Abstract

Se proporciona una junta atornillada para tubo que mejora la propiedad de sellado, propiedad de resistencia a la compresión y propiedad de resistencia a la pérdida por rozamiento. La junta atornillada para tubo tiene un miembro de perno 3 del cual un diámetro externo de una porción de tubo en bruto se fija a 168.3mm o menos. Una superficie periférica exterior de una porción de punta del miembro de perno 3 se forma en una curva convexa que se proyecta hacia afuera como se ve en la sección transversal tomada a lo largo de una dirección axial del miembro de perno. La curva convexa se forma en una forma curvada donde una curva R compuesta se forma al poner en contacto secuencialmente una pluralidad de arcos convexos hacia afuera que tienen diferentes radios de curvatura R entre sí en una línea de generación de una porción cilíndrica dispuesta adyacente a una porción roscada macho. Un radio de curvatura R del arco se aumenta conforme el arco se aleja de la porción roscada macho, y una tangente del arco en un punto de conexión concuerda con una tangente del arco que es una contraparte de conexión. La superficie periférica interior de un miembro de caja 1 está formada en una superficie cónica que interfiere con la superficie periférica exterior de la porción de punta del miembro de perno en el momento de unión con el miembro de perno, y una longitud de la porción de punta del miembro de perno se fija a 5 mm o más y menos de 20 mm.
