Variable diameter pipe clamp apparatus and torque module therefore
Abstract:
A combination for making up and breaking out pipe at an oil rig site includes a torque module and at least one pipe clamp apparatus. The torque module includes a pair of hydraulic motors, a torque transmission driven by the motors, a herringbone gear segment driven by the transmission to rotate the torque module, and a pair of clamp cylinders actuated by the transmission. The at least one pipe clamp apparatus is actuated by at least one of the clamp cylinders to apply a uniform gripping load around a pipe that is pipe diameter independent.
