聚氨酯保温管的强大优势

发布日期:2018-07-24 作者: 点击:

只要管道内部水质处理好,据国外资料介绍,。防腐,绝缘性能好,使用寿命长。预制聚氨酯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。同时它的发泡孔都是闭合的,吸水性很小。高密度聚乙烯外壳,玻璃钢外壳均具有良好的防腐,绝缘和机械性能。因此,工作钢管外皮很难受到外界空气和水的侵蚀。只要管道内部水质处理好,据国外资料介绍,预制聚氨酯直埋保温管的使用寿命可达50年以上,比传统的地沟敷设,架空敷设使用寿命高3~4倍。

为了满足管道地沟敷设的特殊需求,廊坊鑫大保温材料有限公司开发了用于地下管沟敷设的聚氨酯保温管道及附件,可以应用于输送长期运行温度140℃的高温热水。
