夹克保温管怎么安装或预装电伴热?

信息来源:皖缆集团 浏览次数:857 发布时间:2017-04-05

    夹克保温管不建议安装或预装电伴热,因为夹克保温管常用于埋地、高密封性或无高保温要求场合。它的外保温和防护层是出厂前预装好的,到达现场后拼接即可。

 

夹克保温管的电伴热安装


    如果在出厂前预装电伴热,会给现场管道施工带来困难,且电伴热接线也是个难题。若管道安装完再来铺设电伴热,起不到多大的保温效果;毕竟电伴热与管道之间间隔了较厚的保温棉和防护层。电伴热与被伴热管道平行贴合才能最大发挥其效果;即使因设计要求,中间隔层也不能太厚。
    有些夹克保温管采用了电伴热预装,那是针对特殊要求的,且较短距离管道的使用。反之,在需要采用电伴热来维持工艺温度或防冻保温,就不适合选择夹克保温管。
