Concentric & Eccentric Reducers

Concentric Reducers

Expansion joints installed in piping systems must be anchored on both sides of the joints to avoid the use of control rods. If control rods are installed as a safety measure, the locking nuts must be backed off with a clearance equal to the specified axial movement. The expansion joint will exert thrust on the anchors. To calculate thrust, use the following equation:

Thrust = (Thrust Area  Large End ID) x (Rated Working Pressure)

EXAMPLE— For a 12” x 10” FCR/FER500, the Thrust Area 133 in2 multiplied by the Rated Working Pressure 140 psi equals the Thrust 18,620 lbs.

133 x 140 = 18,620 lbs.
