Corrosion Resistance of Welded Pipes in Harsh Environments

Date:2025-03-12

Welded pipes exposed to acidic, saline, or high-temperature environments (such as chemical plants and marine applications) require specific material choices and coatings for optimal corrosion resistance.

  • Weld Material Selection: 316L and 2205 duplex steels offer superior corrosion resistance at welds compared to regular 304/304L steels in chloride-rich environments.
  • Passivation After Welding: Post-weld passivation (using nitric acid solutions) helps remove free iron on the weld zone, preventing crevice corrosion.
  • Weld Metal Strength: The strength of the weld area can be optimized using submerged arc welding (SAW) with low hydrogen electrodes to ensure both corrosion resistance and mechanical properties.
