Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect welding consumables for 316 stainless steel.Employ AWS ER316L or E316L welding consumables to maintain the corrosion resistance of the base material.
Inadequate post-weld cleaning and passivation.Thoroughly clean welds and surrounding areas after fabrication, followed by passivation to restore the protective oxide layer and prevent surface corrosion.

Common Applications

  • Chemical Processing Plants
  • Offshore Oil and Gas
  • Marine and Seawater Applications

⚠️ Engineering Warnings

  • Verify chemical compatibility of the 316 stainless steel with the intended fluid medium.
  • Adhere strictly to relevant piping codes (e.g., ASME B31.3) for design, fabrication, and inspection.
