Product Detail

Guizhou Yasu Tube Industry Co.,Ltd is one of the leading cod optic tube bundle manufacturers and suppliers in China, welcome to buy and wholesale cheap, fashion and customized hope tube bundle made in China from our factory.

 



A new generation of protection tube--- COD (corrugated optic duct), based on summarizing various advantages and disadvantages of traditional ducts, and arises at the historic moment. Known as the best protection tube, it takes polyethylene as raw material; in structure, it takes ribbed tube or silicore tube with low coefficient of friction as inner tube, and flexible corrugated tube with resistance to high pressure as the main tube, which is made by composite extrusion. Any protection tube can’t match its comprehensive performance. COD, with its excellent physical and chemical properties, perfect structure, low cost, convenient construction, and other advantages, has become the first choice of protection tubes under various terrain conditions. COD tube has the following advantages, such as strong practicability, excellent security, easily- distinguished inner tube, good pliability, simple installation, external pressure resistance, a variety of combinations of inner tubes and distortion resistance.

Unique Characteristics of COD, the Corrugated Optic Tube Bundle 

1?The corrugated shape of COD enhances its ring stiffness; and the unique composite structure of inner and outer tubes improves its property of load resistance.

 2?The corrugated shape of outer optic duct of COD can make it wind up to 1000 meters long, so that long and discontinuous installation becomes feasible.

 3?HDPE , as the material of corrugated duct and optic inner tube for COD, can resist various kinds of chemical erosion existing in the soil. They enjoy a long service life and can be buried underground for 50 years.

4?The optic tube of COD adopts blown cable technique to lay long-distance optical cables.

5?The optic tube of COD enjoys a high construction efficiency. Many tubes can be laid at a time to reduce the finishing process of fixed distance binding compared with silicore duct. Without protective galvanized steel tube while passing bridge or road, the cost of materials and construction is far lower than that of the same number of other ducts.

 6?The overall construction cost of COD is relatively lower than that of current products, and its convenient construction greatly shortens the construction period.

Unique Technique

COD, through unique annealing process, has been currently the most suitable tube used for optic cable protection. And the longitudinal retraction rate is only 1%, less than ordinary HDPE tube, so that it enjoys a longer service life.

Impact Resistance and Durability

The density of porous optic duct of COD reaches 955 kg/m3. Its hardness and durability are higher than that of similar products, enjoying a strong compressive property.

Extensive Range of Applicable Temperature

COD tube bundle can be used normally at 30? below zero outdoor without any damage. When the temperature is as high as 70 ? without external mechanical forces, it can still be used in safety. Even if the temperature fluctuations reached 80 ?, the tube line can still maintain the normal use within a short period of time.

Chemical resistance

Due to the alkane structure of the material, the porous optic duct of COD owns a very high chemical resistance.
