管徑377*7玻璃鋼外護架空聚氨酯保溫管

聚氨酯發泡保(bao)溫(wen)管(guan)種類劃分；

一、聚乙烯夾克(ke)外套(tao)管

聚乙烯外(wai)套管采(cai)用(yong)高密度聚乙烯材(cai)料制成，具(ju)有很(hen)高的(de)機械強度和的(de)耐腐蝕性，它能(neng)保護管材(cai)在運輸、安(an)裝及使用(yong)過(guo)程(cheng)中不受外(wai)界因素引起的(de)破(po)壞。

二、聚(ju)氨酯預(yu)制保(bao)溫管

管材中敷(fu)設(she)伴熱(re)電(dian)(dian)纜(lan)(lan)可以避免由于管道凍(dong)結而影響(xiang)管網(wang)運行(xing)。敷(fu)設(she)伴熱(re)電(dian)(dian)纜(lan)(lan)的管材，規格尺寸結構*與普通保溫管相同，特(te)制的伴熱(re)電(dian)(dian)纜(lan)(lan)緊巾鋼管外壁與之平行(xing)敷(fu)設(she)在管材中，利用點熱(re)通過鋼管加熱(re)介質。剛通電(dian)(dian)瞬間(jian)電(dian)(dian)纜(lan)(lan)發(fa)熱(re)功(gong)(gong)率zui大，隨著溫度長高(gao),電(dian)(dian)纜(lan)(lan)中PTC記憶材料(liao)電(dian)(dian)阻逐漸(jian)增大，因而工(gong)作電(dian)(dian)流和電(dian)(dian)熱(re)功(gong)(gong)率也逐漸(jian)減小，直至(zhi)發(fa)熱(re)功(gong)(gong)率補償系統(tong)的熱(re)損(sun)失,使(shi)系統(tong)溫度處于穩(wen)定狀態時止。當環境溫度降低有(you)降低趨勢的時候，電(dian)(dian)纜(lan)(lan)功(gong)(gong)率自動(dong)增大，自動(dong)補償損(sun)失，使(shi)系統(tong)在新的溫度下處于平衡。這種補償加熱(re)方(fang)式是高(gao)效節(jie)能的。
