XQ140 Hydraulic power tong is used to make up and break out for 23/8″-31/2″drill pipe、31/2″-41/2″tubing and 41/2″-51/2″casing during oil field workover operation,it is a kind of opening type power tong. And three-jaw-plate clamping device is adopted in the master tong and back tongs.The device may ensure minimum string damage. It has high operation efficiency and may reduce working intensity of…
Characteristics：
1．Opening type,convenient and prompt to enter and slide off the working position,with an integral tong head of great strength and rigidity;
2．Three-jaw-plate clamping device is adopted in the master tong and back tongs, which can ensure minimum string damage. Front jaw of master tong is swing type,rear jaw is roller climbing type, convenient to assemble and disassemble,the best design of diameter ratio,ensure the reliable clamping, Three-jaw-plate structure is adopted in the master tong and back tongs,this structure is hydraulic cylinder pushing and clamping style,it can clamp the body of the tubular,and also can clamp the coupling,with simple structure and reliable clamping.
3．Only needs to change the Hardware alloy coating die(low stress point-like mark left on the tubular column,no straight strip tooth mark,No tooth mark die for short.it is recommended to use on 3Cr、9Cr、13Cr、22Cr、25Cr tubing and casing or fine tooth die(tiny straight strip tooth mark left on the tubular column, Micro tooth mark die for short.)
- Four-gear rotation is adopted for large speed regulation range,and the rated torque is large;
- Safety door interlock device is adopted, when the safety door is open,the tong head will not revolve,it is safe and reliable.
6．The overall frame structure is adopted in the master tong and back tong,floating connection of the backup tong,distance between the master tong and backup tong can be adjusted,damage can be reduced to the tubular column in make up and break out operation.
7．To be used along with Double pump hydraulic power station,it can realize a rotate speed of 20 ～ 25rpm when make up in the beginning,then fastening at a speed of 1～6rpm after reaching the shouldering torque.
8．To be used along with Torque and rotational speed test system and Double pump hydraulic power station can precisely control the make up torque and rotation speed,it can display.
