塑料復合管(guan)(guan)與鋼(gang)絲(si)網骨架的連(lian)接(jie)采用電(dian)熱(re)熔(rong)(rong)接(jie)和法蘭連(lian)接(jie)。電(dian)熱(re)熔(rong)(rong)接(jie)是(shi)將復合管(guan)(guan)插入(ru)電(dian)熱(re)熔(rong)(rong)接(jie)管(guan)(guan)件，使(shi)嵌入(ru)管(guan)(guan)件內(nei)表面的電(dian)熱(re)絲(si)通電(dian)加熱(re)。首(shou)先，熔(rong)(rong)化(hua)管(guan)(guan)道(dao)(dao)內(nei)表面以(yi)產生(sheng)熔(rong)(rong)體(ti)，熔(rong)(rong)化(hua)并膨脹(zhang)并填(tian)充(chong)管(guan)(guan)道(dao)(dao)間隙(xi)，直到管(guan)(guan)道(dao)(dao)表面也產生(sheng)熔(rong)(rong)體(ti)。這兩種熔(rong)(rong)化(hua)物相互熔(rong)(rong)合。冷(leng)卻成(cheng)型(xing)后，管(guan)(guan)道(dao)(dao)與管(guan)(guan)道(dao)(dao)緊密連(lian)接(jie)為一個(ge)整(zheng)體(ti)。

電熱熔(rong)合(he)連接的特(te)點：

電(dian)熱(re)熔接技術(shu)施工方便(bian)。快速的可(ke)(ke)進(jin)行連接、安裝和組裝，并可(ke)(ke)進(jin)行統一焊接。

焊接可(ke)靠(kao)性好。與其(qi)他連接方法(fa)相(xiang)比(bi)，強度和密度更好。

保持(chi)管(guan)道內壁光滑(hua)，不影響流動面積。
