Since 2000, China's plastic pipe production ranks second in the world. In 2008, China's total output of plastic pipes reached 4.593 million tons. In the past ten years, the plastic pipe industry in China has developed rapidly. The output has increased from 200,000 tons in 1990 to nearly 800,000 tons in 2000, and has maintained an annual growth rate of about 15%.

The downstream applications of HDPE plastic materials mainly include outdoor water supply pipes, buried drainage pipes, jacket pipes, building water supply and drainage pipes, etc. Most of these downstream applications are directly or indirectly related to the real estate industry. Data were selected in the year 2000-2008 In the analysis, we found that there is a strong positive correlation between the plastic pipe industry and the real estate completed area.

平均 The average growth rate of PPR and PE plastic pipes in the future will be higher than that of the pipe industry: At present, most of the international plastic pipes of various materials and structures have been produced and applied in China. In the early days, there were many PVC plastic pipes in China. They were mainly used for electric wire pipes and sewage pipes. However, PVC pipes have certain shortcomings in terms of frost resistance, heat resistance, and strength. The market growth rate will be lower than that of new plastic pipes (including PPR). , PE, PB, etc.), the growth rate of new plastic pipe industry has exceeded 20%, which has become the development direction of China's plastic pipe.
