Compared with traditional cast iron pipes, galvanized steel pipes, cement pipes and other pipes, PPR pipes have the advantages of energy saving, material saving, environmental protection, light weight, high strength, corrosion resistance, smooth inner walls, simple construction and maintenance, and long service life. It is 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, electric power and optical cable sheath, industrial fluid transportation, agricultural irrigation, etc.
In recent years, with the increasing market demand in the construction industry, municipal engineering, water conservancy engineering, agriculture and industry and other industries, China's PPR pipe industry has shown a rapid development trend. In 2009, the production volume of plastic pipes was 5.804 million tons, an increase of 18.9% year-on-year. From January to September 2010, the production volume of plastic pipes was 5.528 million tons, an increase of 28.23% year-on-year. At the same time, as consumers continue to improve product quality requirements for environmental protection, health, durability, etc., while the output of plastic pipes in my country has increased, the product quality level has been continuously improved, the technological progress of the industry has been accelerating, and the number of brand-scale enterprises has continued to increase. Varieties of materials and new structures are constantly emerging, advanced system design concepts are emerging one after another, the functionality of products is more obvious, and the application fields are further broadened. Analysis believes that the market share of China's plastic pipes has exceeded 30% of all pipes.
By 2015, plastic pipes will be used for 85% of construction drainage pipes, 80% of construction rainwater drainage pipes, and 50% of urban drainage pipes will be used in urban drainage pipes. Water supply and hot water for buildings will be used by 2015. 85% of supply and heating pipes use plastic pipes, 80% of urban water supply pipes (below DN400mm) use plastic pipes, 90% of rural water supply pipes use plastic pipes, and 40% of urban gas plastic pipes (medium and low pressure pipes) are used in construction wires. 90% of the threading and sheathing tubes are made of plastic tubes. According to forecasts, during the Twelfth Five-Year Plan period, my country’s plastic pipe production will maintain a growth rate of about 10%. By 2015, the national plastic pipe production is expected to be close to 12 million tons, and the market share of plastic pipes in all types of pipes in the country will exceed 60%.
