                       产 品 说 明
                    聚氨酯直埋保温管
                      
                       
                    聚氨酯直埋保温管又称“管中管”其有“两步法”构成,是由高密度聚乙烯外保护层、聚氨酯硬质泡沫塑管和钢管组成。 保温层材料60kg/m3至

                    80kg/m3的硬质聚氨酯泡沫,充分添满钢管与套管之间的间隙,并具有一定的粘接强度,使钢管、外套管?#27688;?#28201;层三者之间形成一个牢固的整体。 聚氨

                    酯直埋保温管泡沫具有良好的机械性能和绝热性能,通常情况下可耐温120℃通过改性或与其它隔热材料组合可耐温180℃。 

                      聚氨酯保温直埋管在国外一些发达国?#20057;?#25104;为一项比较成熟的先进技术。近十?#25913;輳?#25105;国供热工程技术人员通过消化、吸收这项先进技术,正推动

                    着国内管网建设技术向更高的层次发展。十?#25913;?#26469;的实践成果充分证明了聚氨酯保温直埋管建设方?#25509;?#20256;统的地沟及架空建设相比,具有诸多优点。直

                    埋式保温管是由输送介质的钢管,高密度聚乙烯外套管,以?#26696;?#31649;和外套管之间的硬质聚氨酯泡沫保温层紧密结合而成。




                       聚氨酯直埋保温管有十分突出的优点:

                       1、聚氨酯直埋保温管保温性能好,热损失仅为传统管材的25%,长期运行?#23665;?#32422;大量能源,显著降低能源成本。   

                       2、具有很强的防水和耐腐蚀能力,不需附设管沟,可直接埋入地下或水中,施工简便迅速,综合造价低。

                       3、在低温条件下也具有良好的耐腐蚀和耐冲击性,可直接埋入地下冻土。

                       4、使用寿命可达30-50年,正确的安装和使用可使管网维修费用极低。

                       5、可设置报警系?#24120;?#33258;动检测管网渗漏?#25910;希?#20934;?#20998;?#31034;?#25910;?#20301;置并自动报警。

                       6、使用寿命可达30-50年。管径:DN15--DN600 厚度:15--50mm 用途:集中供热管道、制冷管道、工业管道等。

                       7、含氧指数:≥27 密度:40--70kg/立方m 憎水率:0.03kg/立方cm 导热系数:0.022kcal/m.h.℃
