调查和评估了国有管线锥形螺纹管(NPT)在一个特殊类型的往复式压缩机单元中的应用性能和预期寿命。研究致力于评估作用于螺纹连接的激发力和产生的应力的等级。这些力和应力取决于一个系统的机械模型上应用的现场振动测量结果。应用有限元分析模型计算了轴向和周向载荷下螺纹的应力集中系数。
Investigated and evaluated the performance and life expectancy of state-of-the-art conical threaded pipe (NPT) applications in a particular type of reciprocating compressor unit. The research is devoted to assessing the level of stress and stress that act on a threaded connection. These forces and stresses depend on the field vibration measurements applied to a systematic mechanical model. The finite element analysis model was used to calculate the stress concentration factor of the thread under axial and circumferential loads.
