Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using standard carbon steel fittings with 316 stainless steel pipe.Always use 316 stainless steel fittings and compatible welding consumables to maintain corrosion resistance and prevent galvanic corrosion.
Improper beveling for welding, leading to incomplete fusion.Ensure a consistent and correct bevel angle (typically 30-37.5 degrees) is achieved on the pipe ends to facilitate full weld penetration.

Common Applications

  • Chemical Processing and Petrochemical Industries
  • Marine and Offshore Fluid Transfer Systems
  • High-Purity Water Systems
  • Pharmaceutical Manufacturing
  • Food and Beverage Processing

⚠️ Engineering Warnings

  • Ensure compatibility with all conveyed fluids and environmental conditions. Consult material compatibility charts.
  • Proper welding procedures and post-weld heat treatment, if required by application, are critical for maintaining material integrity and corrosion resistance.
