HDPE Corrugated Optic Duct

HDPECorrugated Optic Duct 1.have passed the ISO 9001 2000 2.CE certificate 3.short delievery time. 4.better service

HDPE Corrugated Optic Duct 1)spiral/corrugated 2)co-extrusion form 3)3-9 sub duct 4)machine and products make/sell

C.O.D Corrugated Optic Duct  It uses friction coefficient extremely low modified HDPE is the primary data, in the structure take the friction coefficient extremely low long 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

 

Optiroad C.O.D. opens new era of telecommunication backbone with its built-in multiple inner ducts (3 to 5) inside of the outer duct by means of assembling cable ducts in the course of production. Both inner and outer ducts are m.ade of HDPE (High Density Polyethylene) having high flexibility enabling rolled-on spool regardless of numbers of inner ducts built-in.
