Abstract

Las uniones roscadas de tipo junta radial para tubos de acero aún pueden ser mejoradas en cuanto a asegurar la hermeticidad en términos de la rigidez del extremo macho. En forma específica, la superficie circunferencial externa de la nariz 8 del extremo macho 3 tiene una forma curva convexa hacia afuera, y la superficie de sello del extremo hembra 1 tiene una forma ahusada; y la superficie transversal del extremo macho 3 en el punto de sello sp que es una porción en la superficie circunferencial externa de la nariz 8 del extremo macho 3, estando la porción primero en contracto con la superficie de sello del extremo hembra 1 cuando se enrosca, es 35% o más de la superficie transversal de una porción de tubo original correspondiente a una porción sin procesar.Threaded joints of the radial joint type for steel pipes can still be improved in terms of ensuring tightness in terms of the stiffness of the male end. Specifically, the outer circumferential surface of the nose 8 of the male end 3 has a convex outwardly curved shape, and the seal surface of the female end 1 has a tapered shape; and the transverse surface of the male end 3 at the seal point sp which is a portion on the outer circumferential surface of the nose 8 of the male end 3, the portion being first contracted with the seal surface of the female end 1 when it is screwed , is 35% or more of the transverse surface of an original tube portion corresponding to an unprocessed portion.
