Description

管構件的探傷檢查方法及管構件的探傷檢查系統Pipe component flaw detection and inspection method and pipe component flaw detection and inspection system

本發明係關於一種使用了被***於管構件之內部的探傷感測器之管構件的探傷檢查方法及管構件的探傷檢查系統。The present invention relates to a flaw detection and inspection method for a pipe member using a flaw detection sensor inserted into the inside of the pipe member and a flaw detection and inspection system for the pipe member.

在如常規鍋爐(conventional boiler)或廢熱回收鍋爐(HRSG：Heat Recovery Steam Generator；熱回收蒸汽產生器)的鍋爐設備中所使用之傳熱管等的管構件上，有時會發生藉由腐蝕所致之減薄等的異常。因當如此的異常發展至損傷時，就有為了對策及恢復原狀而需要許多的時間與成本，故而被要求藉由檢查來早期地掌握此等的異常。On pipe components such as heat transfer tubes used in boiler equipment such as conventional boilers or waste heat recovery boilers (HRSG: Heat Recovery Steam Generator), corrosion caused by corrosion may sometimes occur. Causes abnormalities such as thinning. When such an abnormality progresses to damage, it takes a lot of time and cost for countermeasures and restoring to the original state. Therefore, it is required to early grasp the abnormality through inspection.

在例如專利文獻1，係已揭示一種檢查手法，其是將包含渦流探傷感測器的探傷檢查裝置***於管構件之內部，且基於所取得的李沙育波形(Lissajous waveform)，來判定管構件中的異常。然而，在專利文獻1之手法中，因有必要藉由作業員進行已***於管構件的探傷檢查裝置之移動，故而為了遍及於管構件之較寬的範圍地進行檢查，而花了許多的時間。For example, Patent Document 1 discloses an inspection method, which is to insert a flaw detection inspection device including an eddy current flaw detection sensor into a pipe member, and determine whether the pipe member is in the pipe member based on the obtained Lissajous waveform. The exception. However, in the method of Patent Document 1, since it is necessary for the operator to move the inspection device inserted into the pipe member, it takes a lot of effort to inspect a wider area of the pipe member. time.

作為對如此的專利文獻1中之課題的解決方案之一，在例如專利文獻2中，係有提出以下的內容：在探傷檢查裝置已***於管構件的狀態下，將水流供應至管構件，藉此探傷檢查裝置就會利用從水流所接受的水壓在管構件之內部移動。 [先前技術文獻] [專利文獻]As one of the solutions to the problem in Patent Document 1, for example, Patent Document 2 proposes the following: in a state where a flaw detection and inspection device has been inserted into a pipe member, a water flow is supplied to the pipe member, In this way, the flaw detection and inspection device will use the water pressure received from the water flow to move inside the pipe member. [Prior Technical Literature] [Patent Literature]

專利文獻1：日本特開平5-312787號公報 專利文獻2：日本特開2011-75384號公報Patent Document 1: Japanese Patent Laid-Open No. 5-312787 Patent Document 2: Japanese Patent Application Publication No. 2011-75384

在利用如上述專利文獻2的水壓進行探傷檢查裝置之移動的檢查手法中，係需要用以對管構件供應水流的液壓泵(hydraulic pump)。因在鍋爐設備中所使用的管構件，一般是包含有屈曲部，故而為了要一邊對屈曲部使探傷檢查裝置準確地通過，且一邊遍及於寬範圍地進行檢查，被要求某程度強的水壓。為此，需要比較大型的液壓泵。又，雖然從液壓泵所供應的水流，例如是透過軟管(hose)供應至管構件，但是為了防止軟管與管構件之連結部中的水流之洩漏，也有必要在該連結部中使用厚重的聯結器(coupler)。如此，在利用水壓的檢查手法中，用以實施該手法的附帶設備(液壓泵或聯結器等)容易大型化方面將成為課題。In the inspection method for moving the flaw detection inspection device using the water pressure as described in Patent Document 2, a hydraulic pump for supplying water flow to the pipe member is required. Because the pipe members used in boiler equipment generally include flexures, in order to accurately pass the flaw detection device through the flexures, and to perform inspections over a wide area, a certain degree of strong water is required. Pressure. For this reason, a relatively large hydraulic pump is required. In addition, although the water flow supplied from the hydraulic pump is supplied to the pipe member through a hose, for example, in order to prevent the leakage of the water flow in the connecting portion of the hose and the pipe member, it is necessary to use a thick weight in the connecting portion. The coupler (coupler). In this way, in the inspection method using water pressure, the auxiliary equipment (hydraulic pump, coupler, etc.) for implementing the method is likely to be increased in size.

又，成為檢查對象的管構件，係配置於鍋爐設備的燃燒爐之內部。雖然在燃燒爐之內部，係能夠透過例如人孔(manhole)的開口部來進出(access)，但是為了確保燃燒爐之效率一般是比較窄的開口部。為此，因上述的液壓泵等之大型的附帶設備係無法通過開口部，故而會被配置於燃燒爐之外部。如此，在液壓式的檢查系統中，因從成為檢查對象的管構件至附帶設備為止的距離會變遠，故而系統也容易變成大規模，且處理不容易。In addition, the pipe member to be inspected is arranged inside the combustion furnace of the boiler facility. Although the inside of the combustion furnace can be accessed through an opening such as a manhole, in order to ensure the efficiency of the combustion furnace, a relatively narrow opening is generally used. For this reason, since the above-mentioned large auxiliary equipment such as the hydraulic pump cannot pass through the opening, it is arranged outside the combustion furnace. In this way, in a hydraulic inspection system, the distance from the pipe member to be inspected to the auxiliary equipment becomes longer, so the system is likely to become large-scale, and handling is not easy.

本發明之至少一實施形態係有鑑於上述之情形而開發完成，其目的在於提供一種構成簡單且能夠一邊使管構件之內部的探傷感測器移動，且一邊檢查管構件之管構件的探傷檢查方法及管構件的探傷檢查系統。At least one embodiment of the present invention was developed in view of the above-mentioned situation, and its purpose is to provide a simple structure that can move the flaw detection sensor inside the pipe member while inspecting the pipe member.

The obtained inspection signal is used to inspect the aforementioned pipe member.

依據上述(3)的構成，藉由對***有探傷檢查裝置的管構件供應氣體，就可以藉由在管構件之內部所產生的氣流一邊使探傷檢查裝置移動且一邊實施檢查。使用了如此之氣流的探傷檢查裝置之移動，因附帶設備比利用液壓的情況還可簡單完成，故而處理也容易。 According to the configuration of (3) above, by supplying gas to the pipe member into which the flaw detection and inspection device is inserted, it is possible to perform inspection while moving the flaw detection and inspection device by the air flow generated inside the pipe member. The movement of the flaw detection and inspection device using such airflow can be completed more easily than the case of using hydraulic pressure, so it is easy to handle.

(4)在幾個實施形態中係如上述(3)的構成，其中，前述管構件，係配置於具有為了與外部之進出而設置之開口部的燃燒爐之內部；前述分析裝置，係配置於前述燃燒爐之內部。 (4) In some embodiments, it is the configuration as in (3) above, wherein the pipe member is arranged inside a combustion furnace having an opening provided for access to the outside; the analysis device is arranged In the interior of the aforementioned combustion furnace.

如上面所述，藉由氣流來實現管構件之內部的探傷檢查裝置之移動，藉此就可以簡化包含分析裝置的附帶設備。藉此，在上述(4)的構成中，係可以將進行檢查訊號之分析的分析裝置配置於燃燒爐之內部。 As described above, the movement of the flaw detection and inspection device inside the pipe member is realized by the airflow, thereby simplifying the accessory equipment including the analysis device. Therefore, in the above-mentioned configuration (4), the analysis device for analyzing the inspection signal can be arranged inside the combustion furnace.

(5)在幾個實施形態中係如上述(3)或(4)的構成，其中，前述探傷檢查裝置，係具備：探傷感測器；以及連接於前述探傷感測器的至少一個可撓性(flexible)結構體；前述至少一個可撓性結構體，係在沿著長度方向的既定間隔之位置，具有朝向徑向突出的至少一個突出部。 (5) In some embodiments, the configuration is as described in (3) or (4) above, wherein the aforementioned flaw detection inspection device is provided with: a flaw detection sensor; and at least one flexible sensor connected to the aforementioned flaw detection sensor (Flexible) structure; the aforementioned at least one flexible structure is located at a predetermined interval along the length direction, and has at least one protrusion protruding toward the radial direction.

依據上述(5)的構成，構成探傷檢查裝置的可撓性結構體，係設置有突出部，藉此可以在探傷檢查裝置已***於管構件時，減低與管構件之內壁的接觸面積。 結果，探傷檢查裝置可以以較少的阻力在管構件之內部移動。藉此，例如，即便是在管構件具有屈曲部的情況下，可撓性結構體仍不會在屈曲部壓曲(不會發生堵塞)，而能夠進行平滑(smooth)的移動。 According to the configuration of (5) above, the flexible structure constituting the flaw detection and inspection device is provided with a protrusion, whereby the contact area with the inner wall of the pipe member can be reduced when the flaw detection and inspection device is inserted into the pipe member.

以下，參照附圖來加以說明本發明之幾個實施形態。但是，被記載作為實施形態或圖式所示的構成零件之尺寸、材質、形狀、其相對配置等，趣旨不在於將本發明之範圍限定於此，而只不過是單純的說明例而已。Hereinafter, several embodiments of the present invention will be described with reference to the drawings. However, the dimensions, materials, shapes, and relative arrangements of the components described as embodiments or drawings are not intended to limit the scope of the present invention to these, but are merely illustrative examples.

圖1係顯示本發明之至少一實施形態的探傷檢查系統100之整體構成的示意圖。探傷檢查系統100，例如是將如常規鍋爐或廢熱回收鍋爐(HRSG: Heat Recovery Steam Generator)的鍋爐設備中所使用之傳熱管等的管構件10作為檢查對象。管構件10，係具有包含直管部10a及彎曲部10b的任意形狀，該直管部10a係具有直管(straight)形狀，該彎曲部10b係具有彎曲形狀。FIG. 1 is a schematic diagram showing the overall structure of a flaw detection inspection system 100 according to at least one embodiment of the present invention. The flaw detection inspection system 100 uses, for example, a tube member 10 such as a heat transfer tube used in a boiler facility such as a conventional boiler or a heat recovery steam generator (HRSG: Heat Recovery Steam Generator) as an inspection object. The pipe member 10 has an arbitrary shape including a straight pipe portion 10a and a curved portion 10b, the straight pipe portion 10a has a straight pipe (straight) shape, and the curved portion 10b has a curved shape.

管構件10，係配置於鍋爐設備的燃燒爐12之內部空間。燃燒爐12之內部空間，係由包含絕熱材料或傳熱管等的壁面14所包圍而界定。在圖1中，僅簡略地顯示構成燃燒爐12的壁面14之一部分。The pipe member 10 is arranged in the internal space of the combustion furnace 12 of the boiler facility. The internal space of the combustion furnace 12 is bounded by a wall 14 containing heat insulating materials or heat transfer tubes. In FIG. 1, only a part of the wall surface 14 constituting the combustion furnace 12 is schematically shown.

又，在壁面14，係設置有：在作業員進出於內部空間或對內部空間導入或排出各種器材時被使用作為通路的開口部16。開口部16，係具有能夠開閉的蓋構件(未圖示，所謂的人孔)，且依需要用蓋構件來閉塞開口部16，藉此構成能夠從外部隔離燃燒爐12之內部空間。In addition, the wall surface 14 is provided with an opening 16 which is used as a passage when an operator enters and exits the internal space, or introduces or discharges various equipment into the internal space. The opening 16 has a cover member (not shown, a so-called manhole) that can be opened and closed, and the opening 16 is closed by the cover member as needed, thereby constituting an internal space capable of isolating the combustion furnace 12 from the outside.

在燃燒爐12，係為了確保良好的燃燒效率，開口部16之大小被限制於必要最低限度的大小。此是因當開口部16佔燃燒爐12之壁面14的比例變大時，從燃燒爐12所失掉的熱能量就會增加，藉此會使效率降低所致。為此，使通過開口部16的器材，就要被限制於比開口部16之大小還小的器材。In the combustion furnace 12, in order to ensure good combustion efficiency, the size of the opening 16 is limited to the minimum necessary size. This is because when the ratio of the opening 16 to the wall surface 14 of the combustion furnace 12 increases, the heat energy lost from the combustion furnace 12 increases, thereby reducing the efficiency. For this reason, the equipment passing through the opening 16 must be restricted to equipment smaller than the size of the opening 16.

探傷檢查系統100，係具備能夠從管構件10之端部***於內部的探傷檢查裝置110。在此，圖2係從側方穿透性地顯示已***於管構件10的探傷檢查裝置110之示意圖。The flaw detection and inspection system 100 is provided with a flaw detection and inspection device 110 that can be inserted into the inside from the end of the pipe member 10. Here, FIG. 2 is a schematic diagram showing the flaw detection inspection device 110 inserted into the pipe member 10 penetratively from the side.

探傷檢查裝置110，係設置有用以進行使用了超音波之探傷測定的探傷感測器112，該探傷感測器112係連接於電纜(cable)狀之可撓性結構體114所構成。探傷感測器112為超音波感測器，其是在探傷檢查裝置110已***於管構件10之內部時，朝向管構件10之管壁振盪超音波，並且接收在管壁反射後的接收回波訊號(echo signal)，且相應於該超音波之強度而輸出接收回波訊號。The flaw detection inspection device 110 is provided with a flaw detection sensor 112 for performing flaw detection measurement using ultrasonic waves, and the flaw detection sensor 112 is connected to a cable-shaped flexible structure 114. The flaw detection sensor 112 is an ultrasonic wave sensor, which oscillates the ultrasonic wave toward the pipe wall of the pipe member 10 when the flaw detection inspection device 110 has been inserted into the pipe member 10, and receives the received return after reflection on the pipe wall Echo signal, and output the received echo signal corresponding to the intensity of the ultrasonic wave.

可撓性結構體114，係指沿著管構件10之長度方向而延伸的電纜狀構件，且具有比探傷感測器112還十分大的長度。又，可撓性結構體114，係包含柔軟性優異的材料所形成，且在探傷檢查裝置110已***於管構件10時，能夠相應於管構件10之形狀而柔軟地變形。The flexible structure 114 refers to a cable-shaped member extending along the length direction of the pipe member 10 and has a length that is considerably longer than that of the flaw detection sensor 112. In addition, the flexible structure 114 is formed of a material with excellent flexibility, and when the flaw detection inspection device 110 is inserted into the pipe member 10, it can be flexibly deformed according to the shape of the pipe member 10.

The flexible structure 114 is provided with: a tension member 116, which is disposed at the center; and at least one signal cable 118, which is disposed on the radially outer side of the tension member 116; and a protective layer 120, which It is arranged on the radially outer side of at least one signal cable 118. The tension member 116 includes a wire 116a made of a metal material such as stainless steel, and its surface is covered with a film 116b such as polyurethane. The signal cable 118 includes a signal cable (such as a coaxial cable) for transmitting various signals between the flaw detection sensor 112 and the analysis device 200 (refer to FIG. 1 ), and is arranged to surround the tension member 116. The protective layer 120 is formed of an insulating material such as PVC to protect the tension member 116 and the signal cable 118 that have been arranged inside.

如圖2所示，在如此的可撓性結構體114，係設置有至少一個突出部122。突出部122，係以局部性地朝向徑向外側突出的方式設置於電纜狀之可撓性結構體114。為此，當探傷檢查裝置110***於管構件10時，突出部122就會優先地接觸於管構件10之內壁。結果，可減少探傷檢查裝置110對管構件10之內壁的接觸面積。藉此，在探傷檢查裝置110移動於管構件10之內部時，可以減低在與管構件10之內壁之間所產生的摩擦力，且探傷檢查裝置110能夠在管構件10之內部進行平滑的移動。 As shown in FIG. 2, such a flexible structure 114 is provided with at least one protrusion 122. The protruding portion 122 is provided on the cable-shaped flexible structure 114 so as to locally protrude toward the radially outer side. For this reason, when the flaw detection and inspection device 110 is inserted into the pipe member 10, the protrusion 122 will preferentially contact the inner wall of the pipe member 10. As a result, the contact area of the flaw detection and inspection device 110 to the inner wall of the pipe member 10 can be reduced. Thereby, when the flaw detection and inspection device 110 moves inside the pipe member 10, the frictional force generated between it and the inner wall of the pipe member 10 can be reduced, and the flaw detection and inspection device 110 can perform smoothing inside the pipe member 10. mobile.

在圖2中特別的是，複數個突出部122，係以既定間隔設置於沿著管構件10延伸的可撓性結構體114。為此，即便是在管構件10及於長距離的情況下，仍能夠在管構件10之內部遍及於寬範圍地進行平滑的移動。 In particular, in FIG. 2, a plurality of protrusions 122 are provided at a predetermined interval on the flexible structure 114 extending along the pipe member 10. For this reason, even in the case of the pipe member 10 and a long distance, the pipe member 10 can still move smoothly over a wide range.

如後面所述，在探傷檢查裝置110已***於管構件10的狀態下，對管構件10之內部供應有氣體，藉此就會從管構件10之端部朝向裡側形成有氣流F。因上述的突出部122，係比可撓性結構體114之外表面更朝向徑向外側突出，故而可藉由接受氣流F，來對探傷檢查裝置110賦予沿著該氣流F的推進力。藉此，即便是在可撓性結構體114是包含柔軟性優異的材料所構成的情況下，仍可以藉由基於氣流F的推進力，不在管構件10之內部因壓曲等而 發生堵塞地平滑移動。 As described later, in a state where the flaw detection and inspection device 110 has been inserted into the pipe member 10, gas is supplied to the inside of the pipe member 10, whereby the air flow F is formed from the end of the pipe member 10 toward the inner side. Since the above-mentioned protruding portion 122 protrudes radially outward than the outer surface of the flexible structure 114, it can receive the air flow F to impart a propelling force along the air flow F to the flaw detection inspection device 110. Thereby, even in the case where the flexible structure 114 is composed of a material with excellent flexibility, the propelling force based on the air flow F can prevent the inside of the pipe member 10 from being buckled and the like. It moves smoothly with clogging.

在本實施形態中，如上面所述，由於複數個突出部122是以既定間隔設置於可撓性結構體114，所以已***於管構件10的探傷檢查裝置110，係可以遍及於較寬的範圍地從氣流F接受推進力。 In this embodiment, as described above, since the plurality of protrusions 122 are provided on the flexible structure 114 at predetermined intervals, the flaw detection and inspection device 110 inserted into the pipe member 10 can be spread over a wide area. Receive the propulsion force from the air flow F in a range.

在此，圖4A及圖4B係圖2的突出部122之剖視圖。圖4A係顯示沿著可撓性結構體114之延伸方向的突出部122之剖面，圖4B係顯示垂直面上的突出部122相對於可撓性結構體114之貫通方向的剖面。 Here, FIGS. 4A and 4B are cross-sectional views of the protrusion 122 of FIG. 2. 4A shows a cross section of the protrusion 122 along the extending direction of the flexible structure 114, and FIG. 4B shows a cross section of the protrusion 122 on a vertical plane with respect to the through direction of the flexible structure 114.

突出部122，係具有大致球形狀，且以貫通其中心的方式設置有貫通孔123。在貫通孔123，係***有電纜狀之可撓性結構體114。貫通孔123之內徑、與可撓性結構體114之外徑係以對應的方式所設定，且在被穿通至貫通孔123的可撓性結構體114上之既定位置固定有突出部122。 The protrusion 122 has a substantially spherical shape, and a through hole 123 is provided so as to penetrate through the center thereof. In the through hole 123, a cable-shaped flexible structure 114 is inserted. The inner diameter of the through hole 123 and the outer diameter of the flexible structure 114 are set in a corresponding manner, and a protrusion 122 is fixed at a predetermined position on the flexible structure 114 penetrated to the through hole 123.

雖然突出部122係將大致球形狀作為基本的構成，但是具有與可撓性結構體114之延伸方向交叉的氣體接受表面124。在本實施形態中，氣體接受表面124，係構成作為可撓性結構體114之延伸方向的垂直之平面。突出部122，係藉由具有如此的氣體接受表面124，而在氣體接受表面124接受管構件10之內部的氣流F，且有效率地獲得推進力。 Although the protrusion 122 has a substantially spherical shape as a basic configuration, it has a gas receiving surface 124 that intersects the extending direction of the flexible structure 114. In this embodiment, the gas receiving surface 124 constitutes a vertical plane as the extension direction of the flexible structure 114. The protruding portion 122 has such a gas receiving surface 124 to receive the air flow F inside the pipe member 10 at the gas receiving surface 124, and effectively obtain the propulsion force.

再者，雖然在圖2中係例示管構件10之內部的氣流F顯示一方向的情況，但是氣流F也可為相反方向 (氣流F之方向或強度也可與時間一起變化)。對應於此，突出部122係在貫通孔123之兩側具有一對氣體接受表面124。藉此，無關於管構件10之內部的氣流F之方向，都能從氣流F獲得推進力。 Furthermore, although FIG. 2 illustrates a case where the airflow F inside the pipe member 10 shows one direction, the airflow F may also be in the opposite direction. (The direction or intensity of air flow F can also change with time). Corresponding to this, the protrusion 122 has a pair of gas receiving surfaces 124 on both sides of the through hole 123. Thereby, regardless of the direction of the air flow F inside the pipe member 10, the propulsive force can be obtained from the air flow F.

具備如此之突出部122的可撓性結構體114，係相對於探傷感測器112而包含連接於氣流F之上游側的第一可撓性結構體114a、以及連接於氣流F之下游側的第二可撓性結構體114b。藉此，在探傷檢查裝置110係可藉由已設置於探傷感測器112之兩側的第一可撓性結構體114a及第二可撓性結構體114b遍及於整體地獲得均等的推進力，且能夠在管構件10之內部進行平滑的移動。 The flexible structure 114 having such a protrusion 122 includes a first flexible structure 114a connected to the upstream side of the airflow F and a first flexible structure 114a connected to the downstream side of the airflow F with respect to the flaw detection sensor 112 The second flexible structure 114b. Thereby, in the flaw detection inspection device 110, the first flexible structure 114a and the second flexible structure 114b that have been arranged on both sides of the flaw detection sensor 112 can obtain an equal propulsion force throughout the whole. , And can move smoothly inside the pipe member 10.

如圖1所示，具有上述構成的探傷檢查裝置110，係透過已連結於管構件10之端部的***夾具130，從外部朝向管構件10之內部***。在此，圖5係圖1的***夾具130之剖視圖。 As shown in FIG. 1, the flaw detection and inspection apparatus 110 having the above-mentioned structure is inserted from the outside toward the inside of the pipe member 10 through the insertion jig 130 connected to the end of the pipe member 10. Here, FIG. 5 is a cross-sectional view of the insertion jig 130 of FIG. 1.

***夾具130，係具有：本體部134，其是包含探傷檢查裝置110能夠通過內部的導入路徑132。在本體部134之一端側，係設置有用以連結於管構件10之端部的第一連結部136。第一連結部136，係包含能夠匹配於管構件10之端部的凸緣(flange)，且透過由彈性材料所構成之如O型環的封閉構件(未圖示)，構成能夠緊密地連結於管構件10之端部。 The insertion jig 130 has a main body 134 that includes an introduction path 132 through which the flaw detection and inspection device 110 can pass through. On one end side of the main body 134, a first connecting portion 136 for connecting to the end of the pipe member 10 is provided. The first connecting portion 136 includes a flange that can be matched to the end of the pipe member 10, and is configured to be tightly connected through a closing member (not shown) made of an elastic material such as an O-ring At the end of the pipe member 10.

在本體部134之另一端側，係設置有用以連結於從外部送入探傷檢查裝置110用之軟管構件138的第二 連結部140。在第二連結部140，係可覆蓋軟管構件138之端部，且從其外側藉由軟管帶(hose band)142所鎖緊固定，藉此構成能夠緊密地連結。 On the other end side of the main body 134, there is provided a second tube member 138 connected to the hose member 138 used for the inspection device 110 to be fed from the outside. 连接部140。 Linking section 140. The second connecting portion 140 is capable of covering the end of the hose member 138, and is locked and fixed by a hose band 142 from the outside, so that the structure can be tightly connected.

如圖1所示，在軟管構件138，係從外部藉由作業員***有探傷檢查裝置110。已***於軟管構件138的探傷檢查裝置110，係以透過***夾具130之導入路徑132，送入於管構件10的方式所構成。 As shown in FIG. 1, in the hose member 138, the flaw detection inspection apparatus 110 is inserted by the operator from the outside. The flaw detection and inspection device 110 inserted into the hose member 138 is configured to be fed into the pipe member 10 through the introduction path 132 of the insertion jig 130.

在此，在***夾具130，係具有：氣體供應管146，其是包含以與導入路徑132匯流之方式所構成的氣體供應路徑144。在氣體供應管146之一端側，係從氣體供應部150(參照圖1)，透過軟管構件152供應有氣體。因氣體供應部150係位於燃燒爐12之外部，故而軟管構件152係透過已設置於燃燒爐12之壁面14的開口部16，來連結氣體供應部150和氣體供應管146。 Here, the insertion jig 130 is provided with a gas supply pipe 146 including a gas supply path 144 configured to merge with the introduction path 132. On one end side of the gas supply pipe 146, gas is supplied from the gas supply part 150 (refer to FIG. 1) through the hose member 152. Since the gas supply part 150 is located outside the combustion furnace 12, the hose member 152 connects the gas supply part 150 and the gas supply pipe 146 through the opening 16 provided on the wall surface 14 of the combustion furnace 12.

氣體供應管146之另一端側，係與本體部134一體地構成，且在其內部，氣體供應路徑144係以與導入路徑132匯流的方式所構成。為此，已供應至氣體供應管146的氣體，係從氣體供應路徑144經過導入路徑132而被導引至管構件10。如此，在管構件10之內部，係形成有氣流F。 The other end side of the gas supply pipe 146 is formed integrally with the main body 134, and the gas supply path 144 is formed so as to merge with the introduction path 132 inside. For this reason, the gas that has been supplied to the gas supply pipe 146 is guided from the gas supply path 144 to the pipe member 10 through the introduction path 132. In this way, an air flow F is formed inside the pipe member 10.

再者，在氣體供應管146，係設置有用以調整來自氣體供應部150的氣體之供應量的調整閥154。 Furthermore, the gas supply pipe 146 is provided with an adjustment valve 154 for adjusting the amount of gas supplied from the gas supply unit 150.

如此，藉由***夾具130，可透過導入路徑132來***探傷檢查裝置110，並且從氣體供應管146供應有氣體，藉此能夠利用形成於管構件10之內部的氣流F，來進行探傷檢查裝置110之移動。雖然探傷檢查裝置110係藉由具有可撓性結構體114而柔軟地構成，但是管構件10之內部的探傷檢查裝置110之移動，係可以如上面所述地藉由利用從氣流F所獲得的推進力，沿著具有複雜形狀的管構件10平滑地進行。In this way, by inserting the jig 130, the flaw detection and inspection device 110 can be inserted through the introduction path 132, and gas is supplied from the gas supply pipe 146, whereby the flaw detection and inspection device can be performed using the air flow F formed inside the pipe member 10 110 of the move. Although the flaw detection and inspection device 110 is softly constructed by having a flexible structure 114, the movement of the flaw detection and inspection device 110 inside the pipe member 10 can be obtained by using the airflow F as described above. The propulsion force is smoothly performed along the pipe member 10 having a complicated shape.

又，探傷檢查系統100，也可具備用以計數探傷檢查裝置110對管構件10之***量的編碼器156。圖6A及圖6B係顯示圖1之探傷檢查系統100所具備的編碼器156之一例的示意圖。In addition, the flaw detection and inspection system 100 may include an encoder 156 for counting the insertion amount of the flaw detection and inspection device 110 into the pipe member 10. 6A and 6B are schematic diagrams showing an example of the encoder 156 included in the flaw detection inspection system 100 of FIG. 1.

編碼器156，係具備：一對旋轉構件158a、158b，其是構成能夠透過已設置於管構件10的管壁之一部分的開口部157，來接觸於通過管構件10之內部的探傷檢查裝置110。一對旋轉構件158a、158b係相互地對向，且以從兩側夾入探傷檢查裝置110的方式所配置。一對旋轉構件158a、158b，係藉由接觸於探傷檢查裝置110，伴隨管構件10之內部的探傷檢查裝置110之移動而旋轉，藉此來計數探傷檢查裝置110往管構件10之***量。The encoder 156 is provided with a pair of rotating members 158a, 158b, which are configured to be able to pass through an opening 157 provided in a part of the pipe wall of the pipe member 10 to contact the inspection device 110 passing through the inside of the pipe member 10. . The pair of rotating members 158a and 158b are opposed to each other, and are arranged so as to sandwich the flaw detection inspection device 110 from both sides. The pair of rotating members 158a and 158b are contacted with the flaw detection and inspection device 110 and rotate with the movement of the flaw detection and inspection device 110 inside the pipe member 10, thereby counting the insertion amount of the flaw detection and inspection device 110 into the pipe member 10.

在此，一對旋轉構件158a、158b，係彈性地彈壓於探傷檢查裝置110。為此，如圖6A所示，在探傷檢查裝置110當中之直徑比較大的突出部122通過時，係能藉由突出部來推寬一對旋轉構件158a、158b之間隔。另一方面，如圖6B所示，在探傷檢查裝置110當中之直徑比較小的可撓性結構體114通過時，一對旋轉構件158a、158b之間隔會變小。如此，藉由一對旋轉構件158a、158b之間隔相應於探傷檢查裝置110之直徑而變化，就能良好地確保一對旋轉構件158a、158b對探傷檢查裝置110之接觸狀態。Here, the pair of rotating members 158a and 158b are elastically pressed against the flaw detection and inspection apparatus 110. For this reason, as shown in FIG. 6A, when the protrusion 122 with a relatively large diameter in the flaw detection inspection device 110 passes, the distance between the pair of rotating members 158a and 158b can be widened by the protrusion. On the other hand, as shown in FIG. 6B, when the flexible structure 114 with a relatively small diameter in the flaw detection inspection device 110 passes, the interval between the pair of rotating members 158a and 158b becomes smaller. In this way, by changing the interval between the pair of rotating members 158a and 158b in accordance with the diameter of the flaw detection and inspection device 110, the contact state of the pair of rotating members 158a and 158b to the flaw detection and inspection device 110 can be ensured well.

回到圖1，探傷檢查系統100，係具備：分析裝置200，其是用以分析由已***於管構件10之探傷檢查裝置110所取得的檢查訊號，藉此來檢查管構件10。探傷檢查裝置110係一邊移動於管構件10之內部且一邊藉由探傷檢查裝置110而取得檢查訊號，該檢查訊號係透過可撓性結構體114中所包含的訊號電纜118(參照圖3)送至分析裝置200。Returning to FIG. 1, the flaw detection inspection system 100 is provided with an analysis device 200 for analyzing the inspection signal obtained by the flaw detection inspection device 110 inserted into the pipe member 10 to inspect the pipe member 10. The flaw detection and inspection device 110 moves inside the pipe member 10 while obtaining an inspection signal by the flaw detection and inspection device 110. The inspection signal is sent through the signal cable 118 (see FIG. 3) included in the flexible structure 114. To the analysis device 200.

分析裝置200，係藉由如電腦(computer)的運算處理裝置所構成，且構成能夠實施本發明之至少一實施形態的檢查方法。例如，分析裝置200，係藉由在如電腦的運算處理裝置，安裝(install)有能夠執行本發明之至少一實施形態的檢查方法的程式(program)所構成。在此情況下，能夠執行本發明之至少一實施形態的檢查方法的程式，也可藉由在如電腦的運算處理裝置讀取能夠讀取地記憶於既定之記憶媒體來安裝。The analysis device 200 is constituted by an arithmetic processing device such as a computer, and constitutes an inspection method capable of implementing at least one embodiment of the present invention. For example, the analysis device 200 is configured by installing a program capable of executing the inspection method of at least one embodiment of the present invention in an arithmetic processing device such as a computer. In this case, the program that can execute the inspection method of at least one embodiment of the present invention can also be installed by reading and storing in a predetermined storage medium in an arithmetic processing device such as a computer.

接著，針對使用了具有上述構成之探傷檢查系統100的檢查方法加以說明。圖7係依每一工序而顯示本發明之至少一實施形態的探傷檢查方法之流程圖。Next, an inspection method using the flaw detection inspection system 100 having the above-mentioned configuration will be described. FIG. 7 is a flowchart showing the flaw detection and inspection method of at least one embodiment of the present invention according to each process.

首先，對成為檢查對象的管構件10，安裝上述的***夾具130(步驟S1)。***夾具130，係藉由將其一端側連結於管構件10之端部，來安裝於管構件10(藉此形成有第一連結部136)。在第一連結部136中，係藉由使如O型環的封閉構件(未圖示)中介在與已設置於管構件10之端部的凸緣部之間，就可緊密地連結管構件10與***夾具130之間。First, the aforementioned insertion jig 130 is attached to the pipe member 10 to be inspected (step S1). The insertion jig 130 is attached to the pipe member 10 by connecting its one end side to the end of the pipe member 10 (thereby forming the first connecting portion 136). In the first connecting portion 136, by interposing a closing member (not shown) such as an O-ring with the flange portion already provided at the end of the pipe member 10, the pipe member can be tightly connected 10 and the insertion clamp 130 between.

接著，透過軟管構件152將氣體供應部150連接於已安裝在管構件10的***夾具130(步驟S2)。如圖1所示，因氣體供應部150係位於燃燒爐12之外部，故而可透過通過燃燒爐12之壁面14上所設置之開口部16的軟管構件152，連接於***夾具130之氣體供應管146。Next, the gas supply unit 150 is connected to the insertion jig 130 installed on the pipe member 10 through the hose member 152 (step S2). As shown in Fig. 1, since the gas supply part 150 is located outside the combustion furnace 12, it can be connected to the gas supply of the insertion jig 130 through the hose member 152 passing through the opening 16 provided on the wall 14 of the combustion furnace 12 Pipe 146.

接著，從氣體供應部150對***夾具130開始空氣之供應(步驟S3)。來自氣體供應部150之空氣供應，係藉由打開已設置於氣體供應管146的調整閥154而開始。藉此，已從氣體供應部150供應至***夾具130的空氣，就會從氣體供應路徑144經過導入路徑132而被導引至管構件10。如此，在管構件10之內部，係形成有氣流F。Next, the air supply unit 150 starts supplying air to the insertion jig 130 (step S3). The air supply from the gas supply part 150 is started by opening the adjustment valve 154 that has been installed in the gas supply pipe 146. Thereby, the air that has been supplied from the gas supply part 150 to the insertion jig 130 is guided from the gas supply path 144 to the pipe member 10 through the introduction path 132. In this way, an air flow F is formed inside the pipe member 10.

再者，往***夾具130之空氣供應量，係在接著的步驟S4中相應於應對被***於***夾具130的探傷檢查裝置110賦予的推進力而調整。如此的空氣供應量之調整，係藉由控制調整閥154之開啟度所進行。Furthermore, the air supply amount to the insertion jig 130 is adjusted in the following step S4 in response to the propulsion force given to the flaw detection and inspection device 110 inserted into the insertion jig 130. Such adjustment of the air supply amount is performed by controlling the opening degree of the adjustment valve 154.

接著，準備探傷檢查裝置110和分析裝置200，且將探傷檢查裝置110事先連接於分析裝置200(步驟S4)。在此，因分析裝置200，係具有比燃燒爐12之開口部16還小的尺寸，故而能夠透過開口部16從外部攜入於燃燒爐12之內部，且配置於作為檢查對象的管構件10之附近(燃燒爐12之內部)。Next, the flaw detection and inspection device 110 and the analysis device 200 are prepared, and the flaw detection and inspection device 110 is connected to the analysis device 200 in advance (step S4). Here, since the analysis device 200 has a size smaller than the opening 16 of the combustion furnace 12, it can be carried into the combustion furnace 12 from the outside through the opening 16, and is arranged in the pipe member 10 that is the inspection object. Near (inside the combustion furnace 12).

再者，分析裝置200之動作所需的電力，係從已設置於燃燒爐12之外部的電源部210透過電源電纜220所供應。電源電纜220，係以通過已設置於燃燒爐12之壁面14的開口部16之方式所設置。Furthermore, the electric power required for the operation of the analysis device 200 is supplied through the power cable 220 from the power supply unit 210 installed outside the combustion furnace 12. The power cable 220 is installed so as to pass through the opening 16 provided on the wall surface 14 of the combustion furnace 12.

接著，將探傷檢查裝置110***於***夾具130(步驟S5)。探傷檢查裝置110係在事先已連接於分析裝置200的狀態下，透過***夾具130之導入路徑132，送入於管構件10之內部。此時，因在管構件10之內部或導入路徑132，係藉由在步驟S3所供應來的空氣而形成有氣流F，故而探傷檢查裝置110係賦予有藉由氣流F所致的推進力。藉此，探傷檢查裝置110係可平滑地***於管構件10之內部。Next, the flaw detection inspection device 110 is inserted into the insertion jig 130 (step S5). The flaw detection and inspection device 110 is inserted into the pipe member 10 through the introduction path 132 of the insertion jig 130 in a state where it has been connected to the analysis device 200 in advance. At this time, since the air flow F is formed in the interior of the pipe member 10 or the introduction path 132 by the air supplied in step S3, the flaw detection and inspection device 110 is given a propulsion force by the air flow F. Thereby, the flaw detection and inspection device 110 can be smoothly inserted into the inside of the pipe member 10.

接著，一邊使探傷檢查裝置110在管構件10之內部移動，且一邊實施藉由探傷檢查裝置110所為的檢查(步驟S6)。管構件10之內部的探傷檢查裝置110之移動，係藉由調整對管構件10之空氣供應量所進行。如此的空氣供應量之調整，係藉由控制調整閥154之開啟度所進行。Next, while moving the flaw detection and inspection apparatus 110 inside the pipe member 10, the inspection by the flaw detection and inspection apparatus 110 is performed (step S6). The movement of the flaw detection and inspection device 110 inside the pipe member 10 is performed by adjusting the air supply amount to the pipe member 10. Such adjustment of the air supply amount is performed by controlling the opening degree of the adjustment valve 154.

探傷檢查裝置110中的測定資料，係隨時發送至分析裝置200，且儲存。在分析裝置200中，係取得來自探傷檢查裝置110之測定資料，並且參照圖6取得上面所述的編碼器156之計數值，且相互地建立關聯關係並予以管理。藉此，分析裝置200，係能夠判別探傷檢查裝置110中的各個測定資料已在管構件10之某個位置被取得。然後，分析裝置200，係藉由分析如此所管理的測定資料，來實施管構件10之各個位置的檢查。The measurement data in the flaw detection inspection device 110 is sent to the analysis device 200 at any time and stored. In the analysis device 200, the measurement data from the flaw detection inspection device 110 is obtained, and the count value of the encoder 156 described above is obtained with reference to FIG. 6, and the correlation relationship is established and managed. Thereby, the analysis device 200 can determine that each measurement data in the flaw detection inspection device 110 has been acquired at a certain position of the pipe member 10. Then, the analysis device 200 performs inspection of each position of the pipe member 10 by analyzing the measurement data managed in this way.

接著，判定是否已針對已事先設定於管構件10的既定之檢查範圍完成步驟S6中的檢查(步驟S7)。在並未針對檢查範圍完成檢查的情況下(步驟S7：「否」)，可藉由將處理返回至步驟S6，來對其餘的檢查範圍實施檢查。在已針對檢查範圍完成檢查的情況下(步驟S7：「是」)，結束一系列的檢查方法(「結束(END)」)。Next, it is determined whether the inspection in step S6 has been completed for the predetermined inspection range set in the pipe member 10 in advance (step S7). In the case where the inspection has not been completed for the inspection range (step S7: "No"), the inspection can be performed on the remaining inspection ranges by returning the process to step S6. When the inspection has been completed for the inspection range (step S7: "Yes"), a series of inspection methods are ended ("END (END)").
