Grade 2 Titanium Lap Joint Flange

Titanium lap joint flanges are engineered for piping systems that require frequent assembly and disassembly while maintaining superior sealing performance and corrosion resistance.

When used in combination with a stub end, the lap joint flange allows the backing flange to be reused, significantly reducing maintenance costs and improving system flexibility in demanding industrial environments.

Gr2 titanium lap joint flanges are widely recognized for their balanced mechanical strength and excellent corrosion resistance, making them a reliable solution for aggressive media and long-service applications.
