Description
304 Stainless Steel 300# Slip-On Raised Face Flange
304 Stainless Steel Class 300 Slip-On Raised Face Flanges provide a durable, corrosion-resistant connection for industrial and commercial piping systems. Manufactured from ASTM A/SA182 F304/L forged stainless steel, these flanges are designed to slip over the outside diameter of pipe for alignment before welding, creating a secure flanged connection with dependable sealing performance.
Designed to conform to ASME B16.5 dimensional standards, each slip-on flange features a precision-machined Raised Face (RF) sealing surface for use with compatible Class 300 raised face flanges and gaskets. The slip-on design allows the pipe to pass through the flange bore before fillet welding, making alignment and installation straightforward for a wide range of process piping applications.

Construction Details
These slip-on flanges are forged from ASTM A/SA182 F304/L stainless steel for strength, durability, and corrosion resistance in demanding piping environments.
The flange bore is sized so the flange can slide over the outside diameter of compatible pipe. The pipe is positioned within the flange and typically secured with fillet welds at the hub and pipe end in accordance with the applicable piping design and welding procedure.
The raised face sealing surface is precision machined to applicable ASME B16.5 dimensional requirements to provide a dependable gasket seating surface when installed with compatible Class 300 raised face flange components.

How a Slip-On Flange Works
A slip-on flange has a bore larger than the outside diameter of the mating pipe, allowing the flange to slide over the pipe before welding. This makes it possible to position and align the flange with the piping system before the connection is permanently secured.
After the flange is positioned, the pipe and flange are joined by appropriate fillet welds in accordance with the piping design, welding procedure, and applicable code requirements. A gasket is then positioned between the raised sealing faces, and the flange assembly is secured with appropriate bolting.
This configuration provides a practical bolted connection for many industrial and commercial piping applications while maintaining the corrosion resistance of forged 304/L stainless steel.
Raised Face Flange Design
The Raised Face (RF) configuration concentrates the gasket sealing area on the machined raised portion of the flange face. When the flange is properly assembled with a compatible gasket and mating raised face flange, bolt loading compresses the gasket between the sealing surfaces.
Always confirm that the mating flange, gasket, bolting, pipe, and associated components are compatible with the flange size, pressure class, material, service conditions, and applicable piping-system requirements.
Installation Considerations
- Confirm the correct nominal pipe size before installation.
- Verify that the mating flange is an appropriate Class 300 raised face flange.
- Confirm the pipe outside diameter is compatible with the flange bore.
- Position and align the flange before welding.
- Use a qualified welding procedure appropriate for the material and piping system.
- Select a gasket suitable for the flange configuration and piping service.
- Use appropriate flange bolts, studs, nuts, and related hardware.
- Confirm material compatibility with the process fluid and operating environment.
- Verify applicable pressure and temperature requirements before installation.
- Inspect flange sealing surfaces for damage, contamination, or irregularities before assembly.
- Properly align mating flanges before tightening the bolting.
- Follow appropriate flange-bolting and gasket-installation procedures.
- Installation and welding should be performed by qualified personnel familiar with flanged piping systems.
Product Selection Considerations
Size & Pressure Class
Confirm the required nominal pipe size and Class 300 flange designation before ordering. The mating flange, pipe, gasket, bolting, and associated components must be compatible with the selected slip-on flange.
Material & Service Conditions
Confirm that ASTM A/SA182 F304/L stainless steel is suitable for the process fluid, operating environment, pressure, temperature, and applicable piping-system requirements.
