The micro ducts are surrounded by a layer of moisture-barrier metallic or non-metallic tape and a flexible sheath of black HDPE. DI ducts can be installed in pre-existing pipes or sub-ducts
Has a relatively thin sheath layer wall thickness, typically 1.7mm. Generally applicable to wear into the cement pipe, steel pipe, PVC pipe within the existing pipe hole expansion.
Commonly used direct-mounted bobbin configuration:
