Abstract

"JUNTA ROSCADA PARA TUBO". Junta roscada para tubo, para a conexão de uma tubulação (6) que apresenta uma extremidade de conexão com um boleado anelar (8) circunferencialmente conformado, consistindo de uma tubuladura de conexão (2) e de uma parte de atarraxamento de capa (4), que pode ser atarraxada com a tubuladura de conexão (2), para a retenção vedada da tubulação (6). A tubuladura de conexão (2) apresenta uma abertura de recepção (1 6) com uma face escalonada radial (18) para o apoio axial de uma face frontal (10) da tubulação (6) e com um cone interno (20) que se alarga para fora desde a face escalonada (18). A tubulação (6) pode ser tensionada com o boleado anelar (8), com fecho devido à forma, entre a tubuladura de conexão (2) e um anel de apoio (22) que se assenta sobre a tubulação (6) entre o boleado anelar (8) e a parte de atarraxamento (4). O anel de apoio (22) forma com o boleado anelar (8) uma face de encosto (24) que se situa de tal maneira, com relação ao eixo geométrico de atarraxamento (12), em um ângulo (<244>) claramente maior do que 45<198>, sendo que este ângulo (a) se situa preferentemente na região de pelo menos 80<198> até no máximo 100<198> e é de especialmente aproximadamente 90<198>.
