承压设备用螺纹副旋合长度确定方法探讨

Discussion on Determination Method of Screw Length of Thread Pair for Pressure Equipment

目前我国专业资料;给出了标准的螺柱螺母螺纹连接的保证载荷值及最小拉力载荷值,非标准的螺纹副连接的承载能力没有明确给出计算方法,本案就此问题做一些分析和探讨,给出工程计算建议,仅供业者参考。

At present,China’s professional data;gives the guaranteed load value and the minimum tensile load value of the standard stud nut threaded connection,but there is no clear calculation method for the bearing capacity of the non-standard screw pair connection.This case makes some analysis and Discussion on this problem,and gives the engineering calculation suggestions,which is only for the reference of the industry.
