Product Description

ASME B16.5 BLRF Gr2 Gr5 Titanium Blind Flange Class 150 Raised Face For Piping Lines

ASME B16.5 BLRF Gr2 Gr5 Titanium Blind Flange Class 150 Raised Face

ASME B16.5 is the standard for Pipe Flanges and Flanged Fittings. The BLRF (Blind Flange Raised Face) is a specialized blind flange featuring a raised face designed for optimal sealing performance in piping applications. The Gr2 (Grade 2) and Gr5 (Grade 5) designations refer to specific titanium alloy grades commonly used in flange manufacturing.

Grade 2 Titanium (Gr2): Commercially pure titanium offering exceptional corrosion resistance with moderate strength characteristics.
Grade 5 Titanium (Gr5): Titanium alloy containing 6% aluminum and 4% vanadium, providing superior strength while maintaining excellent corrosion resistance.
Class 150 Pressure Rating: Designed for piping systems operating at pressures up to 150 psi under ambient temperature conditions.

ASME B16.5 Titanium Blind Flange with Raised Face

Features and Applications

Corrosion Resistance: Both Gr2 and Gr5 titanium alloys provide exceptional resistance to corrosion in aggressive environments including seawater, chemicals, and acids.
High Strength-to-Weight Ratio: Gr5 titanium alloy delivers superior strength compared to Gr2, making it ideal for applications requiring both lightweight construction and high structural integrity.
Pressure Rating: Class 150 certification ensures reliable performance in low-to-medium pressure operating conditions.
Sealing Performance: The raised face design provides an enhanced sealing surface when used with compatible gaskets in piping systems.
