摘　　要：通过对主蒸汽管道的应力校核及应力优化计算,制定出了堵阀处优化处理方案。应力计算表明,该处理方案有效的优化了主蒸汽管道水平管段的应力水平,降低了堵阀出口处一次应力,为管道的安全运行提供了保障。Valve stress optimization and treatment scheme was made out by stress calculation on main steam pipeline. The result of stress calculation shows that, the scheme effective optimize stress of the horizontal main steam pipe, reduce the secondary stress at the outlet of valv. And the scheme pro- vides the safeguard for the safe operation of pipeline.
