- Abstract:
- Using ANSYS to establish an axisymmetric model of the casing joint, focusing on the analysis of the sealing performance of a special threaded casing joint cylindrical/spherical sealing structure, respectively for the three working conditions (machine-tight, machine-tight+tension, machine-tight+internal) The distribution law of the contact pressure and equivalent stress of the sealing end is obtained, and the contact pressure and equivalent stress of the sealing end under different working conditions are compared and analyzed, revealing that the tensile load and the internal pressure of the casing have an impact on the structure. The impact of sealing performance. The results show that the contact pressure and equivalent stress of the cylindrical/spherical sealing structure meet the sealing requirements, which provides theoretical guidance for the further optimization design of special threaded casing joints.
