ABSTRACT:
An apparatus and method for forming grooves in a pipe for receiving mechanical pipe clamps are disclosed. The apparatus includes a holding fixture for securing the pipe and a carriage rotatably mounted on the holding fixture. Two arms are pivotably mounted on the carriage and extend on opposite sides of the pipe. Each arm has a grooving roller rotatably mounted thereon. An actuator connects the arms and forces the grooving rollers into engagement with the pipe. The carriage, arms, actuator and grooving rollers are rotated about the pipe in an orbit to form the circumferential groove. The method steps include forcing the grooving roller into the surface of the pipe at a fixed rate per revolution of the grooving rollers about the pipe in the orbit.
