Magnitude of Interference Design of Premium Thread Connection
To design a premium connection of low grade and thin wall thickness tubing with lower makeup torque,this paper first analyzes the connections with various combination of machining errors,finds the linear correlation between the thread magnitude of interference and shoulder torque with FEA Monte Carlo simulation and provides the initial thread magnitude of interference of the designed premium connec-tion.And then,we validate and determine the thread magnitude of interference and makeup torque with full scale test.The results show that the distribution of the shoulder torque with different thread magnitude of interference can be obtained from FEA method and the biggest shoulder torque is consistent with the torque from the full scale makeup test.
