THREADED CONNECTIONS AND METHODS

摘要

Couplings and/or connections and related methods are disclosed that include a female component engaged with a male component. A first shoulder of the female component abuts a first complementary shoulder of the male component to form a first radial real. A second shoulder of the female component abuts a second complementary shoulder of the male component to form a second radial seal. A sealing surface of the female component abuts a complementary sealing surface of the male component to form an axial seal disposed between the first and second radial seals. Plastic and/or elastic deformation of the complementary sealing surface of the male component can facilitate formation of the axial seal while preventing galling of threads or other portions of the male and female components.
