A base reformer assembly, and/or a base reformer roller die unit, includes a generally toroid chuck, a roller die, and a roller die unit actuating assembly. The roller die is movably disposed within the chuck. The roller die unit actuating assembly is structured to actuate the roller die. The roller die unit actuating assembly is operatively coupled to the roller die. Further, all elements of the roller die unit actuating assembly have a robust cross-sectional area.

A rotary crimping tool assembly includes a tool housing defining a crimping chamber, and one or more crimp wheels within the crimping chamber. The crimping chamber is configured to receive the portion of the structure in proximity to the crimp wheel(s). The crimp wheel(s) are configured to be pressed into and rotated relative to the portion of the structure to form one or more crimps in the portion of the structure.

One method for producing a bimetallic tubular component comprises hot isostatic pressing an assembly comprising two concentrically-positioned tubes including an inner tube comprising a corrosion-resistant nickel alloy, and an outer tube comprising a steel alloy, thereby forming a bimetallic tubular preform. The bimetallic tubular preform is flowformed, thereby forming a bimetallic tubular component comprising an inner corrosion-resistant nickel alloy layer and an outer steel alloy layer.

A method of producing a bimetallic tubular component includes providing a first tubular workpiece having an inner diameter and a second tubular workpiece having an outer diameter. The first and second tubular workpieces have dissimilar cold-working processing parameters. The method further includes diffusion bonding the inner diameter of the first tubular workpiece to the outer diameter of the second tubular workpiece, and flowforming the diffusion bonded tubular workpieces to form the bimetallic tubular component.

A manufacturing method of a seamless metal pipe includes determining whether a preceding-stage stand group is used in outer diameter reduction or in thickness reduction of a hollow shell; and performing elongating on the hollow shell, into which a mandrel bar is inserted, based on the determination. In addition, in the elongating, when the preceding-stage stand group is used in the outer diameter reduction, the hollow shell is rolled in a state where an inner surface of the hollow shell does not come into contact with the mandrel bar in the preceding-stage stand group, and the hollow shell is rolled in a state where the inner surface of the hollow shell comes into contact with the mandrel bar in the succeeding-stage stand group.

An apparatus, method and composition for long length tubing includes continuous production of long length seamless aluminum tubing suitable for use as coiled tubing in hydrocarbon wells. A 2XXX aluminum alloy may be used in combination with a continuous casting/extrusion apparatus using aluminum from a melt. Other metals may be used, as well as continuously cast rod from a casting wheel and belt or conform extruder, which is processed to form a hollow and then sized by drawing.
