Abstract: A swaging mandrel is inserted in a tube confined by a tube sheet or other surrounding structure. A pair of seals define the axial limits of a hydraulic pressure zone within the tube sheet in which radial expansion of the tube takes place in response to fluid pressure. At one side of the tube sheet, an elastomeric ring can extend beyond the tube sheet and, in response to the fluid pressure, produce an attenuated radial expansion force that bulges the tube. At the primary side of the tube sheet, an elastomeric ring, in response to the fluid pressure, causes arcuate segments of a cylinder positioned beyond the tube sheet to expand radially and flare the tube at the opposite side of the tube sheet.

Abstract: A unitary tool assembly is disclosed for making up bell and spigot joints to couple adjacent pipe sections. The tool includes forward and rearward pipe engaging subassemblies and an intermediate linkage mechanism. The forward subassembly, which straddles a pipe section having a bell end, includes a reciprocative actuator which, through the linkage mechanism, selectively causes toothed cams carried by the rearward subassembly to engage and disengage a pipe section having a spigot end and straddled by the rearward subassembly. When the actuator delivers a power stroke, the toothed cams securely engage the pipe section with the spigot end, and the rearward subassembly is simultaneously pulled toward the forward subassembly such that successive strokes of the actuator effect a ratcheting action in which the bell and spigot joint is made up through a series of stepwise movements of the pipe sections together.
