MDU Installation Techniques
Learn more about how conduit is used in MDUs. This type of construction has its own special needs and Dura-Line has specialty products to fit every scenario.
INTERIOR MICRODUCT INSTALLATION
Interior MicroDucts are designed to be used in MDU (Multi-Dwelling Units) and MBU (Multi-Business Units) applications. Interior MicroDucts can be used in Greenfield (New Construction) and Overlay (Brownfield) markets. LowSmoke Zero Halogen (LSZH) MicroDucts are designed exclusively for interior use.
MicroDuct Characteristics:
- SILICORE® super slick permanent lining
- Internal longitudinal ribbing
- Standard with a Pull String
- LSZH MicroDucts are opaque white in color
MicroDuct Placement Guidelines
When placing Dura-Line MicroDucts, the length can vary based on the configuration of the MicroDuct run.
- The run should not exceed 60 m
- No more than 8 - 90º bends in 60 m
- No more than 16 - 45º bends in 60 m
- Each bend should have at least a 35 cm radius
- Long sweeping bends are recommended
Make Sure:
- Use smooth bends with the MicroDuct routing
- No kinks or deformities in the pathway
- Proper strapping and support of the MicroDucts
- Properly label MicroDucts and pull lines on both ends
Pathway Routing Considerations
- Place runs to minimize the amount of MicroDuct required
- Choose the path that will require the minimum number of bends
- Avoid mechanical damage, hot water pipes, steam pipes, metal gratings, etc.
- Make sure the MicroDucts will not interfere with drywall installation
- Drill your right of ways in a manner that will not interfere with the bend radius or add bends
