CHINA SCOTON OILFIELD EQUIPMENT CO., LTD.

Hydraulic power tong is a workover tool that utilizes the power of the drilling rig to remove the workover tool. The advantages are obvious and easy to use.

Drilling process in the operation of the largest workers, the most heavy workload is on, unloading pipe fittings and drill thread, in the past has been with a pipe clamp or chain clamp, not only labor-intensive, and dangerous. Hydraulic power clamp is the use of oil rig power operation of the mechanical, unloading deduction tool, can greatly reduce the labor intensity of the workers to avoid or reduce the occurrence of injury accidents. At the same time, hydraulic power tongs to strengthen the pipe, drill wire twist torque, reduce the pipe, drilling tool trip accident occurred. The working principle of the hydraulic power clamp is to pass the power of the drilling rig to the hydraulic power clamp hydraulic motor by the stroke reducer, and then by two or one deceleration, the jaw opening gear rotation, resulting in two high and low speed, Pipe tool (drill) rotation. When the opening gear rotates, the plate frame does not rotate under the braking action of the brake hammer, so that there is a relative movement between the opening gear and the palmar plate. In this way, the two rollers of the palmar plate will climb on the slope plate and force the clamp on the hips board to move toward the center of the pipe (drill) until it is clenched with the tool and then with the opening gear Together drive the pipe (drill) to rotate.

Ⅰ SKT SERIES DUAL-PURPOSE POWER TONGS

SKT series dual-purpose power tongs is applicable to tripping operation and running-in casing operation in the drilling activities in petroleum and mining. It is a new power tongs dependently developed by ourselves according to the requirements from oilfield customers. The power tong integrates the function of drill pipe power tong and casing power tong. It can meet the requirements under the operation of frequent tripping or connecting single pipe. In addition, it can be used to run in the casing with small diameter. During the conversion between the two operations, it is not necessary to replace the equipment. It can increase the wellhead operation efficiency and reduce the labor intensity.

Ⅱ Low Stress Power Tong

Low stress hydraulic power tong is applied for unloading 2 3/8"-4 1/2 tubing and 4 1/2"-5 1/2"casing pipe in marine oil filed and well service operation. It's an open-throat designed power tong. It's an improvement basing on absorbing the advantaged product skill of the world, with changing the special clamp head, which can improve the wearness of tube and no indentation, widely used in the marine oil filed, the high sulfur content field for unloading 9 Cr, 13 Cr, 22 Cr, 25 Cr and other special pipe.


  • Product features describe as:1. Master tong with double brake structure, greatly increased the braking force ,which can ensure reliable clamping, preventing from slippage .
  • The machine is a combination of master and backup tong, by operating the multiple valve lever, which can realize the tongs respectively clamping or loosen .
  • Equipped with extend leading bar and gantry back-up bar, can realize the tongs clamping concurrently,facilitate for the sensor installation, to ensure no twisting while processing .Ensure the torque device performs accurately.
  • Back-up tong with double oil cylinder lever clamping structure, may realize tong head clamping pipe surrounded.
  • Equipped with self locking door device is to protect the safety of the operators.
  • The torque automatic control system is optional , the effect would be better if installed .
