The company produces reinforced HDPE hollow wall winding pipe is made of high density polyethylene as raw material by hot extrusion winding forming new pipe. In addition to its high resistance to corrosion ordinary plastic pipe has good, high insulation, wall smooth, small flow resistance characteristics, it also uses a special hollow because "workers" shaped structure, with excellent ring stiffness and good strength and toughness, and light weight, high impact resistance, not damaged and so on. Products by GB / T 19472.2-2004 "Buried polyethylene (PE) structure wall pipeline system" requirements for production; The company mainly produces ring stiffness SN4, SN8, N12.5 grades, and according to customer requirements ; product color is black, but also by the two sides agreed to supply and demand; the inner diameter of the pipe DN200-DN1800; pipe length is generally 8m, up to 12m, but also by the supply and demand sides agreed. Features 1. Excellent chemical resistance: resistance to common organic solvents and acid corrosion, is not generally sewage, wastewater chemical corrosion, not because of soil organic matter decay and corrosion. 2. High impact resistance: HDPE plastic is flexible material, the elongation at break of up to 350%, and the pipe wall body with "work" type special structure, impact resistance, strong external pressure performance, the foundation does not appear slight Settlement of the situation is not even broken, and after deformation resilience and strong, has a good foundation for any adaptation. 3. Good weather resistance: pipe is usually black, which can effectively absorb the sun's ultraviolet rays, can withstand storage and construction process of the brunt of the sun. 4. Excellent temperature adaptability: Pipes at 40 ℃ -60 ℃ environment can be normal operations. Construction by the seasons, the temperature is less constrained, it will not be frost crack and shrink tubing leak at -60 ℃ environment. 5. Light weight: easy to transport, construction convenient, is 1/8 the weight of concrete pipes, large-scale machinery equipment than the small cement pipes required for the construction. 6. Easy connection: pipe can be connected in a ditch outside, with a backhoe pushed to the ditch. When urban drainage construction, can reduce the amount of engineering time and engineering costs. 7. drain liquidity and superior abrasion resistance: smooth wall, low friction, fast drainage, water and strong performance, can be replaced with a smaller diameter large diameter concrete pipe. 8. Economy: material price, low construction, management and maintenance costs. 9. Environmental impact: HDPE is non-toxic material, harmless to land, and the use of renewable energy entirely. Underground sewage, rainwater pipes, living area sewage drainage pipe products Applications 1. municipal building. 2. The sewage treatment system pipes. Farmland, orchards 3. in agriculture, forest irrigation water distribution network, delivery of agricultural water use. 4. Industrial wastewater treatment, discharge pipes, pipe manholes and chemical containers overall processing. 5. mine, drainage, ventilation ducts of the building.
