专业预制直埋聚氨酯保温管定制-哪里有预制直埋聚氨酯保温管厂家
供热直埋管聚氨酯和保温直埋管敷设方式与传统的地沟及架空敷设相比,具有诸多优点。这也正是聚氨酯保温直埋管在我国
供热工程上得以迅猛发展的内在动力。
   关键词:聚氨酯保温直埋管 集中供热
  一、聚氨酯保温直埋管的优点
  1.降低工程造价。据有关部门测算,双管制供热管道,一般情况下可以降低工程造价的25%(采用玻璃钢做保护层)和10%(采用高密度聚乙烯做保护层)左右。
  2.热损耗低,节约能源。由于直埋管采用聚氨酯硬质泡沫塑料进行保温,其导热系数为:λ=0.013—0.03kcal/m·h·oc,比其他过去常用的管道保温材料低得多,保温效果提高4~9倍。再有其吸水率很低,约为0.2kg/m2。吸水率低的原因是由于聚氨酯泡沫的闭孔率高达92%左右。低导热系数和低吸水率,加上保温层和外面防水性能好的高密度聚乙烯或玻璃钢保护壳,改变了传统地沟敷设供热管道“穿湿棉袄”的状况,大大减少了供热管道的整体热损耗,热网热损失为2%,小于国际10%的标准要求。

3.防腐,绝缘性能好,使用寿命长。直埋保温管由于聚氨酯硬质泡沫保温层紧密地粘结在钢管外皮,隔绝了空气和水的渗入,能起到良好的防腐作用。

直埋聚氨酯保温管:高密度聚乙烯保护层 预制成一定壁厚的黑色(黄色)塑料管材,其作用一是保护聚氨酯保温层免遭机械硬物破坏,二是防腐防水。
聚氨酯发泡保温管道是以高功能聚醚多元醇组合料和多次氰酸酯为原料经化学反应发泡而成。
聚氨酯发泡保温管道具有容重轻、强度高、绝热、隔音、阻燃、耐寒、防腐、不吸水、施工简便快捷等优异特点,已成为石油、化工、电力、建筑、运输、冷藏等工业部门绝热保温、防水堵漏、密封等不可缺少的产品.
厂家直销价,可订做各种型号,质优价廉,量大更优惠。真诚期待与您合作!高效节能,应用广泛。
