Abstract: Pressure vessel is a kind of pressure-bearing special equipment with a large quantity and wide applications, showing the potential hazard of leakage and explosion. China lists pressure vessels as high-end equipment, requiring to improve product quality and core competitiveness. Since the beginning of this century, scientific and technological workers in China have continued to carry out research and exploration and engineering practice in pressure vessel design and manufacturing under extreme conditions, lightweight green manufacturing of heavy-duty pressure vessels, risk-based integrity management, digital design, manufacturing and maintenance, etc. The applications of these achievements have made China’s petrochemical plant high-end pressure vessels basically no longer rely on imports, the level of green manufacturing technology has been significantly improved, and the long-term operation and maintenance capability has been significantly enhanced. This paper first briefly reviews the progress of pressure vessel design, manufacturing and maintenance technology in China since the beginning of this century. Focusing on major national strategies such as advancing new industrialization, moving faster to boost China’s strength in manufacturing and product quality, implementing industrial infrastructure reengineering projects and major technical equipment research projects, the technical problems that need to be solved urgently are elaborated from four aspects including robust industrial foundations, extreme manufacturing, green manufacturing and smart manufacturing. Facing the new application scenarios and the application of a new generation of artificial intelligence technology in the next two decades, the development trend of pressure vessels is technically foreseen.
