Factors affecting the development of my country's plastic pipe industry

At present, the degree of marketization of plastic pipes in the country is relatively high, with a large number of production and operation enterprises, but mainly small and medium-sized enterprises, whose competitiveness is weak, and economies of scale are poor. In addition, due to the indifferent brand awareness of the plastic pipe industry, the market order is chaotic, and the structure is unreasonable. , Resulting in excess production capacity of ordinary pipes with low technical barriers, and high-tech PE pressure pipes for urban gas, water supply, drainage and sewage and large-diameter plastic pipes cannot fully meet the market demand, especially high-tech and production technology. Complicated pipe fittings, such as electrofusion pipe fittings and PE ball valves, can produce fewer manufacturers, and there are even fewer manufacturers that can provide a full range of products, and some pipe fittings still need to be imported. In addition, the production of qualified super large-diameter plastic pipes required for large-scale transportation and energy engineering projects at the national level is even blank.


The following major factors affect the development of the plastic pipe industry:


1. On the whole, my country's plastic pipe companies are relatively small, with insufficient funds and relatively backward technology.


Although there are many plastic pipe manufacturers in my country, most of them have an annual production capacity of less than 5,000 tons, while foreign plastic pipe manufacturers have an economic scale of production with an annual output of more than 20,000 tons, and the production capacity ratio of pipes and pipe fittings is unreasonable. At present, the production capacity ratio of pipes to pipe fittings is about 15:1, which is far from the normal application ratio of 8:1, and there are few types of pipe fittings. In addition, because plastic pipes are mainly used in infrastructure construction fields such as communications, construction, gas supply, water supply, and drainage, the long implementation period of the project leads to a long payment settlement time, which takes up a large amount of working capital, and requires production enterprises to have strong funds. The technical level of my country's plastic pipe industry is weaker than that of developed countries, and there is still a gap between scientific research strength and funding investment and demand. Especially in the aspects of plastic pipe processing equipment, mold quality, degree of automation and guarantee of production continuity, product quality, extrusion volume, etc., there is still a big gap compared with developed countries, and the international market competitiveness is not strong.


2. The plastic pipe industry is facing fiercer competition.


Compared with large international plastic pipe manufacturers, domestic companies are at a significant disadvantage in terms of capital, technology, management, and scale. Large foreign plastic pipe manufacturers may adopt joint ventures, sole proprietorship, and cooperation to invest and build factories in China. Market competition will More intense. Domestic enterprises must seize the favorable opportunity for market development in our country, actively expand production scale, reduce production costs, and achieve economies of scale; improve technological level, increase product types, improve product structure, meet the diversified needs of the market, and enhance the ability to resist risks and the market Competitiveness. In addition, the transportation cost of plastic pipes is relatively high, and a certain sales radius is often formed due to the transportation distance, which hinders the development and growth of plastic pipe companies to a certain extent.


3. The main raw materials depend on imports, and their prices fluctuate greatly.


The research and development of domestic plastic pipe materials lags far behind the development of the plastic pipe industry. Compared with foreign countries, the main manifestations are: there are few special resin grades and insufficient supply of raw materials; product quality is unstable; product specifications and varieties are not matched; various high-performance varieties and grades are not developed enough. At present, there are only a few resin manufacturers in China that produce special materials for pipes. The annual import of special pipe materials is equivalent to domestic production, which leads to the basic dependence on imports of raw materials such as PE and PEX. The supply and demand of PE special materials are imbalanced, and the PVC market gap is large. In order to fundamentally reverse the imbalance between supply and demand in the production of special resins for pipes, my country proposed in the "Tenth Five-Year Plan" and the 2015 long-term plan; according to the needs of the processing performance of my country's plastic products, special varieties should be developed, and based on the domestic, accelerate the production of special resins. Development to ensure the processing performance and quality of products. At present, Shanghai Petrochemical and other large domestic chemical companies can produce PE80, PE100 and other special pipe resins. With the development of domestic plastic pipe special materials, the situation of my country's plastic pipe industry relying on imports for major raw materials will improve.


In addition, the raw material used in plastic pipes is polyethylene (PE), which is a downstream product of the petrochemical industry, and its price is greatly affected by price fluctuations in the international crude oil market. Since 2003, the international crude oil market price has been on the rise, leading to the rise in the price of polyethylene (PE) and the increase in production costs of plastic pipe companies, which is not conducive to the stable development of plastic pipe manufacturers.
