Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect welding procedures for stainless steel.Employ GTAW (TIG) or SMAW (stick) with appropriate 308L filler material and controlled heat input to prevent sensitization and maintain corrosion resistance.
Contamination of the pipe interior or exterior during handling and installation.Store and handle the pipe in a clean environment, using non-marking tools and covers to prevent contamination that can lead to localized corrosion.

Common Applications

  • High-pressure hydraulic systems
  • Chemical and petrochemical processing
  • Food and beverage processing equipment

⚠️ Engineering Warnings

  • Ensure compatibility of fluid media with 304 stainless steel to prevent corrosion.
  • Adhere to all relevant industry codes and standards for pressure vessel and piping construction.
