MEASUREMENT AND ANALYSIS OF HOT-STATE STRESS FOR MAIN STEAM PIPELINE OF UNIT NO. 10 IN NANCHANG POWER PLANT
摘要
采用高温应变片对南昌发电厂 1 0号机组主蒸汽管道工作状态下应力进行测量
目的是了解机组起动过程和管系支吊架调整前后主蒸汽管道实际应力的状况。实测结果分析表明
整个管系应力水平有明显降低
验证了支吊架调整的效果。测量为指导管系支吊架的调整和确定管系重点监督部位提供了科学依据。
Abstract
Measurement of the main steam pipeline stress for unit No. 10 in Nanchang Power Plant under operation condition has been carried out by lining high - temperature strain gauge
the aim of measurement being to make clear the actual stress situation of the said steam pipeline in the start - up course of the unit
as well as before and after adjustment of supports and hangers for the said pipeline. Analysis of the measured results shows that the stress level of entire pipeline system has been obviously lowered
verifying the effectiveness of adjusting the supports and hangers for the said pipeline
providing a scientific basis for guiding the adjustment of supports and hangers for the pipeline system
as well as for determining the key points for supervision on the pipeline system.
