AP1000核电主管道弯曲件尺寸检测方法的研究

Method Study on the Measurement of the Dimensions of the Bent Main Pipe for AP1000 Nuclear Power Plant

在系统总结AP1000核电主管道的检测标准和技术要求基础上,研究了主管道尺寸的测量方法。推导出测量主管道各个关键尺寸、角度的计算公式,形成了一种系统化、参数化的主管道测量基础方案,为研究和控制主管道弯曲工艺提供了一些关键参考条件和技术支撑,也为主管道进一步加工、验收及安装提供了重要的条件和保证。

In this paper,the inspection specification and technical requirement of the main pipe are systematic summarized,the measurement method of the dimensions of the bent main pipe is studied.The measurement and calculation formula for all the key dimensions and angles are deducted.A systematic and formulated basic solution for measuring the main pipe is found.It not only provides the key reference condition and technical support to study and to control the bending process,but also provides the important condition and assurance for the main pipe to be further machined,inspected,accepted and assembled eligibly.
