Flange Configuration
Tapered Hub
The long tapered neck gradually transfers piping stress into the flange body, helping reduce stress concentration at the connection.
Butt-Weld Connection
The weld neck is designed to be butt welded directly to compatible pipe for a strong, permanent piping connection.
Raised Face
The raised sealing surface provides a defined gasket seating area for dependable bolted flange assembly.
Construction Details
The flange is manufactured from Type 316 stainless steel for excellent durability and corrosion resistance in aggressive service environments.
The tapered weld neck is designed to align with the pipe bore and create a smooth transition through the joint, helping reduce turbulence and localized stress.
The precision-machined raised face supports uniform gasket compression when paired with a compatible mating flange, gasket, and properly installed bolting.
Why Choose a Weld Neck Flange?
High-Strength Connection
- Butt welded directly to pipe
- Provides a permanent joint
- Tapered hub distributes piping stress
- Suitable for demanding piping service
- Designed for long-term structural integrity
Smooth Flow Transition
- Bore aligns with connected pipe
- Helps minimize turbulence
- Reduces abrupt internal transitions
- Useful in process piping systems
- Supports efficient fluid movement
316 Stainless Steel Construction
Corrosion Resistance
316 stainless steel provides strong resistance to corrosion, including improved performance in many chloride-containing and chemically aggressive environments.
Demanding Service
The material is well suited for many compatible marine, chemical, pharmaceutical, food processing, and industrial piping applications.
Raised Face Design
Focused Gasket Compression
The raised face concentrates gasket loading around the flange sealing area to help provide a dependable bolted joint.
Proper Gasket Selection
Select a gasket that matches the flange face, system media, pressure, temperature, and applicable piping specification.
Typical Applications
Industrial & Process Systems
- Chemical processing
- Process piping
- Industrial utility systems
- Equipment connections
- High-pressure piping
Specialty Environments
- Marine systems
- Pharmaceutical processing
- Food processing
- Corrosive environments
- Compatible high-temperature service
Weld Neck vs. Slip-On Flange
Weld Neck Flange
A weld neck flange uses a tapered hub and butt-weld connection to provide a strong, gradual transition from pipe to flange.
Slip-On Flange
A slip-on flange slides over the pipe and is typically secured with fillet welds, making alignment easier but using a different structural connection design.

Our valve, fitting, and industrial product specialists can help review your valve size, FIP connection requirements, pressure rating, handle configuration, media compatibility, and application before you order.

What type of flange is this?
This is a 316 stainless steel raised face weld neck flange.
What material is the flange made from?
The supplied product information identifies Type 316 stainless steel construction.
What does weld neck mean?
A weld neck flange has a tapered hub that is butt welded directly to the pipe to create a strong permanent connection.
What does RF mean?
RF means raised face, referring to the elevated gasket sealing area on the flange face.
How is the flange connected to pipe?
The weld neck is designed for butt welding directly to compatible pipe.
Why use a tapered hub?
The tapered hub helps transfer stress gradually between the pipe and flange rather than concentrating it at a sudden change in geometry.
Why choose 316 stainless steel?
316 stainless steel provides excellent corrosion resistance and is commonly used in demanding marine, chemical, process, and specialty piping environments.
Is a gasket required?
Yes. Use a compatible gasket between the raised face and mating flange.
What applications are these flanges suited for?
The supplied product information identifies chemical processing, marine, food processing, pharmaceutical, industrial, and demanding pressure piping applications.
What should I verify before ordering?
Confirm nominal flange size, pipe schedule or bore requirements, pressure class, raised face configuration, material compatibility, and applicable piping standard before ordering.
Important Ordering & Installation Notes
- This listing is for Midland 316 Stainless Steel Raised Face Weld Neck Flanges.
- Confirm the required nominal flange size before ordering.
- Verify the required pressure class and mating flange dimensions.
- Confirm pipe schedule or bore compatibility with the intended piping system.
- Verify raised face compatibility with the mating flange.
- Select a gasket compatible with the media, pressure, temperature, and flange faces.
- Verify 316 stainless steel compatibility with the intended service environment.
- Use qualified butt-welding procedures appropriate for the piping specification.
- Ensure proper pipe-to-flange alignment before welding.
- Inspect the completed weld according to applicable project and piping requirements.
- Use compatible flange bolts, nuts, and washers.
- Tighten bolting using the recommended cross-pattern sequence and torque procedure.
- Do not use flange bolts to force severely misaligned piping into position.
- Verify system pressure and temperature requirements before placing the connection into service.
- Install according to applicable piping standards, project requirements, and manufacturer recommendations.
