PN Flanges
PN Flanges are widely used in industrial piping systems where pressure ratings are defined by the PN (Pressure Nominal) classification. These flanges provide secure, leak-proof connections for pipes, valves, pumps, and other equipment, ensuring reliable performance under varying pressure conditions. PN Flanges are commonly manufactured according to EN, DIN, and ISO standards and are widely used across European and international industries.
At Royal Steel India, we manufacture and supply premium-quality PN Flanges in a wide range of sizes, pressure ratings, materials, and international standards. Our flanges are precision-engineered to deliver superior strength, corrosion resistance, and long-lasting performance for demanding industrial applications.
PN Flanges are pipe flanges classified according to their Nominal Pressure (PN) rating, which indicates the maximum pressure the flange is designed to withstand under specified operating conditions. Common pressure ratings include PN6, PN10, PN16, PN25, PN40, PN63, PN100, and PN160.
These flanges are available in various designs such as Weld Neck, Slip-On, Blind, Threaded, Socket Weld, Plate, and Lap Joint Flanges, making them suitable for a wide variety of industrial piping systems.
