直埋聚氨酯保温管的的优势体现

发布日期:2018-07-19 作者: 点击:

钢套钢埋地式蒸汽保温管 直埋保温管道也叫预制保温管道分两种:是塑套钢保温管(高密度聚乙烯直埋保温管道)与钢套钢保温管(高温蒸汽保温管)  预制直埋蒸汽保温管产品,可用于输送介质温度不大于350℃的蒸汽、导热油或其他介质。产品执行《城镇供热预制直埋蒸汽保温管技术条件》(CJ/T200- )、《城镇供热管网工程施工及验收规范》(CJ28-2004)等标准。   钢套钢复合保温钢管是地下直埋管道中的一种,采用没有混凝土结构的情况下也可以进行地下直埋的方式,即工作钢管的热膨胀在外管内进行,从而降低了材料成本,缩短了施工日期,并保障了供热管道的安全性,可以在不同温度环境下更安全的广泛应用,尤其适用于高温蒸汽管道项目。使用温度可达150℃-450℃。
