A weld neck flange is a type of flange that is designed to be welded to a pipe. It has a long, tapered hub that gradually merges into the pipe, providing an even distribution of stress across the flange and the pipe. The weld neck flange is considered to be the most reliable and strongest type of flange, and is therefore commonly used in high-pressure and high-temperature applications.

The welding process used to attach the weld neck flange to the pipe involves first beveling the end of the pipe and then welding it to the tapered hub of the flange. This creates a strong and leak-proof connection, as the welding process fuses the two components together.

Weld neck flanges are available in a wide range of materials, including carbon steel, stainless steel, and various alloys. The choice of material will depend on the specific application and the requirements for strength, corrosion resistance, and other properties.

Weld neck flanges are commonly used in industries such as oil and gas, chemical processing, and power generation. They are also used in piping systems that are subject to thermal expansion and contraction, as the tapered hub allows for some movement without causing stress on the flange or the pipe.
