Class 600 F304/L Stainless Steel Slip On, Raised-Face Flange
Class 600 F304/L Stainless Steel Slip On Raised-Face Flange
The Class 600 F304/L Stainless Steel Slip On Raised-Face Flange manufactured to ASME A/SA182 and ASME B16.5 requirements provides a strong, corrosion-resistant connection for demanding industrial pressure piping systems. Combining forged stainless steel construction with a convenient slip-on design, this flange delivers excellent durability, reliable sealing performance, and straightforward pipe alignment before welding.
ASME A/SA182 F304/L Stainless Steel
ASTM A182 / ASME SA-182 F304/F304L stainless steel provides excellent general corrosion resistance, mechanical strength, toughness, and fabrication characteristics. F304L has a lower carbon content than F304, helping minimize carbide precipitation during welding and supporting corrosion resistance in heat-affected areas.
Class 600 F304/L stainless steel flanges are used in chemical processing, petrochemical facilities, power generation, pharmaceutical manufacturing, food processing, water treatment, manufacturing, utilities, and industrial process piping systems.
Class 600 Slip On Flange Design
A slip-on flange features a bore that allows the flange to slide over the outside diameter of compatible pipe. Once correctly positioned, the flange is typically secured using fillet welds according to applicable piping codes, system design requirements, and qualified welding procedures.
The Class 600 designation identifies an ASME pressure class rather than a maximum working pressure of exactly 600 PSI. Actual allowable pressure depends on the material grade, flange size, operating temperature, and applicable pressure-temperature ratings.
Raised-Face Flange Construction
The raised-face (RF) design incorporates an elevated gasket seating area that concentrates bolting force over the gasket, helping create an effective seal between compatible flanged components.
ASME B16.5 establishes applicable requirements for flange dimensions, facing, bolt-hole patterns, tolerances, and pressure-temperature ratings.
Selecting a Class 600 F304/L Slip On Flange
When ordering a Class 600 F304/L stainless steel slip-on raised-face flange, verify nominal pipe size, F304/F304L material, Class 600 rating, RF facing, ASME A/SA182 material specification, ASME B16.5 requirements, pipe dimensions, gasket selection, bolting, welding requirements, operating temperature, and process media.
