hdpe silicone core duct 40/33,hdpe silicone pipe manufactuer,communication project silicon core pipe:

1.Material : HDPE silicon core pipe is a new type of composite pipe with silicon solid lubricant in inner layer, which be widely used in optical communication network system of highway ,railway etc, the main material is High Density Polyethylene

Features

2.Feature:

1) Good sealing properties, chemical resistance, low construction cost

2) Protects and guides cable, instead of steel tube and cement tube
3) Strong, corrosion-resistant, high-temperature resistant
4) No need for cement protecting, low cost.

5)The inner layer silicon core is solid and permanent lubricant

6) The inner layer silicon core is being co-extrusion pressed into high-density polyethylene pipe , and evenly distributed throughout the pipe wall, not shed off, same lifespan with silicon tube

7) The inner layer silicon core and high-density polyethylene pipe have the same physical and mechanical properties;

8)The inner layer silicon core keeps the same friction characteristic,Cable in the pipe can be repeatedly extracted;

9) The inner layer silicon core does not react with water, can rinse with water after accident

Applications

3. Applications:

1). Widely used in highway, railway and other optical cable communication network system ;

2). Widely used in Outdoor communication cable,public

information network , public transport system,cable TV network, freeway communication,Cable pipe system

3) Telecommunication, Computer Network, Automatic Signaling, Railways Information Network, Highways, Cable Service providers, Broad Band networks, Electric cable installation etc.

Advantages

4.Advantages:

1). Adopt multi-machine co-extrusion, the silicon core layer is synchronously embedded in the pipe. It will be permanent lubricated and not be stripped forever

2). The friction coefficient of the inner wall is very small. Optical cable (electric cable) can be repeatedly extracted and tension in the pipe.

3). Waterproof, damp-proof, can avoid the damage by rodent animals.

4). Aging-resistant, anti corrosion of chemicals, long service with 50 years

5). Good weather resistant ability, and its suitable temperature from -40°C to 100°C.

6). Convenient in construction, save time and the project cost
