Description
Hydraulic Make-up/Break-out Unit | Hydraulic Bucking Unit for Oilfield Thread Joints
SGPE Hydraulic Make-up/Break-out Unit, also called a Hydraulic Bucking Unit, is designed for oilfield threaded connection make-up and break-out. It helps service crews tighten, loosen, assemble and repair tubing, sucker rods, downhole pumps, downhole tools, casing-related tools, couplings and other threaded petroleum components with controlled hydraulic torque.
Thread quality plays an important role in drilling support, workover service, well servicing and oilfield repair. A loose connection may lead to leakage, tool failure or downtime. Excessive torque may damage threads and shorten tool service life. Used tools may also return from the field with tight joints, oil, mud, rust or scale, which makes manual disassembly slow and unsafe.
This hydraulic make-up and break-out unit gives operators strong gripping force, smooth rotation and more consistent torque control. The machine clamps the workpiece, holds it steady and applies hydraulic torque for tightening or loosening threaded joints. As a result, service teams can reduce manual labor, protect thread surfaces and improve daily workshop productivity.
The unit is suitable for oilfield repair shops, tubing maintenance workshops, downhole pump service centers, sucker rod service facilities, drilling tool yards, workover support bases and oilfield tubular service facilities. SGPE offers YNJ160/15, YNJ200/15, YNJ205/16 and YNJ90/2 models to match different tool sizes, torque requirements, hydraulic flow rates and workshop layouts.
For customers who need higher make-up accuracy, SGPE can provide an optional automatic torque control system according to project requirements.
Product Overview
A Hydraulic Make-up/Break-out Unit is a hydraulic machine for tightening and loosening threaded joints on oilfield tubulars and petroleum tools. Buyers may also search for this equipment as a hydraulic bucking unit, hydraulic breakout machine, hydraulic make-up machine, tubing make-up machine, oilfield torque machine or oilfield thread joint machine.
The unit normally includes a head tong, a backup tong, a hydraulic drive system and control components. The head tong applies rotation torque, while the backup tong holds the workpiece and prevents unwanted movement. The hydraulic system drives clamping, releasing, rotation and backup tong movement.
Compared with manual thread handling, this machine gives operators better control during high-torque jobs. It also helps reduce direct manual force and improves safety during repeated oilfield repair work. For service shops that handle tubing, sucker rods, downhole pumps and threaded tools every day, this equipment can improve both work efficiency and connection quality.
SGPE Hydraulic Make-up/Break-out Unit supports assembly, disassembly, inspection preparation and repair work for tubing strings, rod tools, pump components, downhole tools, casing accessories and other threaded oilfield parts.

Tubing Thread Make-up and Break-out
Tubing connections must hold reliably during oil and gas production, workover and well servicing. SGPE Hydraulic Make-up/Break-out Unit handles tubing thread make-up and break-out within its rated size range. Service shops can use it for tubing repair, tubing preparation and tubular maintenance.
Sucker Rod Service
Sucker rods work in artificial lift systems, and their threaded connections affect pumping performance, service life and well uptime. SGPE Hydraulic Make-up/Break-out Unit supports sucker rod service when the selected model matches the rod size and torque requirement.
Downhole Pump and Downhole Tool Repair
Downhole pumps and tools often return from wells with tight joints, oil, scale, rust or worn thread areas. SGPE hydraulic bucking unit gives repair crews the gripping force and torque control needed to break out components, inspect internal parts, replace worn parts and make up repaired tools again.
Casing-Related Thread Joint Handling
Some SGPE models handle larger threaded oilfield components within the stated diameter range. Operators can use the unit for casing-related tools, couplings and other oilfield thread joint parts. This flexibility helps service bases process different tubular products with one machine.
Key Features
1. Simultaneous Clamping and Releasing
The head tong and backup tong can clamp or release at the same time. This design improves working rhythm during oilfield tool assembly and disassembly. Operators can complete clamping and releasing more smoothly without repeated separate control steps.
Simultaneous clamping also keeps the workpiece stable. The head tong and backup tong grip the threaded joint together, reduce unwanted movement and help protect thread surfaces during make-up and break-out.
2. Four Planetary Claws for Stable Gripping
The head tong and backup tong use four planetary claws. This structure distributes gripping force around the workpiece and helps the unit hold tubing, sucker rods, casing-related tools and downhole tools securely during rotation.
Stable gripping is important in oilfield maintenance because used tools may have oily surfaces, worn thread areas or tight joints after long service. The four-claw structure helps reduce slipping and gives operators better control during high-torque break-out work.
3. Bidirectional Clamping Mechanism
The bidirectional clamping mechanism supports both make-up and break-out work. Operators can switch between tightening and loosening without complicated part changes.
This feature suits repair shops that handle different jobs during one shift. For example, a crew may break out used downhole tools, inspect parts and make up repaired tools again with the same machine.
4. Wide Working Range Without Frequent Part Changes
The unit covers its rated application range without frequent part replacement. This saves preparation time, improves equipment utilization and reduces the risk of using the wrong accessories.
Oilfield repair shops often process different tubing sizes, tool bodies and threaded components. A wider operating range helps one machine support more jobs and reduces downtime between workpieces.
5. Optional Automatic Torque Control System
SGPE can provide an automatic torque control system according to customer requirements. This option helps operators control make-up torque more accurately and improve assembly consistency.
Torque control affects connection quality. Low torque may cause loose joints. Excessive torque may damage threads or shorten service life. With automatic torque control, service teams can follow target torque values and reduce human error during tool assembly.
6. Hydraulic Walking Backup Tong
The backup tong includes a hydraulic walking mechanism and can move with the tube during operation. This feature helps operators handle long workpieces and repeated thread joints more conveniently.
In tubing service, sucker rod maintenance and downhole tool repair, crews often work with long or heavy components. Hydraulic walking reduces manual adjustment and supports smoother workflow.
7. Four-Speed Operation
The unit offers four speeds. Operators can choose a suitable speed according to thread size, torque requirement and work stage. Higher speed supports initial rotation, while lower speed supports final torque control.
This flexibility improves both efficiency and precision, especially when one workshop handles different thread sizes and joint conditions.
8. Stable Hydraulic Drive
The hydraulic drive system provides strong output and smooth movement. It suits oilfield service environments where tools may carry oil, mud, rust and heavy field wear.
Hydraulic operation reduces manual effort and helps crews complete make-up and break-out work with stable performance. For high-frequency maintenance work, this improves safety, productivity and operation consistency.
Benefits for Oilfield Service Companies
SGPE Hydraulic Make-up/Break-out Unit helps oilfield service companies, workover contractors, well servicing companies and petroleum equipment repair shops improve daily threaded connection work.
