Abstract
A swivel coupling for connecting misaligned pipe sections, the swivel coupling having a socket member with an integral flange, a ball member which mates with the socket member and a ball swivel flange which holds the ball member in contact with the socket member. The ball member has a spherical outer surface which is complementary to a spherical inner surface of the socket member and allows the ball member to swivel while remaining in mating contact with the socket member. The ball swivel flange has an inner spherical surface which includes an equatorial band wide enough to capture the spherical surface of the ball member within the ball swivel flange. A sealing ring is positioned between the ball member and socket member to ensure a proper seal. The flange of the socket member is bolted to the ball swivel flange to hold the swivel coupling assembly together and to draw the ball member and socket member into sealing contact.
