Types of ANSI B16.5 Welding Neck Flanges

Flange Type	Description
Standard Welding Neck Flanges	These are the most common type, featuring a long tapered hub that provides excellent stress distribution. Ideal for high-pressure and high-temperature pipelines.
Reducing Welding Neck Flanges	Used to connect pipes of different diameters, these flanges maintain the strength and integrity of a standard weld neck flange while allowing for pipe size reduction.
Integral Welding Neck Flanges	These flanges are manufactured as an integral part of equipment or valves and provide a strong, leak-proof connection ideal for severe service conditions.
Long Neck Welding Flanges	Characterized by a longer neck than standard WN flanges, they are often used in vessel nozzles or heat exchangers to provide reinforcement and ease of connection.
Custom Welding Neck Flanges	Tailored to specific project needs, these flanges can be produced with special materials, dimensions, and facing types to meet challenging application requirements.
