EN1092-1 Weld Neck Flanges are forged carbon steel piping components, manufactured in strict compliance with European EN1092-1 standard (PN Series), tailored for industrial piping systems in EU countries, the Middle East, and other regions that adopt European standards. Made from high-quality carbon steel, these flanges ensure reliable butt-weld connection, perfect dimensional compatibility, and meet the strict quality requirements of European industrial projects.
With a long tapered hub and precision machining, these flanges are widely used in European oil & gas, chemical, power, and water treatment industries, providing stable performance and full compliance with EU industrial norms, making them a mainstream choice for European market buyers.
