China's market status and development trend of plastic valve products

China has had nearly 40 years of history in the production and application of plastic pipes, but it has been a remarkable development for the past 10 years. According to statistics, the annual output of domestic plastic pipe and fittings has increased from 200,000 tons to 600,000 tons in the past 10 years, with an average annual growth rate of approximately 20%. According to relevant information, the application fields of plastic pipe can be roughly divided into 8 aspects: indoor water supply pipe, building water supply pipe, construction drainage pipe, buried drainage pipe, gas transmission pipe, electrical bushing, agricultural pipe, and industrial pipe. Among them, the construction and drainage pipes have the fastest development, and the development of secondary and industrial use pipes is also relatively good. The development of buried drainage pipes and gas pipelines has a large gap with foreign countries.

However, the development of pipe fittings such as plastic valves in China is relatively backward compared to the development of pipe materials. According to the theory of relevant experts, the reasonable ratio of construction pipe and pipe fittings should be 8:1, but according to statistics from 1998, the production capacity of plastic pipes and fittings for construction in China is about 20:1. In recent years, the production capacity of plastic pipe fittings has increased slightly, but it is still very unbalanced. The participation of plastic pipe fittings producers is dominated by small enterprises, and there are few large and medium-sized enterprises.

In addition, at present, China does not have a relatively uniform and perfect plastic pipe product technology and quality standards. Because of this, domestic plastic pipe products are far from satisfactory in terms of variety and quality. In particular, plastic valves are more difficult to meet in many fields because of relatively high production difficulty.

Market demand for plastic valve products mainly comes from two aspects: First, supporting the use of plastic pipe; Second, the plastic valve corrosion resistance, chemical resistance, fatigue resistance, good insulation, but also has a light weight, processing High efficiency and unique advantages. In foreign countries, plastic valves have been widely used in chemical, pharmaceutical, food processing, indoor and outdoor water supply and drainage, mechanical and electrical products, agriculture and other fields. It can be expected that plastic valve products with high quality, performance, and price will have huge market potential in China. Even if China enters the WTO, it will be a good product to participate in the international market competition.
