瀝青是由不同分子量的碳氫化合物及非金屬衍生物組成的黑褐色的復雜混合物,它主要是從煤和石油中提取出來的高粘度有機液體的一種,呈液態,是一種防水防潮和防腐的有機膠凝材料,屬于易燃易爆的化學物質,那么電伴熱系統具體在瀝青管道上怎么應用呢?
電(dian)(dian)伴(ban)(ban)(ban)熱(re)(re)系(xi)統是利用(yong)電(dian)(dian)能轉換為熱(re)(re)能的伴(ban)(ban)(ban)熱(re)(re)保(bao)溫(wen)(wen)方式,清潔環保(bao),伴(ban)(ban)(ban)熱(re)(re)效率高(gao),將電(dian)(dian)伴(ban)(ban)(ban)熱(re)(re)帶(dai)貼敷在管(guan)道(dao)表面安裝即可。瀝(li)青(qing)(qing)管(guan)道(dao)由于冬季溫(wen)(wen)度過低會(hui)出現凍(dong)結現象(xiang),需(xu)要(yao)用(yong)到電(dian)(dian)伴(ban)(ban)(ban)熱(re)(re)保(bao)溫(wen)(wen)系(xi)統,而瀝(li)青(qing)(qing)管(guan)道(dao)處在易(yi)燃(ran)易(yi)爆區(qu)域,選擇(ze)的電(dian)(dian)伴(ban)(ban)(ban)熱(re)(re)帶(dai)型(xing)號也(ye)需(xu)要(yao)是防(fang)爆防(fang)腐(fu)型(xing)的電(dian)(dian)伴(ban)(ban)(ban)熱(re)(re)帶(dai)。根據要(yao)求可以選擇(ze)中溫(wen)(wen)防(fang)爆防(fang)腐(fu)型(xing)自限溫(wen)(wen)伴(ban)(ban)(ban)熱(re)(re)帶(dai),它(ta)可以自動限制(zhi)加熱(re)(re)的溫(wen)(wen)度,并且可以隨(sui)意裁剪(jian),交叉重疊(die)使用(yong)。
電伴熱帶(dai)(dai)型號比較(jiao)多,除了自限溫伴熱帶(dai)(dai)外,還有恒(heng)功率電伴熱帶(dai)(dai)、MI加熱電纜,普通(tong)場合,蒸汽吹掃(sao)環境電伴熱帶保溫(wen)均可以使用。
