Analysis of Influence to the Connect and Seal Ability of Tubing Connection of Inner Pressures

Abstract:

To know the stress distribution of tubing connections with varied inner pressures for further understanding of the influence of pressures to the connection and seal ability, finite element model of API tubing connection was established and the Von Mises stresses and contact pressures of tubing connection was analyze by full make-up torque and varied inner pressures with nonlinear finite element method. It was found that the contact pressures and stresses on engagement threads may be increased with limited inner pressure. Meanwhile, stresses of engagement threads on both ends increased more sharply than others. And plastic deformation even breakage of engagement threads may occur if the inner pressure exceeds 70MPa
