关于压力容器开孔补强的几点说明

Opening Reinforcement of Pressure Vessel Points

论文分析说明了不同壳体上的开孔,开孔直接的确定准则,论述了常用开孔补强结构型式(即补强圈补强和整体补强)的补强效果:整体锻件补强优于厚壁管补强优于补强圈补强型,并给出了两种补强结构的适用范围。

This paper illustrates the determining norms of opening and hole diameter in different shell, discusses the reinforcement effect of the common opening reinforcement structure form （i.e. pad reinforcement and integral reinforcement） ： Integral reinforcement is better than that of thick wall pipe reinforcement which is superior to the reinforcement pad type, And gives the application scope of two kinds of reinforcing structure.
