Fluid conveying pipes and processes of forming such pipes using friction stir welding. The fluid conveying pipes are formed from a pipe section that includes a first barrel coaxially and concentrically disposed within a second barrel. The first barrel and the second barrel are each formed from one or more sections or plates where longitudinal extending facing edges of the plates are friction stir welded (FSW) together along a seam(s) that extends longitudinally from the first end to the second end thereof. A plurality of the pipe sections can be connected together end to end using circumferential FSW seams to form a pipe.
