ASME A/SA182 304/304L Stainless Steel Flange
ASME A/SA182 304/304L Stainless Steel Flange
The ASME A/SA182 304/304L Stainless Steel Flange provides a strong, corrosion-resistant connection for demanding commercial and industrial piping systems. Manufactured from forged or rolled stainless steel, these flanges combine excellent mechanical properties, dependable sealing performance, and outstanding general corrosion resistance for pressure-containing piping applications.
ASTM A182 / ASME SA-182 F304/F304L Stainless Steel
ASTM A182 / ASME SA-182 covers forged or rolled alloy and stainless steel pipe flanges, forged fittings, valves, and related components intended for pressure systems. F304 and F304L stainless steel are widely specified austenitic stainless grades offering an excellent combination of strength, corrosion resistance, fabrication characteristics, and durability.
304L stainless steel has a lower carbon content than standard 304, helping reduce the risk of carbide precipitation during welding. This makes 304L particularly useful for welded piping systems where corrosion resistance in the heat-affected area is important.
304/304L Stainless Steel Flange Applications
A/SA182 304/304L stainless steel flanges are commonly used in chemical processing, food and beverage production, pharmaceutical manufacturing, water treatment, power generation, pulp and paper, manufacturing, utilities, and general industrial process piping.
The stainless steel construction provides excellent resistance to rust, oxidation, and many common corrosive environments while maintaining the strength required for pressure piping components.
Flange Styles and Pressure Classes
Depending on size and application, A/SA182 F304/F304L flanges are available in weld neck, slip-on, socket weld, threaded, blind, and lap joint configurations. Facing options can include raised face (RF), flat face (FF), and ring-type joint (RTJ) where applicable.
Pressure classes can include Class 150, 300, 600, 900, 1500, and 2500, depending on flange configuration, size, and governing dimensional standard.
Selecting a 304/304L Stainless Steel Flange
When ordering an A/SA182 304/304L stainless steel flange, verify nominal pipe size, F304/F304L grade, pressure class, flange style, facing, pipe schedule or bore, dimensional standard, gasket, bolting, operating temperature, and process media for dependable industrial piping performance.
