Abstract

Una unión roscada (1) está constituida por un Pin (13) y un Box (12). El Pin (13) incluye una superficie de hombro (59), una superficie de sellado (56), y una porción roscada macho (51). El Box (12) incluye una superficie de hombro (24), una superficie de sellado (22), y una porción roscada hembra (21). La porción roscada macho (51) y la porción roscada hembra (21) son ambas porciones cónicas que incluyen roscas (57, 31) y tienen un perfil trapezoidal. La porción roscada macho (51) tiene un ancho de las roscas (57) que disminuye gradualmente a lo largo de la espiral de la rosca y un ancho de surcos (62) que aumenta gradualmente a lo largo de la espiral de la rosca. La porción roscada hembra (21) tiene un ancho de surcos (42) que disminuye gradualmente a lo largo de la espiral de la rosca y un ancho de las roscas (31) que aumenta gradualmente a lo largo de la espiral de la rosca. Con ello, es posible inhibir el cizallamiento durante en enrosque y al mismo tiempo mantener una alta capacidad de sellado, como así también lograr una facilidad de fabricación.A threaded joint (1) consists of a Pin (13) and a Box (12). The Pin (13) includes a shoulder surface (59), a sealing surface (56), and a male threaded portion (51). The Box (12) includes a shoulder surface (24), a sealing surface (22), and a female threaded portion (21). The male threaded portion (51) and the female threaded portion (21) are both conical portions that include threads (57, 31) and have a trapezoidal profile. The male threaded portion (51) has a width of the threads (57) that gradually decreases along the spiral of the thread and a width of grooves (62) that gradually increases along the spiral of the thread. The female threaded portion (21) has a groove width (42) that gradually decreases along the spiral of the thread and a width of the threads (31) that gradually increases along the spiral of the thread. With this, it is possible to inhibit shearing during screwing and at the same time maintain a high sealing capacity, as well as achieve ease of manufacturing.
