HDPE PLASTIC CONDUIT TYPES & DESIGN
HDPE conduit products are manufactured in a wide range of lengths, diameters and strength. These apply not
only to the protective conduit but also innerduct.
HDPE Conduit types include:
Various colors identify the network operator or the type of cable used in the conduit such as telecommunications (orange)
and power (red or black with red stripe).
ASTM International F-2160
specifies the dimensions for HDPE conduit which includes IPS,
SCH 40 and SCH 80, "True Sized." For IPS, wall thickness is described by the
Dimension Ratio (DR)
which typically ranges from DR 9 to 17 for conduit up to 12" in diameter.
Conduit System Design
The physical design of HDPE conduit is dependent on the installation method which includes trenchless technology, chute plowing and open trench.
