Recently, the ultra-pure corrosion-resistant large-diameter stainless steel pipe developed by ZGBZ Special Alloy Technology Group has achieved mass production, marking ZGBZ's successful entry into the field of high-end stainless steel suppliers for nuclear power.
With the successful trial production of large-diameter stainless steel pipes, ZGBZ signed contracts with customers for the first batch of large-diameter stainless steel pipes for the fourth-generation demonstration fast reactor project, and signed contracts with many well-known companies. The orders on hand reached more than 70 million yuan. . At present, large-diameter stainless steel pipe products are being produced at full speed.
The demonstration fast reactor project is a major national nuclear energy science and technology project and the main reactor type of the fourth-generation advanced nuclear energy system. It can greatly increase the utilization rate of natural uranium resources and effectively solve technical problems such as low utilization rate of nuclear materials and difficult disposal of nuclear waste.
In recent years, in the face of an increasingly competitive market environment, ZGBZ has made adjustments to the special steel product structure by visiting and investigating the nuclear power product market, digging into customer needs, and combining the company’s 36,000-ton ferrous metal vertical extrusion press with equipment features and technical advantages. And optimization, and continuously expand product application areas. As the most important core equipment of the project, large-diameter stainless steel pipes have extremely strict requirements on carbon content, high temperature performance, various inclusion levels, and trace elements in terms of smelting. In order to promote the project to achieve breakthroughs, the ZGBZ scientific research team has analyzed the material indicators many times, focused on each production link, and solved the sudden problems in the smelting process in time. After more than a year, it has developed a large-caliber high purity Stainless steel pipes have cultivated new economic growth points for promoting the high-quality development of ZGBZ.
