消(xiao)防電伴(ban)熱(re)(re)帶-旭誠(在線咨詢)-天津消(xiao)防電伴(ban)熱(re)(re)帶

冬季北方好多地(di)區已經受到寒潮影(ying)響(xiang)，溫(wen)度下(xia)降的比較(jiao)明顯，北京、天(tian)津等地(di)甚至下(xia)起(qi)來了大雪，受到氣溫(wen)的影(ying)響(xiang)，好多室外水管道(dao)都(dou)已經結冰上凍，馬路上發現好多市政維修工人搶(qiang)救路政管道(dao)。

室外露天水管道里面的介質主要是水，冬季主要是因為水結冰，保持水介質在零度以上就可以控制不結冰，所以對電伴熱帶的溫度要求不是太高。我們伴熱帶廠家一般會推薦客戶使用低溫系列電伴熱帶進行保溫防凍，低溫系列一般是自限溫電伴熱帶，它的工作溫度為65℃，可以維持管道內介質不發生，液體一直處于流動狀態，可以起到很好的保溫效果。

　隨著電伴熱帶在管道和設備中防凍的效果非常明顯，現在好多生產型企業都已經用上了電伴熱系統保溫，已經慢慢的普及開來，保溫效果沒有任何問題，往往好多客戶考慮的是伴熱帶的使用壽命，電伴熱帶是使用壽命更加產品型號的不同，一般在10到15年左右，如果使用的好，壽命更長，所以壽命也不需要很擔心，我們廠家施工的好多大型化工企業正常使用都沒有任何維護費用，非常讓客戶放心。
