What is a Damping Pad?

A damping pad is a preformed laminated fabric pad of manufactured material composed of layers of tightly twisted, closely woven lightweight material.  Each layer is made up of an elastomeric compound containing mold and mildew inhibiting agents.

What is it Used For?

Because steel smoke stacks have relatively low inherent structural damping, excessive top-of-stack deflection can result at critical wind speeds due to vortex shedding.  To keep these deflections within acceptable limits, a damping pad is placed between the stack base plate and concrete foundation and conforms to the exact shape and size of the base plate.

 

Features and Benefits of Damping Pads

 

Resist effects of steam, water, mildew and brine

Impervious to most oils and solvents

Creep effects are reduced to a limit of 5% of original thickness

 

Thicker sections can be supplied by bonding standard thicknesses together.

Unusually high compressive strength - 12,000 psi

 

Can be custom fabricated to any shape or size.

Can be supplied in nominal thicknesses of 1/16" (1.6 mm) up to 1" (25.4 mm)

 

Can be used for temperatures ranging from -65 degrees F (-54 degrees C) to 200 degrees F (93 degrees C)

Do not increase wind loads
