Titanium Grade 2 flanges, ASTM B381 Titanium Grade 2 flanges are commercially pure titanium flanges, with excellent corrosion resistance, high strength to weight ratio and superior performance in marine, chemical and offshore environments. These flanges are available in pressure classes like Class 150 Titanium Grade 2 Flanges, Class 300 ASTM B381 Gr 2 Flanges, and Titanium Gr 2 Flanges Class 600 / 900 / 1500 making them suitable for low as well as high-pressure applications.
They are widely used in industries like oil & gas, desalination, power plants, and chemical processing due to their durability and long service life.
Introduction to Titanium Grade 2 Flanges Manufactured as per ASTM B381 Standards
ASTM B381 Titanium Grade 2 flanges are made from commercially pure titanium, which has an ideal combination of strength, ductility, and corrosion resistance. Titanium Grade 2 is a better material for aggressive environments than stainless steel, such as seawater, chlorides and acidic environments.
We supply a complete range of flanges including:
- Slip-On Flanges
- Weld Neck Flanges
- Blind Flanges
- Socket Weld Flanges
- Threaded Flanges
These flanges comply with ASTM B381 standards, ensuring high quality and reliability in critical industrial applications.
