对压力容器承压壳体内壁攻丝深度的探讨

Discussion on Tapping Depth of Inner Wall of Pressure Vessel Shell

在现有的设计标准中,还没有对承压壳体内壁的攻丝深度作出规定。通过分析,应用材料断裂力学原理,依据承压壳体内壁的攻丝深度进行了强度计算,并给出设计承压壳休攻丝的允许深度,可为设计承压壳体时提供参考。

In the existing design standards,the tapping depth of the inner wall of the pressure vessel shell has not been stipulated.Through analysis and application of material fracture mechanics principle,strength calculation is carried out according to tapping depth of inner wall of pressure-bearing shell.Permissible tapping depth of pressure-bearing shell is given,which can provide reference for design of pressure-bearing shell.
