The second end (74) includes a key portion (36) that is adapted to engage the keyway (32), thereby impeding the rotation of the first pipe (20) relative to the second pipe (22). The pipe and pipe coupling assembly (10) further includes a coupling member (34) adaptable to be rotatably attached to the second end (74).
