Plastic pipes will be used in drinking water delivery

For a long time, residential water supply mainly USES steel, iron galvanized pipe, because its inner wall is easy to rust, scale, breeding bacteria and microorganisms and other harmful impurities, so that tap water in the pipeline transportation caused "secondary pollution".In daily life, the quality of drinking water and the safety of water pipes are the focus of people's attention.Metal pipe has four fatal weaknesses: easy rust, easy corrosion, easy leakage, easy scaling.The corrosion of galvanized steel pipe will breed various microorganisms, contaminating the tap water in the pipeline.The bacteria in the polluted tap water are like invisible killers, always threatening people's health.In the past 10 years, some developed countries have legislated or established industrial rules and regulations to prohibit the use of galvanized steel pipes as drinking water delivery pipes, and put forward the comprehensive use of green pipes as the main body of no rust, no corrosion, no leakage, no scaling of high-quality pipes.

Recently, during the "twelfth five-year plan" two sessions, the NPC deputies also put forward the "comprehensive promotion of new energy-saving green pipe, promote energy conservation and emission reduction and circular economy development" Suggestions."Prohibit the use of cold galvanized steel pipe and all kinds of composite cast iron water supply pipe, limit the use of hot galvanized pipe, promote the use of all kinds of new plastic pipe and plastic composite pipe and other green pipe imperative.It is reported that some people suggest that the relevant departments of the state financial subsidies and a series of policies and measures to comprehensively promote the new energy-saving green pipe similar to HDPE.

According to the introduction of experts on building materials, China's production of green pipe mainly polyethylene pipe (PE), polypropylene pipe (PP), polybutene pipe (PB) and aluminum composite pipe (PAP), these pipes more than 80% used for building water supply and radiation heating.Compared with other plastic pipes, it is more suitable for indoor small-diameter water supply pipes, radiant heating and floor heating, indoor low-pressure gas pipes and so on.

According to the market survey, after 1997, due to the rising demand for green pipes in the market, the local rush, once led to a very unstable market, quality, output and price fluctuations, market competition is very fierce.To this, luo baihui, secretary general of the international mold and plastic industry suppliers association, said, at present, China's plastic pipe market economy is more intense, more than 3,000 large-scale plastic pipe production enterprises, annual production capacity of more than 15 million tons, annual capacity of more than 10,000 tons of enterprises reached 300, there are more than 20 annual capacity of more than 100,000 tons.

But after several years of fierce market competition and industry integration, some equipment level is poor, production line is small, output is small, low quality small factory has withdrawn from the market, new competitors and few opportunities to enter.It is expected that the green plastic pipe market, such as polyethylene pipe, polypropylene pipe, polybutene pipe and aluminum-plastic composite pipe, will maintain a steady development in the next few years.

With the development of science and technology, people's quality of life is constantly improved, and their awareness of self-care is also constantly enhanced. "health" and "safety" have become the two major themes that modern people pay the most attention to.And environmental protection plastic pipe water supply pipe and galvanized steel pipe, because of harmless to the human body, corrosion resistance, thermal conductivity of small advantages, and more and more by the pursuit of health and fashion life of the modern urbanite's favor.Green plastic pipe market will continue to grow steadily in the future.
