| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incompatible welding consumables leading to reduced corrosion resistance. | Always use AWS ER316L or equivalent filler metals when welding 316 stainless steel to maintain optimal corrosion properties. |
| Improper support spacing leading to excessive pipe deflection or stress. | Consult ASME B31.3 guidelines for appropriate pipe support spacing based on pipe size, material, and operating conditions to prevent undue mechanical stress. |
