The industry of brake blocks for oil drilling rigs in China has gradually upgraded alongside the deep expansion of oil and gas exploration and development. In the 1980s and 1990s, the demand for onshore shallow well drilling drove brake blocks into mass production. At that time, products were mostly made of cast iron and asbestos-based friction materials to meet basic braking needs. Since the turn of the century, the rapid development of deep well and ultra-deep well platform drilling has imposed stringent requirements on brake blocks, including high-temperature resistance, impact and wear resistance, and adaptability to large-tonnage rigs. This has driven the material iteration towards resin-based composite friction materials and ceramic-reinforced friction materials, with structural upgrades to integrated designs incorporating heat dissipation grooves. In recent years, high-end demands driven by shale gas development and oil and gas exploration have accelerated the industry's transformation towards "high safety redundancy, long service life, and environmentally friendly asbestos-free" products. Currently, China has become a core global supplier of brake blocks for oil drilling rigs, with products covering all scenarios, including onshore conventional rigs, offshore semi-submersible rigs, and rigs dedicated to shale gas.

We have established a specialized testing team for brake blocks for oil drilling rigs, offering customized testing services for friction and wear performance, density, impact strength, and more, based on drilling depth, load level, and operating environment (high temperature, high humidity, corrosiveness), helping products meet safe braking requirements under extreme working conditions.
