The corrosion resistance of glass plus the working strength of steel For this unusual demonstration, the faces of two steel discs 4" in diameter were glassed, then the discs were put face-to-face and fired at the same high temperature used in manu facturing Pfaudler glassed steel equipment. The bond between glass and steel, created by chemical action during thisfiring,locked the two pieces together so powerfully that the full weight (11,000 lbs.) of the truck failed to pull them apart. In a subsequent test, this bond withstood a pull of over 19,000 lbs., or 1,500 lbs./sq. in. High temperature firing locks Pfaztdler glass to steel and makes it hard and to%ghm Because it can be so durably bonded to steel, glass, with its almost universal corrosion resistance, is widely used for both pilot plant operations and full-scale production. Pf audler glassed steel reactors in capacities u p to 3500 gallons are commonplace in chemical proc essing today. These units are equipped with

agitation, can be jacketed, and are supple mented by a complete line of glassed steel accessories. Custom-built reactors as large as 8300 gallons, for severe chemical service, have been constructed. Glassed steel frac tionating columns and evaporators have solved many serious corrosion problems. Even at elevated temperatures and pres sures, Pf audler glassed steel is resistant to all acids except hydrofluoric. And now, with a new Pfaudler glass, it is possible to handle not only acids but also alkaline solutions up to pH 12 and up to 212°F. Thus it is possible to perform a wide variety of reactions in a single glassed steel vessel. Whenever you have an equipment problem requiring corrosion resistance, durability, and versatility, as well as the economy which these features provide, look to Pfaudler glassed steel for the solution.
