COD cable protection sleeve pipe extrusion machine was the JBD machinery independently develops the development in recent years, and in domestic took the lead the new product which promoted, had the output to be high, the craft was simple, the automaticity was high, characteristics and so on ease of operation, have filled the domestic gap, was in the domestic advanced standard. The changjie brand COD pipe production line output velocity reaches as high as 1.5m/min, each end product length may amount to 500 meters. The processing technology has surpassed the world advanced level!

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.
