Product Description

ASTM A182 F9 Alloy Steel Spectacle Blind Flange 300# RF ASME B16.48 Customized Size

 

 

We supply spectacle blind flanges manufactured in strict compliance with ASTM A182 F91 (material standard) and ASME B16.48 (dimension standard), made from A182 F91 chromium-molybdenum alloy steel, with pressure rating Class 300 (300#) and sealing face Raised Face (RF). We also offer customized size services to meet specific project requirements.
 
A182 F91 is a high-performance Cr-Mo alloy steel, renowned for its exceptional high-temperature strength, creep resistance, and oxidation resistance, making it ideal for high-temperature and high-pressure piping systems. The spectacle blind design allows for quick isolation or connection of pipeline sections, with the solid blind side providing complete shut-off and the ring side enabling full flow. The RF sealing face ensures reliable leak prevention under extreme operating conditions.
