Calculation Method of Make-up Torque on Premium Threaded Casing Connection
摘要
Abstract
The composition of the make-up torque on the premium threaded casing connection was studied,and a calculation method based on the thick-wall cylinder theory was established.The radial interference of the screw thread was determined and the effect of the friction coefficient of screw thread on the torque of the upper button was analyzed.The results show that in the case of a certain interference fit,the greater the friction coefficient of the screw thread fat,the greater the ratio of radial interference torque to the total one,and the ratio gradually tends to a certain value.In the process of premium threaded casing connection,the tolerance and fit should be optimized,priority given to ensure the machining accuracy and surface roughness of the sealing structure,and attention payed to the choice of thread compound.By using the calculation method given in this paper,the make-up torque on premium threaded casing connection can be estimated better.关键词
