DIN2501 hot dip galvanized plate flange, PN16 galvanized flat flange, EU fire fighting plate flange

   DIN2501 PN16 Hot Dip Galvanized Plate Flange is European standard hot galvanized flat welding flange complied with German DIN2501 industrial standard, specially customized for European local fire protection, outdoor drainage and municipal plumbing projects. The base material adopts high-quality S235JR European standard carbon steel, with stable tensile strength and welding performance, matching full set of DIN standard pipe fittings, valves and fasteners without secondary modification on construction site.

   The whole flange adopts high-temperature hot dip galvanizing anti-rust process instead of electric galvanizing, average zinc layer thickness reaches 85μm, forming thick zinc alloy protective layer on flange surface, bolt hole inner wall and sealing edge. The integrated zinc layer can resist rain erosion, humid air oxidation, soil mild corrosion, adapting long-term outdoor buried and exposed pipeline working environment. Standard PN16 pressure grade meets European municipal 1.6MPa conventional pipeline load requirement, RF raised face fits European standard rubber fire-proof gasket, stable fire pipeline sealing performance.

   We strictly follow German dimensional tolerance standard for machining, unified DIN bolt hole spacing and flange outer diameter, high interchangeability for old European pipeline renovation projects. Before galvanizing, every flange is shot blasted to remove surface oxide skin, enhancing zinc layer adhesion to avoid peeling and shedding. Size range DN15-DN700, full DIN size in stock. Adopt outer and inner fillet welding installation, easy for European construction team operation. Suitable for building fire sprinkler pipe, outdoor buried drainage pipe, European park water supply system. Provide fumigated wooden export package, 15-month outdoor anti-rust warranty, batch preferential price for EU engineering contractors.
