Hubbed Slip-On Flanges as per EN 1092-1 PN25 are precision-engineered flanges designed to slip over the pipe and be welded both internally and externally for secure, high-strength joints. The integrated hub provides additional mechanical support and alignment, enhancing durability under pressure. Compliant with the EN 1092-1 European standard, these flanges are rated for a nominal pressure of 25 bar (PN25), making them suitable for higher-pressure systems in industries such as petrochemical, steam lines, water treatment, and general process piping. They are available in a variety of materials, such as carbon steel and stainless steel, depending on the application.
