Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Incorrect pipe size or schedule selection for the intended pressure and temperature rating.Thoroughly review system design parameters and consult relevant piping codes to ensure the selected pipe meets all operational requirements.
Contamination of the 304 stainless steel during fabrication or installation.Implement stringent cleaning protocols, use dedicated tools, and avoid contact with carbon steel or other incompatible materials to maintain corrosion resistance.

Common Applications

  • High-pressure chemical processing lines
  • Corrosive fluid transfer in petrochemical plants
  • Critical fluid handling in pharmaceutical manufacturing

⚠️ Engineering Warnings

  • Ensure compatibility of the 304 stainless steel with the specific fluid media and operating temperatures to prevent corrosion or material degradation.
  • Always follow proper welding procedures and post-weld heat treatments, if applicable, to maintain the integrity and corrosion resistance of the pipe and its joints.
