Abstract
A device for connecting two pipes for carrying abrasive material under high pressure employs a flange member welded to an end of one of the pipes and a ring member welded to an end of the other pipe. The pipes and both members have the same internal diameter. One or both pipes may be cold formed into a curved shape. An outward-extending rib on the ring member and a shoulder on the flange member are encircled by a tension sleeve having an inwardly directed lip at each end. The tension sleeve comprises two semi-circular halves. One or more continuous circumferential bands encircle the tension sleeve to hold the two halves together against radial separation. An anti-friction bearing assembly between one of said lips and a shoulder on the ring member permits relative turning movement between said pipes. An axial projection on the ring member is received within a recess in the flange member, and seal means are provided between the projection and the recess.
