Abstract

Conexión roscada para tubo de acero con un desempeño de sellado mejorado contra la presión interna, caracterizado porque no se disminuye el desempeño de sellado contra la presión externa. Una conexión roscada para tubo de acero ( 1) incluye un vástago ( 10) y una caja ( 20). El vástago ( 10) incluye un labio de vástago ( 11) con una superficie de sello interior del vástago ( 11a) y una nariz ( lib) y una rosca macho ( 13). Cada una de la rosca macho ( 13) y de la rosca hembra ( 23) en la caja ( 20), se encuentra constituida por una rosca cónica de cola de milano. Cuando la conexión ha sido ensamblada, el flanco de ataque de la rosca macho ( 13) y el flanco de ataque de la rosca hembra ( 23) se enfrentan entre sí con una holgura proporcionada entre ellos. La distancia D entre la rosca macho ( 13) y la superficie de sello interior del vástago ( 11a) es 1. 5 veces el paso de rosca de la rosca macho ( 13) o mayor. La longitud L de la nariz ( lib) es mayor que el paso de rosca de la rosca macho ( 13). La diferencia entre la distancia D y la longitud L es igual o menor que el paso de rosca de la rosca macho ( 13).
