Abstract: A method for removing pipe tuberculation includes the initial step of preparing an access point in the existing pipe by digging to the pipe and sawing a section from the pipe or creating an access port. The section of the pipeline to have its tuberculation removed is isolated by closing valves or creating another access point and sealing the end. Then, a reaming tool is introduced to the interior of the pipe. The reaming tool is attached to a hollow rod string capable of producing moderate thrust and pullback force, and must also produce sufficient torque when rotated. A horizontal directional drilling or “HDD” machine on the surface or in a pit dug out for this purpose applies the aforementioned forces to the rod string.
