    摘要: A threaded joint for steel pipes comprising a pin (1) and a box (2). The pin has a male thread (11) and a lip (12) which comprises (i) a sealing surface (13) and (ii) a nose portion (16) provided with a shoulder surface. The box has a female thread (21), a sealing surface (23) and a shoulder surface. The shoulder surface of the pin comprises two distinct adjacent surfaces, main shoulder (14) in the inner side and sub shoulder (15) in the outer side. Correspondingly, the shoulder surface of the box comprises two distinct adjacent surfaces, main shoulder (24) in the inner side and sub shoulder (25) in the outer side. The main shoulder surfaces of the pin and box are disposed such as to prevent a radially inward deformation of the lip end, and the sub shoulder surfaces of pin and box are disposed such as to limit a radially outward deformation of the lip end. The main shoulder of the pin has a greater radial dimension than said sub shoulder of the pin, and at least the main shoulder surface of the pin is in axial abutment with at least the corresponding main shoulder surface of the box.

    摘要: A threaded tubular connection that is leak-proof for internal and external successive pressure loads including a male element and a female element. At least one of the male or female elements includes a lip between the threading and the free end of the element. The lip includes a first zone with a peripheral surface turned towards the other element on which a first metallic sealing surface is disposed that can be radially interference fitted against a corresponding second metallic sealing surface disposed on the other element. The lip includes a second zone located axially between the first zone and the corresponding threading. The radial stiffness of the second zone is less than that of the first zone and that of a third zone adjacent to the second zone in the direction of the threading, and the second zone can be radially deformed by a pressure exerted thereon.
