ABSTRACT:
A clamping assembly particularly useful for aligning abutting ends of pipe sections to form a mitered joint. A plurality of individual clamp assemblies are clamped in circumferentially spaced positions upon one pipe section by a circumferentially extending chain, each clamp assembly having an elongate jack arm which can be clamped in selected positions of circumferential and axial adjustment upon the one pipe section so that the jack arms may be projected to different axial distances from the chain into operative engagement with a second pipe section lying in a plane inclined to axis of the one pipe section.
