Abstract
Una union roscada para tubos de acero que comprende un enchufe 1 con rosca macho ahusada 11, una superficie de sellado ahusada 13, y una cara de hombro extremo 14, y una caja 2 con correspondiente rosca hembra ahusada 21, superficie de sellado ahusada 23, y cara de hombro 24, la cual es capaz de ser apretada fácilmente y tiene hermeticidad mejorada a los gases por las superficies de sellado, está dispuesta de manera que el enchufe y la caja tienen sendas zonas libres de contacto B donde las superficies periféricas del enchufe y de la caja no hacen contacto entre sí entre las superficies de sellado 13, 23 y las superficies de hombro 14 y 24. Al menos la porcion adyacente al extremo del enchufe de la zona libre de contacto del enchufe es una porcion de superficie ahusada 18 con sustancialmente el mismo ángulo de inclinacion que la superficie de sellado ahusada 13, siendo la zona libre de contacto de la caja una superficie sustancialmente cilíndrica.A threaded joint for steel tubes comprising a plug 1 with tapered male thread 11, a tapered sealing surface 13, and an end shoulder face 14, and a box 2 with corresponding tapered female thread 21, tapered sealing surface 23, and shoulder face 24, which is capable of being easily tightened and has improved gas tightness by the sealing surfaces, is arranged so that the plug and the box have free contact areas B where the peripheral surfaces of the plug and of the case they do not make contact with each other between the sealing surfaces 13, 23 and the shoulder surfaces 14 and 24. At least the portion adjacent to the plug end of the contact-free area of the plug is a tapered surface portion 18 with substantially the same angle of inclination as the tapered sealing surface 13, the contact-free area of the housing being a substantially cylindrical surface.
