subject: Plastic Pipe Industry Over The Next Decade, Faced With Tremendous Opportunities For Development [print this page] Plastic pipe is a new material, its markets, not only with the national economic development and growth, but also an alternative to traditional materials due to the additional growth, the pace of development of plastic pipe at home and abroad have exceeded the national growth rate of the national economy is expected in the next 10 years, there will grow rapidly. China plastic pipe industry, faced with tremendous opportunities for development is based on the industrial base has been established, market demand has noticeably increased, technological progress is constantly advancing. In the next five years, is expected to average annual total of China's plastic tube growth rate of 20% by 2005 will reach 1.6 million tons.
China is a serious shortage of water resources in the country, environmental pollution and makes the problem even more acute. With the improvement of people's living standards, China's per capita water consumption gradually increased, while the rural population to cities and towns in the gradual transfer of water supply projects throughout the infrastructure has become a hot spot.
Experts predict that China's urban water supply areas, "15" during the urban water supply will invest about 86 billion yuan to the city's annual water volume in 2005 will reach 57 billion m3, 1998 years of 40.7 billion m3 increase of 40%. By 2015, urban water supply will reach annual 70 billion m3, urban water population to 4.4 million people.
Water supply network in the past mainly in cast iron pipe, steel pipe and concrete pipe.
In recent years, the government's efforts to promote the use of plastic pipe in China has become the consensus. Under the "national chemical building material industry," Tenth Five-Year "plan and the 2010 Development Plan", 2005 National 50% of new urban water supply pipes plastic pipes, water pipes 60% of the villages and towns plastic tube; 2010 long-term development objectives are: Urban water supply pipe plastic pipe application rate of 70%, 80% of village water supply pipes with plastic pipes.
PVC and polyethylene pipe compared to the
For various reasons, in the past China's urban water supply network in the application of plastic pipes are mainly PVC pipe and polyethylene pipe application of relatively late relatively small.
Plastic pipe in the PVC pipe used for water distribution network, the oldest and, at present all over the world are still widely used. This is because the PVC pipe has a higher strength, rigidity and relatively low prices of larger and material advantages, and have extensive experience. PVC pipe fittings in China has developed rapidly in recent years, has established a number of million-ton modern enterprise, through the introduction of foreign advanced technology and equipment and management experience, China has been able to provide quality and reliable water supply network, supporting a more complete The Water Supply pipe fittings, Shanghai, Guangzhou and other cities in this area have accumulated much experience in the future water supply pipe with PVC pipe fittings still have great development.
It is noteworthy that, according to the world of experience and development practice in recent years, the past 10 years, the international development of polyethylene pipe faster than PVC pipe, in many areas, used for a number of water distribution network of polyethylene pipes more than PVC pipe.
