Titanium Grade 2 Flanges

Titanium grade 2 flanges specifications

What are titanium grade 2 flanges?

These products use pure alpha titanium – a combination of ti with carbon, hydrogen, nitrogen, oxygen, and iron. titanium grade 2 flanges work in aerospace, chemical processing, automotive, power (and nuclear) generation, and oil and gas. They are available in different designs, for instance, a b381 grade f2 rtj flange.Piping systems needing to seal/terminateconnections in high-stress environments use an titanium gr2 blind flanges.


Which unique properties of titanium grade 2 flanges make them popular for high-performance applications?

They show brilliant tolerance for high-corrosion environments, aqua regia, chlorides, and seawater. A grade 2 titanium flange displays weldability and formability despite being sturdy and durable. Moreover, sb 381 grade 2 pipe flanges (the specification for annealed titanium forgings) maintain their strength and oxidation resistance up to 400°f to 600°f.Their biocompatibility helps them play a critical role in orthopaedic joint and bone replacements.

What are the cost-saving benefits of using titanium grade 2 flanges over other materials?

The significant benefit stems from the superior strength-to-weight ratio of an ASTM B381 gr 2 weld neck flange: one of the strongest per unit mass. Clients can incur cost savings because lesser quantities by weight of titanium gr 2 forged ring are required, compared to alternatives like stainless steel.
