PN16 DN400 Flat Flange

Yes, the description you provided indicates the characteristics and advantages of a specific type of flange known as a weld neck flange. Weld neck flanges are commonly used in high-pressure and high/low-temperature applications where an unrestricted flow of fluid is required.The primary purpose of a weld neck flange is to provide a seamless transition between the pipe and the flange. The bore of the flange matches the bore of the pipe, effectively eliminating any obstructions or pressure drops that could lead to turbulence or erosion/corrosion of the metals near the flanged joints.The tapered hub of the weld neck flange plays a crucial role in distributing mechanical stress evenly between the pipe and the flange. This design feature promotes structural integrity and reduces the likelihood of leakage or welding defects. Additionally, the tapered hub facilitates radiographic inspections, allowing for easier detection of possible leakages and welding imperfections.It's important to ensure that the dimensions of the weld neck flange, such as NPS (Nominal Pipe Size) and the pipe schedule, match the dimensions of the connecting pipe. This ensures a proper fit and secure connection between the flange and the pipe.In summary, weld neck flanges are utilized in high-pressure and high/low-temperature applications to maintain an unrestricted flow of fluid, minimize pressure drops, prevent metal erosion/corrosion, distribute mechanical stress effectively, enable radiographic inspections, and ensure compatibility with the connecting pipe's dimensions.
