Hydraulic Power Tongs

Definition - What does Hydraulic Power Tongs mean?

Hydraulic Power Tongs are a type of power tongs operated by a liquid which moves in a confined space under pressure. These tongs have a self locking mechanism and large capacity pliers used to grip drill string components so as to apply torque. They should be used by a plumber in opposing pairs with opposing pipe wrenches. To improve the efficiency, one set of the tongs is tied off with a chain or a cable to the derrick and another set is pulled actively with mechanical catheads.

Petropedia explains Hydraulic Power Tongs

Power Tongs are either hydraulically or pneumatically operated tools. Hydraulic power tongs are capable of spinning the pipe up and at times can apply the final make-up torque. There are various types of Power Tongs that can be used according to their specific use:

  • Drill Pipe Tongs: These are used to reduce the drill time and lower costs. They are designed for safe and quick make-up and break-out drill pipes and drill collars.
  • Casing Tongs: Casing power tongs are used to make or break casing tubular placed in the drill hole in order to maintain the opening of the well. Once the casing is installed, the tubing is inserted inside the casing from the opening well at the top toward the formation at the bottom. The hydrocarbons that are extracted run up this tubing to the surface. The benefit of these automated casing running and tubular handling systems was leveraged by many other innovations.
  • Tubing Tongs: Tubing Tongs provide reliable performance even at a higher torque essential to break premium connections. These are coupled with two-speed great train that assures reliability and minimal maintenance along with quick operator turn-out.
