Abstract

conexão roscada para tubo de aço. um objetivo da presente divulgação é fornecer uma conexão roscada para tubo de aço com grande diâmetro que pode apresentar alta resistência de torque e alta capacidade de vedação e, ao mesmo tempo, fornecer uma resistência ao cisalhamento que se adapte ao tamanho do tubo de aço a ser conectado. a conexão roscada 1 para tubo de aço inclui um pino tubular 10 fornecido em uma ponta de um tubo de aço 2 com grande diâmetro e uma caixa tubular 20 adaptada para ser feita no pino 10 quando o pino 10 é aparafusado. o pino 10 inclui uma forma de rosca macho 11 feita com uma rosca cônica. a caixa 20 inclui uma forma de rosca fêmea 21 feita com uma rosca cônica. cada uma das formas de rosca 11 e 21 é uma rosca em cunha e tem uma seção transversal em forma articulada. a forma de rosca macho 11 é projetada para satisfazer as seguintes expressões (1) e (2) de modo que a largura da rosca em uma região de extremidade da forma de rosca macho mais próxima da ponta seja definida para um tamanho correspondente ao tamanho do corpo de tubo do tubo de aço 2.
