Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incompatible welding filler material for 304 stainless steel.Always use a filler metal specifically designed for 304 stainless steel, such as ER308L, to maintain corrosion resistance.
Inadequate support spacing for long pipe runs.Consult industry standards or manufacturer guidelines for appropriate support spacing to prevent sagging and stress concentrations.

Common Applications

  • Chemical Processing Pipelines
  • Food and Beverage Transfer Systems
  • High-Purity Water Systems

⚠️ Engineering Warnings

  • Ensure proper ventilation when welding or fabricating to avoid exposure to hazardous fumes.
  • Handle with care to prevent scratching or marring the surface finish, which can compromise corrosion resistance.
