摘要： A joint seal (10) has a through bore (12) and two spherical spaced convex surfaces (20, 22) which mate with respective concave spherical surfaces (38, 44) on a pair of adjacent flanges (26, 42). The flanges are welded to and about the periphery of corresponding spaced pipes (6, 8) one of which is inserted in the bore (12) of the seal. The flanges are joined by two bolts (52), one flange (26) being fixedly secured to the bolts (52) and the other resiliently movably secured to the bolts by a pair of springs (62) to permit that other flange (42) to rotate in response to rotation of the pipe (8) affixed thereto. The one flange forms a static wedge-like seal joint with one of the pipes and the other flange a dynamic seal joint with the respective seal spherical surfaces, the spherical seal and flange surfaces being urged together in wedged relation by the springs.
