直管压力平衡型膨胀节在管廊设计中的应用

摘要

Regarding the application of expansion joint of balanced pressure straight pipe that used in piping rack, with mainly focusing on design and working principles of expansion joint, it is concluded that expansion joint could absorb secondary force that generated by piping and reduce fixed thrust as well as diminish the resistance of the piping racks by the analysis on practi-cal samples and calculation on results.%针对直管压力平衡性型膨胀节在管廊中的应用，重点介绍了膨胀节的设计和工作原理，通过在工程中的应用实例分析、计算得到结果，得出膨胀节能吸收管线产生的二次应力，降低固定点的推力，减小管道的阻力的结论。
