Finite Element Simulations of Mechanical Properties of Solid Expandable Tubular Threaded Joint


Article Preview

In this paper, threaded joint dedicated for the solid expandable tubular is taken as the basic structure and specific parameters for the threaded joint is set. 16Mn improved material is selected as the material, and MSC/Marc software is adopted to conduct finite element analog study on technical performance of the threaded joint and to analyze the distribution and strain condition of microstress and macrostress for the thread after make-up as well as the tensile strength and sealing property for the joint after make-up. Multiple important data concerning the designed expandable tubular threaded joint have been obtained through the study. It is convinced that the solid expandable tubular threaded joint shall adopt be a flush one with both internal and external walls parallel and level with the tubular body, and the type of thread shall take a shape of reversed hook. Besides, the expandable tubular threaded joint shall adopt the sealing structure with the rubber seal as the main sealing type and metallic seal auxiliary.
