Detail Information

Fabric Innerduct Overview 

Fabric Innerduct is the only flexible fabric innerduct system designed specifically for the network construction industry. The unique fabric 

construction greatly reducing the wasted space associated with rigid innerduct.

Inflatable type culvert sealing system, which have been widely used in the design of underground culvert constructions in the industries 

of electric system, telecommunications, port, urban construction, rail transportation and so on. Provide a clean and dry operating 

environment to cables and other electrical equipment after installation, improve the degree of protection, and reduce the works of 

cleaning up sludge and stagnant water in the manual well before the maintenance works.


1.Light construction

The textile sub-tube has no bending memory; it does not curl like a PE sub-tube;

The textile sub-tube will not be kinked during laying and can be bent freely during laying;

The textile sub-tube is preset with high-strength draw tape in each hole, and the laying of the cable does not need to be through-hole, 

and the laying is more convenient and quick;

The construction site requirements are very small, especially suitable for busy districts;

2.Protection cable and outer tube

The breaking strength is above 1000 kg;

Textile tube melting point = 215 ° C, while HDPE sub-tube = 110 ° C;

The thermal expansion and contraction rate of the textile tube is 1/7 of that of the HDPE sub-tube;Prevents wear between cables;

3.long lasting

The textile sub-tube has high chemical inertness and can be exposed to a harsh underground environment for a long time. The design life

 is 30-50 years, and the life of the PE sub-tube is only 15 years;

4.Resolution recognition design

Two holes in the textile sub-tube product family, three holes will be preset with different colors of the draw tape for the differentiation

during construction;

The textile sub-tube will print the meter mark when it leaves the factory to prevent unnecessary waste during construction;

When the textile sub-tube is delivered from the factory, it will be labeled according to the customer's needs, such as A, B, C A1, A2, A3, etc.,

used to distinguish the multiple textile sub-tubes in the pipeline, to facilitate the maintenance of the line;

5.Environmentally friendly design concept

The textile sub-tube can reach 30-50 years underground. Ordinary HDPE sub-tubes will form slag due to aging in the ground for a long 

time, and become a blockage in the pipeline. The textile sub-tube solves this problem from the design concept and has high environmental 

protection for the pipeline.
