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.
