Domestic valves imported more than 3 billion US dollars in less than half a year

Column:Technical article Time:2018-08-11
According to data released by China Customs, from January to May 2018, China imported 427.96 million sets of valves , an increase of 2.5% over the same period of last year.

In the development of the national economy, valves play an important role as an important part of the mechanical equipment manufacturing industry. As a subdivision of the manufacturing industry, the valve industry has been widely used in electric power, metallurgy, petrochemical, natural gas, environmental protection and other industries.
The continued increase in the global population and growing energy demand have spawned a large demand for valve products. As a developing country, China's rapid economic growth has greatly promoted the development of downstream industries such as oil and natural gas, and has gradually become a new engine for the development of the valve industry.
For example, in the natural gas industry, the “13th Five-Year Plan for Natural Gas Development” pointed out that during the “13th Five-Year Plan” period, the country will build 40,000 kilometers of natural gas trunks and supporting pipelines, and the total mileage will reach 104,000 kilometers in 2020; The "13th Five-Year Plan for Petroleum Development" pointed out that during the "13th Five-Year Plan" period, about 5,000 kilometers of crude oil pipelines will be built, and 12,000 kilometers of refined oil pipelines will be built. By 2020, 32,000 kilometers of crude oil pipelines will be built, and 33,000 oil products pipelines will be built. Kilometers. The large-scale construction of natural gas and oil pipelines will use a large number of valve products during the period, which will promote the development of China's valve industry.
It can be said that at present, China's valve industry is in a very favorable period of development. According to statistics, there are currently more than 3,000 valve manufacturing enterprises in China, ranking first in the world. They can produce gate valves , globe valves , throttle valves , ball valves , butterfly valves , diaphragm valves , plug valves , check valves , control valves, etc. Model specifications of valve products to meet the needs of different sectors of the industry.
However, China's valve enterprises are mostly low-level, small-scale, family-style enterprises, with problems such as low industrial concentration, backward technology, low product quality, and lack of influential brands. In the middle and high-end valve market, there are still insufficient developments in China's high-end valve products. The market is still dominated by internationally renowned companies, and the share of valve companies in China is very low. This means that China's valve industry has huge market development potential.
With the development of science and technology, the valve technology level and material technology are constantly improving. Some domestic valve companies and research institutes are investing a lot of money to focus on developing high-end valve products. For example, the high-end valves developed by the China Aerospace Science and Technology Group Sixth Institute continued to win the bid for the pipeline projects of Sinopec, CNOOC and local refinery markets, defeating the world's largest US plug valve manufacturer and breaking its monopoly in China's oil pipeline market. It ensures the safety of the national energy supply.
With the rapid development of China's economy and the country's continued investment in oil, natural gas, petrochemical, environmental protection, electric power and other fields, China's valve market will maintain rapid growth. According to the “2017-2021 China Valve Industry Investment Analysis and Prospect Forecast Report” issued by China Investment Consultant, the average annual compound growth rate of China's valve industry in the next five years (2017-2021) is about 1.97%, and the valve production will reach 2021. 8.86 million tons.
In today's increasingly fierce competition in the valve industry, valve companies must always maintain a sense of crisis, aim at market demand, strive to improve their technological innovation capabilities in the research and development of valve products, move toward the mid-to-high-end market, and strive to improve the quality and technology of valve products. High-end intelligent valve new products can gain more opportunities in the huge market demand, and help China's valve manufacturing industry to move from manufacturing to manufacturing countries!
