ABOUT HDPE CONDUIT
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, colors, dimensions and lengths.
HDPE conduit products are manufactured in a wide range of colors, lengths, diameters and wall types. These apply not only to the protective conduit but also to innerduct, if present.
HDPE Conduit types include:
Various colors or stripes can be used to identify the network operator or the type of cable used in the conduit such as telecommunications (e.g. orange) and power (e.g. red or black with red stripe).
HDPE conduit standards such as ASTM F2160 specify the dimensions for HDPE conduit. Various sizing systems exist, including IPS types SDR9, SDR11, SDR 13.5, DR 15.5, SCH 40 and SCH 80, "True Sized" and SIDR. For IPS types, wall thickness is described by the Dimension Ratio (DR) which typically ranges from DR 9 to 17 for conduit up to 12" in diameter. The lower the DR number, the thicker the wall, relative to other wall types.
Polyethylene Conduit and Innerduct help sustain important aspects of our lives including communications, power, and electrical networks. HDPE pipe characteristics provide long-term protective conduit where its flexibility aids installation while maintaining excellent toughness and stiffness. Because of HDPE's inherent design, the conduit will protect the ever expanding systems as communities and technologies continue to grow.
HDPE conduit is flexible which allows ease of installation in existing pathways, yet its stiffness can withstand crush forces at the calculated level for buried applications.
HDPE conduit is installed along highways or roads and in buildings. It is used to protect Power Distribution lines (600V secondary, <69kV primary) and telecommunication lines (network backbones), landline (wireline) and broadban; such as DSL Internet and CATV. The different installation methods are project specific and dictate what strength conduit is used.
Horizontal Directional Drilling (HDD) minimizes the impact to the surrounding area including less interruptions to traffic. This methods installs long lengths of conduit as much as 1,000-ft bores.
