Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incorrect welding procedures for 304 stainless steel.Employ TIG or MIG welding with appropriate filler material (e.g., 308L) and a controlled heat input to prevent sensitization and maintain corrosion resistance.
Inadequate support spacing for high-pressure applications.Calculate and install pipe supports based on fluid weight, pressure, and thermal expansion to prevent sagging and stress concentrations.

Common Applications

  • High-pressure chemical processing lines
  • Corrosive fluid transport in refineries
  • Sterile processing in food and beverage manufacturing

⚠️ Engineering Warnings

  • Verify compatibility with specific media and operating temperatures before installation.
  • Always adhere to local codes and regulations for pressure piping systems.
