China has been manufacturing and utilizing plastic pipes for almost four decades, but the most significant progress has occurred in the past ten years. According to statistical data, the annual output of domestic plastic pipes and fittings has grown from 200,000 tons to 600,000 tons over the last decade, reflecting an average annual growth rate of approximately 20%. The application areas of plastic pipes are diverse, covering eight major fields: indoor water supply systems, building water supply lines, drainage pipes for buildings, underground drainage systems, gas pipelines, electrical conduits, agricultural irrigation, and industrial piping. Among these, construction and drainage pipes have experienced the fastest growth, while secondary and agricultural pipe development has also shown strong potential. However, the development of underground drainage pipes and gas pipelines still differs significantly from that seen in Other countries.
Despite this progress, the development of plastic pipe fittings, such as valves, lags behind the growth of the main pipes. According to expert analysis, the ideal ratio of pipes to fittings in construction should be 8:1. However, according to data from 1998, the production capacity ratio in China was around 20:1, indicating a serious imbalance. Although there has been a slight increase in the production of plastic fittings in recent years, the overall situation remains uneven. Most manufacturers of plastic pipe fittings are small-scale enterprises, with very few large or medium-sized companies involved in this sector.
This gap highlights the need for more investment and technological advancement in the fitting industry to match the rapid expansion of the plastic pipe market. As the demand for infrastructure and modern plumbing systems continues to rise, improving the quality and availability of fittings will become increasingly important for the sustainable growth of the industry.
