Introduction:
C.O.D is the Corrugated Optic Duct pipes English abbreviation. This was in summarized formerly each kind of fiber optics, advantages in the cable guide foundation, became the new generation high performance fiber optics drive pipe by the brand-new idea development. It uses friction coefficient extremely low modified HDPE is the primary data, in the structure take the friction coefficient extremely low leng wall tube as the sub-tube, bears the high pressure, the easy curving corrugated pipe is the female tube, after compound squeezes out becomes. It bears the high pressure, but is curving, has the discrimination, the easy construction is the main feature, in the physical property, the service life, aspects and so on project construction has the superiority which other many products are unable to compare.
Advantage:
1.The inner pipes are sticked into the inside wall of outer pipe.
2.The inner pipes are smooth ,it can work more expediently.
3.The special screw type of the outer pipe can have high ring stiffness.
4.High strong impact resistance,can be more better working under the sea.
5.The length of every volumn can reach to more than 1000 meters,so it can greatly improve efficiency of construction.
