Either this year or in previous years, the news about the flooding emerge in endlessly, the latest on September 13, 2013 in the evening, hangzhou suffered heavy rains, the rain is not only bring traffic congestion, and grilled for urban drainage system, since July this year, prime minister li keqiang three speech mentioned "underground pipeline construction, the underground pipe network transformation and the construction as the urban infrastructure construction during the period of" twelfth five-year "key, and plastic pipe in various application fields needs huge space, the future growth.
Municipal and building water supply and drainage is still the main downstream pipe industry, with large-scale project construction, rural industrial water-saving irrigation, and the promotion of safe drinking water project, plastic tubing products in the field of industrial and agricultural applications will be further expanded. We expect the 13 to 15 years of plastic pipes in line with the growth of overall demand will reach 18%, growth fell back from 7 to 10 years, but still maintained rapid growth. Points structure, municipal water supply pipeline, municipal drainage pipeline and building demand growth will reach 24.73%, 24.73%, 21.44% respectively, is the fastest demand growth in the three segmentation industry industry.
Pipeline capacity to ascend, the domestic special material supply face challenges. China's pipeline industry concentration ratio is low capacity, facing integration. Plastic pipe production of 8.4 million tons in 2010, a total capacity of up to more than 1700, ten thousand tons of capacity utilization rate of less than 50%. PE pipe high degree of dependence on imports, domestic progress is slow. The special resin PE80 pipes and PE100 imports about 80% of high-end products.
Underground pipe network problems, "top-down" reform policies to be introduced. Lack of information sharing and data become underground pipe network construction problems. Line planning, construction and management points belong to the three government departments, segmentation for three parts, pipeline life cycle information is difficult to fully Shared. Pipeline attribute data is incomplete, lack of height, buried depth and other attribute information. Problems such as frequent as urban waterlogging deepening, top-down policy is expected to be a sequence of complex relationships, offset debt for the acceleration of the underground pipe network construction and pave the way.
Give priority to with PE pipe in the future promotion. Has declined each year proportion of domestic PVC pipe, PE pipe instead. Europe and the United States developed countries accounts for PVC and PE pipes than has been fairly, 46%, 43% respectively. PE pipe instead of PVC the trend of The Times. "Twelfth five-year" goal made it clear that by 2015 the application of plastic pipe are mainly composed of PE pipe, and develop the new type of plastic tubing.
