Abstract

Conexión roscada que proporciona un alto desempeño de sellado. La conexión roscada (10) incluye un vástago (1) y una caja (2). Una rosca macho interna (13) del vástago (1) incluye una porción paralela (131). La porción paralela (131) se ubica en una porción extrema de la rosca macho interna (13) adyacente a la superficie interna de sellado de vástago (11), y posee raíces de filetes de rosca paralelos al eje del tubo. Una rosca hembra interna (23) de la caja (2) incluye una porción cónica (231). La altura de filete de rosca en la porción cónica (231) es mayor que en la porción paralela (131). Da<Db se satisface, en donde Da es la diferencia en diámetro entre crestas de filetes de rosca adyacentes (231a) en la porción cónica (231) en una sección transversal longitudinal del vástago (1) y de la caja (2) como se encuentra cuando la conexión no se ha acoplado, y Db es la diferencia entre el diámetro de la raíz de filete de rosca (131a) en la porción paralela (13) y el diámetro máximo de la superficie interna de sellado de vástago (11).
