Abstract: A pipe alignment apparatus to align a pair of adjacent pipe ends together. The apparatus includes a first pair of arcuate frames joined together to move between an open position and a closed position. A second pair of arcuate frames joined together moves between an open position and closed position. A plurality of jackscrews is provided on the first pair of arcuate frames and on the second pair of arcuate frames. A plurality of adjustable turnbuckles extends between the first pair of frames and the second pair of frames.

Abstract: A hydraulic chain clamp apparatus for pipe sleeves for a pipe. The apparatus includes a clamping chain circumnavigating the sleeves and the pipe, the chain having a first end and an opposed second end. The apparatus includes a housing block with a chain lock mechanism securing the first end of the chain to the housing block. A hydraulic cylinder mechanism is connected to the housing block. The hydraulic cylinder mechanism is attached to the second end of the chain and is adapted to move the chain between a tightened, closed position and a loose, open position.

Abstract: A field portable pipe-mounted pipe cutting system with integral controls. The system includes a torch carriage assembly having a torch for cutting a cylindrical pipe. A saddle and cap ring assembly is secured to the pipe. A ring gear engages the saddle and cap ring. At least one drive gear engages the ring gear. A drive gear step motor rotates the drive gear. A motion control module controls movement of the step drive motor. The lead screw assembly moves the torch carriage assembly longitudinally parallel to an axis of the pipe. A lead screw step drive motor drives the lead screw assembly and a motion control module controls movement of the lead screw step drive motor.
