Handbook of Polyethylene Pipe
PPI's Handbook of Polyethylene Pipe describes how polyethylene piping systems continue to provide utilities with cost effective, sustainable and reliable solutions to build and rehabilitate the underground infrastructure. While Chapter 14 is specifically on Duct and Conduit, other chapters (e.g. Chapter 3 on Material Properties and Chapter 12 on Horizontal Directional Drilling) also apply to conduit.
Chapter 14 - Duct and Conduit
Chapter 12 - Horizontal Directional Drilling
Chapter 3 - Material Properties
HDPE Conduit & Duct Handling Guide
The HDPE Conduit & Duct Handling Guide (also known as PPI TN-58) provides information about general handling guidelines for reels and coils of HDPE conduit and duct, including the potential risks when cutting open such reels and coils. It also covers a limited range of safety issues regarding the unloading, unwinding, straightening and cutting of PE conduit and duct.
The Conduit Design Calculator is a software tool that aids in determining the most appropriate wall thickness of high-density polyethylene (HDPE) conduit installed via horizontal directional drilling (HDD) techniques.
