Abstract
Description
本發明係關於一種塗覆管件內表面之方法及於管件內表面上具有塗層之管件。 The invention relates to a method for coating the inner surface of a pipe fitting and a pipe fitting with a coating on the inner surface of the pipe fitting.
於工業中使用之各種類型之習知管件(諸如水管、氣體管件、熱傳送管等)的內表面需能抗腐蝕及抵抗在管件與於其中流動之流體之間的化學反應。此可藉由利用諸如氟樹脂層之樹脂層塗覆該等管件之內表面來達成。 The inner surfaces of various types of conventional pipe fittings used in industry (such as water pipes, gas pipe fittings, heat transfer pipes, etc.) need to be resistant to corrosion and chemical reactions between the pipe fittings and the fluid flowing therein. This can be achieved by coating the inner surface of the pipes with a resin layer such as a fluororesin layer.
塗覆或內襯氟樹脂通常尤其被應用在可能暴露至高度腐蝕性化學品的化學、醫藥及半導體廠中。 Coating or lining fluororesin is often used especially in chemical, medical and semiconductor plants that may be exposed to highly corrosive chemicals.
氟樹脂材料可呈粉狀粉末形式,藉此其包含樹脂本身或作為與如著色劑、除酸劑或填充劑之添加劑混合的化合物。將氟樹脂材料塗覆至管件之內表面的方法可藉由使用靜電粉末噴槍將靜電粉末塗料施覆於管件之內表面上,隨後加熱管件以使粉末熔融來形成塗層而進行。然而,此方法一次僅可產生僅具有一層膜的管件。若需要若干層膜,則需進行若干分開的塗覆以達成目標膜厚度。此減慢管件製造時間。此外,反電離(back ionization)係此方法中的一項問題,因電荷的過度累積會阻止靜電粉末進一步沉積於具有現有塗層之管件的表面。 The fluororesin material may be in the form of a powdery powder, whereby it contains the resin itself or as a compound mixed with additives such as coloring agents, acid scavengers, or fillers. The method of applying the fluororesin material to the inner surface of the pipe can be performed by applying an electrostatic powder coating to the inner surface of the pipe using an electrostatic powder spray gun, and then heating the pipe to melt the powder to form a coating. However, this method can only produce pipes with only one film at a time. If several layers of film are required, several separate coatings are required to achieve the target film thickness. This slows down the pipe fitting manufacturing time. In addition, back ionization is a problem in this method, because the excessive accumulation of electric charge prevents the electrostatic powder from further depositing on the surface of the pipe with the existing coating.
另一方法係迴轉內襯(Roto-lining)方法,其涉及於基板之內表面上引入顆粒狀氟樹脂材料及加熱管件,使得顆粒狀氟樹脂材料熔融及容許經由良好受控的旋轉及加熱製程均勻地流動。由於流動不僅取決於基板之旋轉,而且亦取決於諸如加熱均勻度、氟樹脂材料與基板間之交互作用的因素,因此先天上很難控制熔融顆粒狀氟樹脂材料的確切流動。一般而言,迴轉內襯方法適用於厚度大於1mm的內襯或塗層,並不適用於厚度小於1mm的較薄內襯或塗層。 Another method is the Roto-lining method, which involves introducing granular fluororesin materials and heating pipes on the inner surface of the substrate, so that the granular fluororesin materials are melted and allowed to go through a well-controlled rotation and heating process Flow evenly. Since the flow depends not only on the rotation of the substrate, but also on factors such as heating uniformity and the interaction between the fluororesin material and the substrate, it is inherently difficult to control the exact flow of the molten particulate fluororesin material. Generally speaking, the rotary lining method is suitable for linings or coatings with a thickness of more than 1mm, and not suitable for thinner linings or coatings with a thickness of less than 1mm.
在兩種前述方法中,要獲得均勻厚度之內塗層而不發生內襯缺陷係有困難的,因很難控制靜電粉末噴槍之噴霧及熔融顆粒狀氟樹脂材料的流動。 In the two aforementioned methods, it is difficult to obtain a uniform thickness of the inner coating without lining defects, because it is difficult to control the spray of the electrostatic powder spray gun and the flow of the molten particulate fluororesin material.
回應於前述問題/困難,已進行各種技術發展。舉例來說,已使用在彎曲及焊接前將氟樹脂粉末塗覆於金屬平板上來獲得具有內表面塗層的管狀管件。然而,存在因使用焊接技術而引起的負面影響。經受焊接的部件會經歷高於氟樹脂內襯材料之熱分解溫度的溫度。需要對其中之氟樹脂內襯材料已因高溫而分解的受影響部件進行修改。此外,氟樹脂的分解導致釋放出會對人體造成風險的有害氣體。 In response to the aforementioned problems/difficulties, various technological developments have been made. For example, fluororesin powder is coated on a metal flat plate before bending and welding to obtain a tubular pipe with an inner surface coating. However, there are negative effects caused by the use of welding technology. The parts subjected to welding will experience a temperature higher than the thermal decomposition temperature of the fluororesin lining material. It is necessary to modify the affected parts in which the fluororesin lining material has decomposed due to high temperature. In addition, the decomposition of fluororesin leads to the release of harmful gases that pose a risk to the human body.
如日本專利申請案號JP1992-352689中所描述的另一方法涉及用單片氟樹脂膜內襯貯槽的內表面,其中氟樹脂膜沒有任何重疊。氟樹脂膜的末端邊緣彼此相鄰,使得邊緣形成對接接頭。隨後將密封膜置於對接接頭上方以將其覆蓋。使用涉及在密封膜上施加熱及壓力的技術(例如,熱封或焊接)來密封對接接頭。然而,此製程需要額外加熱及熔融密封膜。此等額外步驟使得很難控制塗 層的厚度均勻度並會降低塗覆貯槽內表面之製程的效率。 Another method as described in Japanese Patent Application No. JP1992-352689 involves lining the inner surface of the tank with a single piece of fluororesin film, where the fluororesin film does not have any overlap. The end edges of the fluororesin film are adjacent to each other so that the edges form a butt joint. The sealing film is then placed over the butt joint to cover it. The butt joint is sealed using techniques that involve the application of heat and pressure to the sealing film (e.g., heat sealing or welding). However, this process requires additional heating and melting of the sealing film. These additional steps make it difficult to control the thickness uniformity of the coating and reduce the efficiency of the process of coating the inner surface of the tank.
另一方面,日本專利第3954120號描述一種涉及將管狀內襯烴基材料抽拉成金屬管及藉由供應至內襯材料中之壓縮空氣將管狀內襯壓至管之內表面上的方法。此方法可應用於諸如聚乙烯及聚丙烯的烴樹脂,但不可適用於具有較高屈服點強度的其他樹脂(諸如氟樹脂)。不同於烴樹脂,氟樹脂在其塑性變形之前需要較高壓力。因此,若將此方法應用於塗覆氟樹脂,則在製程中將需要顯著的壓力,其會影響製程之效率或導致安全風險。 On the other hand, Japanese Patent No. 3954120 describes a method involving drawing a tubular lining hydrocarbon-based material into a metal pipe and pressing the tubular lining onto the inner surface of the pipe by compressed air supplied to the lining material. This method can be applied to hydrocarbon resins such as polyethylene and polypropylene, but it is not applicable to other resins (such as fluororesins) with higher yield point strength. Unlike hydrocarbon resins, fluororesins require higher pressure before they are plastically deformed. Therefore, if this method is applied to coating fluororesin, significant pressure will be required in the manufacturing process, which will affect the efficiency of the manufacturing process or cause safety risks.
根據本揭示內容之一實例的一態樣,提供一種塗覆管件內表面之方法。該方法可包括將內襯材料在管件之長度上螺旋形地施壓於管件之內表面上。可向經施壓之內襯材料施加熱,以於管件之內表面上形成一層塗層。 According to an aspect of an example of the present disclosure, a method for coating the inner surface of a pipe is provided. The method may include applying the lining material spirally to the inner surface of the pipe over the length of the pipe. Heat can be applied to the pressurized lining material to form a coating on the inner surface of the pipe.

The coating has a lining material spirally attached to the inner surface of the pipe over the length of the pipe.

本揭示內容係關於一種用來塗覆管件內表面之方 法。此方法包括:a)將內襯材料在管件之長度上螺旋形地施壓於管件之內表面上;及b)加熱經施壓之內襯材料,以使內襯材料作為塗層附著於管件內表面上。 The present disclosure relates to a method for coating the inner surface of pipe fittings. This method includes: a) applying lining material spirally on the inner surface of the pipe over the length of the pipe; and b) heating the pressed lining material so that the lining material is attached to the pipe as a coating On the inner surface.
內襯材料可係細長條狀物,且該方法可進一步包括在將內襯材料在管件之長度上螺旋形地施壓於管件之內表面上時,使細長條狀物之邊緣的一部分重疊。 The lining material may be an elongated strip, and the method may further include overlapping a part of the edge of the elongated strip when the lining material is helically pressed on the inner surface of the pipe over the length of the pipe.
於管件之內表面上具有藉由該方法塗覆之塗層的管件具有一塗層,其係在管件之長度上螺旋形地附著於管件內表面上的內襯材料。 The pipe fitting with the coating applied by the method on the inner surface of the pipe fitting has a coating, which is a lining material that is spirally attached to the inner surface of the pipe fitting over the length of the pipe fitting.
圖1繪示可如何進行該方法的一實例。在圖1中,顯示經塗覆內襯材料104的管件100。內襯材料104係呈細長條狀物之形式。內襯材料係螺旋形地塗覆於管件100之內表面上,使得細長條狀物之邊緣的一部分在管件100之長度上彼此重疊。內襯材料104係自定位於管件100內部之分配器105分配並於定位於管件100之內表面上之壓輥103與管件100之間饋送。壓輥103將內襯材料104施壓於管件之內表面上及壓輥102施壓與管件100之內表面相對之管件的外表面。 Figure 1 shows an example of how this method can be performed. In Fig. 1, a
在本實例中,管件100的形狀實質上為管狀或圓柱形,且具有適於在管件中輸送諸如流體之物體的中空核心。管件100的橫截面為環形,其實質上為圓形。然而,當明瞭其他適用於用內襯材料104塗覆內表面之管件100的形狀亦係可能的。例如,管件100可具有實質上的四邊形或多邊形橫截面。對於此等非管狀形 狀,管件100之內表面的轉角可經修圓以利於經由壓輥103的彎曲或圓形表面來塗覆。壓輥103可經機械組態以到達非管狀管件100的轉角,且視需要定向為傾斜以螺旋形地塗覆管件100的內表面。在此情況,另一壓輥102可經組態以與壓輥103共同作用來施加壓力。 In this example, the
在本實例中,管件100係由金屬(例如,鋁或銅)製成。然而,當明瞭取決於意欲輸送通過管件之流體或物體,管件可由不同類型的材料(包括金屬、塑膠或複合材料)製成。 In this example, the
內襯材料104可包括黏著至管件100之內表面的黏性表面,或內襯材料104可由可黏著至管件100之內表面的黏性材料製成。在內襯材料104係由黏性材料製成的情況中,可能在將內襯材料104加熱至特定溫度時,內襯材料104的黏著性質被活化。包含羧基官能基的黏性材料係適合用作內襯材料104或內襯材料104上之黏性表面之具有黏著性質之材料的一實例。 The
在本實例中,內襯材料104為氟樹脂膜。可用於形成氟樹脂膜之氟聚合物的實例包括乙烯四氟乙烯(ETFE)及全氟烷氧基烷烴(PFA)。如於專利公開案US7112640B2中所描述之氟共聚物亦係可用於形成氟樹脂膜之合適聚合物的實例。在其他組態中,內襯材料104可由多於一層氟樹脂膜組成。與管件100之內表面直接接觸的氟樹脂膜層可經組態為具有用於黏著至管件100之內表面之黏著性質的黏性表面。包含羧基官能基的氟樹脂膜係適合用作與管件100之內表面直接接觸之內襯材料104之具有黏著性質之材料的一實例。 In this example, the
在本實例中,提供兩個壓輥102及103且其串聯移 動。具有兩個壓輥102及103提供抗衡力,其在待塗覆之管件100之內表面的一區域或部分上施加扣緊或夾緊壓力。然而,在另一組態中可能僅提供壓輥103,但在此情況,須固持管件100以防止管件100因壓輥103將內襯材料104施壓於管件100之內表面上而移動。 In this example, two
壓輥102及103之形狀各實質上為圓柱形。各壓輥102及103係可繞旋轉軸旋轉。在另一組態中,可能僅壓輥103係可旋轉及壓輥102不旋轉。 The shapes of the
存在若干用來於管件之內表面上進行內襯材料之螺旋形塗覆的方法。在本實例中,起初將內襯材料104的起始端夾於壓輥103與管件100之內表面之間。另一壓輥102與壓輥103串聯移動,以提供於待塗覆之管件100之內表面之區域或部分上施加扣緊或夾緊壓力的抗衡力。在塗覆製程期間,壓輥103的旋轉拉動自分配器105饋送之內襯材料104及於管件100之內表面上施壓內襯材料104。分配器105包括內襯材料104之捲筒,且當其用完時需重新載入新的內襯材料104捲筒。 There are several methods for spiral coating of the lining material on the inner surface of the pipe. In this example, initially, the starting end of the
當明瞭如文中所述在管件之內表面上進行內襯材料之螺旋形塗覆具有就對於塗覆層之厚度之較佳控制及降低內襯缺陷發生而言的優點。不同於習知之迴轉內襯方法,在本實例中內襯材料104之厚度不限於1mm或以上。 It should be understood that the spiral coating of the lining material on the inner surface of the pipe as described in the text has advantages in terms of better control of the thickness of the coating layer and reduction of the occurrence of lining defects. Unlike the conventional rotary lining method, the thickness of the
螺旋形地塗覆管件100之內表面的一個實例係使壓輥103保持固定及使管件100連續旋轉並在內襯材料104經壓輥103施壓時使管件100在沿管件100之長度之方向中移動。壓輥103將旋轉並在管件100旋轉及移動時拉動自分配器105饋送之內襯材 料104。或者,在另一實例中,在內襯材料104正被施壓且管件100保持固定的同時,壓輥103可環繞管件100之內表面之圓周連續旋轉及在沿管件100之長度之方向中移動。壓輥103將旋轉並在壓輥103移動時拉動自分配器105饋送之內襯材料104。在又另一實例中,在內襯材料104正被施壓及在不旋轉管件100下使管件100在沿管件100之長度之方向中移動的同時,壓輥103可環繞管件100之內表面之圓周連續旋轉而不使壓輥103在沿管件100之長度之方向中移動。在再一實例中,在內襯材料104正被施壓及在不使管件100在沿管件100之長度之方向中移動下旋轉管件100的同時,壓輥103可在沿管件100之長度之方向中移動而不使壓輥103環繞管件100之內表面之圓周旋轉。在所有此等實例中,若存在之另一壓輥102將與壓輥103串聯移動。 An example of spirally coating the inner surface of the
壓輥103可旋轉及於管件100之內表面上方滾動,或者,壓輥103可藉由替代地在壓輥103保持固定的同時移動管件100來旋轉。為螺旋形地塗覆管件100之內表面,將壓輥102及103設置於相對於沿管件之長度方向之縱軸成一傾斜角。稍後將提供壓輥102及103相對於沿管件之長度方向之縱軸之傾斜角的細節。 The
在本實例中,在內襯材料104為在施加熱時黏著至管件100之類型時,經施壓之內襯材料104係藉由加熱作為塗層附著至管件100之內表面。施加至經施壓之內襯材料104的熱降低經施壓之內襯材料104的黏度及使其充分地黏性而附著至管件100之內表面。 In this example, when the
應注意內襯材料104之加熱不應完全熔融經施壓之內襯材料104或管件100。否則,在整個管件100之內表面在內襯 材料104之塗層厚度中會有不期望的變化。向經施壓之內襯材料104短期間施加熱,例如,少於1分鐘(其適用於本實例),有助於阻止經施壓之內襯材料104完全熔融。此外,在本實例中,將該經施壓之內襯材料104加熱至介於較內襯材料104之熔點低60℃至較內襯材料104之熔點高10℃之間之溫度。此係將內襯材料104軟化至內襯材料104可黏著至管件100之內表面及/或在實施內襯材料之重疊之情況中黏著至已存在於管件100之內表面上之另一內襯材料之程度的期望溫度範圍。此外,由於內襯材料104之熔點的溫度甚低於焊接製程(其涉及熔融金屬)中所使用之溫度,因此前述溫度範圍將不會熔融管件100或分解內襯材料104。因此,不同於一些涉及金屬焊接之用來塗覆管件之內表面的習知技術,本文所述方法具有內襯材料104將不會被加熱至將使內襯材料104分解之金屬焊接溫度的優勢。 It should be noted that the heating of the
內襯材料104之加熱可在該內襯材料104藉由加熱壓輥103及/或壓輥102而被施壓的同時進行。或者,在管件100係由諸如金屬之導熱性材料製成的情況中,管件100可替代地被加熱,以使內襯材料104黏著至管件100之內表面。在另一組態中,壓輥103及/或壓輥102及管件100皆可被加熱。在又另一組態中,內襯材料104可經施壓及黏著至管件100之內表面,隨後於內襯材料104上進行加熱,以確保其黏著至管件100之內表面。 The heating of the
壓輥103可用非黏性材料塗覆或製造,以防止經加熱的經施壓內襯材料104附著至壓輥103。該等非黏性材料的實例包括氟聚合物諸如聚四氟乙烯(PTFE)及其類似物。熱之施加至內襯材料104可透過,例如,壓輥102及/或103、及/或管件100的感應 加熱來完成。 The
在本實例中,在內襯材料104於管件100之長度上螺旋形地施壓於管件100之內表面上時,內襯材料104之邊緣的一部分重疊以形成重疊部分106。內襯材料104可經重疊使得內襯材料104之重疊部分106的厚度較內襯材料104之非重疊部分的厚度大20%至100%。稍後將論述重疊部分106可如何達成此厚度的更多資訊。取決於欲實施的重疊程度而定,管件100中之內襯材料的厚度可介於100μm至500μm之間。此厚度可藉由具有多於一層內襯材料104來達成。內襯材料104之此厚度範圍適用於工業中用來輸送金屬腐蝕性流體的金屬管件。應注意內襯材料104之此重疊係可選的,且可視情況來提供。例如,在管件100之內表面上之經施壓內襯材料104之塗層意欲阻止管件100中之內容物與管件100之內表面直接接觸的情況中,內襯材料104之塗層應覆蓋管件100的整個內表面而不留下任何暴露管件100之內表面的間隙。重疊部分106有助於確保不存在未被內襯材料104覆蓋之管件100的暴露內表面。此有利地減少內襯缺陷的發生並提供內襯材料104對管件100之內表面的更牢固附著。 In this example, when the

明確言之,圖5F顯示沿圖4中之線A-A之內襯材料104之橫截面圖550的一實例。在圖5F之實例中的內襯材料104具有1層。此層可為氟樹脂膜層。此層104黏著至管件100之內表面。在本實例中,內襯材料104具有兩個相對邊緣部分。各邊緣部分成錐形以形成具有作為內襯材料104之終止端之一尖端的三角形橫截面。圖5F顯示參照圖4說明之內襯材料104之非重疊部分112之寬度110。圖5F亦顯示參照圖4說明之包括重疊部分106之寬度之內襯材料104的寬度111。非重疊部分112之厚度及重疊部分106之厚度可藉由調整待黏著至管件100之內表面之內襯材料104之相鄰層間的距離來改變。在圖5F中,值得注意地,非重疊部分112係由構成內襯材料104的1層所組成,而重疊部分106係由不到1 層的內襯材料104所組成。在此情況,重疊部分106之厚度較非重疊部分112之厚度小。 Specifically, FIG. 5F shows an example of a

圖6顯示參照先前圖所說明之分配兩層或更多層氟樹脂膜以形成內襯材料104之設備及方法的一實例。在圖6中,第一分配器121分配一層氟樹脂膜123及第二分配器122分配一層氟樹脂膜124。雖然說明氟樹脂膜,但當明瞭亦可使用由其他適宜材料製成之膜來形成內襯材料104。在第一及第二分配器121及122 之下游存在導輥125,用來將氟樹脂膜123及124之層引導至一對導輥126。可相應地將更多分配器及導輥添加至圖6之設置來形成具有多於兩層的內襯材料104。該對導輥126將氟樹脂膜123及124放置成彼此接觸。於通過導輥126後,氟樹脂膜123及124形成將構成內襯材料104的多層膜127。在本實例中,多層膜127中之個別的氟樹脂膜123及124彼此未永久附著,而係彼此相鄰堆疊。 FIG. 6 shows an example of the apparatus and method for distributing two or more fluororesin films to form the
在該對導輥126之更下游存在複數個導輥128。導輥128係用來引導多層膜127,以致將多層膜127置於兩個壓輥129及130之間。然後將多層膜127饋送於圖1之壓輥103與圖1中所示之管件100之內表面之間,以將管件100之內表面塗覆多層膜127。當於製程期間向多層膜127施加熱以使內襯材料104螺旋形地塗覆至管件100之內表面時,多層膜127之層將彼此黏著,且面向管件100之內表面的其中一個層將黏著至管件100之內表面。 There are a plurality of
可使用圖6之設置來獲得在相較於如參照先前圖所述之非重疊部分112之厚度超過0%至100%範圍內之如參照先前圖所述之重疊部分106的厚度。然而,須調整該設置,使得經分配的一或多個層將以將提供形成重疊部分106之部分所需之延伸部分的方式放置成彼此接觸。若該等層皆以相同寬度起始,則將需要修整一側上之該等層的過剩邊緣,使得僅該等層的一側具有形成重疊部分106之部分所需之延伸部分。 The setting of FIG. 6 can be used to obtain the thickness of the overlapping
圖7顯示用來在饋送之前將圖6之多層膜127自圖6之壓輥129及130引導至導輥131,以致將多層膜127置於圖1之壓輥103與圖1之管件100之內表面之間之設置的一實例。圖7係自一端透視至管件100中的視圖,以致可看見管件100的圓周(在 此情況,圓形)。較佳地,導輥131包括經組態以使得能夠調整多層膜127於壓輥103與管件100之內表面之間饋送之角度的可調整接頭(諸如可調整萬向接頭或球形接頭)。在本實例中,多層膜127於壓輥103與管件100之內表面之間饋送之角度係與參照圖2至4所描述之傾斜角α相同。 Fig. 7 shows a method for guiding the

參照圖8A及圖8B,圓錐輥802係安裝至一軸,使得圓錐輥802可繞軸804之縱軸旋轉。軸804具有各別安裝至自安裝塊805延伸之一對細長支撐件806的兩相對端。圓錐輥802係經設置成使多層膜127以適當角度轉向至壓輥103與管件100之內表面之間。在本實例中,多層膜127於壓輥103與管件100之內表面之間饋送之適當角度係與參照圖2至4所描述之傾斜角α相同。 8A and 8B, the tapered
圖9繪示圖1之管件100的透視圖且進一步繪示圖1之壓輥102及103之位置可如何固定於管件100內部。圖9中顯示支撐設備900。支撐設備900包括壓輥103、輥支撐件905、可延伸軸904、輥支撐件906、另一輥907、導輥支撐件903、導輥129及130、及支撐軸902。待定位於管件100內之壓輥103係固定至輥支撐件905之一端。明確言之,壓輥103係可旋轉地安裝至支撐件905,使得壓輥103可旋轉。支撐件905之另一端係附接至可延伸軸904之一端。可延伸軸904之另一端係透過輥支撐件906附接至輥907。壓輥103及輥907係位在支撐設備900的相對端且皆經設置成於管件100之內表面上施加壓力。可延伸軸904可經機械調整,使得支撐設備900自壓輥103於管件100之內表面上施加壓力及施壓於內襯材料104上之點至相對輥907接觸塗滿管件100之內表面之內襯材料104或管件100之內表面之點的長度,配合管件100之直徑。壓輥102係以使得其將於藉由壓輥103塗覆之管件100之內表面上方接觸管件100之外表面的方式安裝於管件100之外側, 並與壓輥103串聯移動。 FIG. 9 is a perspective view of the
可延伸軸904可包括諸如彈簧之偏壓機制,以施力於位在彼此相對端的壓輥103及輥907上。壓輥103及輥907繼而施加壓力於管件100之內表面上之內襯材料104或管件100之內表面上。 The
導輥支撐件903自在支撐設備900中間之可延伸軸904之位置正交地延伸。壓輥129及130固定至導輥支撐件903。支撐軸902自與導輥支撐件903在可延伸軸904之位置正交地延伸之方向相對的端延伸。支撐軸902之長度係可調整。 The
支撐軸902可延伸較管件100之長度長的長度至在管件100之外部或外側的固定位置,以固定支撐設備900之位置。在螺旋形塗覆期間管件100移動及壓輥103保持固定的情況中,支撐設備900需固定於定位。 The supporting
在管件100保持於相同位置及壓輥103移動穿越管件100的另一組態中,支撐軸902可附接至致動器(未示於圖9),以使支撐設備900滾動至待於管件100內塗覆的不同位置。 In another configuration where the
在另一實例中,在壓輥103可環繞管件100之內表面之圓周旋轉的情況下,可延伸軸904可附接至能夠旋轉支撐設備900的旋轉致動器,其繼而沿管件100之圓周旋轉壓輥103。 In another example, where the
支撐件905及/或可延伸軸904可經組態為用來加熱壓輥103的加熱裝置,其繼而加熱內襯材料104。或者,壓輥102可係替代地經加熱的一者。在另一組態中,壓輥102及103兩者可能通過加熱裝置一起被加熱。 The
內襯材料104之分配及/或引導及饋送可以使得除了 導輥將內襯材料104引導及饋送至壓輥103與管件100之內表面之間之位置外,內襯材料104將不會與設置之組件或元件接觸的方式,完全於管件100內進行。在其他組態中,分配器(例如121及122)可能定位於管件100外部,及如文中所述之導輥係在管件100內部。亦有可能一些導輥係在外部及一些導輥係在管件100內部。組態係取決於導輥如何經佈署以將內襯材料104引導至壓輥103與管件100之內表面之間的位置。 The distribution and/or guiding and feeding of the
