
[0064] The housing 20 has a substantial drum shape. The housing 20 further has a first housing opening 21 and a second housing opening 22. The housing 20 has a housing portion 23 facing the first housing opening 21. This housing portion 23 extends in the direction of the first housing opening 21 so as to taper. With the help of this type of housing portion 23, a kind of guide can be ensured within the housing 20.
[0065] Additionally, the housing 20 has at least one compressed air port 26 and one compressed air indicator or pressure gauge 27 .
[0066] A housing opening 30 is formed near the second housing opening 22. This housing opening 30 is used in particular for fastening different components. For this purpose, the housing opening 30 has a flange element 31.
[0067] The housing opening 21 has a first housing opening axis A1, and the housing opening 22 has a second housing opening axis A2. It can be seen that the two housing opening axes A1 and A2 intersect near the winding device 25, i.e., near the longitudinal axis of the winding device 25. The housing opening axes A1 and A2 are disposed at an angle α to each other. The angle α is preferably an obtuse angle, and is preferably 135°.
[0068] Such an angle allows the pipe lining to be guided at a relatively free angle within the housing 20 (see FIG. 1b). In FIG. 1a, an inverter add-on 40 is fastened to the housing opening 22. A more precise view of the inverter add-on 40 is shown in FIG. 2.
[0069] A guide portion 33 is further formed in the housing 20. With the help of the guide portion 33, the tube, in particular the pipe lining 80, can be guided from the second housing opening 22 in the direction of the first housing opening 21.
[0070] In Figure 1b, the device 10 is shown according to a first state for inserting a pipeline lining 80 into a pipe. It can be seen that the pipeline lining 80 is guided from the second housing opening 22 to the first housing opening 21. At a first end 81 of the pipeline lining 80, the pipeline lining 80 is fastened to a mounting element 35. The mounting element 35 is a mounting ring.
[0071] In the illustrated example, the mounting element 35 is fastened to the housing portion 23. It is also possible for the mounting element 35 to be formed as an integral component of the housing 20. The pipe lining 80 is placed on or fastened to the mounting element 35 with its first end 81 in such a way that the inner surface 82 faces outward and forms the outer surface of the pipe lining 80 in the fastened state. In contrast, the outer surface 83 is visible when placed within the device 10.
[0072] The first end 81 of the pipe lining 80 is preferably fitted onto the mounting element 35 by a tension strap 88 .
[0073] In the first state of the apparatus 10, the wrapping device 25 is secured in such a way that the calibration tube 70 does not unravel from the wrapping device 25 during insertion of the pipeline lining 80.
[0074] 1c further shows that a support tube 75 can be fastened to the mounting element 35. The support tube is pushed over the folded first end 81 of the pipe lining 80 and, in this case, is also fastened to the mounting element 35 by a tension strap 88. The support tube 75 is used to insert the pipe lining into the pipe in a guided manner. The support tube 75 preferably reaches the pipe. For example, the support tube 75 can extend up to 10 cm into the pipe during the insertion process, so that the pipe lining 80 can be particularly easily introduced into the pipe without the pipe lining 80 being able to move uncontrollably in the space between the pipe and the first housing opening 21, which would otherwise be empty.
[0075] 2a shows the inverter add-on 40 in more detail. It is understood that the inverter add-on is the component necessary to insert the pipeline lining 80 into the pipe, and the pipeline lining 80 is inserted in such a way that the sides of the pipeline lining are folded back such that the previously formed inner surface of the pipeline lining is turned outward or inside out by compressed air during insertion of the pipeline lining 80 into the pipe. The inverter add-on 40 can also be referred to as a pipeline lining adapter.
[0076] In Figure 2a the inverter add-on 40 is shown without the inserted pipe lining 80. In Figure 2b the function of the inverter add-on 40 is shown with the inserted pipe lining 80.
[0077] First, the inverter add-on 40 has a flange element 41. With the help of the flange element 41 of the inverter add-on 40, it is possible to fasten the inverter add-on 40 to the flange element 31 of the housing 20. A ring seal 42 is provided to achieve a sealing function.
[0078] The inverter add-on 40 basically comprises a sealing sleeve 43 and a first fastening attachment 44. One end of the sealing sleeve 43 can be fastened to the first fastening attachment 44 by, for example, a pipe clamp 46.
[0079] The second end of the sealing sleeve 43 is fastened to a second fastening attachment 47. This fastening to the fastening attachment 47 may also be achieved by a tubing clamp 46. The sealing sleeve is preferably made of plastic.
[0080] The sealing sleeve has a length that allows it to expand toward the center 48 of the inverter add-on 40. The sealing sleeve forms a flexible chamber portion 50 between the sealing sleeve 43 and the inverter housing portion 49.
[0081] The volume of the flexible chamber portion 50 can be increased or decreased. For this purpose, the inverter add-on 40 has a compressed air inlet 51 and a compressed air outlet 52. In the illustrated example, the compressed air inlet 51 and also the compressed air outlet 52 can be understood to be part of a three-way valve 53. In the illustrated example, this valve is specifically a three-way threaded ball valve. Compressed air can be supplied or discharged by operating a knob 54. By increasing the injection of compressed air into the flexible chamber portion 50, the sealing sleeve 43 expands in the direction of the center 48 of the inverter add-on 40.
[0082] 2b shows the expanded state of the sealing sleeve 43 and therefore the large volume for the flexible chamber portion 50. Furthermore, fastening means 55 are shown, with the help of which the inverter add-on 40 can be fastened to the housing 20 or to the housing opening portion 30. In this case, the fastening means 55 is formed as a screw connection.
[0083] In the configuration shown in Fig. 2b, on the one hand, the inserted pipe lining 80 can be moved in the direction of the first housing opening 51, and on the other hand, thanks to the presence of the sealing sleeve, the second housing opening 22 is sealed against the introduced pipe lining. The pressure acting on the pipe lining 80 is not lost, but acts directly on the pipe lining 80. This simplifies the introduction of the pipe lining 80 into the pipe.
[0084] When the conduit lining 80 is fully inserted into the pipe, the compressed air located in the flexible chamber portion 50 can be discharged through the outlet 52. The sealing sleeve 43 is moved back towards the lateral inverter housing portion 49, so that the volume of the flexible chamber portion 50 is reduced again. In this case, the pressure acting on the conduit lining 80 decreases, so that the end of the conduit lining 80 can be easily handled again, and at the same time the inverter add-on 40 can be removed from the housing 20.
[0085] 3a to 3c show the various method steps relating to the insertion of the pipeline lining 80 and its final placement by the insertion of the calibration tube 70. FIG.
[0086] 3a shows, on the one hand, that the first end 81 of the pipe lining 80 has already been fastened to the mounting element 35. Furthermore, the path of the support tube 75 is also shown. The support tube 75 is stretched over the first end 81 of the pipe lining 80 and fastened to the mounting element 35. The support tube 75 is placed through the manhole 99 toward the pipe 100. With the help of the support tube 75, the pipe lining 80 can consequently be intentionally stretched toward the pipe 100. According to the first state of the device 10, the inverter add-on 40 is fastened to the second housing opening 22. While the pipe lining 80 is being inserted into the pipe 100, the calibration tube 70 remains on the winding device 25.
[0087] The pipe lining 80 is inserted into the pipe 100 to the desired length using compressed air, as shown in Figure 3b.
[0088] After the pipe lining 80 has been completely introduced into the pipe 100, the pipe lining 80 is placed in its final position in the second state of the device 10. For this purpose, the inverter add-on 40 is removed from the second housing opening 22. A cover plate 25 is fitted into the second housing opening 22 in place of the inverter add-on 40. Before removing the inverter add-on 40, pressure must be relieved or compressed air must be evacuated from the inverter add-on 40 and / or the housing 20.
[0089] The cover plate 45 is fitted into the second housing opening 22 in such a way that the second housing opening 22 is completely closed. In this second state, first the first end 81 of the pipe lining 80 and optionally the fastened support tube 75 are removed from the mounting element 35. The calibration tube 70 is pulled in the direction of the first housing opening 21 by grasping the first end 71 and is likewise fastened to the mounting element 35 in an inverted state.
[0090] The first end 81 of the pipe lining 80 is then pushed over the first end 71 of the calibration tube 70. The support tube 75 can then be pushed or stretched over the first end 81 of the pipe lining 80. In this arrangement, the calibration tube, pipe lining and support tube are fastened to the mounting element 35.
[0091] 3c, by supplying compressed air to the calibration tube 70 in this fastened configuration, the calibration tube can be pushed into the pipe lining 80. By supplying compressed air to the calibration tube 70, the pipe lining 80 can be pushed outward, so that the pipe lining 80, for example, a pipe lining 80 with resin impregnated on the sides, can be pushed outward, i.e., toward the pipe 100.
[0092] When the calibration tube 70 is fully seated within the pipeline lining 80, the pipeline lining 80 can be fully seated. The calibration tube 70 can then be removed.
