Concentric & Eccentric Reducer Expansion Joints



Reducers add a flexible component that is automatically self correcting for misalignment created by structural movements caused by settling, expansion or ground shifting.




Thorburn’s 42HP-CR Concentric Reducers & 42HP-ER Eccentric Reducers are designed to replace sound transmitting metal reducers. Pipe wall sound is that is carried through the piping system is absorbed when entering the rubber joint. Fluid born noise is absorbed by volumetric expansion which cushions water hammer and smoothes out pumping impulses.


Rigid attachment of piping to critical equipment can produce excessive loading. Thermal or mechanically created strain, stress and shock are cushioned and absorbed.


Benefits
• Absorbs pipe wall and fluid noise

• Easy to install

• Reduces system stress

• Compensates for misalignment

• Addresses limitations found in metal reducers

• Isolates vibration and motion

• Designed to connect piping of unequal diameters
