摘要: 为了解决管道压降计算的准确性问题，基于对前苏联、德国、美国的管道压降算法进行比对分析，结合火电厂主要蒸汽管道的特点和性能试验数据，提出了一种优化和精确的蒸汽管道压降的算法。新的算法消除了先前算法由于试验条件、理论计算、制造工艺等的不同对于结果的偏差，对主要蒸汽管道的系统、布置的优化提供了更为有效的途径。

Abstract: In order to solve the problem of pipeline pressure drop calculation accuracy, in this paper, based on comparison to the analysis algorithms of pipeline pressure drop in Soviet Union, Germany and U. S., combined with characteristics and performance of major steam piping in thermal power plant, an optimized and accurate algorithm of steam pipe pressure drop was proposed. The new algorithm eliminated deviation of the results in previous algorithm because of the difference of test conditions, theoretical calculations, manufacturing processes. New pipeline pressure drop algorithm for thermal power plant major steam piping provides a more effective way to optimize of layout and process of major pipeline.
