| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using standard carbon steel pipe in corrosive environments. | Always specify 316 stainless steel for applications involving acids, chlorides, or saltwater to prevent premature failure and contamination. |
| Inadequate weld preparation leading to porosity or lack of fusion. | Thoroughly clean and prepare pipe ends, ensuring proper beveling and fit-up according to welding codes to achieve sound welds. |
