COD cable bundle tube production line .C.O.D corrugated cable conduit Corrugated Optic Duct English abbreviation. This is summed up in the past,Website:http://www.chinaextruders.net, a variety of cable, cable conduit advantages and disadvantages on the basis of a whole new concept developed by a new generation of high-performance fiber optic catheter. It uses a very low coefficient of friction modified HDPE as the main raw material, low coefficient of friction on the structure of the sub-pipe tube edge wall to high pressure, flexible bellows for the main pipe, the composite extrusion from. It high pressure, can be bent, a distinction, easy construction as the main features, with many other products can not match advantage in terms of physical performance, life, construction and the like.Features：1. Compression: COD product is a special spiral shape, which enhances the compression capabilities of traditional PE straight pipes, which under pressure is several times the traditional tube and improve the effectiveness and flexibility, earthquake, subsidence, etc., to ensure safety. Chemical resistance, durability strong acid, strong alkali capacity, better water resistance in sea water and wetlands laying, resistant to corrosion, is semi-permanent pipeline.2. Credibility: because the material is not conductive, high insulation, is ideal for cable ducts. Also the appearance of thermal expansion and contraction rather than conventional catheter system, and since the inner appearance as raw materials, and always maintain the same ratio.Because COD tubes (each 500 meters) coiled tube rack, it is possible to reduce the considerable labor costs, the most important thing is, COD not need to insert the tube, because the tube has a variety of equipment inside the outer tube.Because of the lighter gravity (0.95: 1.43), COD fairly light, and traditional tube than for the construction and transportation is very convenient.Since the thread processing, COD can be bent freely, bending
