Abstract

Se proporciona una conexión roscada para tubo de acero que puede proporcionar una cierta resistencia al esfuerzo de torsión y reducir los costos de fabricación. Una conexión roscada (1) para tubo de acero incluye un vástago (10) que incluye una porción de rosca macho (11) en una periferia exterior, y una caja (20) que incluye, en una periferia interior, una porción de rosca hembra (21) y adaptada para enroscarse en el vástago (10). La porción de rosca macho (11) incluye una rosca macho principal (111) y una rosca macho auxiliar (112). La rosca macho principal (111) está constituida por una rosca trapezoidal que tiene un ancho de cresta de rosca constante y un ancho de raíz de rosca constante. La rosca macho auxiliar (112) está ubicada en una raíz de rosca de la rosca macho principal (111) y tiene un ancho de cresta de rosca y una altura de cresta de rosca que son más pequeñas que las de la rosca macho principal (111). En una sección transversal que contiene un eje de tubo del vástago (10), el ángulo de flanco del flanco de ataque (111c) de la rosca macho principal (111) y el ángulo de flanco del flanco de carga (112d) de la rosca macho auxiliar (112) en ubicaciones adyacentes son mayores de 0 grados.
