If you process with ACETIC ACID, you need
the corrosion resistance of glass plus the working strength of steel For across-the-board corrosion resistance in processes using acetic acid, glassed steel is the most completely suitable material of construction available today. Glassed steel is fully resistant to dilute solutions of acetic acid up to the boning point and to all other concentrations up to at least 300 °F. Even at temperatures above 300 °F., glassed steel is sufficiently resistant to acetic acid attack to provide satisfactory, though not unlim ited, service life. Other materials are, of course, also used for acetic acid, but for wide application all are limited either by size, pressure, temperature, impurities, fragility, or cost. Glassed steel knows no such limitations. Pfaudler glassed steel is resistant to all acids except hydrofluoric, even at elevated temperatures and pres sures. With a new Pfaudler glass, it is possible to handle not only acids but also alkaline solutions up to a pH of 12 and 212 °F.
PFAUDLER
To give it working strength, Pfaudler glass is fused to steel in huge furnaces at temperatures of 15001700 °F. This high-temperature firing locks the glass to the steel and makes it hard and tough. Pfaudler glassed steel reactors, in capacities from 5 to 3500 gallons, for internal pressures as high as 200 p.s.i., are commonplace in chemical processing today. These units are equipped with agitation, are usually jacketed, and are supplemented by a complete Une of glassed steel pipe, fittings, and valves. Custombuilt vessels as large as 8300 gallons, for severe chemical service, have been constructed. Glassed steel columns solve many serious corrosion problems. 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.
