 F316L Low Carbon Molybdenum Marine Offshore Salt Fog High Pressure Pipeline Fitting F316L Low Carbon Molybdenum Marine Offshore Salt Fog High Pressure Pipeline Fitting F316L Low Carbon Molybdenum Marine Offshore Salt Fog High Pressure Pipeline Fitting F316L Low Carbon Molybdenum Marine Offshore Salt Fog High Pressure Pipeline Fitting

   EN1092-1 F316L PN25 RF Socket Weld Flange is a heavy-duty anti-corrosion and high-pressure resistant small-bore flange for marine and offshore engineering. Adopting low-carbon molybdenum stainless steel formula, it solves the welding intergranular corrosion and insufficient salt spray resistance of ordinary 316 flanges. PN25 (2.5MPa) medium-high pressure rating adapts to marine ballast water, fire protection and offshore platform process pipeline heavy-load working conditions.
Ultra-low carbon structure avoids weld embrittlement and cracking caused by long-term coastal salt fog erosion. Molybdenum alloy provides strong seawater and chloride corrosion resistance, passing 5000-hour neutral salt spray test. The thickened socket and flange body improve pressure resistance and structural rigidity, adapting to ship pipeline vibration and wave impact load. Enhanced super passivation treatment ensures long-term anti-rust performance in high-humidity and high-salt marine environments.
Core Selling Points
  1. Low carbon anti-weld cracking, eliminate marine salt fog welding corrosion failure;

  2. Molybdenum enhanced salt spray resistance, professional marine anti-corrosion grade;

  3. PN25 high pressure resistance, adapt to marine pipeline hydraulic impact;

  4. Reinforced socket structure, strong anti-vibration and anti-loosening performance;

  5. Pass professional marine salt spray test, stable for long-term offshore service;

  6. Small-bore compact structure, suitable for narrow cabin pipeline layout.
