摘要： A pipeline misalignment flange 10 includes a socket member 12 having a first smaller spherical internal surface 24, the socket member having a first face 34 surrounding the first substantially spherical internal surface, the first face having a recessed channel 36. A retainer member 16 includes a second larger spherical internal surface 38, the socket member and the retainer member being fastened together. A ball member 14 includes a first smaller spherical external surface 40 for engaging the socket member and a second larger spherical external surface 42 for engaging the retainer member. The second larger spherical external surface includes an axially protruding portion 44 with an undercut 46, the ball member being pivotable relative to the socket member such that the axially protruding portion of the second larger spherical external surface is received in the recessed channel.
