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.

Key Specifications:

Material Standard: ASTM A182
Material: F91 Chromium-Molybdenum Alloy Steel
Type: Spectacle Blind Flange
Pressure Rating: Class 300 (300#)
Sealing Face: Raised Face (RF)
Dimension Standard: ASME B16.48
Customization: Non-standard sizes available
Application: Power generation, petrochemical processing, refineries, and high-temperature/high-pressure industrial piping systems

All flanges are precision forged and undergo rigorous quality inspection, including material composition analysis, mechanical performance testing, dimensional verification, and pressure testing, to meet international industrial standards, ensuring stable performance and long service life in extreme high-temperature environments.
