Ho-Pipe Co., Ltd., Zhengzhou (www.zzhtgy.com) is located in Zhengzhou City, Henan Shenzhou No. 168-2 Avenue, Contact: Zhang Kuaiyong Zhengzhou Haotong Pipe Co., Ltd., is the Central Plains municipal drains relatively large double-wall corrugated HDPE One pipe manufacturer Features: the inner wall of the silicon core is solid, permanent lubricant; their inner wall of the silicon core is synchronized squeezed into high-density polyethylene pipe wall, and evenly distributed throughout the pipe wall will not peel off, from the same silicon tube life; silicon core layer and the inner wall of high density polyethylene having the same physical and mechanical properties; wall friction characteristics of the silicon core layer remains unchanged, the cable may be in the pipeline Repeated extraction; the inner wall of the silicon core layer does not react with water, washed with water pipes after an accident. Zhengzhou, Henan Haotong Pipe Co., Ltd., is a large Central Plains Municipal sewer HDPE double wall corrugated pipe production, one double-wall corrugated pipe used in all aspects of life pvc pipe, or in China in recent years to do. Pvc water supply parameters in the telecommunications, railway pvc pipes to custom, in the central air-conditioning duct systems, sewage treatment systems, double-wall corrugated pipe pipe in all walks of life. But in Europe, the amount of double-wall corrugated pipe is still very large. According to the European 97-year investigation, the total amount of 2.264 million tons of plastic pipe used for drainage and sewerage is 1.274 million tons, accounting for 56.2%, this is because the country needs to build a modern, large sewage pipes throughout rural and urban drainage systems. In terms of the use of pvc pipe to pipe pictures, because technically more advanced European countries prefer the double-wall corrugated pipe. Its light texture, cold resistant, more suitable for the use of sewage treatment systems.
