THE INTERNATIONAL NICKEL COMPANY OF CANADA, LIMITED

BEATS TOUGH CORROSION CONDITION

This 554-foot chimney was built* in 1936 for International Nickel of Canada to handle gases from copper reverberatories and con­verters. Now, after ten tough years, the smoke goes up this chimney just the same as the day the stack was built!

TEN YEARS WITHOUT REPAIR The gases contain SO2 with mois­ture content slightly above atmos­pheric humidity. Despite this corrosive condition, up to the pres­ent time no repairs have been made to this stack, and no evidence of deterioration has been noticed.

HERE'S WHY: The entire lining of this stack was built with acid-proof brick laid in

Penchlor Acid-Proof Cement.** In addition the top fifty feet of this stack was further protected by using Penchlor Acid-Proof Cement for pointing the outside surface joints. Penchlor Acid-Proof Cement is a superior sodium silicate cement that is quick-setting and self-hardening. Its outstanding record of satisfactory service has been proved in chemical plants, steel mills, paper and pulp mills, oil refineries and smelting plants.
