ASME A/SA105 ASME B16.5 Steel Flange
ASME A/SA105 Steel Flange
ASME A/SA105 steel flanges are forged carbon steel piping components manufactured for dependable connections in industrial pressure piping systems. Known for strength, durability, and versatility, A/SA105 forged steel flanges are widely specified throughout oil and gas, petrochemical, power generation, manufacturing, utility, mechanical, and general industrial applications.
ASTM A105 / ASME SA-105 Forged Carbon Steel
ASTM A105 and ASME SA-105 cover forged carbon steel piping components intended for pressure systems at ambient and higher-temperature service conditions. A/SA105 material is commonly used to manufacture steel pipe flanges, forged fittings, valves, and other pressure-containing components requiring reliable mechanical performance.
Forged construction provides the strength and structural integrity required for demanding piping installations. Depending on the application, A/SA105 flanges may also be supplied in normalized conditions when required by the applicable specification.
A/SA105 Steel Flange Types
A/SA105 carbon steel flanges are available in multiple configurations to meet different installation requirements. Common types include weld neck flanges, slip-on flanges, socket weld flanges, threaded flanges, blind flanges, and lap joint flanges.
Pressure Classes, Facing, and ASME Standards
A/SA105 forged steel flanges are available in multiple ASME pressure classes. The pressure class is not the same as a specific PSI rating; allowable working pressure depends on material, temperature, and the applicable pressure-temperature tables.
Common flange facing options include raised face (RF), flat face (FF), and ring-type joint (RTJ) where applicable. Flanges may also require specific bores to match the connecting pipe schedule.
A/SA105 steel flanges are commonly manufactured to ASME B16.5 dimensional requirements for applicable sizes and classes.
When ordering an ASME A/SA105 carbon steel flange, verify nominal pipe size, pressure class, flange type, facing, bore or schedule, and applicable dimensional standard. Correct selection helps provide accurate alignment, dependable gasket sealing, and long-lasting performance in industrial piping systems.
