    摘要： A support ring supports a welding ring to guide welding bugs around a coated pipe section. The support ring has a tubular body to support the welding ring, the body having substantially circular curvature around a longitudinal axis. At least one grounding extension connected to the body is offset longitudinally and radially outwardly with respect to the body and the longitudinal axis. This allows the grounding extension to lie radially outboard of a parent coating of the pipe section while the body encircles a cut-back end zone where the parent coating has been cut back. Pipe sections abutting end-to-end for welding can each be fitted with these support rings. This enables welding rings to encircle both of the cut-back end zones and allows effective grounding connections to be made without enlarging the cut-back end zones.

    摘要： A method is disclosed of measuring a hollow object such as a pipe including temporarily attaching to that object a reference target support such as a stencil that supports a plurality of scannable reference targets. When scanning the object with a movable scanner, most conveniently a hand-held scanner, the reference targets provide a positional reference for the scanner. A reference target support that is attachable to or movable along a hollow object has a display face presenting and supporting a plurality of scannable reference targets. The display face can stand up from a surface of the object or can lie against a surface of the object. The reference target support and the scanner can be movable together along a pipe as an internal inspection pig.

    摘要： An internal line-up clamp for welding pipe lengths end-to-end includes a clamp ring made up of a plurality of clamp ring elements that are angularly distributed around the circumference of the clamp ring. The clamp ring elements are divided into mutually opposed groups that are interdigitated such that the clamp ring elements alternate from one group to the other around the circumference of the clamp ring. A longitudinally-acting actuator system drives relative longitudinal movement of the groups to effect clamping expansion of the clamp ring by wedging interaction between the circumferentially-alternating clamp ring elements of the groups. By expanding the clamp ring in alignment with a weld plane between the abutting ends, the same clamp ring may be used to align the pipe lengths and to back a weld between them.
