高密度聚氨酯保温钢管厂家报价是多少?

  高密度聚氨酯泡沫能与各种材料进行牢固的粘合,因此作为直埋管的保温层几乎无需考虑防腐层与之粘合的问题。聚氨酯保温层的适应温度为+120℃-196℃,短时(十几小时)可达+190℃。如果用户需长期温度190度,J9九游会AG 可根据用户需要用高温料成型。保温管广泛用于液体、气体的输送管网,化工管道保温工程石油、化工、集中供、空调通风管道、市政工程等。高温预制直埋保温管是一种保温性能好,加安全可靠,工程造价低的直埋预制保温管。有效的解决了城镇集中供热中130℃-600℃高温输热用预制直埋保温管的保温、滑动润滑和管端的防水问题。高温预制直埋保温管不仅具有传统地沟和架空敷设管道难以比拟的技术、实用性能,而且还具有显著的社会效益和经济效益,也是供热节能的有力措施。高温预制直埋保温管采用直埋供热管道技术,标志着供热管道技术发展已经进入了新的起点。
