Le terme "Iron Roughneck" dans l'industrie pétrolière et gazière désigne un équipement puissant et polyvalent utilisé à la fois pour les opérations de forage et d'achèvement de puits. Il s'agit essentiellement d'un **dispositif de connexion de tuyauterie** qui se trouve sur le plancher du derrick ou est suspendu juste au-dessus. Sa conception unique combine la fonctionnalité des **tongs de tête et de maintien** avec une **table tournante intégrée**, ce qui en fait un véritable cheval de bataille sur le derrick de forage.

Scenario: A drilling crew is preparing to run casing into the wellbore. They will be using an Iron Roughneck to connect the casing sections.
Task: Describe the steps involved in using an Iron Roughneck to connect two casing sections. Be sure to mention the roles of the lead and backup tongs, and the importance of the spinning table.
The steps for connecting two casing sections using an Iron Roughneck are: 1. **Prepare the Connection:** Align the two casing sections, ensuring the threads are clean and free from debris. 2. **Lead Tongs Engage:** The lead tongs grip the top joint of the casing, starting the connection process. 3. **Backup Tongs Engage:** The backup tongs grip the bottom joint, providing added security and preventing slippage during make-up. 4. **Spinning Table Activates:** The spinning table begins rotating the top joint, ensuring uniform thread engagement. 5. **Make-up to Full Connection:** The lead tongs continue to turn the top joint, gradually screwing it into the bottom joint, while the spinning table rotates to ensure even thread engagement. 6. **Final Tightening and Release:** Once the connection is fully made, the lead tongs provide a final tightening torque. The backup tongs are released, followed by the lead tongs, leaving the connected casing securely in place.
