What is Power Tong Operation

Designed to improve the efficiency, and safety of drill floor operations, power tongs are essential tools in the oil and gas industry. They are large-capacity, self-locking wrenches used for applying torque, and gripping drill string components.

The torque needed to make up the casing thread is monitored, and controlled in order to ensure that the casing thread does not leak. It makes a rotating motion when breaking out, or making up casings, tubings, drill pipes, and other pipes. The make-up torque ratings rely on casing size, grade, metallurgy, weight, and the thread compound friction factor being utilized.
