What Are Titanium Grade 2 Flanges?
Commercially pure piping connectors made of UNS R50400 titanium are known as titanium flanges. They are the go-to option for industrial systems that need to be extremely resistant to corrosion.
The material has a regulated iron and oxygen composition and is around 99% pure titanium. In oxygen-rich settings, this mixture produces a stable layer of TiO2 oxide that self-heals.
These flanges are resistant to seawater-induced stress corrosion cracking and pitting, as opposed to alternatives to stainless steel. Their density of 4.51 g/cm³ reduces the structural load requirements, making them 45% lighter than steel equivalents.
Complex fabrication is made possible by the combination of high ductility and moderate strength. You gain from dependable connections that do not require regular maintenance and can endure severe chemical exposure.

Key Industrial Applications
Desalination and Marine Systems: These flanges show complete resistance to corrosion from ambient seawater. They are perfect for offshore platforms where salt exposure is continuous, subsea pipes, and desalination heat exchangers.
Chemical Processing Facilities: Titanium grade 2 flanges are excellent at managing organic acids, alkaline solutions, and oxidizing media. When 316L stainless steel fails too soon, they are the favored option for producing chlorate and bleach.
Power Generation Facilities: These flanges are used in steam condenser systems to link titanium tubing to the main infrastructure. They prevent erosion from high-velocity cooling water while preserving system purity.
The non-reactive surface satisfies hygienic requirements for processing equipment in the food and pharmaceutical industries. Longer service life and contamination-free operation are advantages for your production lines.

Frequently Asked Questions
Q: What is the difference between Grade 5 and titanium flanges?
A: Grade 2 titanium is more ductile and resistant to corrosion than commercially pure titanium. Grade 5 (Ti-6Al-4V) is better suited for structural applications rather than optimal corrosion performance since it offers more strength but less ductility.
Q: Are these flanges appropriate for welding?
A: They do have outstanding weldability. To avoid ambient contamination and preserve joint integrity, inert gas shielding (argon) must be used during welding.
Q: Can reducing acids be handled by titanium flanges?
A: They thrive under oxidizing conditions. Grade 7 with palladium addition or Grade 12 for increased resistance are suggested for strong reducing acids.
Q: What kind of gasket face surface finish do you offer?
A: We provide flanges that satisfy ASME B16.5 specifications with a serrated spiral finish (125–250 Ra). This guarantees leak-free connections and appropriate gasket seating.
Q: Is embrittlement a problem for Grade 2 titanium?
A: It resists embrittlement very well. To avoid hydride formation in specific settings, however, keep an eye on hydrogen exposure at high temperatures using hydrogen content testing.
