HDPE Microduct

HDPE Microducts

General Description

It becomes more important than ever to better utilize the available space in your existing duct systems. Using MicroDucts is a better way to utilize that empty space, both today and tomorrow. It allows you to expand your fiber network as you bring on new customers. It enables you to increase bandwidth as your needs increase. And, it allows you to do it easily, without adding extra fibers that might never be used. Microducts save you time and money, allowing for economical growth within your communications network.

Micro duct is mainly made of high density polyethylene (HDPE) and manufactured by the technology of synchronized extrusion of PE. Its standard outer diameter is less than 16mm and its inner wall is permanently solid lubricant layer (silicon layer). Its construction has the following characteristics:

1. Two layers, inner and outer layer is manufactured by the technology of synchronized extrusion of PE in order to achieve the tight joint without separation.

2. Inner wall of duct has two kinds: smooth inner wall or the inner wall with longitudinal ribs to guide the airflow. No matter which kinds, both are permanently solid lubricant layer with very low friction of coefficient.

3. The duct surface is smooth without defects such as visible holes or scars..

The HDPE raw material used for the manufacture of micro duct has the following technical specifications:

Features and Benefits

Better way to utilize space in your duct or innerduct system

Installations are quick and easy

Classification and Structure of Micro Duct

The appearance of whole micro duct has solid color, Hawei can provide the full color spectrum to customers as required for choice.

In general, there are two typical sections of micro duct as follows: :

Picture 1:Micro duct with smooth inner wall Picture 2:Inner wall with longitudinal ribs to guide the airflow

The above two kinds of micro duct structures are to be defined based on the norm as follows:

Note: D Outer diameter of micro duct

d Wall thickness of micro duct; as for the inner wall of micro duct with longitudinal ribs to guide the airflow, the wall thickness of micro duct is defined at the central line of longitudinal rib, which is indicated by the above picture 3.
