1. Product Description 
A Weld Neck Flange is a type of pipe flange characterized by a long, tapered hub that is gradually welded to a pipe through a butt weld (a type of circumferential butt weld) . This design is integral for high-integrity applications. It is typically manufactured from forged steel for superior strength and is designed to handle high-pressure environments, typically ranging from 1 MPa to 25 MPa . The flange is part of two main international standard systems: the European system (PN series) and the American system (Class series) .
 
2. Key Product Parameters 
Parameter Details
Types & Codes Weld Neck Flange (WN)
Applicable Standards HG/T 20592-2009 (European PN Series), HG/T 20615-2009 (American Class Series), GB/T 9115-2010, JB/T 82-94
Nominal Diameter (DN) Wide range available, commonly from DN10 upwards
Pressure Ratings European System (PN): PN10 to PN250 . American System (Class): Class 150 to Class 2500 .
Sealing Face Types Raised Face (RF), Male-Female (MFM), Tongue-Groove (TG), Ring Joint (RJ) . The RJ face is often used for pressures above PN160/Class 600 .
Common Materials Carbon Steel, Stainless Steel (304, 304L, 316, 316L, 321), Alloy Steels (Chrome-Molybdenum, Chrome-Molybdenum-Vanadium) .
Manufacturing Process Forging .
 
3. Product Applications 
Weld Neck Flanges are designed for demanding services and are widely used in:
High-Pressure and High-Temperature Pipelines .
Pipelines transporting flammable, explosive, or toxic media .
Applications with significant temperature or pressure fluctuations .
Critical industries such as Petroleum & Gas, Chemical Processing, Pharmaceutical, and Shipbuilding .
 
4. Product Advantages 
Excellent Strength and Stress Distribution: The long, tapered hub provides a smooth transition from the pipe to the flange, significantly reducing stress concentration and increasing the flange's rigidity and resistance to deformation .
Superior Sealing Performance: Robust construction and various sealing face options make it ideal for maintaining a leak-tight seal in severe service conditions .
High-Integrity Connection: The butt weld connection offers a full penetration weld, which has higher fatigue strength and is more reliable than fillet welds, making it suitable for applications with vibration and bending moments .
Durability: Can withstand high pressure (up to ~25 MPa), high temperature, and repeated cycling
