ASTM B381 Titanium Grade 7 Flanges are corrosion resistant forged flanges made of Ti-0.2Pd alloy that provides excellent resistance to acids, chlorides and reducing environments. These flanges are more durable than Grade 2 titanium and are used more in the chemical processing, offshore and marine industries.
Introduction to ASTM B381 Titanium Grade 7 Flanges
The ASTM B381 Titanium Grade 7 Flanges are some of the most robust components that can be found in industrial piping systems wherever durability in adverse conditions and long-life reliable performance is a must requirement. Titanium Gr. 7 (Ti-0.2Pd alloy) was developed to work under very hostile conditions where standard stainless steel and even regular titanium piping cannot stand their ground.
We manufacture, supply and export a complete series of Titanium Gr. 7 Forged Flanges in compliance with international codes such as the ASME B16.5 Titanium Grade 7 Flanges. Thanks to years of expertise and proven track record servicing sectors like chemical processing, marine application, desalination and power plants, we always ensure first-class quality, optimum cost-effectiveness and international reach.
