Subterranean fluid transport system and method of installation

Abstract

A subterranean fluid transport system, flange assembly and method of installation is disclosed. In some embodiments, the subterranean fluid transport system includes a pipe segment with a rigid outer surface and a flexible inner sleeve positioned within the borehole of the pipe segment. The flexible inner sleeve configured to expand and contract within the borehole of the pipe segment when fluid is transported therethrough.

What is claimed is: 
     
         1 . A flange assembly for connecting a plurality of pipe segments for subterranean fluid transport, the flange assembly comprising:
 a clamp ring configured to be positioned coaxially over a pipe end, the clamp ring having a first end, a second end, an inner surface and an outer surface defining a borehole extending between the first end and the second end of the clamp ring, the outer surface of the clamp ring having grooves embedded therein;   a flange member configured to be received over the clamp ring and detachably connected thereto, the flange member having a first end, a second end, an inner surface and an outer surface defining a borehole extending between the first end and the second end of the flange member, the inner surface of the flange member having grooves embedded therein; and   wherein the grooves of the clamp ring and the grooves of the flange member are configured to be detachably connected so as to lock the clamp ring to the flange member in a desired position such that fluid may flow therethrough.
