Description

用于管道系统安装和维修的方法和设备
技术领域
本发明涉及根据独立权利要求1和19的前序部分所述的用于管道系统安装和维修的方法和系统,该管道系统包括由可焊接的塑料材料制成的至少两个管道。
背景技术
管道系统用在许多不同的传输情况并且用于在管道内部传输不同种类的气体、液体、流体、媒介、材料(materia)或物质。使管道彼此功能性附接的需要非常重要,不仅保护管道系统内部的传输物免于泄漏,而且免受来自外界的污染或其他损害。
一些管道系统倾向于埋藏在地下,这引起大的应力。由于引起材料膨胀以及收缩的温度变化,将会对管道产生机械冲击。管道系统还暴露于可能穿透管道系统并使钢管道腐蚀的水或水分,久而久之这会引起泄漏从而需要维修。管道系统通常铺设在墙壁等下方,使得在泄漏的情况下得到接近必须挖出的受损管道系统的机会是困难且成本高的。
即使管道系统位于地面上或上方,使管道彼此功能性附接的需要还是非常重要。虽然可以以相对高的精确度定位泄漏点,但是维修各种管道系统的成本将会很高。因此,在新安装以及进行维修时,提供高质量和高强度的安装、接合是至关重要的。从长远来看,质量不合格或者在最坏的情况下组装方面的系统缺陷可能会破坏管道系统的整体经济性。
目前在市场上存在接合管道的许多方法。经验表明与其他解决方案相比,采用焊接的接头的方法通常在长期具有优势。然而,焊接并不是完全没有问题。
一种方法用于由可焊接的聚合物材料制成的管道并且包括使用焊接带(导电带)。两个管道要彼此连接。一条焊接带绕每个管端设置并且被由可焊接的聚合物材料制成的套管覆盖,该套管跨过两个管道端部之间的间距,与每个管道端部交叠。套管被加热,然后在每个管道端部上收缩。带连接至电气装置并且通过使用稳定加热方式(resistingheating)来加热该带。带被加热,然后使管道的塑料和套管的塑料两者均熔化。然后塑料将会混合。在电子装置被断开或关断时,熔化的混合塑料将会冷却并且在进行焊接时将套管与每个管道接合。
电子装置连接至带的两端。带的端部或连接至带的电极被弯曲并且设置在管道的外侧,通过套管中的缝伸出,并且带端部或电极要被放置在一起的区域实际上并不是那么精确。在管道和套管的区域中,带端部(电极)之间存在间隙。由于在形成到带端部的电连接的区域中,没有使塑料完全地且受控地熔化,所以存在焊接的临界点。在该区域中带端部被稍微分开并且塑料实际上并没有被热处理。这将引起可能会发生泄漏的焊接薄弱点。
发明内容
本发明的一个目的是提供能够在安装以及维修管道系统1时以简单、安全且有效的方式实现可靠的防漏焊接使得形成良好的接头、焊接部分的方法和设备。
该目的通过具有在权利要求1的特征部分中所呈现的区别技术特征的方法以及具有在权利要求19的特征部分中所呈现的区别技术特征的设备来实现。
在从属权利要求中可以找到示例性实施方案。

具体实施方式
方法
本发明涉及用于接合管道系统1的方法。管道系统1包括要被彼此连接的至少两个管道2。管道2由可焊接的塑料、聚合物、材料制成。参照图1。
管道系统1可以被制造成用于传输加压或未加压的不同种类的气体、液体、流体、媒介、材料或物质。管道系统1可以具有不同设计,管道2可以具有不同构造。管道2可以包括被置于管道2内部的内管道3,管道2为外管道2。外管道2与内管道3之间的间隙可以填充有隔热材料4。参照图2。在下面的描述中,措词“管道2”意指将与套管焊接的管道,并且如果管道系统被隔热则“管道2”是“外管道2”。
如在区域供暖或区域供冷管道系统中,通常采用隔热管道系统来传输流动的加热或冷却液体、媒介,并且隔热管道系统具有用于传输所述流动的液体、媒介的钢管道。然后将钢管道埋(embedded)在通常由聚氨酯(PUR)泡沫制成的隔热物中,并且在外部存在使其不受水分影响的外壳、由可焊接的塑料材料(通常为聚乙烯)制成的外管道。管道系统在工厂内被分部分地制成外管道2、内管道3和隔热物4,然后将外管道2、内管道3和隔热物4外送至安装位置。这种类型的隔热管道系统还可以用于传输例如油、LNG以及化学品。
本方法包括下述步骤:将由可焊接的塑料、聚合物、材料制成的套管5配合在两个管道2之间的间距处,套管5与每个管道端部2a和2b交叠。参照图1和图2。套管5将被附接两个管道2,并且在焊接之后套管5将成为管道系统1的管道2的一部分。套管5具有长度A,其超过相对的管道端部2a和2b之间的间距B,使得套管5与管道端部2a和2b交叠成给定的延伸部分C。参照图3。套管5整体制造并且在直径上与外管道2相比较大。
本方法还包括下述步骤:围绕管道2中的一个的端部设置导电带6,导电带6可渗透熔化的塑料,通过将带6的端部6a和6b设置成彼此交叠来将带6的端部6a和6b彼此连接,将套管5配合在管道2(管道端部2a或2b)和带6上方且抵靠管道2(管道端部2a或2b)和带6,与管道2(管道端部2a或2b)交叠,并且覆盖带6。参照图3。
本方法还包括:在给定时间段上给带6施加电流并且由此将带6在预定时间加热至预定温度,并且将带6与管道2和套管5的与带6邻接的塑料表面融合以形成焊接接头,该焊接接头具有与带6的宽度对应的宽度D并且围绕管道2且在套管5内部完全实现。带6和焊接部分的宽度小于或类似于套管交叠部分C。参照图1至图3。
由于带端部6a和6b被设置成彼此交叠,所以管道2和套管5两者的塑料将都在管道2和套管5周围被加热,并且焊接将在周围完全进行,即使在带交叠区也是如此。本方法能够在安装和维修管道系统1时实现可靠的防漏焊接,从而以简单、安全且有效的方式形成了良好的接头。
焊接管道2的先前的方式可能引起塑料区域的不均匀加热并且引起烧穿,上述先前的方式使用带并且特定地给带的端部施加电流,所述端部通过套管中的缝伸出。由于电流在带中传输的距离长,所以带中的电流分布可能变化,由此在不同区域以不同方式影响带的温度。这将会导致焊接部分具有不利的性质。为了避免该故障,本发明的方法包括围绕一个外管道2的端部设置导电带6并且将至少两个导体7连接至带6,使得可以将带6附接至给带6施加电流的电气装置8。参见图1。然后电流将从至少两个位置分布至带6上并且传输距离将会较短,使得更好地加热带6以及管道2和套管5的塑料。
本方法包括将至少两个导体7连接至带6,将至少两个金属片7a连接至带6。可以通过经由在带6与片7之间设置附加带7b来将每个导体7(每个片7a)连接至带6来完成该连接。还可以完成在带6与每个金属片7a之间连接隔热装置(insulatingdevice)7c。使用金属片7a将使得可以以容易且公知的电引导方式连接电流,使用附加带7b确保在附加区域中焊接将以受控的方式完成,得到被增强的焊接点,并且使用隔热装置7c将提供控制焊接部分的布置的可能性。参照图3。
将至少两个导体7连接至带6包括将导体7设置在围绕带6的固定预定位置处,以使围绕带6的电流以及围绕管道2和套管5的热均匀分布。在使用两个导体7的情况下,本方法包括将导体7沿着带6以彼此成约180°的布置设置并且将导体7沿着带6以相对于电气装置8成约90°的布置设置。所述设置中的“约”的描述意指对于不同的情况设置可以是靠得更近或离得更远。设置的重点在于并非电流分布所涉及的所有装置都被设置在一个区域中的一个点。参照图1。该设置将得到沿着带6的电流的良好分布。
关于接合或维修管道1的工作通常在具有不同气候条件的户外进行。例如,管道2可能在顶部上由于光照而具有与在设置成背离太阳的底部上相比更高的温度。在将电流施加至具有两个电流入口的带6时,使用彼此成180°位移几乎水平设置的导体7使得加热在温度不同的顶部和底部的区域中的管道2和套管5的塑料所需的效果将由于温度不同的区域中的不同电阻而进行自调节。在管道2的被太阳加热的顶部区域中,带6中的电阻与在底部上相比较高并且电流将选择电阻较低的底部,较多的电流将经过管道的底部上的带6中的路径。由于电阻差,这样一来,电流将处于需要其的区域,并且在管道2周围的加热情况将相同。
将套管5配合在管道2的端部2a或2b的上方和周围且抵靠管道2的端部2a或2b包括:加热套管5(其为由通过添加热而被控制的可收缩材料制成的收缩套管5),由此减小套管5直径,使得套管5的内侧与管道2的外侧接触。然后带6将被固定在管道2与套管5之间的适当位置。
将套管5配合在管道2的端部的上方和周围且抵靠管道2的端部包括:在将套管5配合在管道的端部2a或2b上方和周围且抵靠管道2的端部2a或2b的部分处给套管5上和周围施加压力。可以通过使用作用于套管6上和周围的压力工具9来实现给套管5上和周围施加压力。参照图1。这将确保带6将固定在管道2与套管5之间的适当位置。
使用压力工具9包括使用套在套管5周围的夹带9a并且将夹带9a的自由端连接至拉紧装置10,该拉紧装置10用于拉紧套管5周围的夹带9a并且通过夹带9a使套管5压抵管道2。这未在附图中示出。
本方法可以包括穿过套管5钻孔以用于对所形成的焊接部分进行压力测试。如果管道系统1包括外管道2和内管道3,则该孔可以用于以泡沫填充接头以完成隔热。必须在孔中设置塞子以对孔进行密封。这未在附图中示出。
电源可能是个问题。很可能有非常大的电力损耗,原因是电流变换可能是必需的并且电流必须在相对长的距离上传导以到达焊接位置。可获得的电源不总是最优的。因此本发明的另一目的是实现可靠的电流供应以用于在隔热管道系统的安装及维修期间的焊接,使得形成良好的接头。
为此,本发明包括下述步骤:采用具有准谐振变换器B2的电源转换器B1来产生将连接至带6的电流。参照图4。
本方法还可以包括下述步骤:采用连接至两个不同相的两个串联连接的电源转换器B1并且经由两个准谐振变换器B2的同步操作使输出电压相加,以便于产生将连接至带6的电流。参照图5和图6。
必须在足够长的时期内提供热,以使带6的区域(焊接区)中的温度变得足够高以形成机械上坚固且密封的高质量的焊接。如果提供不足的热,则焊接区的部分将不会到达期望温度并且将不会产生期望的熔化,这将会引起低质量的焊接。与此相对,如果提供过多的热,则情况是存在管道的端部以及套管中的材料将由于管道变形而受损。因此,重要的是仔细控制热的提供,使得在特定时间段提供足够的热,使得在管道2的端部与套管5之间形成高质量的焊接。
因此本发明的另一目的是提供一种可以以简单有效且安全的方式进行可靠的温度控制并且控制给带6(焊接区)供热的方法,使得形成高质量的焊接。为此,本方法包括:
在加热带6之前测量带区域的初始环境温度T0,测量跨带6的电压UL;测量施加至带6的电流IL
在加热带6之前计算带6的初始电阻R0
以交变或直流的方式将电流提供给带6;
基于电压和测量的电流持续地计算带6的电阻R,计算电阻的变化ΔR;以及
基于电阻的改变计算带6的温度增加ΔΤ并且通过将焊接部分的初始环境温度T0与带6的温度增加ΔΤ相加来计算焊接部分的温度TW
在图7至图9中,示出了布置在焊接区中的被制造来根据本方法工作的装置(焊接装备)A1-A3的三个实施方案。
一旦焊接过程结束,焊接的接头必须在可以移除电气装置8、焊接装备和压力装置9(夹带9a和拉紧装置10)之前冷却,以便于避免对刚焊接的接合部的损害。冷却阶段是焊接的耗时部分。在制造的环境中,重要的是实现高效率,并且期望在高焊接质量的情况下,以省时的方式执行焊接。
因此,本发明的另一目的是提供一种使得可以在焊接过程结束时对焊接的接头处的冷却过程进行高效且可靠的温度监测的方法。为此,本方法包括:
在焊接过程结束之后执行测量过程,测量过程包括从指示器单元11给带6提供电流Ip,
通过指示器单元11确定带6的得到的依赖于温度的参数Sp,Sp的值存储在指示器单元11中,
在预定的时间间隔之后,从指示器单元11给带提供另外的电流脉冲Ip,确定带中的参数Sp,并且将Sp的值存储在指示器单元11中,
指示器单元11监测并评估参数Sp的值或参数Sp的值的相对变化,
重复测量过程直至Sp到达平稳值或者Sp的相对变化到达预定水平,
在指示器单元11指示冷却过程结束的情况下,信号装置发出焊接装备可以从焊接区移除的信号。参照图10。

设备12包括支承装置13,其用于在使用压力工具9时(在拉紧装置11附接至夹带9a时)帮助设备12设置在套管5的外侧上。支承装置13包括邻近支承装置的以相互平行且相互间隔的关系布置的引导辊,其中辊之间的间距远小于管道的直径。夹带9a的端部从在引导辊之间形成的套延伸。支承装置13包括凹的邻接表面,以提供与朝外弯曲的管道表面的良好邻接。至少邻接表面由电绝缘材料制成。在附图中未详细示出该支承装置13。
电源可能是个问题。很可能有非常大的电力损耗,原因是电流变换可能是必需的并且电流必须在相对长的距离上传导以到达焊接位置。可获得的电源不总是最优的。因此,本发明的另一目的是实现可靠的电流供应以用于在隔热管道系统1的安装及维修期间的焊接,使得形成良好的接头。
