   EN1092-1 F316 PN16 RF Socket Weld Flange is a molybdenum-containing anti-corrosion small-bore pipe fitting developed for general chemical corrosive working conditions. Different from 304 series flanges, the added molybdenum element greatly enhances resistance to chloride ion, weak acid and brine medium erosion, solving the common pitting corrosion problem of ordinary stainless steel flanges in chemical workshops. PN16 medium pressure rating adapts to conventional chemical process pipeline transmission requirements.
The integral forged socket structure has high structural strength and excellent fatigue resistance, suitable for frequent pressure fluctuation of chemical pipelines. The precise smooth socket inner wall reduces corrosive medium residue, lowers crevice corrosion risk, and avoids local corrosion failure of pipe joints. Professional acid pickling and passivation treatment forms a dense anti-corrosion layer on the surface, stably resisting mild chemical medium erosion for a long time.
Core Selling Points
  1. Molybdenum alloy component, strong resistance to chloride pitting and salt water corrosion;

  2. EN European standard full compliance, fully interchangeable with EU chemical pipe fittings;

  3. Smooth socket inner wall without dead angle, easy pipeline flushing and maintenance;

  4. High fatigue resistance structure, adapt to chemical pipeline frequent pressure fluctuation;

  5. Stable sealing performance for weak acid and alkaline corrosive media;

  6. Small-bore precise welding structure, low leakage rate of chemical dangerous media.
