A pipe flange alignment guide to assist in connection of adjoining bolted pipe flanges is described. The guide is comprised of first and second semi-circular body sections joined together by a clamshell hinge and a buckle assembly. Each body section has a flared bottom that forms a conical opening when the body sections are positioned around adjoining flanged pipe segments. The top of each body section forms a semi-circular cover with opening edges having a plurality of spaced apart scallops. The scallops conform to the bolt hole pattern of the adjoining pipe flanges and serve as an alignment guide for the flange attachment bolts.

Swivel assembly and disassembly apparatuses for assembly and disassembly of a swivel include an apparatus base, a bearing collection basin carried by the apparatus base, a swivel head mount carried by the bearing collection basin, a swivel assembly/disassembly head carried by the swivel head mount and a swivel mounting mechanism carried by the swivel assembly/disassembly head.

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.
