Weld neck flanges according to EN 1092-1 PN 63 are designed for very high-pressure piping systems, ensuring robust, leak-proof connections through butt welding. The long tapered hub enhances strength and distributes stress evenly, making these flanges ideal for demanding environments. Manufactured to strict EN 1092-1 standards, they are commonly used in industries such as oil & gas, power generation, and chemical processing where high performance and durability are essential.
