Patent ID: 7086669

Claim:
A threaded connector for well tubulars, comprising: an axially and radially extending, internally threaded box member constructed from a radially expanded, plastically deformed first material, said first material having a first spring back characteristic, an axially and radially extending, externally threaded pin member threadedly engaged within said internally threaded box member and constructed from a radially expanded, plastically deformed second material, said second material having a second spring back characteristic that produces a smaller amount of radial contraction following plastic deformation than that produced by said first spring back characteristic of said first material whereby a compressive force is exerted between said pin member and box member resulting from a differential in said first and second spring back characteristics following radial plastic defamation of said pin and box members, and an axially and radially extending annular sealing component disposed, at least partially, coaxially with said pin and box, said sealing component having a third spring back characteristic for enhancing the sealing and/or mechanical engagement between said pin and box members following radial expansion of said pin and box and sealing component, said sealing component being disposed at least partially radially externally of said pin member and box member.
