摘要
分析了供热管道用普通波纹管补偿器直埋时遇到的有关问题,提出了整体解决方案。从加强自身防腐、防水密封、聚乙烯外护管的伸缩等方面采取措施,完成了直埋式波纹管补偿器的研发,在工程中应用效果良好。
Some problems encountered in direct installation of common bellows type expansion joints for heating pipeline are analyzed, and the total solution scheme is proposed. The development of directly buried bellows type expansion joints is achieved by taking measures in terms of strengthening their own anticorrosion, waterproof sealing, expansion and contraction of PE outer protection pipe and so on. A good application result in the engineering is obtained.
