  • Patent number: 6427993
    Abstract: A pipe fitting apparatus includes first and second connector units for releasable connection to respective first and second pipe sections adjacent pipe ends to be coupled, so as to hold the pipe sections relative to one another in the desired relative orientations during welding. Each connector unit has a groove on one face for location against the outside of a pipe, with the longitudinal groove axis extending parallel to the axis of a pipe to which it is secured. The units are adjustably secured together by a pivot coupling having a pivot axis extending transverse to the groove axis for pivotal adjustment of the orientation of the second connector unit relative to the first connector unit, whereby the relative orientation of the first and second pipes to be coupled can be adjusted. A releasable locking device releasably secures the second connector unit at a selected orientation relative to the first connector unit.
