DIN Standard PN25 Weld Neck Pipe Flange

DIN Standard PN25 Weld Neck Pipe Flange Product Overview The DIN Standard PN25 Weld Neck Pipe Flange is a high-pressure German Industrial Standard (DIN) Standard pipeline flanges designed for demanding industrial piping systems, serving as a critical industrial pipeline connection flanges that provides a permanent, leak-proof connection between pipes, valves, and equipment. As a core member of the multi-standard pipe flanges family, this flange adheres strictly to DIN 2634 standards, ensuring compatibility with European and global industrial piping projects. Engineered for PN25 (25 bar) pressure rating, the DIN PN25 weld neck flange features a tapered hub that transitions smoothly from the pipe wall to the flange face, distributing stress evenly and eliminating stress concentration—making it ideal for high-pressure, high-temperature applications such as oil & gas, petrochemical, and power generation. The Raised Face (RF) sealing surface is designed for use with spiral wound or met…
