浅析核电厂管道经济流速 The Analysis of Economic Velocity of Pipe in Nuclear Power Plant

为进一步提高核电厂管道系统的经济性，对国、内外管道经济流速进行研究分析，管道经济流速主要取决于能源价格和钢材价格；同时，国外管道推荐经济流速已呈现出向低流速发展的趋势。本文利用国外推荐的GENERAUX方程对影响管道经济流速相关因素进行了分析。结果表明：随着管道直径的增加，管道经济流速呈现出降低趋势；当单位能耗每增加1美元时，管道经济流速降低约4.5%；单位材料费用每增加1美元，管道经济流速约上升1.1%。 To make nuclear power plant more economical, the article studies the economic velocity at home and abroad, and the study finds that the pipe economic velocity is mainly based on energy price and steel price, and the recommended economic velocity is tending to decline overseas. Through the factor analysis with the help of GENERAUX equation, the results show that the pipe economic velocity will decrease along with the increase of pipe diameter; the pipe economic velocity will drop about 4.5% with unit cost of energy increased by 1$; And the pipe economic velocity will rise about 1.1% with unit cost of material increased by 1$.
