Determining the appropriate conduit wall thickness can be a time-consuming and sometimes arduous task in preparing for a horizontal directional drilling job. Fortunately, the Plastics Pipe Institute has released a free software tool that aids in determining the best wall thickness of high-density polyethylene conduit being installed: the Conduit Design Calculator.
Published on the company’s website at www.plasticpipe.org/conduitcalc/ or at www.conduitcalc.com, the calculator simplifies complicated calculations into an easy-to-use online application.
The calculator automates the Mini-HDD calculations pioneered by Dr. Larry Slavin and described in PPI TR-46. It uses inputs such as directional changes in the underground bore path, drill rod diameter,
