Abstract
A coupling assembly for mechanically coupling the plain end of a pipe, comprising a pair of standard forged flanges as basic components between which is disposed a wedge ring. One of the flanges is of the slip-on type and has associated with it a conical collet bore for receiving the wedge ring. When tension bolts assembled through the flanges are tightened the wedge ring is driven into the collet bore and tightly radially against the periphery of the pipe to thereby lock the coupling to the pipe.
