scope:

High-density polyethylene (HDPE) conduit is the preferred material to house and protect electrical power and telecommunications cables within. It offers unmatched corrosion and chemical resistance, is flexible, durable and available in long reel lengths to reduce joints and installation time. HDPE conduit is available in a variety of sizes, wall types, colors, and lengths.

HDPE conduit's flexibility allows it to be coiled and provided in long lengths, thereby improving installation efficiencies. This technical note provides information about ovality caused by the coiling of HDPE conduit and cable in conduit, and methods for mitigating ovality and coil-set prior to and during installation.
