压力容器不设置检查孔时的“计算厚度”

Calculated Thickness of Pressure Vessels without Checking Hole

在压力容器中不设置检查孔所需标注的“计算厚度”,并非是GB150-89中的“计算厚度”,应考虑参与补强所需厚度这个因素。本文以工程中的一个实例分析,以期引起设计者的重视,以确保容器使用的安全。

When the pressure vessel is designed without checking hole, the calculated thickness of the pressure vessel written on the drawing, sometimes, is not the same illustrated in GB150-89. In this case, the part of the thickness used to reinforce the opening should be accounted for. In the paper, one practical example was demonstrated to explain how to deal with the situation.
