塑料復合(he)管(guan)(guan)與鋼絲網骨架的(de)連(lian)接采用電(dian)(dian)(dian)熱(re)熔(rong)(rong)接和法蘭(lan)連(lian)接。電(dian)(dian)(dian)熱(re)熔(rong)(rong)接是(shi)將復合(he)管(guan)(guan)插入電(dian)(dian)(dian)熱(re)熔(rong)(rong)接管(guan)(guan)件(jian)，使嵌入管(guan)(guan)件(jian)內表面的(de)電(dian)(dian)(dian)熱(re)絲通電(dian)(dian)(dian)加熱(re)。首先，熔(rong)(rong)化管(guan)(guan)道(dao)內表面以產(chan)生(sheng)熔(rong)(rong)體(ti)(ti)，熔(rong)(rong)化并(bing)膨(peng)脹(zhang)并(bing)填充(chong)管(guan)(guan)道(dao)間隙，直到(dao)管(guan)(guan)道(dao)表面也(ye)產(chan)生(sheng)熔(rong)(rong)體(ti)(ti)。這兩種熔(rong)(rong)化物相互熔(rong)(rong)合(he)。冷(leng)卻成型后，管(guan)(guan)道(dao)與管(guan)(guan)道(dao)緊(jin)密連(lian)接為一個(ge)整體(ti)(ti)。

電熱(re)熔合連接的特(te)點：

電熱熔接技術施工方便。快速的可進(jin)行連接、安裝(zhuang)和組裝(zhuang)，并可進(jin)行統一焊接。

焊接(jie)可靠性好。與其他(ta)連接(jie)方法相比，強(qiang)度和密度更(geng)好。

保持管道內壁(bi)光滑(hua)，不(bu)影響流動面積。
