Abstract
Una conexión roscada para tubo de acero con rendimiento de sellado mejorado. Una conexión roscada (1) para tubo de acero incluye un vástago (10) y una caja (20). El diámetro externo de la caja (20) es menor que 108% del diámetro externo de un cuerpo de tubo de acero (30). El vástago (10) incluye un labio de vástago (12) que incluye una primera superficie de sello (11), una rosca macho (13) constituida por una rosca cónica de una sola etapa, y una segunda superficie de sello (14). La caja (20) incluye una primera superficie de sello (21), una rosca hembra (23) constituida por una rosca cónica de una sola etapa, y un labio de caja (22) que incluye una segunda superficie de sello (24). Cuando se ensamblan, las primeras superficies de sello (11, 21) están en contacto entre sí y las segundas superficies de sello (14, 24) están en contacto entre sí. Una porción de la rosca macho (13) localizada cerca al extremo del mismo próximo al labio de vástago (12) incluye una pluralidad de superficies de fondo de filete de rosca extendiéndose paralelas al eje del tubo (CL) y teniendo el mismo diámetro. Una porción de la rosca hembra (23) localizada cerca del extremo de la misma próximo al labio de caja (22) incluye una pluralidad de superficies de fondo de filete de rosca extendiéndose paralelas al eje del tubo (CL) y teniendo el mismo diámetro.A threaded connection for steel pipe with improved sealing performance. A threaded connection (1) for steel tube includes a rod (10) and a box (20). The outer diameter of the box (20) is less than 108% of the outer diameter of a steel tube body (30). The rod (10) includes a rod lip (12) that includes a first seal surface (11), a male thread (13) constituted by a single stage conical thread, and a second seal surface (14). The box (20) includes a first seal surface (21), a female thread (23) constituted by a single stage conical thread, and a box lip (22) that includes a second seal surface (24). When assembled, the first seal surfaces (11, 21) are in contact with each other and the second seal surfaces (14, 24) are in contact with each other. A portion of the male thread (13) located near the end thereof close to the rod lip (12) includes a plurality of thread fillet bottom surfaces extending parallel to the axis of the tube (CL) and having the same diameter. A portion of the female thread (23) located near the end thereof close to the box lip (22) includes a plurality of thread fillet bottom surfaces extending parallel to the axis of the tube (CL) and having the same diameter.
