API 7K Hydraulic Make-Up And Break-Out Machine Hydraulic Bucking Unit For Casing And Tubing Buck On Machine Buck Off Machine

This hydraulic Bucking Unit adoptes the working desgin of industry’s push and pull assembly

It is highly automated supports a wide range of tools and tube dimeter(60-260mm) in thread guiding and tools alignment, in order to ensure maximum protection of work piece surface during operation, the unit uese special rorary screw clamps(quicky-rotary screw tongs) with no teetch marks, its ease of operation and maintenance help users save operation cost and time.

Hydraulic bucking unit is an important equipment for makeup / breakout, repairing all kinds of tools such as drill tools, pipe stems and downhole tools for petroleum and geological prospecting industries. It is designed and manufactured on the basis of the advanced technology from same equipment abroad and the actual situation of the petroleum industry
in China.

In view of design construction, we obtained pieces of state patented protection tight, state certificate for new product, high-tech. certificate of provincial grade, also we got may scientific technology award for state and provincial grade.

It owns some advantages such as high automatic function, big makeup / breakout torque, wide pipe diameter range, no sliding when makeup / breakout. Meanwhile, it also has good function for quick makeup / breakout, axial pulling.

The hydraulic bucking unit has got good reputation from customers domestic and abroad and well exported to many countries and regions.

Hydraulic Bucking Unit

  • 1.BHJG570 bucking machine is driven and controlled by both hydraulic and pneumatic system. The system is simple, also has convenient and flexible manipulation.
  • 2.The system is controlled by pneumatic except for power tong hydraulic motors so that can greatly reduce the oil leakage.
  • 3.The power tong uses closed form, which is driven by hydraulic motor with roller climbing clamping. The clamp head include 4 jaw plates with 90º proportional distributing, every jaw plate has 4-6 teeth. A total of 16-24 teeth contact the coupling surface with reliable clamping. Teeth marks accord with API standard. The clamp head is reset by means of automatic positioning machinery, quickly and reliably.
  • 4.The backup tong also uses closed form, which is driven by the pneumatic cylinder. The jaw clamping rollers climbing principle is similar to the driving clamp.
  • 5.The power tong and the backup tong can automatically regulate to meet the casing and coupling which have a little bending.
  • 6.The replacement of dies is convenient.
  • 7.The backup tong is equipped with tension sensor which is used to measure torque (the unit is k.Nm). Control system will contrast the torque value and screw circles to the setting value, so that the bucking machine operates automatically.
