EN1092-1 Type 01 Slip-On flanges in P245GH and P250GH are the European standard for pressure-bearing carbon steel systems. These grades are high-temperature structural steels with excellent weldability and toughness. Designed for PN25 and PN40 pressure ratings, they feature a flat plate design that slides over the pipe for double fillet welding. These flanges are vital in European boiler, heat exchanger, and power plant construction, ensuring safety and compliance with the Pressure Equipment Directive (PED)
