The ASTM B381 Titanium Grade 2 Long Weld Neck Flange (RFWN) is a critical component in industrial piping systems, known for its outstanding corrosion resistance, strength, and reliability. Specifically, Titanium Grade 2 is a commercially pure titanium alloy that offers excellent performance in highly corrosive environments such as marine, chemical processing, and aerospace applications. The Long Weld Neck Flange (RFWN) design, combined with the titanium material, ensures superior performance in demanding conditions.
