cod pipe and machine
COD pipe and machine 1)corrugated/spiral shape 2)co-extrusion forming 3)3-9 inner ducts 4) low price high quality
COD pipe and machine
COD pipe 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 discriminati on, the easy construction is the main feature, in the physical property, the service life, aspects and so on project construction has the superiority
Coiling Length of C.O.D.each reel may practically coiled up to 500 meters, however, coiling even 1,000 meters of small dimension model is also available.
flexible and lengthy product of COD, it enables quick installation reducing considerable consecutive work quantities such as trench excavation, inner duct insertion
