Refining and chemical equipment refers to special equipment for oil refining and chemical production, but does not include general equipment such as packaging machinery. According to the "Classification and Codes of National Economic Industries" (GB/T 4754-2017) formulated by the National Bureau of Statistics, the special equipment manufacturing industry for oil refining and chemical production belongs to the special equipment manufacturing industry for chemicals, wood and non-metal processing in the special equipment manufacturing industry (C35). Equipment manufacturing industry (C352), its statistical level 4 code is C3521.

The upstream industries of the refining and chemical equipment industry mainly include the iron and steel industry, non-ferrous metal industry and machinery basic parts industry. The iron and steel industry provides all kinds of steel for the refining and chemical equipment industry, which are used for the production of support, main structural parts and non-standard mechanical parts of the refining and chemical equipment; the non-ferrous metal industry provides non-ferrous metal raw materials for the refining and chemical equipment industry, which are used for refining and chemical equipment Production of spare parts; mechanical basic parts provide various standard mechanical parts including valves and pipe fittings for the oil refining and chemical equipment industry.

In recent years, with the rapid development of my country's economy, the demand for oil (imports) has increased significantly, and the oil refining capacity has also continued to grow. The domestic oil refining capacity has reached 831 million tons, achieving three consecutive years of growth. However, despite the continuous increase in my country's oil refining capacity, the average operating rate of national refineries is 72.9%, which is the lowest in the world. In addition, the production and sales of refining and chemical equipment have declined year after year in recent years. Among them, the output of domestic refining and chemical special equipment was about 1.622 million tons, a year-on-year decrease of 6.84%; the sales volume was about 1.499 million tons, a year-on-year decrease of 10.72%.

With the development of my country's coal-to-oil industry and the vast markets in Central Asia and Russia brought about by the "Belt and Road", the refining and chemical equipment industry will still have a large room for development within a period of time. It is predicted that the output of my country's refining and chemical equipment industry will still increase slightly.

In recent years, with the rapid development of my country's economy, the demand for oil (import) has increased significantly. In order to meet the rising demand for oil processing products in China, my country has accelerated the construction of oil refining capacity, not only proposed to focus on the construction of Changxing Island in Dalian (West China Island), Hebei Caofeidian, Jiangsu Lianyungang, Shanghai Caojing, Zhejiang Ningbo, Guangdong Huizhou, Fujian Gulei seven petrochemical industry base construction, also proposed to support private and foreign-funded enterprises wholly or holding investment in petrochemical industry, speed up refining capacity and structural adjustment.

In this context, my country's oil refining capacity has grown rapidly, from 304 million tons to 931 million tons. The domestic oil refining capacity has increased for three consecutive years, of which a net increase of 22.25 million tons/year (new capacity of 33.9 million tons/year, eliminated The backward capacity is 11.65 million tons/year), and it is expected that local private large-scale refining and chemical projects will be put into operation one after another. The national crude oil processing capacity will increase by 32 million tons/year, and the excess capacity will reach 120 million tons/year.

Although my country's oil refining capacity continues to rise, the average operating rate of refineries across the country is 72.9%. In addition, in recent years, the production and sales of refining and chemical equipment in my country have declined year after year. The output of domestic refining and chemical special equipment was about 1.622 million tons, a year-on-year decrease of 6.84%; the sales volume was about 1.499 million tons, a year-on-year decrease of 10.72%.

In recent years, as powerful domestic enterprises have increased investment in scientific research and technology development, the technical level of China's oil refining and chemical equipment has been greatly improved. The modular design, construction and assembly of Zhejiang Petrochemical 4000 by Wison Engineering The ethylene cracking furnace unit of the 10,000-ton/year refinery and chemical integration project has a single ethylene production capacity of 200,000 tons/year, creating the world's largest single modular manufacturing precedent, with a height of about 53 meters and a total weight of about 3689 tons; the core equipment used by China First Heavy Industry Group in the 40 million tons/year refining and chemical integration project of Zhejiang Petrochemical Company - the 3000-ton slurry bed forging-welding hydrogenation reactor is the world's largest single-weight forging-welding structure hydrogenation reaction device etc.

Although in recent years, driven by the large-scale and planned development of the refining and chemical industry, the technical level of the refining and chemical equipment industry has been able to rise rapidly. However, due to the fact that the production enterprises in my country's oil refining and chemical machinery industry are generally small in scale and lack large-scale leading enterprises, the industry concentration is still low. The top ten enterprises in the industry only account for about 30% of the entire market. Among them, Lanzhou Lanshi, China Yizhong, Jinxi Chemical, Dalipu, etc. are relatively large-scale production enterprises.

Therefore, in the future, as the petrochemical industry continues to shift gears and upgrades, refinery and chemical equipment companies need to speed up investment in scientific research and technology development, develop new products with high technological content and more environmental protection, and enhance their independent innovation capabilities and industrial competitiveness.
