聚氨酯保温管施工要点

发布日期:2019-03-04 作者: 点击:

聚氨酯保温直埋管从节约能源、降低造价、缩短施工周期、保护环境多方面来看,不仅具有传统地沟和架空敷设管道难以比拟的技术和实用性能,同时具有显著的社会效益和经济效益。由于直埋供热技术在我国起步较晚,从工程实践中出现的质量问题来看,聚氨酯保温管施工要点在设计和施工中应该被重视起来。

1.有补偿直埋敷设方式,是通过管线自然补偿和补偿器(如方形和波纹管补偿器)来解决管道热伸长量的,从而使热应力为最小;无补偿直埋敷设,简单地说就是管道在受热时没有任何补偿措施,而是靠管材本身强度来吸收热应力。1531792588410426.jpg
