熱熔和電熔是塑料管熔接的常用方法。通過熱熔機對加熱板進行加熱、銑削和加熱兩個要焊接的PE管材，熔化PE管的端口、用專用工具進行壓合、連接兩種PE管材的方法。大口徑pe管適用于這種方式的熱熔。電熔是采用專用熔合管套，PE管件是特殊的熱(re)(re)熔(rong)管配(pei)件(jian)，管件(jian)裝有電熱(re)(re)絲連(lian)接(jie)外接(jie)柱，電加熱(re)(re)熔(rong)化后，完成(cheng)連(lian)接(jie)，施(shi)工方(fang)便，穩定性好，人工成(cheng)本低，但管套價格高，適合小口徑管。

翻邊觀察
pe給水管(guan)的(de)(de)翻(fan)邊是在管(guan)道焊接過程中通(tong)過擠壓形成的(de)(de)，通(tong)常稱(cheng)為內(nei)翻(fan)和(he)翻(fan)邊，翻(fan)邊的(de)(de)質(zhi)量也影響到PE管(guan)道的(de)(de)流(liu)量效率，過大的(de)(de)翻(fan)邊也容易產生(sheng)結垢，造成管(guan)道內(nei)微生(sheng)物的(de)(de)滋生(sheng)，在排水工程中產生(sheng)淤積，降低水流(liu)效率。
pe給(gei)水(shui)管(guan)(guan)翻邊(bian)高度不一(yi)致(zhi)的(de)原因是(shi)給(gei)水(shui)管(guan)(guan)水(shui)平不正、不均(jun)勻(yun)、采暖面積(ji)不均(jun)勻(yun)，必須進行重(zhong)熔。在以往的(de)PE給(gei)水(shui)管(guan)(guan)道施(shi)工中(zhong)，目(mu)前(qian)還沒(mei)有很好的(de)處理(li)內部翻邊(bian)的(de)方法。恒興管(guan)(guan)理(li)行業(ye)在此總結(jie)了造成(cheng)PE水(shui)管(guan)(guan)不合格翻邊(bian)的(de)一(yi)些原因：
法蘭太小：吸(xi)熱時間不(bu)夠，焊(han)接機架(jia)行程不(bu)夠
翻邊太大：吸熱時(shi)間太長，PE原料熔化過多
翻邊錯位：PE管(guan)不固定水，PE管(guan)熔斷器不切平
