Innerduct is a type of HDPE piping used for electrical installation projects. It has a smooth inner surface that reduces friction on electrical cables as they are installed. Innerduct pipe's outer surface is corrugated, or ridged, for added strength. Innerduct pipe can also be used for culverts, storm sewers, side drains, septic tanks, and other drainage applications. Many varieties and sizes of innerduct are available commercially.
