ASME B16.5 BLRF Gr2 Gr5 Titanium Blind Flange Class 150 Raised Face
ASME B16.5 is a standard for Pipe Flanges and Flanged Fittings, and the BLRF (Blind Flange Raised Face) refers to a type of blind flange that features a raised face designed for sealing applications. The Gr2 (Grade 2) and Gr5 (Grade 5) refer to specific grades of titanium alloy commonly used for flanges.
- Grade 2 Titanium (Gr2) is commercially pure titanium, which offers excellent corrosion resistance and moderate strength.
- Grade 5 Titanium (Gr5) is an alloy of titanium with aluminum (6%) and vanadium (4%), offering higher strength than Gr2 and still maintaining excellent corrosion resistance.
- Class 150 refers to the pressure rating of the flange, suitable for piping systems with pressures up to 150 psi at ambient temperatures.
Features and Applications
- Corrosion Resistance: Both Gr2 and Gr5 titanium alloys are known for their exceptional resistance to corrosion, particularly in highly aggressive environments such as seawater, chemicals, and acids.
- High Strength-to-Weight Ratio: Gr5 titanium alloy provides higher strength compared to Gr2, making it ideal for applications requiring both lightweight and high strength.
- Pressure Rating: Class 150 ensures a reliable performance at low-to-medium pressure conditions.
- Sealing: The raised face on the flange provides a better sealing surface when used with gaskets in piping systems.
