DIN 25 BAR Flanges (PN25) – High-Pressure DIN Standard Flanges
DIN 25 BAR flanges, commonly designated as PN25 flanges, are pressure-rated to handle up to 25 bar (362 psi), making them suitable for medium to high-pressure industrial applications. These flanges are designed according to DIN (Deutsches Institut für Normung) specifications and are critical in ensuring leak-proof connections in pressurized pipeline systems. Werner Flanges Inc. produces and supplies DIN 25 BAR flanges with precision machining and superior quality assurance standards.
DIN 25 BAR flanges are widely used in power generation, water treatment, high-pressure steam systems, petrochemical plants, and industrial manufacturing. These flanges are ideal for projects requiring secure sealing under elevated pressure conditions and are compatible with international piping systems where PN25 ratings are needed.
Werner Flanges Inc. offers DIN 25 BAR flanges in a wide range of sizes (DN10 to DN600), face types (RF, FF), and finishes. Customers can choose from various types like slip-on, weld neck, blind, and socket weld, available in carbon steel, stainless steel, and alloy steel options. We ensure rapid dispatch from global warehouses and tailor materials and coatings to suit specific project needs.
Werner Flanges Inc. is a globally recognized manufacturer and exporter of DIN-standard flanges.
