Case:

The proven performance of Baotou steel C90 casing has made it a trusted choice for major domestic projects across China’s key oilfields, including the complex sour reservoirs of the Sichuan Basin and the deep well projects in the Tarim Basin, often serving as critical intermediate casing for leading operators like CNPC and Sinopec. Internationally, our C90 products have been successfully supplied to and deployed in oil and gas projects across the Middle East (for sour gas applications), North America (for unconventional resource development requiring high-strength pipe), and Southeast Asia, establishing our global reputation for quality and durability that meets the stringent requirements of API 5CT and NACE MR0175standards.
