Is Make-Up torque your limit?

On several occasion during my career, I had to fight the myth that the recommended make up torque is the maximum torque the drill pipe should see while drilling. Well, it’s a myth and I will show why. I’ll show you how make-up torque and any additional torque is transferred into tension and it is affecting tensile strength rating of the pipe. I’ll show you what is happening with the pin and box while torque is applied and how make-up torque is determined. Hope this will be an eye opener for you as it was for me when I learned it during one of the courses I attended as drilling engineer.
