THREADED CONNECTION, CONTAINING A LESS THEME ONE THREAD THREAD ELEMENT WITH A FRONT END FOR METAL PIPE

摘要

A threaded tubular joint (1) which comprises an inner threaded portion (2) at the end of the first tubular component and an outer threaded portion (3) at the end of the second tubular component; internal threaded part (2) contains internal thread (4), at least one internal sealing surface (12) on its internal peripheral surface, at least one internal axial bearing surface (8); the external threaded part (3) contains an external thread (5), at least one external sealing surface (13) on its external peripheral surface, at least one external axial bearing surface (7) and a flange (9) made between the sealing surface (13a) and an axial bearing surface (7) located at the free end of the specified threaded part, which is separated from the thread; wherein the external thread (5) is screwed into the internal thread (4), so that the external axial bearing surface (7) is in contact with the internal axial bearing surface (8); at least one external sealing surface is in contact with at least one internal sealing surface; the outer part of the edge (9) between the sealing surface and the axial bearing surface is radially spaced from the corresponding surface of the other threaded part; part of the edge (9) and the corresponding surface of the other threaded part with the internal space of the connection.
