| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incompatible joining methods (e.g., welding with incorrect filler material) that can compromise corrosion resistance. | Always use filler materials specifically recommended for 316 stainless steel and follow approved welding procedures to maintain material integrity. |
| Improperly cleaning pipe ends before connection, leading to leaks or reduced joint strength. | Thoroughly clean all pipe ends and fittings with a degreaser and ensure they are dry before assembly. |
