Plastic pipe will give huge prospects to the building materials market

China's plastic pipe has developed into an important category of plastic products. Chemical building materials are the fourth largest category of new building materials emerging after steel, wood and cement. Plastic pipes, plastic profiles, doors and windows are the two main varieties used in chemical building materials. Since 1994, the Chinese government has jointly organized and organized the "National Chemical Building Coordination Coordination Leading Group" by the Ministry of Construction, the former Ministry of Chemical Industry, the former China Light Industry Association, the State Building Materials Bureau, and the former five Sinopec headquarters. In the short period of several years, China's plastic pipe, profile, doors and windows have achieved rapid development. The production capacity of plastic pipes in China was 240,000 tons in 1994 and the output was 150,000. Ton, capacity was 1.64 million tons in 2000, output was 1 million tons (of which PVC-U pipe production was about 500,000 tons), pipe production lines had reached more than 2,000 pieces, hard PVC pipes were produced at scales above 10,000 tons There are more than 30 companies in the country.

The traditional pipe network mainly consists of steel pipe, cast iron pipe, cement pipe and clay pipe. Traditional pipe materials generally have the characteristics of high energy consumption and easy generation of environmental pollution. At the same time, the pipe network also has the following shortcomings: 1 The service life is short, generally 5-10 years; 2 poor resistance to chemical corrosion resistance; 3 poor hydraulic performance; 4 high construction costs, long cycle; 5 poor integrity of the pipeline, easy to leak and so on. Since the middle of the 20th century, all countries in the world, especially the developed countries, have been developing special materials for plastic pipe and the use of plastic pipes.

In the past decade, plastic pipes have developed rapidly. Plastic pipes are increasingly favored for their environmental protection and safety in life and industrial applications and play an important and irreplaceable role. Especially in the construction industry, plastic pipes can not only produce large amounts of steel, substitute wood, and replace traditional building materials, but also have the advantages of energy saving, material saving, ecological protection, improvement of living environment, improvement of building functions and quality, reduction of building weight, and ease of construction. It is widely used in the fields of building water supply and drainage, urban water supply and drainage, and gas pipes; the growth rate of plastic pipes is about four times the average growth rate of pipes, which is far higher than the growth rate of the national economy of various countries. Replacing cast iron pipes and galvanized steel pipes with environment-friendly green plastic pipes has become a trend of development in the new century. Plastic tubing has been successfully developed and widely used in developed countries, especially in Europe; its development in China has lagged behind, but in recent years, as China’s overall national strength has increased and people’s living standards have improved, plastic pipes have seen rapid progress. development of.

The varieties and applications of plastic pipes have developed rapidly in the past few years. At present, China's plastic pipe has developed into a building material industry with complete varieties and relatively large production capacity. The main varieties of plastic pipes include UPVC pipe, CPVC pipe, and PE pipe. , PAP pipe, PE-X pipe, PP-B pipe, PP-R pipe, PB pipe, ABS pipe, steel-plastic composite pipe, glass fiber reinforced pipe and so on. Widely used in construction water supply pipes, drainage pipes, urban buried water supply pipes, drainage pipes, gas pipes, rural water supply and drainage pipes, irrigation pipes, as well as industrial sewage discharge wastewater and chemical fluids, etc. The different needs of the pipe. We should develop and produce a certain type of plastic pipe according to the characteristics and applications of various pipes.
