Exceptional Strength and Corrosion Resistance for Extreme Downhole Drilling and Subsea Environments
The harsh environments of marine or underwater applications as well as the downhole environment in land-based energy exploration require machinery and components with exceptionally high resistance to corrosive elements.
Downhole drilling environments are often space constrained - making Belden u-joints superior strength-to-diameter ratio extremely valuable in Oil & Gas exploration and production in downhole applications.
Belden Universal Joints are widely used in downhole motors, mud motors, and rotary steerable systems (RSS) throughout the Oil & Gas industry. Directional drilling technology relies on the Belden u-joint's toughness, compact dimensions, and wide array of available materials for the most challenging drilling environments.
Belden offers stainless steel universal joints and telescoping driveshafts for such operating conditions. The yokes, pins and blocks of the universal joints are made of highly corrosion resistant 316L stainless steel. To prevent galling and improve the joints’ friction properties, pins, blocks and the yokes’ contact surfaces can be coated with layers of PTFE or MoS2. Additional protection against dirt and debris can be added by protective boots which can be also packed with Naval Grade grease.
