Break Out Torque EUE Connections

[Hanyahmed]

What is the maximum torque for break out (POOH) that the pipes body material could withstand before being collapsed by the hydraulic tong.

- String : 3 ½” EUE L-80, weight 9.2 (Pipes in the well years ago)

Hi Hanyah,
3 ½” EUE L-80, weight 9.2 make up torque is 3130 lbf/ft. to break will require more than 3130. 3000 psi of clamping can collapse the tubing
