Study of the Load Distribution in Threaded Connection of Casings

The intention in this work is to identify the bearing capacity reserve of trapezoidal threaded connection of casings. A computer-based modelling of threaded connection screwing, with various values of preload and applied tensile force, was made. This modelling is performed using the method of finite elements, that allows to demonstrate the stress-strain state of the solid body when affected by external factors. The conducted experiments have shown that radial component of preload in the connection causes an increase in the diameter of a coupling and reduction in its longitudinal size with a simultaneous decrease in the coupling thread pitch. At the same time, a decrease in thread diameter of pipe nipple occurs, and its length and thread pitch increase. Although there are minor changes in coupling and pipe nipple thread pitches, they cause an abrupt redistribution of the components of longitudinal load, absorbed by the thread turns: the greater value preload has, the more uneven turn-wise distribution of load is.
