    • This invention concerns a method for joining or repairing a pipe system (1) that comprises a least two pipes (2) made of weldable plastic material comprising fitting a sleeve (5) made of weldable plastic material the distance between the two pipes (2), the sleeve (5) having a length A that exceeds the distance B between the mutually opposing pipes (2), such as to overlap each pipe end (2a, 2b) to a given extent C. The method has the working steps; placing an electrically conductive band (6) around one of the pipes (2), the band (6) having two ends (6a, 6b); connecting the band ends (6a, 6b)) to each other by placing the band ends (6a, 6b) overlapping each other; fitting the sleeve (5) over and against the pipe (2) and the band (6), and applying an electric current to the band (6) over a given period of time, thereby heating the band (6) to a determined temperature for a determined time and fusing the band (6) with the plastic surfaces of the pipe (2) and the sleeve (5) lying in abutment therewith to form a welding joint being fully executed around the pipe (2) and inside the sleeve (5). The invention also concerns an apparatus (12) to be used when working according to the method.
    • 本发明涉及一种连接或修理管道系统(1)的方法,该管道系统(1)包括由可焊接塑料材料制成的至少两个管道(2),包括由可焊接塑料材料制成的套筒(5),两个管道(2)之间的距离 套筒(5)的长度A超过相互相对的管道(2)之间的距离B,例如使每个管端(2a,2b)重叠到给定的程度C.该方法具有工作步骤; 在所述管道(2)中的一个周围放置导电带(6),所述带(6)具有两个端部(6a,6b); 通过使带端(6a,6b)彼此重叠,将带端(6a,6b)彼此连接) 将套筒(5)安装在管道(2)和带(6)上并靠近管道(6),并在给定的时间段内向带(6)施加电流,从而将带(6)加热到确定的温度 确定时间并将带(6)与管(2)的塑料表面和与其邻接的套筒(5)熔合,以形成围绕管(2)和套筒内部完全执行的焊接接头( 5)。 本发明还涉及根据该方法工作时要使用的装置(12)。
