Qingdao Jia Sen presses perennial production PE carbon spiral crew, PE carbon spiral pipe the unit configuration polyolefin dedicated single-screw extruder, with high-speed extrusion, high-speed plasticization. The best design of the low melting temperature, the internal stress of the pipe, smooth inner and outer surfaces. High flexibility, suitable for all co-extrusion of polyolefin materials, the use of layers of different specifications can be extruded spiral reinforced pipe. Can be used for more than 80% of recycled material. The sizing sleeve optimize the design of the copper spiral entrance carrying pre-cooling device and powerful vacuum suction device suitable for high-speed extrusion of the pipe. Dedicated Separation mixing screw and spiral structure of the nose, reasonable channel, smooth inside the pipes. Specially designed sizing and cooling mode: production range of 50-200mm, production speed of up to 0.6-1.5 m / min. PE carbon spiral units PE carbon spiral power communications Buried sleeve superior grade HDPE material, adding carbon, PE modified masterbatch extruded from the buried city power communication line construction pipe. Because of its the smooth inner spiral structure; tube with flat walls, the direct friction coefficient with flat-wall tube compared to a decrease of 60% compared to reduce friction wire fiber optic cable. Spiral wire and fiber optic cable because of its unique inner wall provides good ventilation space, wire and fiber optic cable to effectively extend the service life, reduce maintenance costs, power communication department operating costs. PE Carbon Spiral power communications buried casing with high impact toughness, resistance to corrosion, seismic performance advantages, the surface subsidence change adaptation capacity is very strong. The products inside and outside the single-walled helical structure, convenient to use a reel processes, increase the effective pipe length of up to 50m-200m; its internal plus put a pull wire conductors can be provided for the construction conditions. The pipe according to the diameter of the 50m-200m-site inspection is no joint construction. To ensure that the pipes do not leak, the protection of wire cable security and reduce construction costs. PE carbon spiral power communication buried casing, to solve the city overhead complicated, dangerous operation and maintenance costs have long plagued powered communications sector problems. PE carbon spiral power communication buried casing is the ideal environment-friendly, safe products
