In 2025, driven by the upgrading of industrial energy conservation and the localization of high-end equipment, the operating condition adaptability of stainless steel coils has achieved leapfrog improvement. Technological breakthroughs in extreme scenarios such as high temperature, high pressure, and strong corrosion have broken the long-term international monopoly in high-end fields.
In terms of core operating performance, domestic mass production and delivery of ultra-long 4,000-meter super duplex stainless steel seamless coils have been realized. These coils can withstand a high pressure of 15,000 PSI for a long time in a 300℃ high-temperature environment. Through the innovation of the whole-process technology, the processing error is controlled within 0.05mm, which greatly reduces the leakage risk in deep-sea oil and gas development. For the strong corrosion operating conditions in the chemical and energy fields, 316L stainless steel has been improved through nanoscale surface treatment and alumina/titanium dioxide composite coating technology. In the high-temperature flue gas environment containing 50ppm chlorine, the corrosion rate is reduced to 0.03mm/year, and the service life is more than 4 times that of traditional pipes.
Intelligent upgrading of operating condition adaptability has become a new trend. By embedding optical fiber sensors and machine learning algorithms, the stainless steel coils in the gas-steam combined cycle power generation system have reduced the fluctuation range of heat transfer efficiency to ±2.1% under full operating conditions; the array layout design has increased the energy efficiency ratio of the industrial waste heat recovery system by 18%-25%. After a steel enterprise applied this technology, the waste heat recovery efficiency of blast furnace flue gas jumped from 62% to 81%, reducing carbon dioxide emissions by 35,000 tons per year.
Industry data shows that the global demand for high-efficiency heat exchange equipment will exceed 120 billion US dollars in 2025. Relying on the adaptability advantage in extreme operating conditions, domestic stainless steel coils have climbed to 29% in the Southeast Asian market share. Experts point out that the comprehensive upgrading of operating condition adaptability not only promotes the transformation of stainless steel coils from basic components to core functional components, but also provides key technical support for the realization of my country’s industrial dual carbon goals.
