Dog Bone Expansion Joints

Dog Bone Expansion Joints are highly specialized flexible connectors, primarily used in turbine-to-condenser applications in power plants. These joints are designed to absorb large thermal movements while minimizing forces on turbine exhaust flanges.

At LSI-Mech Engineers Pvt. Ltd., we manufacture both circular and rectangular Dog Bone Expansion Joints, custom-engineered for various turbine exhaust configurations including axial, downward, and upward exhausts. Our designs are widely used in power installations around the world due to their proven reliability and performance.

The Unique Dog Bone Profile Provide

• Maximum flexibility under thermal expansion
• Low reaction forces on sensitive turbine connections
• Enhanced structural stability
Each unit is engineered with precision, utilizing in-house FEA (Finite Element Analysis)
to ensure long-term durability, even under varying operating pressures and temperatures. These joints support reliable turbine-condenser operation across a wide range of load conditions.
