The ASME B16.5 Weld Neck Flange is a welding-type flange cast or forged integrally with the tapered neck. It is then buttwelded to the piping system. The ASTM A182 SS WNRF Flange is made of austenitic steel consisting of 18% chromium and 8% nickel, and it is this composition that makes the flange strong and highly resistive to corrosion.
A weld neck flange is a type of flange that connects, seals, and changes the direction of a pipe in a pipe system by butt-welding the flange to the pipe. The neck of the weld neck flange matches the outer diameter of the pipe, providing a good welding interface during welding to ensure the strength and tightness of the connection.
The difference between ASME/ANSI and API
Weld Neck Flanges are a very common type of pipe flanges used in various industrial applications. They have a long tapered hub and are often used for high pressure applications.

What is a Weld Neck Flange and its 2 different shapes
The smooth transition between the flange and the hub combined with the strength of the butt weld joint, allows the flange to be used in extreme conditions of cyclic loading, bending and temperature fluctuations.

What is a weld neck flange and what about its dimensions?
A weld neck flange, also called a tapered hub flange or high-hub flange, is a kind of flange that can relocate stress to the pipes, ensuring a decrease in high-stress concentration at the bottom of the flange.
