Description

一种聚乙烯外护保温管
技术领域
本实用新型涉及建材领域，尤其涉及一种聚乙烯外护保温管。
背景技术
目前，聚乙烯外护保温管广泛应用于城市集中供热、暖室、石油港口、化工等行业的保温工程，市面上的聚乙烯外护保温管会出现保温性能不好、不具有防水和耐腐蚀的能力、使用寿命不长。
实用新型内容
本实用新型的目的是提供一种聚乙烯外护保温管，它能直接埋入地下或水中，具有优异的防腐性能和保温性能，长期运行可节约大量能源，施工简便。
为了解决背景技术所存在的问题，本实用新型是采用以下技术方案：它是由聚乙烯外护管1、聚氨酯保护层2、芯管3组成；聚乙烯外护管1内设置有聚氨酯保护层2，芯管3同心设置在聚氨酯保护层2内。
所述的聚氨酯保护层2的材料为密度大于70kg/m3的硬质聚氨酯泡沫，泡沫充分填满芯管3与聚乙烯外护管1之间的间隙，具有一定的粘度，是聚乙烯外护管1、聚氨酯保护层2和芯管3三者形成一个牢固的整体。
本实用新型能直接埋入地下或水中，具有优异的防腐性能和保温性能，长期运行可节约大量能源，施工简便。
附图说明：
图1是本实用新型的结构示意图。
具体实施方式：
参照图1，本具体实施方式采用以下技术方案：它是由聚乙烯外护管1、聚氨酯保护层2、芯管3组成；聚乙烯外护管1内设置有聚氨酯保护层2，芯管3同心设置在聚氨酯保护层2内。
所述的聚氨酯保护层2的材料为密度大于70kg/m3的硬质聚氨酯泡沫，泡沫充分填满芯管3与聚乙烯外护管1之间的间隙，具有一定的粘度，是聚乙烯外护管1、聚氨酯保护层2和芯管3三者形成一个牢固的整体。
本具体实施方式能直接埋入地下或水中，具有优异的防腐性能和保温性能，长期运行可节约大量能源，施工简便。
