PVC管設備關鍵,管(guan)(guan)(guan)材與管(guan)(guan)(guan)件(jian)銜(xian)接均選用(yong)熱熔(rong)(rong)(rong)銜(xian)接方(fang)法，不允(yun)許(xu)在(zai)管(guan)(guan)(guan)材和(he)管(guan)(guan)(guan)件(jian)上直接套絲、與金(jin)屬(shu)管(guan)(guan)(guan)道及用(yong)水器銜(xian)接有必(bi)要(yao)(yao)運用(yong)金(jin)屬(shu)嵌件(jian)的管(guan)(guan)(guan)件(jian)。熱熔(rong)(rong)(rong)銜(xian)接施工有必(bi)要(yao)(yao)運用(yong)本公司供給的熔(rong)(rong)(rong)接設備，以保證熔(rong)(rong)(rong)接質量。手提式熔(rong)(rong)(rong)接設備適用(yong)小(xiao)口徑(jing)(jing)管(guan)(guan)(guan)及體系最終(zhong)銜(xian)接，臺車式熔(rong)(rong)(rong)接機(ji)適用(yong)于大口徑(jing)(jing)管(guan)(guan)(guan)預裝置銜(xian)接。施工后須經試(shi)壓(ya)檢驗后方(fang)能封(feng)管(guan)(guan)(guan)和(he)運用(yong)。PVC管(guan)(guan)(guan)設備首要(yao)(yao)選用(yong)熱熔(rong)(rong)(rong)管(guan)(guan)(guan)件(jian)，熔(rong)(rong)(rong)接時刻和(he)壓(ya)力欠好把握(wo)，技(ji)術隨機(ji)性較大，在(zai)熱熔(rong)(rong)(rong)推接過(guo)程中易發(fa)作堆(dui)料(liao)然后減(jian)小(xiao)通徑(jing)(jing)，并使(shi)熔(rong)(rong)(rong)接處變成不規則的缺(que)點區，發(fa)作應力會集，影響PVC管(guan)(guan)(guan)道體系的長時間(jian)功(gong)能。

PVC自身的微觀布局決議了PVC耐疾速開裂才能差，因而，PVC膠管在歐洲被制止用于燃氣供給。而鋁塑管運用的聚乙烯的疾速裂紋傳遞有近20年的研討，且PAP的五層布局（聚乙烯/粘結劑/鋁/粘結劑/聚乙烯），將聚乙烯和鋁銜接成一個全體，不存在疾速開裂的風險。環保PVC管在10攝氏度以下就會變脆，在5攝氏度以下的溫度時就會變的很脆。這是由PVC的物理性質決議，其資料無法戰勝。在冬天要注意PVC的運用安全性，避免PVC管材在運用設備前因為溫度過低而被跌傷碰傷，保證管道設備的質量。
