化工设备基于目标载荷的螺栓扭矩计算

Calculation of Bolt Torque for Chemical Vessels which based on Target Stress

螺栓法兰接头的螺栓扭矩的计算选用是工程设计人员的常见问题之一。本文针对如果基于紧密度等级选用目标载荷,并将目标载荷换算成螺栓扭矩及如何测定螺栓的润滑状态等做出分析与讨论。并给出了常用的螺栓的相关参数,方便实际应用中选用。

The calculation and selection of bolt torque for bolted flange connections are the most difficult problem which faced by the engineering.in this paper,discuss about the target stress which is based on tightness grade,and how to conversion the target stress into the bolt torque,also discussion how to testing the friction condition of bolt etc.Two suggested data list of standard bolt are attached for choose in daily working.
