Abstract
A joint assembly for joining two pipes together comprises first and second liners and first and second pipe flanges. Each liner includes a sleeve and a liner flange with the liner flange coupled to one end of the sleeve. The first liner may be positioned within a first pipe and the second liner may be positioned within a second pipe. Each pipe flange includes an inner surface and an opposing outer surface with a plurality of circumferentially spaced plateaus positioned thereon. Each plateau has a height above the outer surface. The first pipe flange may be coupled to one end of the first pipe and the second pipe flange may be coupled to one end of the second pipe. The first and second pipe flanges may couple to one another such that each plateau on the first pipe flange contacts a corresponding plateau on the second pipe flange.
