A method of fabricating a conduit comprises steps of attaching a first tubular-outboard-ply end of a tubular outboard ply to a first inner collar portion of a first collar with a third weld and attaching a second tubular-outboard-ply end to a second inner collar portion of a second collar with a fifth weld. The method additionally comprises steps of interconnecting the first inner collar portion and a first outer collar portion of the first collar with a first weld and interconnecting the second inner collar portion and a second outer collar portion of the second collar with a sixth weld. The method also comprises attaching a trimmed first corrugated-inboard-ply end to the first outer collar portion with a second weld, attaching a trimmed second corrugated-inboard-ply end to the second outer collar portion with a fourth weld, and communicatively coupling a first sensor with an interstitial space.

A method for cold working pipe elements use two or more cams, each having a gear which meshes with a pinion to turn all of the cams. Each cam has a cam surface with a region of increasing radius and may also have a region of constant radius extending around a cam body. Each cam may also have a traction surface extending around a cam body. The method includes contacting the pipe element with a plurality of cam surfaces simultaneously at a plurality of locations on the pipe element and rotating the pipe element, thereby simultaneously rotating the cam surfaces. Each cam surface engages the pipe element with an increasing radius and a region of constant radius if present to deform the pipe element and form the groove.

A method of radial incremental forming a component having a component inner mold line (IML) includes providing a mandrel having geometry configured to mate with the IML. The method also includes inserting the mandrel into a tubular workpiece composed of a formable material, to thereby sleeve the workpiece over the mandrel. The method additionally includes mounting the workpiece sleeved over the mandrel onto a drive mechanism configured to rotate the mandrel and having a forming tool configured to shift relative to the workpiece. The method further includes regulating, according to provided toolpath instructions, the drive mechanism to rotate the workpiece sleeved over the mandrel in concert with shifting the forming tool relative to the workpiece to incrementally deform the workpiece therewith over the mandrel and thereby form the component. A tool system having an electronic controller may employ the subject method to radially incrementally form a component.

A device for cold working pipe elements has two or more cams, each having a gear which meshes with a pinion to turn all of the cams. Each cam has a cam surface with a region of increasing radius and may have a region of constant radius extending around a cam body. Each cam also has a traction surface extending around a cam body. A region of reduced radius in each cam surface is aligned with a gap in the traction surface of each cam. The regions of reduced radius and gaps provide clearance for insertion and removal of the pipe element between the cams to form a circumferential groove when the cams are rotated.
