ASME B16.5 Titanium Weld Neck Flange Class 150
ASME B16.5 Titanium Weld Neck Flange Class 150
A titanium weld neck flange to ASME B16.5 is welded to the end of a piping system, where its long tapered hub transfers stress from the flange to the pipe and gives a robust, leak-free joint for high pressure service. These flanges are produced by casting, forging and precision machining in Gr1, Gr2, Gr5, Gr7 and Gr12 titanium, in Class 150 with RF, FF, TG or RJ faces. Titanium resists corrosion and withstands high temperature and pressure, so the flange suits demanding pipeline, petroleum and chemical environments, and custom sizes are available for easy installation onto pipes, valves and other equipment.
