Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, PPR pipes have the advantages of energy saving, environmental protection, light weight and high strength, corrosion resistance, smooth inner wall without scaling, easy construction and maintenance, and long service life. They are widely used in construction, municipal, industrial and agricultural fields such as building water supply and drainage, urban and rural water supply and drainage, urban gas, electricity and optical cable sheathing, industrial fluid transportation, agricultural irrigation, etc.
With the increasing market demand in construction, municipal engineering, water conservancy engineering, agriculture and industry, China's PPR pipe industry has shown rapid development. In 2009, the production volume of plastic pipes was 5.804 million tons, a year-on-year increase of 18.9%. From January to September 2010, the production volume of plastic pipes was 5.528 million tons, a year-on-year increase of 28.23%. At the same time, as consumers' quality requirements for product environmental protection, health, and durability continue to increase, while the output of plastic pipes in my country continues to increase, product quality levels continue to improve, technological progress in the industry continues to accelerate, brand-scale enterprises continue to increase, new materials and new structural varieties continue to emerge, advanced system design concepts emerge in an endless stream, product functionality becomes more obvious, and application fields are further broadened. Analysts believe that China's plastic pipe market share has exceeded 30% of all pipes.
By 2015, in new construction, reconstruction, and expansion projects across the country, 85% of building drainage pipes will use plastic pipes, 80% of building rainwater drainage pipes will use plastic pipes, the use of plastic pipes in urban drainage pipes will reach 50%, and 85% of building water supply, hot water supply, and heating pipes will be used. Plastic pipes are used, 80% of urban water supply pipes (under DN400mm) are made of plastic pipes, 90% of village and town water supply pipes are made of plastic pipes, the application volume of urban gas plastic pipes (medium and low pressure pipes) reaches 40%, and 90% of building wire threading sheathing pipes are made of plastic pipes. It is predicted that during the 12th Five-Year Plan period, my country's plastic pipe production volume will maintain a growth rate of about 10%. By 2015, the national plastic pipe production volume is expected to be close to 12 million tons, and the market share of plastic pipes in various types of pipes in the country exceeds 60%.
