Welding Neck (WN) FlangeThe Welding Neck (WN) Flange is a flange designed to be welded to a pipe. The flange has a long tapered hub that is welded to the pipe to form a strong, leak-free connection. The flange also has a flat circular plate with bolt holes to secure the flange to another flange or piece of equipment.
Description
A Welding Neck (WN) Flange is a type of flange used in piping systems to connect pipes and equipment together. It is designed to be welded to the pipe or fitting and then bolted to another flange or piece of equipment. The WN flange has a long tapered neck that is welded to the pipe or fitting, and a flat face that extends out from the neck. The flat face of the flange provides a surface for the gasket to seal against, and the bolts are tightened to compress the gasket and create a leak-tight seal. The neck of the WN flange also provides reinforcement to the connection, which makes it suitable for use in high-pressure and high-temperature applications. The tapered design of the neck reduces stress concentrations and distributes the load evenly across the flange, which helps to prevent leaks and failures.

A welding neck flange (WN) features a long tapered hub that can be welded with a pipe. This flange type is used, normally, in high-pressure and high/low temperatures applications that require an unrestricted flow of the fluid conveyed by the piping system (the bore of the flange matches with the bore of the pipe). The absence of pressure drops prevents negative effects as turbulence and erosion/corrosion of the metals in the proximity of the flanged joints. The tapered hub allows a smooth distribution of the mechanical stress between the pipe and the weld neck flange and facilitates the execution of radiographic inspections to detect possible leakages and welding defects. The dimension of the flange (NPS and the pipe schedule) shall match the dimension of the connecting pipe.
