Abstract

La conexión roscada descrita para tubos de acero incluye un perno (10) que incluye una parte roscada macho cónica (11) y una parte de hombro y una caja que incluye una parte roscada hembra cónica y una parte de hombro. En un estado ensamblado en el que las partes de hombro están en contacto entre sí, las raíces (13) de la parte roscada macho (11) están en contacto con las crestas de la parte roscada hembra mientras interfieren con las crestas y se proporcionan espacios libres entre las crestas (12) de la parte roscada macho (11) y raíces de la parte roscada hembra. En una sección longitudinal que incluye un eje de tubo (CL) de la conexión roscada, las crestas (12) de la parte roscada macho (11) se forman en una curva convexa que es tangente a las dos primeras porciones de esquina (12a) que se forman en un arco que conecta las crestas (12) y los flancos de carga (15) y las segundas porciones de esquina (12b) que se forman en un arco que conecta las crestas (12) y los flancos de ataque (14). Se proporciona un recubrimiento de lubricante sólido (30) sobre la superficie de la parte roscada macho (11).
