Parametric Dependency and Trends of HDD Pull Loads
Publication: Journal of Pipeline Systems Engineering and Practice
Volume 1, Issue 2
Abstract
The required pulling loads on pipes installed by horizontal directional drilling (HDD) are related to the route characteristics and various implementation parameters, some of which are directly controllable. The application of ASTM Standard F1962, Standard Guide for Use of Maxi-Horizontal Directional Drilling for Placement of Polyethylene Pipe or Conduit under Obstacles, Including River Crossings, has been conveniently employed to perform a parametric study to help understand the dependency of the pull loads on these variables and the corresponding installation characteristics. The results provide useful information to help focus on the more significant parameters that affect the pull loads, thereby helping to ensure successful installations. Some of the results are as expected, including the effectiveness of antibuoyancy techniques for dramatically reducing the required pull loads; other trends are less obvious. While the ASTM F1962 methodology is intended to be applicable for the placement of polyethylene pipe, the conclusions and guidelines may reasonably be extrapolated to other types of pipe.
