System and method for installing pipe liners
View Patent ↗A method and apparatus for moving pipe rehabilitation objects, such as a pipe liner through a host pipeline. Flexible tubing is used to connect to the pipe rehabilitation object and to apply a force to cause the pipe rehabilitation objection to move through host pipeline. The flexible tubing is also capable of conveying a fluid, such as a lubricant through the tubing.
1 . A system for moving pipe rehabilitation objects through a host pipeline, the system comprising:
a lubrication dispenser configured to dispense lubricant onto an interior surface of the host pipeline from within the host pipeline;
a lubricant tank;
flexible tubing configured to provide fluid communication from the lubricant tank to the lubrication dispenser within the host pipeline, the flexible tubing being further configured to be connected to a pipe rehabilitation object and for moving the pipe rehabilitation object within the host pipeline as the flexible tubing is moved along the host pipeline; and
a pump for pumping lubricant from the lubricant tank through the flexible tubing so that the lubricant is dispensed from the lubrication dispenser when the flexible tubing is connected to the pipe rehabilitation object and moves along the host pipeline to thereby lubricate the interior surface of the host pipeline.
2 . The system as set forth in claim 1 further comprising a flexible tubing take-up configured to pull the tubing and the pipe rehabilitation object through the host pipeline.
3 . The system as set forth in claim 2 wherein the flexible tubing take-up comprises a powered reel on which the flexible tubing may be wound.
4 . The system as set forth in claim 1 wherein the pipe rehabilitation object is a liner and the flexible tubing is configured to be attached to the liner for pulling the liner through the host pipeline.
5 . The system as set forth in claim 1 further comprising a tubing management apparatus, the tubing management apparatus and flexible tubing being configured to push the host pipeline preparation apparatus the full length of the host pipeline.
6 . The system as set forth in claim 1 further comprising a hydrostatic testing seal configured to seal a longitudinal section of the host pipeline.
7 . A system for moving a liner in a host pipeline, the system comprising:
flexible tubing configured to carry fluid internally through the flexible tubing, the flexible tubing being configured to connect to the liner;
a pull head attached to the tubing and operatively connected to the liner; and
apparatus configured to move the flexible tubing through the host pipeline thereby to apply force through the tubing and the pull head to the liner to pull the liner into the host pipeline so that the entirety of the tubing is located forward of the liner in the direction the liner is pulled into the host pipeline.
8 . The system as set forth in claim 7 wherein the apparatus comprises a flexible tubing take-up configured to pull the flexible tubing through the host pipeline.
9 . The system as set forth in claim 8 wherein the flexible tubing take-up comprises a powered reel on which the flexible tubing is configured to be wound.
