In recent years, the consumption of cross-linked polyethylene, ultra-high molecular weight polyethylene, heat-resistant polyethylene, modified polyvinyl chloride and other materials has increased rapidly; the continuous development, production and application of solid wall pipe, corrugated pipe, rib pipe, winding pipe, core layer foam pipe, spiral pipe and other structure pipes with different raw materials; more than 1500 utility models and invention patents in domestic plastic pipes; in ultra-high molecular weight polyethylene Pipe, steel plastic composite winding pipe for large diameter drainage, plastic metal composite pipe and other aspects have reached a certain international advanced level.

The plastic pipe industry is striving to move towards the goal of green environmental protection. As a plastic processing industry with the fastest development and large output value, it has the characteristics of relatively high overall technical level, rapid acceptance of new materials and technologies, and strong capability of technological transformation and new product innovation. During the 11th Five Year Plan period, China's plastic processing industry has achieved a historic leap, ranking among the world's largest plastic industry countries. In 2012, the output of China's plastic products exceeded 80 million tons, ranking top in the world since 2010. During the 12th Five Year Plan period, it has entered a new historical stage of innovation driven development.

Since 2012, the economic situation at home and abroad has been complex and changeable, the market demand continues to be weak, and the whole plastic industry has been in a downturn. However, with the domestic housing construction and municipal engineering stable domestic demand, the policy of water conservancy construction has been vigorously supported, the construction of rural drinking water safety system and the building materials going to the countryside to drive the demand upgrade of plastic pipes, the gas supply system and heating consumption trend demand increase, and the plastic pipes The industry still shows a good momentum of development.

However, in the process of rapid development of the industry, there are also overcapacity, homogenization of products, large proportion of general and low-grade products, imperfect product standard system and domestic special resin, additives and other raw materials that can not meet the production demand. Some functional pipeline products, such as fusible (fpvc), oriented (PVC-O) PVC pipe, high-pressure reinforced thermoplastic pipe (RPT), twining and fusion joint augmentation There are many problems such as the gap between the production technology of strong PE pressure pipe, self reinforced PE pipe and foreign countries.

All of these require us to make joint efforts with the upstream and downstream of resin, additives and users, and the whole industry to make key breakthroughs in many common and key technical issues of plastic pipes, change the overall backwardness of the plastic pipe industry, and comprehensively improve the overall quality of the pipe industry, so as to ensure the sustainable, stable and rapid growth of the plastic pipe industry and realize healthy development.

Especially as the representative of green pipeline in the field of chemical industry and construction industry, PP pipeline plays an increasingly important role in the plastic pipeline market because of its advantages such as small density, good corrosion resistance, long service life, good sanitation and environmental friendliness. In 2012, China's plastic pipeline production was 11 million tons, and the raw material consumption of PP pipe was about 550000 tons, including 230000 tons of raw material consumption of PP-R pipe.
