Residential development in China has now entered a new phase, a continuous growth in real estate development and investment, "during" each year new construction in urban and rural area of about one billion square meters, respectively. With urbanization, the rapid development of small cities and towns, in 2004 reached the level of urbanization in China has reached 41.8%, in the take-off phase, is expected to reach 47% in 2010, this period will last 30 - 40 years. Speed up the urbanization process will lead the development of urban infrastructure construction, plastic pipes for various purposes is essential materials. Plastic drainage pipes and sewage treatment will continue to maintain relatively high growth rate Plan 2010 of reclaimed water in the water to reach 30% of the total water needs specialized laying pipelines, building also need to increase wastewater reuse in the water distribution network design. Many opportunities will greatly promote the further promotion of plastic pipe applications. Agricultural pipe is a large market of plastic pipe The end of 2004 there are 322 million rural people are drinking unsafe condition, accounting for 34.3% of the rural population. 63.5% of water supply project for the distributed, centralized water supply is also relatively small proportion. National planning by 2020 to basically solve the drinking water safety in rural areas, this is the most successful application of plastic pipe in the field. 2005 survey showed that 96% of the villages have not drainage and sewage treatment systems. In recent years a large number of water-saving irrigation area will increase, and the future sewage treatment in rural areas have a large market, merit attention. Transformation of urban water supply network to speed up the pace According to estimates of the "Eleventh Five-Year" period, the urban water supply pipeline length of about 20,000 km / year; city drainage pipeline laying length of about 15 000 km / years. In addition, our municipal utility pipes are running, the city of about 130,000 km of water supply pipe is laid before the 20th century, 80s, and now to the useful life, need to update and repair. February 2006 "issued by the National Urban Water Reform term planning (2006 -2,007)," and proposed to speed up the pace of transformation of water supply network in 2007, before the completion of transformation of urban water supply network planning project of 314 new , under construction total 16796km. Pipe network transformation to replace the pipe and increase the diameter of the main size of the project total 12628km. The total investment totaled 18.72 billion yuan. And would require active promotion of new pipe and new construction technology, and actively uses the high quality pipe and fittings. The program is also part of the city a total of 84 000 km pipeline network was incomplete, the current water supply network pipes used mainly gray cast iron, ductile iron pipes and cement pipes, etc., and plastic pipe 4467 kilometers, accounting for only 5.2 %, there is great market space. Accelerate the pace of active development of new fields According to the "on strengthening the technological innovation of chemical building materials industry of the number of views" and "national chemical building material industry," 15 "Plan and Development Plan 2010," the spirit of the proposal the "Eleventh Five-Year" period, the main products of plastic pipe industry to meet market needs, product variety, quality, and matching grade levels have significantly improved the overall level of industry reach or approach international advanced level; promote the use of plastic pipe shall meet the following objectives: By 2010, various types of plastic pipe in the national pipeline in more than 60% market share, including: building water supply and construction 80% of plastic sewer pipe, storm sewer construction 70% of plastic pipes, building wire jacket pipe threading 90% of plastic pipe, 70% of urban water supply pipeline plastic tube, 50% of urban drainage pipeline plastic tube, 60% of urban gas pipelines with plastic pipes. According to the status of plastic piping industry, proposed the "Eleventh Five-Year" during the processing industry will be to plastic pipe PVC-U pipes and PE pipes for the focus of development and to develop modified, composite and other new plastic pipes. Complete applications as soon as the matching and quality assurance system. Steady increase in the municipal, construction, water conservancy and other applications subject to, and actively explore plastic pipe in agriculture, non-excavation technology, old pipeline repair, mining, oil and industrial needs to vigorously develop new areas of applications. |
