Class 150 F304/L Stainless Steel Slip On, Raised-Face Flange
Class 150 F304/L Stainless Steel Slip On Raised-Face Flange
The Class 150 F304/L Stainless Steel Slip On Raised-Face Flange manufactured to ASME A/SA182 and ASME B16.5 requirements provides a durable, corrosion-resistant connection for commercial and industrial piping systems. The slip-on design allows the flange to slide over the pipe, providing convenient positioning and alignment before welding while delivering reliable performance in a wide range of pressure piping applications.
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 commonly used in chemical processing, food and beverage production, pharmaceutical manufacturing, water treatment, power generation, manufacturing, utilities, and general industrial process piping.
Class 150 Slip On Flange Design
A slip-on flange is designed with a bore that allows the flange to slide over the outside diameter of compatible pipe. After proper positioning, the flange is typically secured using fillet welds in accordance with the applicable piping design and welding procedure.
Slip-on flanges provide straightforward installation and alignment, making them a popular choice for many industrial piping systems.
The Class 150 designation represents an ASME pressure class rather than a maximum working pressure of exactly 150 PSI. Actual allowable pressure depends on material, flange size, temperature, and applicable pressure-temperature ratings.
Raised-Face Flange Construction
The raised-face (RF) design provides an elevated gasket seating area that concentrates bolting force over the gasket to help establish an effective seal.
ASME B16.5 establishes applicable flange dimensions, facing requirements, bolt patterns, tolerances, and pressure-temperature ratings.
Selecting an F304/L Slip On Flange
When ordering a Class 150 F304/L stainless steel slip-on raised-face flange, verify nominal pipe size, F304/F304L material, Class 150 rating, RF facing, ASME A/SA182 material specification, ASME B16.5 requirements, gasket, bolting, welding requirements, temperature, and process media.
