Titanium Flanges (F-1 to F-38) — Frequently Asked Questions
Find answers to common questions about Titanium Flanges Manufacturer stock, ASTM B381 standards, and typical applications.
The material for our Titanium Flanges is sourced and certified to ASTM B381, which covers Titanium and Titanium Alloy Forgings (F-1 through F-38). This ensures the correct chemical composition and mechanical properties are met for the flange's critical application.
For Titanium Weld Neck Flanges, Flanges Grade F-2 (CP) is most common due to its excellent weldability and superior corrosion resistance in chemical media. For high-pressure systems where corrosion is secondary to mechanical strength, Flanges Grade F-5 (6AL-4V) is the preferred choice.
Yes, as a specialized Titanium Flanges Supplier and Exporter, we regularly manufacture and source non-standard items including Lap Joint Flanges, Spectacle Blinds, and high-pressure/large-diameter flanges as required by ASME B16.47 and special project specifications.
ASME B16.5 Class 1500 refers to the pressure-temperature rating of the flange. A higher class number (e.g., 1500) indicates the flange is designed for higher pressure service (or higher temperature service at a given pressure) compared to lower classes (e.g., Class 300).
