Titanium Flanges pair very low density with outstanding chemical resistance. We manufacture ANSI B16.5 Ti. Alloy Orifice Flange for precise flow lines. ASTM B381 governs forged titanium flanges in Grade 2 and Grade 5 alloys. Weld neck, slip-on, blind and socket weld profiles suit varied piping needs. Each flange undergoes hydro-testing before leaving our Mumbai machining facility. Chemical, marine and aerospace piping systems favour this strong, lightweight metal. We remain a dependable Titanium Flanges Supplier in India for repeat export orders.

Titanium Grade 2 Vs Grade 5 Flanges

Titanium Grade 2 Flanges (R50400)

Commercially pure, excellent corrosion resistance
Very good weldability, easy to fabricate
Preferred for chemical & marine piping
Lower strength, cost-effective for general duty

Titanium Grade 5 Flanges (R56400)

Ti-6Al-4V alloy, near-double Grade 2 strength
Best strength-to-weight ratio for high-load duty
Preferred for aerospace & high-pressure lines
Harder to weld, higher machining cost
