Description
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.

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
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
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
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
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
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
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
圖3係圖2的可撓性結構體114之A-A剖視圖。可撓性結構體114,係具備:張力構件(tension member)116,其是配置於中心部;及至少一條訊號電纜118,其是設置於張力構件116之徑向外側;以及保護層120,其是設置於至少一條訊號電纜118之徑向外側。張力構件116,係包含由例如不鏽鋼等之金屬材料所構成的線材116a,且其表面是藉由聚胺基甲酸酯(polyurethane)等之皮膜116b所覆蓋而構成。訊號電纜118,係包含用以傳遞探傷感測器112與分析裝置200(參照圖1)之間的各種訊號的訊號電纜(例如同軸電纜),且以包圍張力構件116的方式所配置。保護層120,係由PVC等之絕緣性材料所形成,用以保護已配置於內側的張力構件116及訊號電纜118。
FIG. 3 is an A-A cross-sectional view of the
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
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
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
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
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
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
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
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
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。

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
***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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
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
如以上所說明,依據上述實施形態,藉由對***有探傷檢查裝置110的管構件10供應氣體,就可以藉由在管構件10之內部所產生的氣流來一邊使探傷檢查裝置110移動且一邊實施檢查。使用了如此之氣流的探傷檢查裝置110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。
[產業上之可利用性]As described above, according to the above-mentioned embodiment, by supplying gas to the
