Class 300 F304/L Stainless Steel Slip On, Raised-Face Flange
Class 300 F304/L Stainless Steel Slip On Raised-Face Flange
The Class 300 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. The slip-on design allows the flange to slide over compatible pipe for convenient positioning and alignment before welding, making it a practical choice for many stainless steel piping installations.
ASME A/SA182 F304/L Stainless Steel
ASTM A182 / ASME SA-182 F304/F304L stainless steel offers excellent general corrosion resistance, mechanical strength, durability, and fabrication characteristics. F304L contains less carbon than F304, helping minimize carbide precipitation during welding and supporting corrosion resistance in heat-affected areas.
These stainless steel flanges are widely used in chemical processing, food and beverage production, pharmaceutical manufacturing, water treatment, power generation, utilities, manufacturing, pulp and paper, and industrial process piping systems.
Class 300 Slip On Flange Design
A slip-on flange has a bore that allows the flange to slide over the outside diameter of compatible pipe. After proper positioning, the flange is typically secured with fillet welds according to applicable piping codes, welding procedures, and system requirements.
The Class 300 designation identifies an ASME pressure class rather than a maximum operating pressure of exactly 300 PSI. Actual allowable pressure depends on 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. This configuration concentrates bolting force over the gasket to help establish a dependable 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 300 F304/L Slip On Flange
When ordering a Class 300 F304/L stainless steel slip-on raised-face flange, verify nominal pipe size, F304/F304L material, Class 300 rating, RF facing, ASME A/SA182 material specification, ASME B16.5 requirements, gasket, bolting, welding requirements, operating temperature, and process media.
