According to the company's understanding, the petrochemical equipment represented by oil refining, ethylene, and PTA needs to be used continuously under high temperature, high pressure, low temperature, corrosion and wear, so there are many special requirements for the structure, material and reliability of the equipment. .

From the perspective of industry development, the development trend of petrochemical plants is large-scale, highly automated and long-term operation, in order to pursue higher economic benefits. The large-scale plant also puts forward higher requirements for the design and manufacture of petrochemical plants.

Qian Jiaxiang said that at present, my country's petrochemical equipment industry has two major constraints. First, due to the long-term focus on stand-alone manufacturing, the engineering and integration capabilities are poor; second, the industry concentration is low. There are tens of thousands of petrochemical equipment companies across the country, but not many are really powerful.

Experts at the meeting believed that, in general, compared with developed countries, my country's petrochemical equipment has a certain gap in design theory and design method, and product development mostly adopts imitation and analogy methods, lacking theoretical basis and experimental research data; processing equipment and technology. The level is relatively backward, the processing accuracy is low, and the production efficiency is low; the degree of product serialization and generalization is not high, and the specifications and varieties are few; there is still a big gap in efficiency, quality and reliability, sealing performance, and corrosion resistance.

Petrochemical equipment

According to Qian Jiaxiang, by the end of the "Twelfth Five-Year Plan", the localization rate of general machinery and equipment in key fields such as petrochemicals will be 5-10 percentage points higher than that of the "Eleventh Five-Year Plan", and the market share will reach more than 85%. The output value of the whole industry reaches 1.5-1.8 trillion yuan. There will be 3-5 enterprises with an output value of more than 10 billion yuan, 5-10 enterprises with an output value of 5 billion yuan, and 60-80 enterprises with an output value of more than 1 billion yuan.

    In addition, relevant departments are pushing to increase the research and development of high-end and energy-saving products. By the end of the "Twelfth Five-Year Plan", strive to make the key unit technology of design and manufacture of high-end products such as large air separation plants, axial compressors, chemical process pumps, and various petrochemical valves reach the international advanced level. The industrial structure of the industry has changed significantly, and the proportion of mid-to-high-end products has increased from 25% in the "Eleventh Five-Year Plan" to 40%.

    It is reported that during the "Twelfth Five-Year Plan" period, the five key industries of petrochemical equipment, large-scale mechanical parts processing, pressure pipeline installation, fans, compressors, valves, and air separation will also establish engineering research centers and several corporate strategic alliances. Carry out joint product design with the participation of universities, research institutes and enterprises. Focus on cultivating a number of large-scale backbone enterprises such as Shenyang Blower Group, Shaanxi Blower Group, and Sichuan Air Separation Group to transform from pure manufacturing to complete engineering and modern service industries.
