Abstract: A pipe end fitting assembly that includes an outer body having an outer surface, an inner surface defining a first bore, and an end surface, and an inner body having an inner surface defining a second bore and an outer surface. A portion of the inner body outer surface is secured to the outer body inner surface. A passage formed in the outer body includes a first portion extending from the end surface and parallel to the first bore, and a second portion extending from the outer body outer surface to the passage first portion. A pipe end is disposed around and secured to a portion of the inner body outer surface. A jacket is disposed around the pipe and has an end secured to the outer body outer surface. The passage portions are in fluid communication with each other and a space between the jacket and the pipe.

Abstract: A drum assembly having a post, and first and second spoke frames. Each of the first and second spoke frames includes expandable spokes and immovable spokes, extending away from the post. Each expandable spoke includes a distal end movable between a retracted position and an extended position. A plurality of first drum segments each are mounted to the distal end of one of the expandable spokes of the first spoke frame and to the distal end of one of the expandable spokes of the second spoke frame. A plurality of second drum segments each mounted to an end of one of the immovable spokes of the first spoke frame and to an end of one of the immovable spokes of the second spoke frame. Mechanical actuators, extending between the post and either the expandable spokes or the first drum segments, move the expandable spokes between the retracted and extended positions.
