Description
150# Stainless Steel RF Socket Weld Flange
150# Stainless Steel Raised Face Socket Weld Flanges provide a strong, compact welded connection for stainless steel piping systems. The socket weld design allows pipe to be inserted into the recessed socket before welding around the hub, providing accurate alignment and a dependable connection for compatible piping systems.
Manufactured from forged stainless steel and available in 304L and 316L grades, these Class 150 flanges feature a raised face sealing surface and standard 150# bolt pattern. They are well suited for industrial, commercial, chemical processing, food processing, marine, water treatment, and general process piping applications.

Socket Weld Design
The socket weld connection allows compatible pipe to be inserted into a recessed socket in the flange before the connection is welded around the outside of the hub. This design helps position and align the pipe during assembly while providing a permanent welded connection.
Socket weld flanges are commonly selected for piping systems where a compact welded flange connection is preferred.
Raised Face & 150# Bolt Pattern
These flanges feature a Class 150 raised face configuration. The raised sealing surface concentrates gasket loading over the gasket contact area when assembled with a compatible mating flange and gasket.
Flange dimensions conform to ASME B16.5. Always verify nominal pipe size, bolt pattern, mating flange, gasket, bolting, and system requirements before installation.
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 stainless grade commonly used in welded assemblies
316L Stainless Steel
- Enhanced corrosion resistance for demanding environments
- Commonly selected for marine and chloride-exposed service
- Suitable for many chemical and process piping applications
- Low-carbon stainless grade commonly used in welded assemblies
Forged Stainless Steel Construction
These socket weld flanges are manufactured from forged stainless steel material conforming to ASME A182. Forged construction provides strength, durability, and dimensional consistency for demanding piping applications.
Flange dimensions conform to ASME B16.5, providing standardized dimensional requirements for applicable Class 150 flange systems.

Frequently Asked Questions
What is a socket weld flange?
A socket weld flange has a recessed socket that accepts the end of compatible pipe. The pipe and flange are then joined by welding around the outside of the flange hub.
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 connections.
What pressure class is this flange?
This is a Class 150 flange, commonly referred to as a 150# flange.
What stainless steel grades are available?
These socket weld flanges are available in 304L and 316L stainless steel.
What is the difference between 304L and 316L?
Both grades provide corrosion resistance. 316L is generally selected for more demanding environments, including many marine, chloride-exposed, and chemical-processing applications.
What material standard applies to these flanges?
The forged stainless steel material conforms to ASME A182.
What dimensional standard applies?
The forged stainless steel flange dimensions conform to ASME B16.5.
Does a socket weld flange require welding?
Yes. The pipe is inserted into the flange socket and the connection is completed with a weld around the outside of the hub.
Where can I find the flange dimensions?
Use the Stainless Steel ANSI Flange Dimensions PDF in the Product Documents section above to review dimensional information.
What applications are these flanges commonly used for?
Common applications include industrial piping, chemical processing, food processing, water treatment, marine systems, mechanical equipment connections, and general stainless steel process piping.
