直管线架空供热管网中补偿器的选用
Compensator selection for straight aerial heating pipeline
摘要：
通过DN500供热管线设计实例，介绍了不同类型波纹管补偿器在直管线架空供热管网中的应用，分析了其固定支架的受力，建议推广应用旁通直管压力平衡补偿器，以减少土建工程量，降低工程造价。

Abstract：
According to DN500 heating pipeline design example, presents the application of different types of bellow style expansion joints in the straight aerial and analyses the stress on the fixing trestle. Recommends using by-pass straight pressure balanced expansion joint, in order to reduce the volume of civil engineering and construction costs.
