What is a weld neck(WN) flange?
ASTM A105 welding neck flanges inclusing ASME B16.5 WN flanges and ANSI B16.47 WN flanges.
Weld neck flange (WN flange RF) is the most popular flange type, there is a neck extension with a weld bevel at the end. The WN flange is designed to butt weld to a pipe end directly, to provide a superior and relatively natural form connection. In larger sizes and higher pressure classes, this is almost exclusively the type of flange connection utilized.
The V-type bevel end joints to the pipe end ensure the uniform cirucular weld,resulting in a unifield transition. It allows the pipeline gas or liquids flow through the flanges by the minimum limit. The welded bevel should be inspected after welding to ensure the seal is uniform and normal.
Another special feature for welding neck flange is tapered hub. This type of flanges make the pressure force gradually distribute from the pipe to the base of flanges,thus help it withstand the impacts from use under the working environment with higher pressure and temperature. The mechanical stress would be limited cause of the extra steel material of tapered hub.
The higher pressure classes almost totally need this type of flanges connection,so the weld neck flanges usually made with sealing face of ring type joint (RTJ). This kind of sealing face allow the metal gaskets impressed in the grooves between two connected flanges,in order to form superior sealing. So welding neck flange with RTJ face is the main choice for pipeline application.
