管道加熱器是一種對物質預先加熱的節能設備，它安裝在物質設備之前，實現對物質直接加溫，使其在高溫中循環加熱作用，最終達到節約能源的目的。它廣泛應用于重油，瀝青，清油等燃料油的預先加熱的場合。

管道加熱(re)(re)(re)器(qi)有(you)本體和控(kong)制(zhi)系統兩部(bu)分(fen)組成(cheng)(cheng)，發熱(re)(re)(re)元(yuan)件(jian)采用(yong)(yong)不銹鋼(gang)鋼(gang)管做保護套管，高溫(wen)(wen)電(dian)(dian)阻(zu)合金絲，結晶(jing)氧化鎂粉，經壓縮工藝成(cheng)(cheng)型，控(kong)制(zhi)部(bu)分(fen)采用(yong)(yong)先進的數(shu)字電(dian)(dian)路，集成(cheng)(cheng)電(dian)(dian)路觸發器(qi)、高反壓可控(kong)硅等組成(cheng)(cheng)可調測溫(wen)(wen)、恒(heng)溫(wen)(wen)系統，保證了電(dian)(dian)加熱(re)(re)(re)器(qi)的正常運行。

通(tong)(tong)過加熱(re)(re)使桶(tong)內(nei)的(de)液體、凝(ning)固(gu)物(wu)容(rong)易取出，如(ru)桶(tong)內(nei)的(de)粘接(jie)劑、油(you)脂、柏油(you)、油(you)漆(qi)、石蠟和(he)各(ge)種(zhong)樹(shu)脂原料需(xu)要加熱(re)(re)也(ye)可通(tong)(tong)過桶(tong)體加熱(re)(re)，使其(qi)補充熱(re)(re)量。此裝置不受季節(jie)影響可常年(nian)使用(yong)。加熱(re)(re)器(qi)表面安裝傳感器(qi)，通(tong)(tong)過溫(wen)度調節(jie)直接(jie)控制溫(wen)度。
