CHINA BAOLI HDPE silicon core pipe:

Introduction of CHINA BAOLI DUCT:

The Optical cable is very popular in the 21th century that go with the fast development of telecom industry. It is inevitable that strengthen the protection to optical cable. At present, BAOLI silicon core pipe is most advanced cable jacket material, good performance, low price, convenient to construction and durable, instead of multi-holes concrete pipes, PVC pipes and HDPE double side corrugated pipes step by step, become the perfect products in cable jacket material.

To catch up with the development of world telecom industry, our company researched and develop this product by our abundant technical strength and rich production experience through two years hard work.

The HDPE silicon core pipes' main characteristics are:

1. Adopt the mode of multi-machine co-extrusion, silicon core layer is synchronizely embedded in the pipe. It will be 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 tensioned in the pipe. Trough using cable blowing machine, one time blowing length can be 1000 to 2000 meter under normal conditions.

3. Good tightness, waterproof, damp-proof, can avoid the damage by rodent animals.

4. With great ring stiffness and toughness. In construction, its bending radius should not be less than 10 times of the external diameter of the pipe.

5. Aging-resistant, anticorrosion of chemicals. With long service life, and will not deteriorate within 50 years in the earth.

6. Good weather resistant ability, and its suitable temperature scope is from -40°C to 100°C.

7. Convenient in construction. This will save time and the project cost is only 30% of the PVC pipe.

Specifications and Colours of CHINA BAOLI HDPE silicon core pipe:

1. Specification of the Products

Our company provides customers with the following specifications of silicon core pipes or light pipe: Φ50/42, Φ48/40, Φ46/38, Φ40/33, Φ34/28, Φ32/26 and so on. We also can make products according to customers’ requirement.

2. Colors of the Pipes

Our company can produce many pure color silicon core pipes. Longitudinal color stripes of various colors can be enchased on certain pure color pipes. In this case, different pipes can be distinguished when laid in the same ditch. Such as 1×4, 2×3, 3×2, and so on.

3. Recommended specification and colors

To improve the antioxidation ability of the silicon core pipes and prolong its service life, we recommend black (substrate) silicon core pipes with longitudinal color stripes.

For the economy of the total project cost and to facilitate the loading and unloading, transportation and construction of products, and after verifying by the practice of customers from all areas, silicon core pipes with diameter of Φ40/33 and the length of each roll 2000m are the best one for design and construction. Of course, we can produce 500m, 1000m, 1500m, 3000m, and any lengths products according to customers requirements.

The Notify of Ordering of BAOLI HDPE silicon core pipe:

1. We have many specification silicon core pipes for customers’ selection.

2. Pipe Diameter:

Pipe diameter decided by the outer diameter of cables. Usually, the referring parameter according to the rate between inner diameter (ID) of silicon core pipes and outer diameter (OD) of cables, the parameter will be the best in the range 2—2.3, it will lay longer pipes when select blowing method. The common silicon core pipe is (OD/ID): 40/33, 50/42, 32/26. We can refer the following table for select appropriate pipes:

Blowing machines can connect silicon core pipe from OD 25mm to 63mm. The machine con not work if the OD exceed this range, but can adopt other method (such as traction method) to install cables.
