产品名称: 聚氨酯直埋发泡保温管的报价
规格型号:DN219
保温厚度:按国标执行
使用范围/用处:集中供热管道、制冷管道、工业管道等
胜明聚氨酯保温钢管运用功率十分高,也促进如今聚氨酯保温钢管大面积遍及,也真真切切的帮助聚氨酯保温钢管运用资料削减了许多工业损耗,节省环保,带着大家都因而获益,聚氨酯保温钢管契合国家倡导,也让大家对聚氨酯保温钢管的认可度很高导热系数公式为λ=0.3kcalm·h·oC,依据我公司的钢管资料具体的核算出了聚氨酯保温钢管的保温作用进步4~9倍,和别的一般的管道保温资料比较保温作用高的多。另一方面聚氨酯保温钢管吸水率很低,由于导热系数和吸水率低的原因,再加上保温层和外面防水功能好的高密度聚乙烯或玻璃钢维护壳,改变了传统地沟敷设供热管道“穿湿棉袄”的状况,大大削减了供热管道的全体热损耗。这么从两方面使得钢管热损耗大大削减
聚氨酯直埋保温管一种是由运送介质的钢管、防腐外套钢管以及钢管与外套钢管之间填充的超细玻璃棉组合而成,也可选用石墨、硅钙管壳及填充聚氨酯泡沫复合而成。
聚氨酯直埋保温管由内钢管、外维护钢管和保温层组成。
钢管经喷砂涂两层防锈漆。保温层由高温纤维毡、超稍微孔硅酸钙保温WA和聚氨酯泡沫塑料组成。
外套钢管作喷砂处理后环绕六层玻璃纤维和树脂防腐层。
聚氨酯直埋保温管具有以下特色:尺度完全的管材及配件,满足各种工程需求;该管材有很好的耐性、气密性和抗老化功能,适于压力(虹吸)流雨水体系运用;管材有较强的抗冲击性,耐热耐磨及耐酸碱侵蚀性。
