HDPE Standard Conduit – Smoothwall Conduit, Corrugated Conduit, Ribbed Conduit – DuraLine

HDPE Standard Conduit

Dura-Line’s traditional HDPE Standard Conduit products for utilities are of superior-quality. While offering innovative designs to make installation faster, easier, and more productive, Dura-Line manufactures a broad range of sections.

Our most popular HDPE duct, Smoothwall is available with an optional SILICORE® ULF permanently lubricated lining. These ducts perform well in all environments, aerial, direct buried, and underground. Multiple wall thickness are available based on the application.

Smoothwall

  • Manufactured from flexible HDPE, makes gradual bends
  • Continuous lengths reduce joining costs
  • Excellent low-temperature properties
  • Outstanding long-term cable protection from shifting ground, rock, and root impingement
  • Provides a permanent pathway, simplifies cable repairs
  • Available with UV protectant for aerial/lashed placement

HDPE duct with inner and outer ribs. The internal longitudinal ribs for a reduced coefficient of friction, while the external ribs help prevent spiraling and reduce friction when pulling innerduct into larger conduits. Available with optional Silicore ULF permanently lubricated lining.

Ribbed In/Out

  • Manufactured from flexible HDPE, makes gradual bends
  • External ribs help reduce spiraling during duct installation and reduces installation forces when installed into conduit
  • Internal ribs reduce the the coefficient of friction
  • Continuous lengths reduce joining costs
  • Excellent low-temperature properties
  • Outstanding long-term cable protection

CoExtruded conduit is an ideal choice to provide visual utility or end use of conduit identification

CoExtruded

  • The co-extruded color layer provides a full exterior appearance
  • Color layer is made from same HDPE as inner wall – performance properties are unaffected
  • Total wall thickness = inner black thickness + external layer thickness
  • Color fastness and UV protection performance for co-extruded conduit is equal to full wall colors
