A system for inspecting an interior surface of a girth weld region of a pipeline includes a robot that includes a scanner mounted on a carriage for scanning the interior surface of the girth weld region to generate surface profile data. A profile analyzer receives the surface profile data and outputs an indication of whether the interior surface of the girth weld region is suitable for being coated. In some embodiments, an imaging system captures images of the girth weld region as it is being scanned. In a method of coating the girth weld regions of a pipeline, the images of a girth weld region found to be unsuitable for being coated based on the scanning data are used to certify whether the girth weld region is suitable for being coated.

Pipe joint inspection

A pipe bending machine has a stiff-back which is driven by a pivoting wedge. A linkage applies force from the actuator to the wedge in a direction parallel to a longitudinal axis of the stiff-back. The stiff-back pivots on a first fulcrum and the wedge slides on a bed which pivots on a second fulcrum. The actuator drives the wedge between the stiff-back and the bed to rotate the stiff-back at the first fulcrum and bend the pipe seated in the stiff-back against the pipe bending face of a die. The conversion of the longitudinal force applied to the wedge into a transverse force applied to the stiff-back provides a significant mechanical advantage which varies directionally as the stiff-back rotates about its fulcrum to maintain a constant force on the stiff-back.

A service body for a vehicle includes side packs, each of which is formed with a multi-panel face which includes a side panel, a front panel and a back panel. The panels of the multi-panel face are formed integral by laser cutting the face from a single sheet of metal. L-shaped compartment panels are constructed by forming a compartment divider at right angles to a recessed doorjamb. The recessed doorjambs are welded to the interior surface of the side panel. Top, back and bottom panels are welded to flanged edges of the multi-panel face.
