汽轮机验收试验中ASME流量喷嘴的应用及应注意问题

Application of ASME Flow Nozzles and Related Problems to be Avoided in Turbine Acceptance Tests

针对国内部分新建项目采用由建设单位直接采购ASME流量喷嘴的状况,对ASME流量喷嘴与国家标准中标准喷嘴的差别进行了阐述,并对项目单位订购ASME流量喷嘴时应注意的问题、现场安装注意事项以及正常运行中ASME喷嘴的使用方法等进行了说明,为ASME流量喷嘴的现场正确应用提供了参考。

Currently some of the ASME Flow Nozzles are purchased by the owners in some new built projects. Description was given for the difference between the ASME Flow Nozzles and standard flow nozzles stipulated in the National Standard. The problems to be avoided in the ASME Flow Nozzle purchasing, the precautions to be taken during site erection, and the application method of ASME flow nozzle during normal operation were described in detail,in order to provide a reference for the correct application of the ASME Flow Nozzle on site.
