Features of Ansi B16.5 Socket Welding Flanges

Design and Construction

Socket weld flanges have a precise machine-designed socket, or recess, for a pipe end. Usually, socket depth is 1.25 pipe wall thickness and provides optimum welding condition and joint strength.

Pressure and Temperature Ratings

These flanges are manufactured to various pressure class ratings, typically from Class 150 through Class 1500.

ANSI B16.5 Class150 SOCKED WELDING FLANGES

Welding Characteristics

Socket weld flanges are designed for weldability and machined for a specific socket depth, allowing proper heat distribution during welding. The welding procedure involves welding a fillet weld around the circumference of the pipe at the socket opening.

Safety Characteristics

Socket weld flanges have a number of features that enhance safety. The welded joint eliminates the chance of mechanical loosening, which can occur in threaded connections, thus offering better safety for high-vibration applications.

Types of Ansi B16.5 Socked Welding Flanges

01/

Raised Face (RF) Socket Weld Flanges
Raised Face (RF) Socket Weld Flanges have a raised flange bore on the face with the gasket sitting on the raised surface. This design improves the sealing performance suitable for medium- to high-pressure applications.

02/

Flat Face (FF) Socket Weld Flanges
FF Socket Weld Flanges have a flange face surface that is normally a flat gasket surface. This design is suitable for use on equipment that is metallic cast iron, and so on, or other materials that you do not want to damage when joining.

03/

Ring-Type Joint (RTJ) Socket Weld Flanges
Ring-Type Joint (RTJ) Socket Weld Flanges with a precision machined groove to hold metal ring gasket to provide a metal-to-metal seal. The resistance to leakage under high-pressure and high-temperature is superior to other designs.

04/

Reducing Socket Weld Flanges
Reducing Socket welding Flanges are intended to join pipes with different diameters. Through a smaller socket bore, these components eliminate the need for additional reducers, simplifying the pipeline layout and lowering installation costs.

FAQ

Q: What is the ASME standard for socket weld flanges?

A: ASME B16.5 standard
Socket weld flanges are available in various sizes and dimensions, as per the ASME B16. 5 standard. The dimensions for socket weld flanges are specified in this standard, with sizes ranging from 1/2″ to 3″. The flanges are available in various pressure classes, ranging from 150 to 2500.

Q: What is the ANSI B16 5 flange?

A: B16. 5 is limited to flanges and flanged fittings made from cast or forged materials, and blind flanges and certain reducing flanges made from cast, forged, or plate materials. Also included in this Standard are requirements and recommendations regarding flange bolting, flange gaskets, and flange joints.

Q: What is the difference between ASME B16 5 and ANSI B16 5?

A: Understanding the key differences between ANSI B16. 5 and ASME B16. 5 flanges is crucial for the right project selection. ANSI flanges are great for standard uses, while ASME flanges suit more critical applications.

Q: What is the gap on a socket weld flange?

A: The ASME B31. 3 standard states that an approximate gap of 1⁄16th of an inch (1.5mm) between the socket and pipe end is required; this gap allows for thermal expansion due to welding and reduces the likelihood that the weld will crack.

Q: Do socket weld flanges have a schedule?

A: Socket Weld Flanges are available in pressure from 150# and up and pipe schedule 40 to schedule 160. Specifying the pipe schedule ensures that ID of the SW Flange matches the ID of pipe for smooth fluid flow.
