Flange Types
Titanium Flanges
Lightweight, corrosion-resistant flanges for the most aggressive chemical environments.
Titanium flanges offer an unmatched combination of corrosion resistance, low density, and strength for piping systems exposed to the most chemically aggressive environments. Titanium resists virtually all chloride-containing solutions, most oxidizing acids, seawater, and wet chlorine gas. It weighs approximately 45% less than steel, which is significant in weight-sensitive installations such as offshore platforms, shipboard piping, and elevated pipe racks.
The most common grades for flange applications are Grade 2 (commercially pure, UNS R50400) for general corrosion service and Grade 5 (Ti-6Al-4V, UNS R56400) for high-strength applications. Grade 7 (Ti-0.15Pd) and Grade 12 (Ti-0.3Mo-0.8Ni) add palladium or molybdenum-nickel for improved resistance to reducing acids and crevice corrosion. All titanium flanges are forged per ASTM B381.
Flanges.AI supplies titanium flanges in weld neck, blind, slip on, socket weld, threaded, and lap joint configurations per ASME B16.5, in sizes from 1/2" through 12" and pressure classes 150 through 600 (larger sizes and higher classes available on request). Applications include chlor-alkali plants, bleach manufacturing, desalination, pharmaceutical, and marine systems. Contact us for availability and lead times on your titanium flange specification.
