"China PPR pipe industry production and sales demand and investment forecast analysis report" pointed out that by 2015, in the country's new construction, reconstruction, and expansion projects, 85% of construction drainage pipes will be plastic pipes, 80% of construction rainwater drainage pipes will be plastic pipes, urban drainage The amount of plastic pipes used in pipes reaches 50%, 85% of building water, hot water supply and heating pipes are plastic pipes, 80% of urban water supply pipes (DN400mm) are plastic pipes, 90% of village water supply pipes are plastic pipes, and urban gas plastic The application amount of pipes (medium and low voltage pipes) has reached 40%, and 90% of construction wire threading protective sleeves are plastic pipes.
It is predicted that during the 12th Five-Year Plan period, China's plastic pipeline production will maintain a growth rate of about 10%. By 2015, it is expected that the national plastic pipeline production will be close to 12 million tons, and the market share of plastic pipelines in various types of pipelines in the country will exceed 60%.
PPR pipe is officially called random copolymer polypropylene pipe, which is the most widely used water supply pipe in home improvement projects. The quality control problem of PPR pipe raw materials. PPR is a random copolymerized polypropylene synthesized by the gas phase method (PP and PE). Its structural feature is that the PE molecules are randomly linked in the PP molecules, and the molecular weight ranges from 300,000 to 800,000. . Pipes produced from PPR raw materials are also called random copolymer polypropylene pipes, which are plastic pipe products developed and applied in the late 1980s and early 1990s.
With its own excellent performance and a wide range of applications, it has occupied a place in the plastic pipe market and is recognized as a green product. However, the market operation in recent years, the above examples of PPR plastic pipe quality problem analysis examples also found that many problems have occurred in the PPR pipe market, these problems have largely restricted the healthy development of PPR pipes.
