1.Plastic processing and plastic pipe industry
The plastics processing industry refers to the whole industry with plastic processing as the core, including the synthesis of various additives, additives, plastic processing machinery and molds. According to the statistics of China Plastics Association, in 2015, the plastic products industry achieved a main business income of 2.15 trillion yuan, an increase of 4.6% compared with 2014, and a profit of 130.2 billion yuan. From January to December 2015, the total output of enterprises above designated size in China's plastics processing industry was 75.68 million tons, up 0.95% year-on-year. Of which, the output in December was 7.739 million tons, up 4.96% year-on-year; the total export volume reached US$61.06 billion, an increase of 1.03%. The development of the plastics processing industry has shown a steady trend.Plastic pipes are an important category in the plastics processing industry. They are processed and produced from composite polymer materials using plastic extrusion molding, injection molding, steel-plastic composite processing technologies. Traditionally, China's gas, water supply, drainage, mining, power communications and other piping systems (pipes and fittings) are mainly made of cement or cast iron, steel pipes and other metals.
2.The development of foreign plastic pipe industry
Plastic pipes were used in supply and drainage systems in developed countries in the United States in the 1930s. In 1933, plastic pipes were first industrialized in France and the United States. In 1936, Germany developed and applied plastic pipes for water, acid and construction sewage.In 1939, the United Kingdom laid the world's first plastic water pipeline. Since then, with the development of the plastics industry, new plastic materials have been continuously introduced, which has led to the expansion of the application of plastic pipes. Good corrosion resistance and light quality have prompted plastic pipes to Various fields have gradually replaced traditional material pipelines.Plastic pipes have been in existence for more than 70 years, and have become relatively mature products in production technology, quality standard system, design and construction specifications. They are widely used in developed countries and regions such as Europe and America.After decades of development, the application of plastic pipes has been extensive, and there are many varieties of products. The main varieties are basically divided into three categories: PVC, PE and PP. In 2015, the global demand for plastic pipes will reach 22.5 million tons, and by 2017 it will reach 23 million tons.
3.Overview of the development of China's plastic pipe industry
Compared with developed countries such as Europe and the United States, China's plastic pipe industry started late, but it has developed rapidly. Since the 1970s, plastic pipes have been produced. In the early 1980s, it was promoted and applied in engineering construction. By 2008, the output reached 4.593 million. Tons, surpassing other countries to become the world's largest producer of plastic pipes, plastic pipes have been greatly developed in terms of quantity and variety .Subsequently, the state has promulgated a number of policy measures, proposed the application fields and development goals of various plastic pipes, gradually eliminated traditional pipes with high energy consumption and high pollution, and vigorously promoted the construction of plastic pipes in residential construction, urban municipal engineering, and transportation. The extensive application in various fields such as construction and agricultural irrigation has effectively promoted the rapid development of China's plastic pipe industry. At present, China has become a big country in the production and application of plastic pipes.In 2014, the output of PVC pipelines, PE pipelines and PP pipelines accounted for about 55%, 25% and 10% of the total output of plastic pipelines respectively, among which PE pipelines produced the fastest growth rate.
4.Industry market supply and demand situation and reasons for change
The supply of plastic pipes in China has grown steadily over the years. Compared with traditional steel, cast iron, cement and other materials, plastic pipes have the advantages of light weight, convenient transportation and construction, corrosion resistance and low energy consumption. China's plastic pipe industry has risen rapidly. After years of development, according to statistics from industry associations, by 2008, it has surpassed the United States to become the world's number one. In recent years, the overall development trend of China's plastic pipe industry has stabilized, and the industry has gradually entered a transition period of optimizing industrial structure and improving quality.The number of large-scale enterprises in the industry is increasing. There are more than 3,000 large-scale plastic pipe manufacturers in China, with an annual production capacity of more than 15 million tons.The plastic pipe industry has formed an industrial function cluster, and the production enterprises are mainly concentrated in the coastal economically developed areas.Enterprises that apply brand strategy gradually grow and form an advantage in competition.The technological advancement of China's plastic pipe industry has promoted the rapid growth of plastic pipe applications.
5.Industry marketization and competition pattern
China's plastic pipe industry has a high degree of marketization, and the plastic pipe industry has achieved rapid development since 2010. By the end of 2015, the output of plastic pipes reached 13.8 million tons, according to the “Plastic Pipeline Industry Committee” during the “Thirteenth Five-Year Plan” period. (2016-2020) Development Proposal, the total output of China's plastic pipe industry is expected to reach 14.35 million tons in 2016.Due to the fierce competition in the plastic pipe industry market, the market share is more dispersed.
6.Industry and upstream and downstream industries
The plastic pipe industry has strong correlation with the upstream and downstream industries. The upstream industry is mainly the petrochemical industry and some metal material suppliers. The downstream is mainly the municipal construction, minerals, agriculture, chemical, gas and other industries, among which the petrochemical and coal mining industries are It produces the raw materials needed for plastic processing and is also the downstream consumer of some plastic pipes.The main raw materials required for the production of plastic pipes are high-molecular materials such as polyethylene (PE), polyvinyl chloride (PVC), and polypropylene (PP), and some metal materials. Among them, PE and PP raw materials are mainly derived from petroleum and natural gas. China's PVC raw materials are mainly derived from coal.As one of the pillar industries in China, the petrochemical industry is the most important source of raw materials for the plastic pipe industry. Due to the fluctuation of international crude oil prices, the fluctuation of China's petrochemical industry has a greater impact on the production costs of enterprises in the plastic pipe industry. In recent years, the development of China's petrochemical industry is relatively stable, and the supply of raw materials for the plastic pipe industry is sufficient.The government's policies to accelerate the construction of new urbanization, strengthen the construction of rural drinking water projects, and accelerate the transformation of urban drainage networks have opened up new demand markets for the plastic pipe industry, promoted the transformation of the plastic pipe industry and optimized the industrial structure.
From the perspective of the national industrial policy layout, there will still be better market opportunities for the plastic pipe industry in the future. According to market changes, projects such as drainage, water supply, heating, and agricultural water-saving irrigation and rural drinking water safety consolidation projects for municipal construction are still The main application areas of plastic pipes.
