旭誠瑞侃電伴(ban)(ban)熱(re)帶(圖)-天(tian)津(jin)防(fang)爆(bao)電伴(ban)(ban)熱(re)帶-防(fang)爆(bao)電伴(ban)(ban)熱(re)帶

　電伴熱帶應用于油田井筒保溫選擇什么型號呢，油井使用電伴熱有利于在井筒中保持較高的溫度，可以在保證節約環保的情況下，維持井筒溫度在結蠟溫度之上。在選擇的電伴熱產品類型上，合適的電伴熱產品型號既可以節約能源，又可以延長電伴熱系統的壽命。通過對現場環境分析和油田井筒本身的特性，如果自限溫電伴熱帶可以達到要求，則建議使用自限溫電伴熱帶。這種型號的電伴熱帶具有PTC特性，可以實現自限溫的功能。因此，只要用戶做好電伴熱系統的外保溫，通電開啟后即可不用再為管道防凍的問題擔憂，可以保證電伴熱系統能源的合理使用。
