TITANIUM thermowell SAVES «10,000 A thermowell, used in a chemical reaction vessel at DuPont, was failing about every nine months from severe corrosion, even when fabricated from one of the best of the standard corrosion-resistant metals. The environment was dilute nitric acid and nitrogen oxide at temperatures exceeding 400F. Titanium was suggested as a material of construction. But, since such a unit would cost $300 against $95 for the existing installation, a careful total cost analysis was made. The findings were startling: DuPont corrosion engineers discovered that each time a thermowell f a i l e d , it cost the company $1500 in lost production and replacement labor. They estimated a service life for the titanium thermowell of at least five years (five to ten times as
REM-CRU TITANIUM
long as stainless) resulting in a saving of about $10,000.
As this case history shows, titanium's corrosion-resistance often makes it by far the most economical material. Yet, this versatile metal offers additional outstanding advantages . . . each sufficiently important to recommend it to designers and engineers. For example, titanium is unusually resistant to erosion by high-velocity fluids and to stress-corrosion cracking . . . withstands abrasion, shock and fatigue . . . has a uniquely high strength-weight ratio that means substantial reduction in weight and cost of material needed for a given use. When the going is tough for ordinary metals — try REM-CRU titanium. For specific recommendations, call or write REM-CRU today.
