Class 900 ASME A/SA105 ASME B16.5 Steel Flange
Class 900 A/SA105 ASME B16.5 Steel Flange
The Class 900 ASME A/SA105 ASME B16.5 Steel Flange is engineered for demanding high-pressure industrial piping systems requiring exceptional strength, durability, and reliable sealing performance. Manufactured from forged carbon steel, Class 900 flanges provide heavy-duty connections for pipe, valves, pumps, pressure vessels, and other flanged equipment used in critical process applications.
ASTM A105 / ASME SA-105 Forged Carbon Steel
Manufactured from ASTM A105 / ASME SA-105 forged carbon steel, Class 900 steel flanges provide excellent mechanical strength, toughness, and durability. A105/SA-105 is widely specified for pressure-containing piping components in oil and gas production, petroleum refining, petrochemical processing, chemical plants, power generation, manufacturing, utilities, and high-pressure industrial process piping.
Material and system suitability should always be verified for the intended operating temperature, process media, and environmental conditions.
Class 900 High-Pressure Flange Applications
The Class 900 designation identifies an ASME pressure class and should not be interpreted as a maximum working pressure of 900 PSI. Actual allowable pressure depends on flange material, size, operating temperature, and applicable ASME pressure-temperature ratings.
Class 900 forged steel flanges are designed for demanding piping systems where higher pressure ratings and robust bolted connections are required.
Class 900 Steel Flange Configurations
Depending on nominal pipe size and system requirements, Class 900 A/SA105 steel flanges may be available in weld neck, blind, socket weld, threaded, slip-on, and other applicable configurations. Raised-face and ring-type joint facing options may be available depending on flange type and size.
ASME B16.5 Flange Requirements
ASME B16.5 establishes applicable requirements for flange dimensions, facing dimensions, bolt patterns, tolerances, materials, and pressure-temperature ratings, helping provide standardized compatibility throughout industrial piping systems.
When ordering a Class 900 A/SA105 ASME B16.5 steel flange, verify nominal pipe size, flange style, facing, material specification, pressure class, bore requirements, gasket selection, bolting, and operating conditions for dependable high-pressure piping performance.
