COD Pipe Production is developed and made by Ruijin Machine Company in recently years and put the new production in the market at the first time, it has high output, simple craft, high autoimmunization degree, easy operation, etc, fill up the blank of china, has a high level in the market.
C.O.D is an English abbreviation about Corrugated Optic Duct of corrugation cable pipe. It summarize kinds of cable, light cable, canal on the basis of advantage and disadvantage, use the new concept to develop the new period high performance cable pipe. It adopt the lowest friction coefficient HDPE as main raw material, choose the lowest friction coefficient arris wall pipe as son pipe in the structure, resist-high pressure and willowy corrugation pipe as mother pipe, by complex extrusion forming. The main characteristic is resist-high pressure, can bend, can differentiate, convenience construction, it has others unable comparers advantages in physics performance, using time, project construction, etc.

Resist-Pressure
COD production is a special spiral shape, it increases traditional PE straight pipe resistpressure ability, the ability of resistpressure is more times than traditional pipe, improve validity and flexibility, it can also guarantee security when happened on earthquake or sink.
Resistchemical rot, wear strong and resistacid, resistalkali strongly, excellent resistwater, if lay on the sea or wet ground, it can resistrot, its a halfforever tube.
reliability
Because material has not electric and high insulation, it is a perfect cable pipe. In addition, heat expand and shrink of surface lower than traditional pipe system, and because inside and outside of primary material are the same, keep the same rate forever.
Because COD pipe twist on the frame of tube, so it can lighten a lot of labor costs, the most important is that COD neednt to cut in inner pipe, because kinds of inner pipe has already set up inside of outside pipe.
Because of light weight 0.95:1.43 , COD is very light, compare to traditional pipe, its very convenient to transport and construct.
spiral machining, COD is able to bend freely, it can reach to 90 if you bend it forcibly, even more angle, you need not to have any special tool for bending or pulling straight. And it can round when meets barrier on the construction location.
Due to inner pipe has excellent single line design and the lowest friction coefficient, no having joint, no having wrest ties problem, lead convenient, at the same time it prolongs the distance of hole. Inner pipe has already closed, it can resisthigh press, it can use light line gas pull method. Under the same outsidediameter, can more than inner pipe, increase the benefit of using.
The most important is, COD is leading mostly 75% of the diameter of inner tube diameters light cable; however, the most is leading 50% of traditional pipe.
