Title:
APPARATUS AND METHOD OF DEPLOYING A PIPE WITHIN A BOREHOLE
Document Type and Number:
WIPO Patent Application WO/2024/003516
Kind Code:
A1
Abstract:
Lining pipes (103) are routinely pulled through HDD boreholes from one end. As HDD borehole distances get longer, the total amount of friction experienced by the pipe will increase and therefore greater forces/stresses are applied to the pipes (103). For a given material and diameter of pipe (103), conventionally, the only way to handle these stresses is to increase the wall thickness of the pipe (103). The present invention provides at least one gripping device (201) on a line (107), movable through the interior of a pipe (103), and configured to grip an interior of the pipe (103). In this way, the gripping device (201) may be used to grip a pipe (103) at a point spaced from an end thereof, thereby reducing tensile forces on the pipe.
