WELDIN NECK Flange (WN)

The WN flange according to ANSI (American National Standards Institute) standards is known as a Welding Neck flange (flange with a welding neck).
It is one of the most common and widely used types of flanges for high-pressure and high-temperature applications.

Characteristics of the WN Flange (Welding Neck):

• Tapered neck designed for butt welding directly to the pipe;
• High mechanical strength suitable for severe conditions;
• Stress reduction: thanks to the neck shape, which allows for optimal stress distribution;
• Commonly used in petrochemical plants, power plants, and high-pressure systems.
