Abstract
"CONEXãO DE TUBO PARA TUBULAçãO DE AçO INOXIDáVEL". Uma conexão de tubo que usa apenas dois componentes, especificamente, um corpo de conexão e uma porca de conexão. A porca e o corpo são adaptados para serem acoplados de forma roscada em conjunto por uma rotação relativa entre eles. A porca inclui um anel de sujeição de tubo integral que coopera com uma superfície de came no corpo, quando a conexão é constituída. A superfície de came, preferencialmente, tem um ângulo de came agudo. O anel é radialmente comprimido contra a parede externa de tubo, para formar um selo e uma sujeição de tubo firme. O anel também forma um selo de tipo de contato em linha contra a superfície de came. O anel é projetado para ter uma ação de articulação e para se deformar plasticamente, durante um aperto, para embutir na tubulação, para uma excelente sujeição de tubo, e uma zona de expansão ou de casquilho axialmente adjacente, que isola qualquer concentrador de tensão resultante da ação de embutimento de efeitos de vibração. Os componentes de conexão e, particularmente, o anel, podem ser cementados, a conexão pode incluir um aspecto de autocalibração, para indicar um aperto suficiente, para impedir um aperto excessivo. Também é provida uma conexão de tubo de ferragem única, que usa uma superficie de came aguda e é pelo menos cerca de 3,3 vezes mais dura do que a extremidade de tubo de aço inoxidável.
