Tong Line Pull and Tong Torque Gauges

Tong Torque Gauges & Tong Line Pull

Tong Torque measurement systems accurately indicate torque applied to oilfield tubulars during make up and breakout operations, thereby reducing under and over torquing which can cause tubular failure. Each tong torque system consists of a hydraulic load cell (tension or compression type), hose assembly, 6" fluid filled gauge with damper assembly and recharge kit consisting of hand pump, and 1 quart of Crown Oilfield Instrumentation all weather instrument fluid. The two main types of Tong Torque Systems are:

Tong Line Pull Gauges

Indicates make-up or break-out torque (in pounds of line pull) for tool joints, drill collars, and drill string components. This type of system is used in applications where there are more than on set of tongs being used with different handle lengths. A 6” fluid-filled gauge reads directly in pounds of line pull which works in conjunction with a load cell that is connected directly to the tong handle. As each joint is made up, line pull is converted to a hydraulic pressure signal within the cylinder and sent to the gauge via a rubber hose, the gauge displays this signal as pounds of line pull. To determine the actual torque being applied you multiply the gauge reading by the tong handle length in feet. The gauge comes complete with a target pointer that the driller sets to a corresponding torque requirement. A large variety of systems are available with up to 30,000 pounds of single line pull. English, Metric, or dual scale systems are available.

Tong Torque Gauges

Indicates torque in foot pounds applied to each joint when using power tongs to run oilfield tubulars. These systems are available for all makes and models of power tongs and come with either compression or tension type load cells that provide an accurate check of make up torque for all oilfield tubulars. Dual scale variations are also available. Rugged, simple load cell designs guarantee extra long life and ease of maintenance.

Tong Torque Systems consist of a Tension or Compression Load Cell, 6” fluid filled Gauge, 5’ hydraulic hose (additional hose lengths available), fluid hand pump and 1quart of Crown Oilfield Instrumentation all weather instrument fluid.
