    摘要: A pipe connector for offshore risers has conical thread forms. The connector has a pin with a nose, an external shoulder, and conical first and second pin threaded sections. The first and second pin threaded sections are axially separated by a pin intermediate section that is free of threads. The first and second pin threaded sections are formed on a single continuous taper and on a continuous helix. The intermediate section is also conical and at the same taper as the pin first and second threaded sections. The connecter has a box with a rim, an internal base, and a conical receptacle between the rim and the base. The conical receptacle has first and second box threaded sections that make up with the pin threaded sections. The box also has an intermediate section between its first and second threaded connections that is free of threads. The intermediate sections make up with radial interference. Upper and lower metal-to-metal sealing surfaces are located at the nose and at the base of the pin.

    摘要: A pipe connector has a rigid seal/support ring mounted on its pin. The pin has a nose and external threads extending rearward from the nose. The rigid seal/support ring is fixedly mounted on an exterior portion of the pin farther from the pin nose than the pin threads. The rigid seal/support ring is installed by a shrink- or press-fit and has a tapered exterior seal surface. The box has a rim and internal threads that mate with the external pin threads. The box has a seal surface for engaging the seal surface of the rigid seal/support ring to form an external seal. The box also has a seal surface to form an internal seal with the nose of the pin.

    摘要: A gage for measuring a diameter of a workpiece has a pair of parallel spaced apart side rails. A pair of block sets is mounted between the side rails and spaced apart from each other. A pair of arms extends transverse to the rails through mating profiles in the blocks of each block set. The arms are slidable in a transverse direction to the side rails. Each block set can slide along the side rails and has a single fastener that secures the blocks to the side rails and the arms to the blocks in a desired position. Drag brakes between the blocks and the side rails prevent the components from sliding of their own weight while the fasteners are loosened. The block sets and arms are rotatable 180 degrees about the fasteners when loosened to accommodate outside and inside measurements.
