Hotspot: Analysis of Development Prospects of Green Pipe Industry

Abstract: With the development of science and technology, the quality of people's lives has been continuously improved and self-care awareness has been continuously enhanced. “Health” and “security” have become the two themes most concerned by modern people. Therefore, polyethylene, polypropylene, polybutylene, and aluminum-plastic composite pipes, which are called green pipes, are increasingly favored by modern urban people who pursue health and lifestyle.

In daily life, the quality of drinking water and the safety of water pipes are the focus of attention. Metal pipe has four fatal weaknesses: easy to rust, easy to corrode, easy to leak, easy to scale. After galvanized steel pipes are eroded, they will breed various microorganisms and pollute the tap water in the pipeline. The bacteria carried in these contaminated tap waters are like invisible killers and threaten people's health at all times. In the past 10 years, some developed countries have successively enacted legislation or established industry regulations prohibiting the use of galvanized steel pipes as drinking water transfer pipes, and proposed that the use of green pipes as the main body should be used without rust, corrosion, leakage or scaling. High quality pipe.

According to the experts on building materials, the green pipes produced in China mainly include polyethylene pipes (PE), polypropylene pipes (PP), polybutylene pipes (PB), and aluminum-plastic composite pipes (PAP). More than 80% of these pipes are used Building water supply and radiant heating. Compared with other plastic pipes, it is more suitable for indoor small-diameter water supply pipes, radiant heating and floor heating, and indoor low-pressure gas pipes. Before 1997, the use of aluminum-plastic pipes was relatively narrow, production was relatively small, and there were few sales in the market. However, since 1997, as the Ministry of Construction has restricted the use of galvanized pipes in new houses, the use of new green pipes such as polyethylene pipes, polypropylene pipes, polybutylene pipes, and aluminum-plastic composite pipes is recommended. As a result, the green pipe market is actively sold. Both production and sales are booming. Some varieties have already been in short supply, becoming a new growth point for the national economy and becoming a hot spot for investment. This laid a solid foundation for further maintaining the health of the "blood" of the home. According to market research, the output of these green pipes for two consecutive years from 2002 to 2003 has risen to more than 3 million tons and is expected to exceed 3.5 million tons this year.

According to market research, since 1997, due to the rising demand for these green pipe products, the benefits of producing the products are high, and local markets are swept up. As a result, the market is very unstable, and the quality, output, and prices fluctuate drastically. However, after several years of fierce market competition and industry consolidation, some small plants with poor equipment, small production lines, small production volumes, and low quality have already withdrawn from the market, and new competitors have few opportunities to enter. It is expected that the polyethylene pipe, polypropylene pipe, polybutene pipe, and aluminum-plastic composite pipe market will maintain a steady development trend in the next few years.

Pipe fittings are the main components of the oil and gas chemical industry, power industry, chemical industry, pharmaceuticals, boilers, heating, shipbuilding, and machinery manufacturing. Pipe fittings are used for turning pipes, reducing connections, rerouting, decompression, and other places. Pipe fittings were first used in the sewers. With the progress of society, they are now used in various fields according to different requirements, such as the pharmaceutical industry. Stainless steel is used for disinfection after processing; some pipeline fluids are corrosive, and corrosion resistant materials are required. To do pipe fittings; high-temperature high-pressure pipe fittings for the power industry, the use of alloy thick-walled pipe fittings and so on.

After more than 20 years of development, China's pipe fittings industry has reached a considerable scale and has maintained a rapid growth rate. At present, there are tens of thousands of domestic registered pipe fittings factories, and there are more than 300 in a certain scale, which can produce 160 categories and more than 10,000 varieties. Since the 1990s, the gross output value of China's heavy industry has maintained rapid growth. During this period, the total value of China's pipe fittings industry and the growth rate of market sales have been maintained at the level of 16-20%. According to the statistics of the Economic and Trade Commission on production enterprises, the average annual growth rate of the total industrial output value of pipe fittings industry at constant prices in the past two years is above 15%. The average annual growth rate of total profits is as high as 50%. The “Tenth Five-Year Plan” for heavy industry projects that by 2010 China's pipe fittings industry will have a total output value of RMB 1,000 billion, and the domestic pipe fittings industry market is very promising. It has been learned from the National Institute of Economic Research that China will invest hundreds of billions of yuan each year in chemical and electric power, and pipe fittings will account for more than 30% of it. At present, China's pipe fittings industrial production level is still very low, China also needs to introduce advanced equipment, scientific management, coupled with our unremitting efforts to produce high-quality pipe fittings. In foreign countries, especially in countries where petrochemicals are important, a large number of high-quality pipe fittings are required for the inspection and diversion of pipelines every year. Exports are also a bright road. The project will produce high-standard pipe fittings in a scaled manner, with a high passing rate of 100%, and will occupy the market in a way that gradually meets domestic demand and gradually exports.
