Abstract

Se proporciona una unión roscada (1), que es excelente en cuanto a la resistencia a la compresión y a la capacidad de sellado, en la que una porción roscada macho (4a) se pone en contacto con una porción roscada hembra (4b), tanto en una superficie del flanco punzante (9) como en una superficie del flanco de carga (10), mediante la unión roscada de una rosca cónica (4), mientras deja un espacio entre la porción roscada macho (4a) y la porción roscada hembra (4b), tanto en la superficie superior de la rosca (7) como en la superficie inferior de la rosca (8); la rosca cónica (4) tiene un ángulo del flanco de la superficie punzante (a) de 30º a 50º, un ángulo del flanco de la superficie de carga (b) de -10º o más y de menos de 0º, una conicidad de la rosca de 1/10 a 1/4, en donde la conicidad de la rosca representa en qué medida se cambia el diámetro por unidad de longitud, en una dirección de eje de caño o tubo, y un ángulo cónico de sellado (g) de una porción de sellado del miembro hembra (11b) de 3º a 10º.
