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.
I 2015 vil 85 % af bygningsdræningsrør over hele landet bruge plastikrør, 80 % af byggeri af regnvandsdrænrør vil bruge plastrør, brugen af plastikrør i bydræningsrør vil nå op på 50 %, og 85 % af bygningsvandforsyning, varmtvandsforsyning og varme. Plastrør anvendes, 80% af byvandsledninger (under DN400mm) er lavet af plastrør, 90% af landsby- og byvandsledninger er lavet af plastrør, anvendelsesvolumen af bygas-plastrør (mellem- og lavtryksrør) når 40%, og 90% af bygningstrådsgevindbeklædningsrør er lavet af plastikrør. Det forudsiges, at mit lands produktionsvolumen af plastrør i løbet af den 12.- femårsplanperiode vil opretholde en vækstrate på omkring 10 %. I 2015 forventes den nationale produktion af plastrør at være tæt på 12 millioner tons, og markedsandelen for plastrør i forskellige typer rør i landet overstiger 60%.
