Tsingshan Steel Pipe Successfully Develops Large-Diameter Thick-Walled Nickel-Based Alloy Pipe UNS N06625
Recently, Tsingshan Steel Pipe announced a major technological breakthrough—the successful development and mass production of high-performance nickel-based alloy large-diameter thick-walled pipe material UNS N06625, with specifications covering 323.9*40.49mm and 355.6*45.24mm. This marks a solid step forward for the company in the field of high-end material manufacturing, placing its technological strength among the advanced ranks both domestically and internationally.
UNS N06625, as a high-quality nickel-based alloy material, exhibits exceptional application potential in extreme working conditions such as aerospace, petrochemicals, and marine engineering due to its superior corrosion resistance, high-temperature strength, and good machinability. However, the manufacturing of large-diameter thick-walled pipes has always faced technical challenges such as difficult material forming, complex heat treatment control, and high quality control requirements. As a leader in materials science and engineering technology, our R&D team, through countless experiments and optimizations, has finally overcome a series of technical challenges, achieving comprehensive innovation from raw material selection and precision machining to heat treatment processes, ensuring the superior performance and stability of our products.
The successfully developed and delivered nickel-based alloy large-diameter thick-walled pipe not only meets the market’s urgent demand for high-performance, high-reliability materials but also fills gaps in several key technological areas both domestically and internationally. Its excellent comprehensive performance will provide strong material support for pipelines in heavily corrosive environments in the petrochemical industry, as well as deep-sea equipment, driving technological progress and industrial upgrading in related industries.
Faced with the rapid development of global materials science and increasingly fierce market competition, Qingshan Steel Pipe Co., Ltd. will seize this opportunity to continuously increase R&D investment, deepen industry-university-research cooperation, explore more application possibilities for new materials and processes, and strive to become a leading global supplier of high-end materials. We firmly believe that through unremitting efforts and innovation, we will continuously drive industry progress and contribute more to the development of human society.
