What is Tong torque?
Tong Torque System: 1 quart of Crown Oilfield Instrumentation all-weather instrument fluid. Indicates torque in foot pounds applied to each joint when using power tongs to run oilfield tubular. Models available for all makes and models of power tongs.
What is a tong system?
Power Tong Systems. Matherne Instrumentation’s power tong system is designed to assure uniform and proper make-up of the string by indicating accurate torque applied to each joint when running pipe or casing. The system can help reduce drill collar and tool joint failure resulting from improper make-up.
How is rig Tong length measured?
Handle lengths are measured from the center of the tong to the end of the handle. If this measurement is in inches, it will need to be converted to feet in order to find max torque.
What is a tong line?
Tong Line Pull System with tension load cell is important in reducing drill collar and toll joint failure. Tong Line Pull Systems indicate the applied torque to each joint when the tongs are used to make up pipe, tubing, casing joints or drill collars.
What is rig Tong?
Rig tongs are large self-locking wrenches that are used to spin pipe and in some cases apply the final makeup torque. There are a variety of rig tongs available dependent on what application they’ll be used for. Some examples are: casing tongs, power tongs, rotary tongs and manual tongs.
How much do drilling rig tongs weigh?
Its handle and handguard protect hammer blows from falling onto the grip. Straight tong die drivers are lightweight—under eight pounds—and measure in at around 1”.
What is make up torque?
The rotational force used to make up a connection in the string. Drill pipe failure may occur when the make-up torque of a connection is exceeded.
What are Tong dies made of?
Many types of rig tongs can also be fitted with dies, which provide a specialized surface on the interior of the eye. They are typically made from extremely durable materials, like alloy steel, designed to resist corrosion and damage.
What are pipe tongs used for?
Power tongs are essentially large pneumatically or hydraulically operated rig tongs used for turning when making up or breaking out drill pipe, casing, tubing, or other pipe.
What PPE is required to change Tong and slip dies?
Always wear goggles when changing tong dies.
What is the most common injury on a rig site?
Injuries in this industry vary dramatically, from injured hips caused by falls to severe burns from explosions. However, the most common injury was amputation, primarily caused by fingers getting caught in machinery. Fractures were the second most common injury. Legs were the body part most commonly fractured.
What is the most common injury on a rig site?*?
Oil and gas accident statistics from the U.S. Bureau of Labor Statistics show that the most common type of oilfield accident is workers being struck by falling objects, often from collapsing decking or work rigs.
How do I find max torque for a Tong?
Handle lengths are measured from the center of the tong to the end of the handle. If this measurement is in inches, it will need to be converted to feet in order to find max torque. Once you have the max torque needed and the handle length in feet, you can complete the formula. The example below shows the formula in action.
What is a Tong torque gauge used for?
A tong torque gauge is calibrated to a specific tong handle length and thus reads in foot/pounds instead of force/pounds. The advantage to the gauge readings being foot/pounds is that the driller does not have to convert the gauge measurement in order to know the foot pounds being imposed on the drill string.
How do you use a hydraulic Tong gauge?
This system is used in applications where there are two or more sets of tongs being used with differing handle lengths. A 6” fluid-filled gauge reads the pounds of line pull from the tong handle. As the joints are made-up, the line pull is converted to hydraulic pressure within the cylinder, and sent to the gauge through the rubber hose.
Is a Tong line pull gauge Universal?
A tong line pull gauge is universal. As long as the tong is a manual tong, a tong line pull gauge will fit on any hydraulic tong system. No matter what the tong’s handle length, a tong line pull gauge will measure force/pounds. The advantage to these gauges is that because they are universal, they can be used on any manual tong system.
