Abstract: A magnetic forming system (10) for creating a fluid circuit joint between a tube and a fitting includes an induction coil (12). The induction coil (12) may form a first stage electromagnetic current. A field concentrator (132) may focus the first stage electromagnetic current to form a second stage electromagnetic current. An insert (136) may focus the second stage electromagnetic current to form an electromagnetic field. The electromagnetic field forms the fluid circuit joint. The induction coil (12) may be insertable within the tube, generate an electromagnetic field, and impose the electromagnetic field on and to expand a portion of the tube within the fitting to form the fluid circuit joint. The system (10) may include a receptacle (54) that is external to the tube and the fitting. An insert (56) may be mechanically coupled within the receptacle (54) and limit the outward expansion of the tube and the fitting.

Abstract: For jointing a tubular member such as a flange-carrying device or a length of pipe to the end of a submerged pipeline, explosive jointing is used. The annular space between the tubular member and the end of the pipeline is closed off by internal and external seals, cleared of sea water, flushed and dried before the jointing charge is detonated, thus facilitating jointing and avoiding contamination of the weld. The bores of the pipeline and tubular member are filled with inflatable bags or other waterdisplacing members to absorb the shock of the explosion.

Abstract: A method providing a first tubular workpiece having a first weld surface at an end thereof, and a second tubular workpiece having a second weld surface at an end thereof; aligning the workpieces on a common axis with the weld surfaces facing each other, rotating one workpiece about the axis relative to the other workpiece, and engaging the first and second weld surfaces such that the rotation raises the temperature at the weld surfaces to create a weld interface; and ceasing the rotation and allowing the weld interface to cool to weld the workpieces together at the interface. The first weld surface is an apex region of an annular projection at the end of the first workpiece, on a longitudinal section through the aligned workpieces the annular projection having a profile in which radially inner and outer side surfaces of the annular projection taper towards the apex region.

Abstract: There is disclosed fluid distribution junctions and methods of assembly therefor. Flexible conduits connect to the junctions, and a consumable subsystem of the junction, conduits and receptacle caps or other connectors may be pre-assembled for ease of use. A subassembly is formed by coupling a plurality of flexible tubular conduits to a plurality of fluid connectors of a fluid junction, the fluid junction having an inner fluid plenum chamber leading to the fluid connectors. Two shells are sandwiched on opposite sides of the subassembly, the shells having mating concave receiving surfaces that together conform around each of the fluid connectors and clamp the tubular conduits onto the circular beads. Juxtaposed joint surfaces on each pair of mating concave receiving surfaces are bonded together such as with sonic welding to make the fluid distribution junction assembly.
