PN16 DN150 Flat Flange

It appears that the flange you are describing is a weld neck flange. Weld neck flanges are commonly used in high-pressure and high/low temperature applications where there is a need for an unrestricted flow of fluid in the piping system. The bore of the weld neck flange matches the bore of the pipe, ensuring smooth flow and preventing pressure drops. This design helps to prevent negative effects such as turbulence and erosion/corrosion of the metals near the flanged joints.The tapered hub of the weld neck flange allows for a smooth distribution of mechanical stress between the pipe and the flange. This design also facilitates the execution of radiographic inspections to detect potential leakages and welding defects.It is important to ensure that the dimensions of the weld neck flange, such as the Nominal Pipe Size (NPS) and pipe schedule, match the dimensions of the connecting pipe for proper fit and function.
