Description
150# Stainless Steel RF Weld Neck Flange Sch10 Bore
150# Stainless Steel Raised Face Weld Neck Flanges with Schedule 10 Bore are designed for welded stainless steel piping systems requiring dependable flange strength, dimensional consistency, and corrosion resistance. The tapered weld neck provides a smooth transition from flange to pipe, helping distribute mechanical stress through the connection.
Manufactured from 304L or 316L forged stainless steel, these Class 150 flanges feature a Schedule 10 bore and raised face configuration. They are well suited for industrial, commercial, chemical processing, food processing, marine, water treatment, and general process piping applications.

Weld Neck Design
The weld neck design uses a tapered hub that transitions gradually from the flange body to the connected pipe. This configuration is commonly used where a strong welded connection and improved stress distribution are important.
The flange is intended to be butt welded to compatible pipe, creating a continuous welded connection between the pipe and flange hub.

Schedule 10 Bore
This flange is supplied with a Schedule 10 bore intended to match compatible Schedule 10 piping.
Always confirm nominal pipe size, actual pipe wall thickness, bore dimensions, and welding requirements before ordering or installation.
Raised Face Sealing Surface
The raised face provides the gasket sealing surface used in compatible bolted flange assemblies. The raised sealing area helps concentrate gasket loading when the flange is properly assembled with the correct mating flange, gasket, and bolting.
304L vs. 316L Stainless Steel
304L Stainless Steel
- Strong general-purpose corrosion resistance
- Commonly used in commercial and industrial piping
- Suitable for many water, food, and process applications
- Low-carbon grade commonly used in welded assemblies
316L Stainless Steel
- Enhanced corrosion resistance in demanding environments
- Commonly selected for marine and chloride-exposed service
- Suitable for many chemical and process piping applications
- Low-carbon grade commonly used in welded assemblies
Forged Stainless Steel Construction
These weld neck flanges are manufactured from forged stainless steel material conforming to ASME A182. Forged construction provides mechanical strength, durability, and dimensional consistency for demanding piping systems.
Flange dimensions conform to ASME B16.5 for applicable Class 150 flange systems.

Frequently Asked Questions
What is a weld neck flange?
A weld neck flange has a tapered hub designed to be butt welded directly to compatible pipe. The gradual transition helps distribute stress through the flange-to-pipe connection.
What does RF mean?
RF means Raised Face. The gasket sealing surface is raised above the surrounding flange face for use with compatible gasketed flange assemblies.
What pressure class is this flange?
This flange uses a 150# / Class 150 flange pattern.
What bore does this flange have?
This weld neck flange is supplied with a Schedule 10 bore.
What stainless steel grades are available?
These flanges are available in 304L and 316L stainless steel.
What is the difference between 304L and 316L?
Both provide corrosion resistance. 316L is generally selected for more demanding environments, including many marine, chloride-exposed, and chemical-processing applications.
What material standard applies?
The forged stainless steel material conforms to ASME A182.
What dimensional standard applies?
The forged stainless steel flange dimensions conform to ASME B16.5.
Can this flange be used with Schedule 40 pipe?
This listing is specifically for a Schedule 10 bore. Confirm the actual pipe wall thickness and bore compatibility before ordering or welding the flange to the pipe.
Where can I find flange dimensions?
Use the Stainless Steel ANSI Flange Dimensions PDF in the Product Documents section above to review dimensional information before ordering.
What applications are these flanges commonly used for?
Common applications include industrial piping, chemical processing, water treatment, food processing, marine systems, mechanical equipment connections, and general Schedule 10 stainless steel process piping.
