Abstract
"CONEXãO PARA PINO E CAIXA FILETADOS, CAIXA DE ENCOSTO PARA A MESMA, CONEXãO DE ENCOSTO DE PINO E CAIXA, E, MéTODO PARA MODIFICAR UMA CONEXãO DE JUNTA DE FERRAMENTA DE ENCOSTO CONVENCIONAL". Uma conexão de tubos com pino (11) e caixa (12) filetados (macho e fêmea), que tem encostos de constituição (15, 16) que se contatam quando os filetes do pino e caixa são completamente engatados. Quando do engatamento inicial dos encostos, flancos de carga (36, 31) dos filetes de pino e caixa mais afastados dos encostos de constituição, engatam um ao outro e começam a se separar progressivamente um do outro, por uma quantidade crescente, ao longo do comprimento dos filetes engatados, em uma direção a partir da extremidade do pino até um ponto aferidor da conexão. Quando da aplicação do torque de constituição, a separação entre os flancos de carga distribui as forças de torque entre os encostos de constituição ao longo do comprimento dos filetes engatados para impedir concentração de forças de tensão próximo à base do filete do pino. A separação progressiva dos flancos de carga é conseguida mudando progressivamente o passo do filete do flanco de carga do pino e/ou da caixa, para variar a largura do filete. A separação de flancos de carga é conseguida sem modificações do passo do flanco de golpe. O passo do flanco de carga é reduzido de maneira uniforme ao longo do comprimento do filete para conseguir, de maneira efetiva, um passo diferente por comprimento unitário. A quantidade da redução do passo de filete de flanco de carga é equivalente à constituição, por exemplo, trinta graus de quatro filetes por comprimento unitário.
