Weld Neck Design
Tapered Hub
The long tapered hub provides a gradual transition between the flange and pipe, helping distribute mechanical stress over a larger area.
Butt-Weld Connection
The flange neck is designed to be butt welded directly to compatible pipe for a strong, permanent connection with excellent joint integrity.
Machined Sealing Face
A precision-machined flange face provides a consistent gasket seating surface for dependable sealing when properly matched and assembled.
Construction Details
Forged carbon steel construction provides the mechanical strength and durability required for demanding commercial and industrial piping systems.
The tapered weld neck helps reduce localized stress concentrations at the flange-to-pipe transition, improving resistance to fatigue caused by pressure fluctuations, vibration, and thermal cycling.
A full-penetration butt weld creates a continuous transition between the flange bore and connected pipe, helping provide strong joint integrity and efficient flow through the connection.

What is a weld neck flange?
A weld neck flange features a long tapered hub that is butt welded directly to the pipe, creating a strong permanent flange connection.
What material is this flange made from?
The supplied product information identifies forged carbon steel construction.
How does a weld neck flange connect to the pipe?
The flange is designed for a full-penetration butt weld between the flange neck and compatible pipe.
Why does a weld neck flange have a tapered hub?
The tapered hub gradually transfers stress from the flange into the pipe, helping reduce localized stress concentrations at the connection.
Is this flange suitable for high-pressure applications?
The supplied product information identifies the weld neck design as suitable for demanding high-pressure piping applications when the proper flange pressure class and system components are selected.
Can it be used for elevated-temperature service?
Yes, when the flange material, pressure class, connected piping, gasket, bolting, and other system components are properly selected for the intended operating conditions.
What should I verify before ordering?
Confirm nominal pipe size, pressure class, flange facing, pipe schedule or bore requirements, material, and compatibility with the connected piping system.
