Brian Fasteners manufactures Titanium Weld-Neck Flanges precision-machined from Grade 2 or Grade 5 titanium to ANSI/ASME specifications. A long tapered hub and full penetration weld potential define these flanges, which offer stress distribution and mechanical strength in high-pressure applications. With traceable certified material and close machining tolerances, Brian Fasteners supplies flanges for critical piping and structural use. Perfect for aerospace, chemical process, and offshore equipment, titanium weld-neck flanges provide corrosion resistance and strength for rigorous connection conditions.
They consist of CP Grade 2 or Ti‑6Al‑4V Grade 5. Grade 2 provides tensile strength ~345 MPa; Grade 5 ~860 MPa. Both retain strength from –250 to +400 °C and are resistant to chemical and marine corrosion. Weld-neck design provides strong, fatigue-resistant connections. Material has good toughness and weldability, accommodating high-pressure piping applications.
