Note: - Diameter refers to the outside diameter of tubing and casing, master tong clamps the pipe body, and backup tong clamps the coupling in making-up and breaking-out operation. - Both master tong and backup tong clamp the drilling pipe joint. The outside diameter of the drilling pipe refers to the outside diameter of the joint. - Use prolonged guide pole, select die seats and dies according to the actual diameter of pipe body to be clamped when backup tong clamps the body of the pipe. - It is not suitable for the pipe string with surface hardness degree≥340HB. - Special die seat and dies can be custom-made. |
