Recently, BAOGANG has added a new "Super" force in high-alloy seamless steel pipe manufacturing. Its steel pipe company has successfully trial-produced Super13Cr rare earth corrosion-resistant oil casing. This landmark achievement fills the gap in BAOGANG's martensitic stainless steel corrosion-resistant pipe products.

Super13Cr oil casing is a high-performance martensitic stainless steel corrosion-resistant pipe. Compared with Ordinary13Cr stainless steel pipes, Super13Cr oil casing adds nickel, molybdenum, copper, and other alloy elements during smelting, making it stronger, better at low temperatures, and more resistant to carbon dioxide and hydrogen sulfide corrosion. This can meet the "three super" oil and gas resource development and application of ultra-deep, ultra-high pressure, and ultra-high temperatures.

The unique resource advantage has created the "rare earth steel" characteristics of BAOGANG Co., Ltd. The steel pipe company relies on this characteristic advantage and adopts rare earth microalloying treatment to improve the organizational structure and inclusion morphology of rare earth elements in the material, forming a dense oxide film, and significantly improving the corrosion resistance of Super13Cr oil casing. At the same time, the whole process control process technology such as hot rolling, heat treatment, and flaw detection is applied in the production process to ensure product quality and dimensional accuracy and achieve a zero breakthrough in BAOGANG Co., Ltd. Super13Cr rare earth corrosion-resistant casing.

The successful trial production of Super13Cr rare earth corrosion-resistant casing not only accelerates BAOGANG Co., Ltd.'s seamless pipe products to move towards "new" and breakthrough technical difficulties, making scientific and technological innovation the "main engine" for the development of new quality productivity, but also will more effectively promote BAOGANG Co., Ltd.'s "rare earth steel" to climb to stronger performance, wider fields, and higher quality, continue to consolidate the core competitiveness of products, and strengthen the brand advantage of "Rare Earth Steel".
