Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect welding consumables for 304 stainless steel, leading to compromised weld integrity and corrosion resistance.Always employ welding rods and filler materials specifically designed for 304 stainless steel, such as ER308L.
Inadequate pipe support leading to stress concentrations and potential failure.Install pipe supports at recommended intervals to distribute weight and prevent excessive sagging or vibration.

Common Applications

  • Chemical processing pipelines
  • Food and beverage sanitary systems
  • High-purity water and gas distribution

⚠️ Engineering Warnings

  • Avoid exposure to high concentrations of hydrochloric or sulfuric acids at elevated temperatures, as this can lead to pitting corrosion.
  • Ensure proper passivation after welding to restore the full corrosion resistance of the material.
