| 摘 要： | 阐述了一种带金属/金属密封结构的双台肩气密封接头的具体结构,指出其上扣扭矩由主、副台肩面、密封锥面及螺纹4部分的摩擦扭矩构成,由于承载结构的变化,API推荐的上扣扭矩计算公式不再适用于这种气密封接头。本文运用圆锥过盈配合模型与应力应变模型建立了相应的扭矩计算公式,并通过有限元方法验证了该理论计算公式的可靠性。通过理论计算、有限元模拟与全尺寸上扣试验相结合的方法确定了该接头的最佳上扣扭矩,研究结果可为生产厂家及油田确定气密封接头最佳上扣扭矩范围提供参考。

| Abstract: | This paper describes the specific structure of a double shoulder connection with a metal to metal seal structure. The connection's make-up torque is consisted of four parts friction torque, which come from inner, outer shoulder surface, sealing surface and thread contact surface. Due to the change of bearing structure, API recommended torque calculation formula is no longer suitable for gas sealing joint. In this paper, a conical interference fit model and stress-strain model are used to establish the corresponding torque calculation formula, and the reliability of the theoretical calculation is verified by finite element method. The theoretical calculation, finite element simulation and full size make-up test are combined to determine the optimal torque of the joint, which provides reference for manufactures and fields to determine the optimum make-up torque range of gas sealing joint. |
