Carbon tube Features: The unique product architecture, compression and strong, smooth wall, over flow, Rao has a good song performance, can be adapted to the soil uneven ups and downs, long life, geography can be used for more than 50 years. Point of view, their life and fatigue characteristics of the chosen material to a great relationship, but also on the quality of the bellows and affordability conditions, under different operating conditions, such as work in which temperature, vibration condition , displacement, pressure and other factors, to the bellows of life will change. Under standard operating conditions, the service life can be achieved basically about 50,000 times, it can choose to allow displacement of carbon between 10-40% of the effective length of the bellows tube compared to traditional cement pipe advantage bellows: good strength and stiffness, belong to the flexible tube, under the correct design and construction conditions, fully meet the burying of resistance to external load requirements; excellent hydraulic characteristics, smooth wall, small resistance, the same diameter and the design slope. Traffic transmission capacity than the concrete pipe; seal socket connection, flexible interface, anti-settling, sealing, no leakage, no environmental pollution; corrosion, abrasion resistance, anti-aging, anti-cracking, long life, more than 50 years; light weight, no special lifting facilities, handling very easy to install; integrated better economy. Carbon tube construction method and related knowledge: 1, carbon diameter selected according to the cable diameter, the allowable voltage, current, and other conditions of project selection. 2, trench digging engineering and user requirements in accordance with relevant provisions of trenching, its width and depth should be based on the laying of cables may be. The distance between the pipe and the trench is 50mm, the distance between the tube and the tube is 30mm. 3, the laying of the carbon tube into the ditch, where the curvature of the wound or to prevent extrusion, have to use cement potting. In two jacket pipe connecting the mouth shall brick and cement sheath tube head is fixed. 4, need to connect two carbon tube butt joints screwed to one end of the first to be taken over, then spin down to the end of another takeover, with PVC sealing tape can be wrapped. 5, according to the requirements of the carbon tube backfill After laying, trenching to backfilling with the original soil when and backfill compaction. Carbon tube is a high-density polyethylene and a modified carbon as the main raw material, carbon tube using the new power cable protection pipes extrusion and unique rotational molding technology production.
