EN1092-1 F316 PN16 RF Plate Flange is a molybdenum-containing anti-corrosion flat weld fitting developed for light chemical corrosive working conditions. Different from 304 series plate flanges, the added molybdenum alloy element greatly enhances resistance to chloride ion, weak acid and brine medium erosion, solving the common pitting corrosion failure problem of ordinary stainless steel flanges in chemical workshops. The PN16 medium-pressure rating fully meets the transmission requirements of conventional chemical process pipelines.
The integral stamped plate structure features uniform stress distribution and excellent structural stability, adapting to frequent pressure fluctuations of chemical pipelines. The finely polished flat sealing surface has no medium residue dead angles, reducing crevice corrosion risk and ensuring stable sealing of corrosive media. Professional chemical-grade pickling and passivation forms a dense anti-corrosion film on the surface, which can long-term resist mild acid, alkali and salt water medium scouring. Strictly implemented European standard dimensional specifications ensure full interchangeability with EU chemical pipeline fittings.
