PPI Offers Free Course on Selecting, Specifying HDPE for Power, Communications

The Plastics Pipe Institute Inc. (PPI) launched a new Continuing Education Unit (CEU)-style course about design, installation and specification of high-density polyethylene (HDPE) conduit and duct. Selecting & Specifying HDPE Conduit for Power and Communications Applications can be downloaded free from the PPI website.

This course provides guidance to designers and specifiers of nonmetallic raceway (polymer conduit) for power and communications projects when selecting and specifying HDPE conduit products. Topics discussed include product capabilities and benefits, common applications, typical installation techniques and the latest industry standards.

“This is an impartial course that does not promote any particular manufacturer or product,” said Lance MacNevin, P.Eng., PPI Power & Communications Division, director of engineering. “It is designed according to AIA Guidelines for continuing education and provides a full 60 minutes of valuable information. Content is based on the expertise of our member firms, with a strong focus on industry standards, as well as existing PPI publications.”

In addition, the course describes how to make the best use of recent PPI publications PPI TN-50: Guide to Specifying HDPE Conduit and PPI MS-5: Model Specification for HDPE Solid Wall Conduit for Power and Communications Applications.

HDPE conduit, also known as PE conduit, is the preferred material to house and protect electrical power and communications cables in typical applications such as fiber optic, power utilities, telecommunications, CATV, SCADA, FTTH, ITS, highway lighting, and other underground utilities. Benefits of HDPE conduit, according to PPI, include availability in long lengths without joints, high strength, flexibility, proven reliability and installation toughness. PE conduit, including Cable in Conduit (CIC), is widely used in trenching, horizontal directional drilling (HDD) and plowing installation methods.

The course can be downloaded for free from PPI’s website, on the Power & Communications Division Education page at
