Premium threaded tubular joint comprising at least a threaded element with end lip

摘要: A premium threaded tubular connection including, on at least one element, a distal abutment surface the free end of and lip sealing given distance from threading. The includes an appendix that extends towards its beyond so has both high radial stiffness low axial stiffness. This results in enhanced performance as regards seal under pressure and/or tension, other advantages precision real makeup torque, mechanical strength compression, shock barrier effect, tolerance engaging elements.
