They can be unchained, wrapped around the pipe, slid into place, and then expanded to create a watertight seal. Excellent for retrofit applications.

He’s had it on there since 2003 when we showed him how to splice Teflon expansion joints on air ducts at a different power plant!

In this system the hot combustion gasses from the kiln are passed up through the falling raw meal in a series of cyclones. The average preheater typically produces a hot feed that is 20% calcined when it enters the kiln, increasing the clinker output of the plant. Watch out for stainless steel that exhibits signs of chloride stress corrosion cracking on your preheater tower. Salts in the raw mix are often evaporated in the kiln and re-condense on cool points further upstream in the form of sodium chloride or potassium chloride.

The Pennguard Block lining system provides an impervious barrier for the inside of chimney flues, protecting them from acidic condensation. It is also an excellent insulator, which helps keep the temperature of your wet-scrubbed flue gas higher – reducing steam plume and liquid carryover.

We discovered that although the phenolic mortar could take hot sulfuric acid, as could the brick, there was a Viton (flouroelastomer) expansion joint right beneath the hot acid tank in this picture. Whenever the tank overflowed it destroyed the expansion joint – exposing the asphaltic membrane beneath to hot H2SO4, which caused membrane failure and allowed sulfuric acid into the concrete foundation. Call Interep for tips on your brick design to avoid situations like this.
