  • Lightweight pipe clamp
    Patent number: 5738386
    Abstract: A lightweight, portable clamping device assists in holding and reforming pipes in piping systems. The clamping device comprises a pair of semicircular clamp halves which are placed on the abutting ends of out-of-round pipe. The clamp halves are drawn together by tightening bolts on either side to align and reform the ends of abutting pipes. The clamping device can also be used to shape and hold the end of a single piece of pipe. A plurality of access ports around the perimeter of the device allow a welder to tack weld the ends of abutting pipes prior to welding.
