Threaded Flange Design
Threaded flanges provide a mechanical pipe connection without requiring welding. The threaded bore allows compatible threaded pipe to be installed directly into the flange, making this style useful for systems where welding is impractical, undesirable, or not permitted.
Proper thread engagement, thread condition, sealing method, and system compatibility should be verified before installation.
Raised Face Sealing Surface
The raised face concentrates gasket loading over a smaller sealing area than a flat-face configuration. When paired with the correct mating flange, gasket, bolt pattern, and installation procedure, the raised face supports dependable sealing in compatible Class 150 flange systems.
304L vs. 316L Stainless Steel
304L Stainless Steel
- Strong general-purpose corrosion resistance
- Commonly used in commercial and industrial piping
- Suitable for many food, water, and process applications
- Low-carbon grade supports compatible fabrication requirements
316L Stainless Steel
- Enhanced corrosion resistance for more demanding environments
- Well suited for marine and chloride-exposed applications
- Commonly selected for chemical and process piping
- Useful where additional corrosion resistance is required
Forged Stainless Steel Construction
These flanges are manufactured from forged stainless steel materials conforming to ASME A182 requirements. Forged construction provides mechanical strength, dimensional consistency, and durability for demanding piping applications.
The flange dimensions conform to ASME B16.5 for compatibility with applicable Class 150 flange systems.

Frequently Asked Questions
What does RF mean on a threaded flange?
RF means Raised Face. The gasket sealing surface is raised above the surrounding flange face to concentrate gasket loading in compatible flange assemblies.
What pressure class are these flanges?
These are Class 150, commonly referred to as 150# stainless steel flanges.
What stainless steel grades are available?
These threaded raised face flanges are available in 304L and 316L stainless steel grades.
Do threaded flanges require welding?
No. The threaded bore is designed to connect to compatible threaded pipe without welding.
What material standard do these flanges conform to?
The forged stainless steel material conforms to ASME A182 requirements.
What dimensional standard is used?
The flange dimensions conform to ASME B16.5.
What is the difference between 304L and 316L stainless steel?
Both provide corrosion resistance, but 316L is generally selected for more aggressive environments, including many marine, chloride, and chemical-processing applications.
Can these flanges be used with any Class 150 flange?
Compatibility depends on nominal size, flange face, dimensions, gasket type, bolting, material, pressure, temperature, and system requirements. Confirm all mating components before installation.
Where can I find flange dimensions?
Use the Stainless Steel ANSI Flange Dimensions PDF in the product support section above to review dimensional information.
What applications are these threaded flanges commonly used for?
Common applications include industrial piping, commercial plumbing, chemical processing, food service, marine systems, water treatment, and general process piping.
