Since the late 1980’s the Chinese plastic pipe industry has maintained a high growth rate eventually becoming the largest producer of plastic pipe in the world. By 2010, the production of plastic pipe in China amounted to 8.4 million tons, with PVC, PE and PP pipe being the main products. Both the variety of pipe materials and the application of plastic pipe still continued to expand. At the same time, with the growing proportion of economic indicators among some key enterprises, the industry concentration continues to increase. Although there have been difficulties the Chinese plastic pipe has achieved many important milestones over the past five years and has laid a good foundation for future. It is believed that the Chinese plastic pipe industry will continue to grow at a rate more than 10% for the next 5 years. By 2015, the total output of China plastic pipe should reach 11 million tons. In the next few years, China development still fucus on PVC-U, PE and PP Pipe, meanwhile, modified plastic pipes, composite pipe and other new plastic pipe will also start to enter the market. With the increasing of application in the municipal, construction, water conservancy and other area, the application of plastic pipe in agriculture, trenchless, old pipeline rehabilitation, mine, petroleum and industrial areas will also grow steadily. In the past five years, the macro economy was greatly developed in China. The demand of the markets of construction, municipal engineering, water conservancy, agriculture and industry was continuously extending, which further boost the rapid development of China’s plastic pipe industry. China’s plastic pipe industry has made great process. Thus China is becoming one of the main countries of consumption and production for plastic pipes. Plastic was selected as a main material for producing pipes. During the next five years, plastic pipe industry should seize the opportunity to regulate the industrial structure, clear development goals and priorities, make great efforts to develop the application of plastic pipes and promote the healthy development of the plastic pipe industry. Based on the development of science and technology, we should strengthen innovation, develop new products and technologies with independent intellectual property rights, improve the conditions of plastic pipe system supporting and complete the application technology. We should maintain and continuously improve the high quality of the products. The rational distribution of 1 manufacturers should be encouraged, in order to form a reasonable industry cluster.
