Development of PPR pipes
Compared with traditional cast iron pipe, galvanized steel pipe and cement pipe, PPR pipe has the advantages of energy saving, environmental protection, light weight, high strength, corrosion resistance, smooth inner wall, no scaling, simple construction and maintenance, long service life, etc. it is widely used in building water supply and drainage, urban and rural water supply and drainage, urban gas, electric power and optical cable sheath, industrial fluid transmission, agricultural irrigation, etc Political, industrial and agricultural sectors.
In recent years, with the increasing market demand of construction industry, municipal engineering, water conservancy engineering, agriculture and industry, China's PPR pipe industry presents a rapid development trend. In 2009, the production of plastic pipes was 5.804 million tons, with a year-on-year increase of 18.9%. From January to September 2010, the production of plastic pipes was 5.528 million tons, with a year-on-year increase of 28.23%. At the same time, with the continuous improvement of consumers' requirements for environmental protection, health, durability and other aspects of product quality, the output of plastic pipes in China is increasing, the product quality level is improving, the technological progress of the industry is accelerating, the brand scale enterprises are increasing, new materials and new structure varieties are emerging, advanced system design concepts emerge in endlessly, and the functionality of products is becoming more and more functional The application field has been further widened. According to the analysis, the market share of China's plastic pipes has exceeded 30% of all pipes in 2013.
By 2015, 85% of the building drainage pipes, 80% of the building rainwater drainage pipes, 50% of the urban drainage pipes, 85% of the building water supply, hot water supply and heating pipes, 80% of the urban water supply pipes (below dn400mm) and 90% of the rural water supply pipes will be plastic pipes, respectively 40% of the gas plastic pipes (medium and low pressure pipes) are used, and 90% of the building wire bushing is made of plastic pipes. It is predicted that during the 12th Five Year Plan period, China's plastic pipe production will maintain a growth rate of about 10%. By 2015, it is expected that the national plastic pipe production will be close to 12 million tons, and the market share of plastic pipes in all kinds of pipes in the country will exceed 60%.
