Product Details
 直埋热力保温管,热力管道保温管
公司秉承“同等价格看质量,同等质量看价格;为客户之所需,做客户之所想;诚信经营,以人为本”的理念,坚持做好产品,坚持做高品质、低价位的产品,坚持做客户满意的产品。欢迎各位咨询、洽谈、合作!选我们,您放心!
 
聚氨酯保温材料是目前国际上性能最好的保温材料。硬质聚氨酯具有质量轻、导热系数低、耐热性好、耐老化、容易与其它基材黏结、燃烧不产生熔滴等优异性能,聚氨酯保温板在许多国家广泛用于建筑物的屋顶、墙体、天花板、地板、门窗等作为保温隔热材料。预制聚氨酯保温管则用于石油、化工、城市热网、市镇建设等工程的保温防腐工作中。 
 
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、外套管及保温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家已成为一项比较成熟的先进技术。近十几年,我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。十几年来的实践成果充分证明了聚氨酯保温直埋管建设方式与传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,以及钢管和外套管之间的硬质聚氨酯泡沫保温层紧密结合而成.
 
 
 
专业生产聚氨酯保温管、直埋保温管、预制保温管、环保管道保温管、冷热水保温管、节能型热力保温管、钢套钢保温管、复合保温管、岩棉保温管瓦、硅酸铝保温管瓦等几十种保温材料。高品质低价格、供货及时、优秀的服务团队全天候为广大客户服务。欢迎拨打热线电话咨询。
 
预制直埋保温管结构由里到外可分为三层:
 
第一层为输送介质的工作芯管
芯管一般材质为无缝管(GB8163-87)螺旋焊管(GB9711-88;SY/T5038-92)和直缝焊管(GB3092-93)及镀锌钢管和PPR等材质;可根据用户不同要求选择,其芯管管径为【 φ22、25、32、38、45、57、76、89、108、133、159、219、273、325、377、426、478、529、630、720、820、920、1220】
第二层为保温层材料为聚氨酯泡沫塑料或复合保温材料,【其保温层厚度为30-150mm】
第三层为外护层为高密度聚乙烯夹克管、玻璃钢缠绕管及防腐钢管。
