Titanium Grade 2 Flanges | World Titanium | Pipe Fittings

World Titanium selection of Grade 2 Titanium Flanges

World Titanium carries a wide range of Grade 2 Titanium blind flanges, Titanium weld neck flanges, and Titanium slip-on flanges that range from 1/2” (1.26 lbs) to 24” (461 lbs). World Titanium carries a wide selection of Titanium Pipe Fittings.

Dimensional tolerances conform to ASME B16.5. Flange bore diameters agree with standard ASME B36.9M Sch-40S wall pipe. Other bore diameters can be supplied on special order.

Flat Face Titanium Flanges are supplied with a serrated spiral finish per ASME B16.5 Other gasket surface finishes can be supplied on special order. Titanium flanges are permanently marked by electro-chemical etching in accordance with ASME B16.5.

Estimated Titanium flange weights are based on a density of .163 lbs/cubic inch.
