KHT9625 套管动力钳

The KHT (KT) hydraulic power tongs are open-type power tongs applicable for making up and breaking out oil casing pipes during oil field workover operations.They featurehighoperating eiciency, significantly reducethelabor intensity of workers, improve the quality of pipe string thread connections, and reduce pipe string accidents caused by improper workover operations.
The front two-jaw-plates of the master tong are in the swing structure and the back jaw plate is the roller-climbing structure. The assembly and disassembly is very convenient. The optimum tangent-diameter ratio design ensures reliable clamping and easy slope retreating.The back tong is the three-jaw-plate structure pushed by hydraulic cylinder. The structure is simple and the clamping is reliable.
Four-gear rotation is adopted for large speed regulation range. And the rated torque is large.
It has the braking mode with braking staple.The braking torque is large.The operation is simple.And it is convenient for repair and replacement.
With the open large gear suporting structure, hardness and rigidity of open large gear is enhanced considerably:
The shellis made of stel plate with high hardness.The overall hardness isgood. Various jaw plates are made with fine casting and forging process. It has beautiful apearance and high hardness.
Hydraulic torque indicator is provided. And installation interface of turning torque instrument is provided for computerized management.
The KHT9625 casing power tong is suitable for threading the upper and lower casing strings in oilfield operations. It is a heavy-duty casing tong suitable for a maximum casing diameter of 95/8 ". Both the main and back tongs use a three jaw clamping mechanism to ensure minimal damage to the casing string. Its high operating efficiency greatly reduces the labor intensity of workers and can improve the quality of casing string thread connections, reducing casing string accidents caused by improper casing operations.
  
Characteristics：
Opening type, convenient and prompt to enter and slide off the working position, with an integral tong head of great strength and rigidity.
Both the main and back tongs adopt a three-jaw chuck mechanism, ensuring minimal damage to the tubing. The first two jaws of the main are hinged, and the rear jaw is a roller ramp, making installation and removal extremely convenient. The optimal cutting ratio design ensures reliable clamping and easy un; the back clamp is a three-jaw structure pushed by a hydraulic cylinder, with a simple structure and reliable clamping.
Four-gear rotation is adopted for large speed regulation range. And the rated torque is large;
Brake belt assembly, easy to operate and convenient to maintain and replace.
Open gear supporting structure, improving the strength and rigidity.
Wholly hydraulic mode and mechanical gear shift.
High strength steel plate used on the shell，increasing the strength.
Hydraulic torque indicator is provided. And installation interface of turning torque instrument is provided for computerized management.
