Standard HDPE
Standard HDPE Conduit
Dura-Line manufactures standard High Density Polyethylene (HDPE) conduits for standard installation applications such as underground, as innerducts in existing conduits, or corrugated products to use in congested areas. HDPE is a flexible and resilient material. It provides superior resistance to natural or mechanical damage, and has excellent low temperature properties to handle cold weather.
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.
Smoothwall
Our most popular HDPE duct, Smoothwall is available with an optional Silicore permanently lubricated lining. The inherent properties of HDPE make gradual bends without special equipment, and provide outstanding long-term cable protection from shifting ground, rock, and root impingement. These ducts perform well in all environments, aerial, direct buried and underground.
- Size Range: 20 mm to 250 mm
- Available with Silicore – permanently lubricated lining
- Factory Pre-Installed Cable or Tape options
Smooth Out/Ribbed In
Our popular HDPE duct with a smooth outer wall and internal longitudinal ribs for a reduced coefficient of friction. These ducts perform well in all environments, aerial, direct buried and underground.
FEATURES
- Manufactured from flexible HDPE, makes gradual bends without special equipment
- Ribbed in maximized for greater pulling and jetting distances, reducing friction
- Ribs direct airflow around the cable during jetting and helps minimize contact with the duct wall
- Available with UV protectant for aerial/lashed placement
- Includes SILICORE permanent lubricated lining
Tornado Plus
Tornado Plus is specially designed to facilitate faster cable blowing. Developed by Dura-Line’s research team in collaboration with the Indian Institute of Technology, Tornado Plus has outperformed conventional ducts in extensive field trials.
The revolutionary design of Tornado Plus creates an air cushion tornado effect, imparting an increased pulling force on the cable. The cable rides on the air cushion, eliminating contact with the duct, and greatly reduces the friction. Installations can see two times the cable blowing compared to conventional Smoothwall ducts.
Characteristics:
- Consistent and faster blowing speeds
- Further cable placing distances, up to double typical distances for faster network builds
- Lower stress on fiber – 30% less pulling force required than manual pulling
