摘要: The invention concerns a premium tubular threaded joint comprising at least on element free-end abutting distal surface (7) of and seat the lip (5) spaced apart by given distance from threading. includes protuberance (13) which extends towards its free end beyond so that has both high radial stiffness low axial stiffness, thereby resulting in enhanced sealing properties under pressure and/or traction other advantages (real tightening torque accuracy, compression mechanical strength, impact barrier effect, engagement tolerance elements).
