西北地區分布著眾多的油田，是石油的主要產地，但是由于早晚溫差的原因，管線里面的介質會出現流速慢和凍堵的情況，石油管線也是如此。所以需要為其安裝電伴熱系統等保溫方式來維持管線里面的溫度。

  電(dian)伴(ban)熱(re)(re)系統防(fang)凍(dong)保溫(wen)(wen)是將(jiang)電(dian)伴(ban)熱(re)(re)帶(dai)敷設在管線的表面(mian)，通過電(dian)能轉換為熱(re)(re)能，補(bu)償管道(dao)的熱(re)(re)損失，維持管道(dao)介(jie)質所(suo)需要的溫(wen)(wen)度。管道(dao)電(dian)伴(ban)熱(re)(re)帶(dai)保溫(wen)(wen)方(fang)式讓石油管線防(fang)凍(dong)變的簡單起(qi)來。石油管(guan)道(dao)(dao)防(fang)(fang)凍保溫(wen)(wen)(wen)(wen)可以使用防(fang)(fang)腐防(fang)(fang)爆型的自限(xian)溫(wen)(wen)(wen)(wen)電(dian)(dian)伴熱(re)帶(dai)(dai)，該電(dian)(dian)伴熱(re)帶(dai)(dai)具有溫(wen)(wen)(wen)(wen)度(du)(du)(du)自我(wo)調節的功能。當管(guan)道(dao)(dao)內介質(zhi)溫(wen)(wen)(wen)(wen)度(du)(du)(du)高于設定的溫(wen)(wen)(wen)(wen)度(du)(du)(du)，電(dian)(dian)伴熱(re)帶(dai)(dai)會自動關閉(bi)電(dian)(dian)源；當管(guan)道(dao)(dao)內介質(zhi)溫(wen)(wen)(wen)(wen)度(du)(du)(du)低于設定的溫(wen)(wen)(wen)(wen)度(du)(du)(du)，電(dian)(dian)伴熱(re)帶(dai)(dai)會自動開(kai)啟(qi)電(dian)(dian)源，如此循環(huan)往(wang)復，維(wei)持管(guan)道(dao)(dao)介質(zhi)需(xu)求(qiu)溫(wen)(wen)(wen)(wen)度(du)(du)(du)。當然(ran)如果(guo)現場環(huan)境(jing)比較復雜，溫(wen)(wen)(wen)(wen)度(du)(du)(du)要(yao)求(qiu)也特別高，則需(xu)要(yao)使用恒(heng)功率電(dian)(dian)熱(re)帶(dai)(dai)，甚至(zhi)是(shi)高溫(wen)(wen)(wen)(wen)鎧(kai)裝MI加熱(re)電(dian)(dian)纜。

  電(dian)伴熱(re)是一(yi)種節能、安(an)全、環保(bao)、快速的防凍保(bao)溫(wen)(wen)系統(tong)，它的使(shi)用場(chang)合也(ye)比較廣(guang)泛，如(ru)工(gong)業場(chang)合管道、罐體保(bao)溫(wen)(wen)，民用場(chang)合水管防凍，以(yi)及建筑物融雪化冰等。如(ru)果您有伴熱(re)保(bao)溫(wen)(wen)方面的需求可(ke)以(yi)隨(sui)時咨詢我們。
