A pipe alignment tool for aligning abutted ends of first and second pipe sections to be joined includes a clamp member adapted to be clamped circumferentially about the first pipe section and one or more pipe engaging members mounted on the clamp member adapted to extend across a seam between the abutted ends of the first and second pipe sections to overlap the second pipe section. A bearing member is rotatably supported on each pipe engaging member for rolling contact with the second pipe section to assist in positioning the second pipe section relative to the first pipe section. The clamp member may be formed of modular sections connected circumferentially in series in which each modular section defines a mounting location upon which a pipe engaging member can be removably attached.
