EMTELLE MICRODUCT TUBING, DIRECT BURIAL

System Features

• Flexibility - When wrapped around a 10d mandrel (where d = tube diameter) there is no kinking or damage and an appropriate diameter ball passes completely through the microduct.
• Pressure - Micro duct withstands 17 bar air pressure underwater for 2 hours without leaks.
• Friction - Low friction lining material used to increase fibre blow distance.
• Crush - After a 1000N load (used on Polyethylene microducts) and 400N load (used on Low Fire Hazard mirco ducts) for 1minute, the residual deformation of the microduct does not exceed 15% measured within 1 minute of unloading.

Direct Burial Microducts (DBT)

Assembly of 5mm PE Tubes, each with low friction performance. The Tube bundle is surrounded by a 150 micron aluminium moister barrier layer bonded inside an inner sheath of MDPE. Over the sheath is a layer of Nylon to provide Termite Resistance & mechanical strength with a final outer layer of HDPE. Non-Metallic versions are also available on request.
