Class 150 ASME A/SA182 304/304L Stainless Steel Flange
Class 150 ASME A/SA182 304/304L Stainless Steel Flange
The Class 150 ASME A/SA182 304/304L Stainless Steel Flange provides a durable, corrosion-resistant connection for commercial and industrial pressure piping systems. Combining Class 150 pressure-class construction with forged or rolled 304/304L stainless steel, these flanges offer excellent strength, dependable sealing, and long service life in a wide range of process 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 service. F304/F304L stainless steel provides excellent general corrosion resistance, strength, durability, and fabrication characteristics.
The lower carbon content of 304L stainless steel helps reduce carbide precipitation during welding, making it especially suitable for welded piping systems where maintaining corrosion resistance in heat-affected areas is important.
Class 150 Stainless Steel Flange Applications
Class 150 A/SA182 304/304L stainless steel flanges are commonly used in chemical processing, food and beverage production, pharmaceutical manufacturing, water treatment, power generation, manufacturing, utilities, pulp and paper, and general industrial process piping.
The Class 150 designation identifies a pressure class rather than a maximum working pressure of exactly 150 PSI. Actual allowable pressure depends on material grade, flange size, operating temperature, and the applicable pressure-temperature rating.
Available Class 150 Flange Styles
Depending on piping requirements, Class 150 304/304L stainless steel flanges may be available in weld neck, slip-on, socket weld, threaded, blind, and lap joint designs. Facing configurations can include raised face (RF) and flat face (FF) where applicable.
Selecting a Class 150 304/304L Flange
When ordering a Class 150 A/SA182 304/304L stainless steel flange, verify nominal pipe size, F304/F304L material grade, flange style, facing, pipe schedule or bore, dimensional standard, gasket selection, bolting requirements, operating temperature, and process media for dependable industrial piping performance.
