Class 150 F316/L Stainless Steel Slip On, Raised-Face Flange
Class 150 F316/L Stainless Steel Slip On Raised-Face Flange
The Class 150 F316/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 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 F316/L Stainless Steel
ASTM A182 / ASME SA-182 F316/F316L stainless steel provides excellent mechanical strength, durability, and corrosion resistance. The molybdenum content in F316/F316L offers improved resistance to pitting and corrosion in many chloride-containing environments compared with F304 stainless steel.
The lower carbon content of F316L stainless steel helps minimize carbide precipitation during welding, supporting corrosion resistance in heat-affected areas of properly fabricated piping systems.
Class 150 Slip On Flange Design
A slip-on flange has a bore designed to slide over the outside diameter of compatible pipe. After proper positioning, the flange is typically secured using fillet welds in accordance with applicable piping codes, qualified welding procedures, and system requirements.
Class 150 F316/L slip-on flanges are widely used in chemical processing, pharmaceutical manufacturing, food and beverage production, water treatment, marine applications, utilities, manufacturing, and industrial process piping.
The Class 150 designation identifies an ASME pressure class rather than a maximum working pressure of exactly 150 PSI. Actual allowable pressure depends on material, flange size, operating temperature, and applicable pressure-temperature ratings.
Raised-Face Flange Construction
The raised-face (RF) design provides an elevated gasket seating area that concentrates bolting load over the gasket to help establish an effective seal.
ASME B16.5 establishes applicable flange dimensions, facing requirements, bolt-hole patterns, tolerances, and pressure-temperature ratings.
Selecting an F316/L Slip On Flange
When ordering, verify nominal pipe size, F316/F316L material, Class 150 rating, RF facing, ASME A/SA182 specification, ASME B16.5 requirements, gasket, bolting, welding requirements, temperature, process media, and corrosion requirements.
