| ❌ Mistake | ✅ Correct Approach |
|---|---|
| Using incorrect pipe schedule for the intended pressure rating. | Always consult the design specifications and relevant pressure/temperature charts to select the appropriate pipe schedule (e.g., Schedule 80) that meets or exceeds service requirements. |
| Failure to properly prepare pipe ends for connection. | Ensure pipe ends are square, clean, and accurately beveled according to the chosen joining method (welding, threading) to guarantee a sound and leak-proof joint. |
