Baogang Co., Ltd. has Developed a more Advanced Rare Earth High-strength and High-toughness Oil Casing Product

Recently, a non-standard high-steel grade rare earth high-strength and high-toughness oil casing developed and produced by Baogang Co., Ltd. was successfully put into the well. This is the highest steel grade high-strength and high-toughness oil casing product currently promoted and applied in the industry.

High-strength and high-toughness oil casing is mainly used in deep wells, ultra-deep wells, shale gas, and oil and gas wells involving special geological environments of salt-gypsum layers. As the depth of oil and gas wells increases, the pressure and temperature downhole will also increase accordingly. This working environment not only requires the oil casing to withstand greater pressure and load but also requires the oil casing to maintain good stability and durability under harsh environments such as high pressure and high temperature. Therefore, the need for oil casing to consider both high strength and high toughness has always been a technical problem in the industry.

Faced with this challenge, the R&D team devoted themselves to research, gave full play to the positive role of rare earth and other alloy elements in steel, and deeply studied the strengthening and toughening mechanism and key influencing factors of high-strength and high-toughness special casing, solving the strength and toughness matching problem of non-standard high-steel grade rare earth high-strength and high-toughness oil casing. Finally, Baogang developed and produced high-strength and high-toughness oil casing, which not only meets the casing strength required by users but also fully meets the design index requirements in toughness.

Baogang Co., Ltd. successfully developed non-standard high-grade rare earth high-strength and high-toughness casing, an important manifestation of scientific and technological level and R&D and production strength. This achievement not only adjusted the product structure but also further enhanced the market influence and comprehensive competitiveness of Baogang's high-end oil casing, laying a solid foundation for Baogang's steel pipe products to explore new and climb higher.
