Description
Drill Pipe Power Tong for Drilling Rig Make-Up, Break-Out and Tripping Operations
SGPE Drill Pipe Power Tong provides powered spinning, make-up and break-out for drill pipe tool joints during drilling, tripping, workover and drill string handling.
The Hydraulic Drill Pipe Power Tong grips the tool joint, rotates the connection in either direction and applies controlled torque for final make-up or break-out. By combining fast spinning with high-torque operation, it reduces dependence on manual rig tongs, catheads and spinning ropes during routine rig-floor work.
SGPE manufactures ZQ Series Hydraulic Drill Pipe Power Tongs for land drilling rigs, offshore rigs and workover units. Typical models include ZQ127/25, ZQ162/50, ZQ203/100 and ZQ203/125, with maximum torque from approximately 25 to 125 kN·m / 18,440 to 92,200 ft-lb.
Customers can order the master tong alone or build a complete drill pipe make-up and break-out system with a hydraulic backup tong, HPU, suspension or lifting system, hydraulic hoses, tong dies, torque monitoring and recommended spare parts.
Correct selection starts with the connection itself. SGPE reviews the tool joint OD, usable gripping length, connection type, make-up torque, expected break-out torque, hydraulic pressure, hydraulic flow and rig-floor layout before recommending a tong.

ZQ Series Hydraulic Drill Pipe Power Tong Models
The ZQ Series Drill Pipe Power Tong covers several gripping ranges and torque levels. This allows drilling contractors, rig builders and service companies to select a model around the actual tool joint and drilling program rather than nominal pipe OD alone.
| Model | Typical Gripping Range | Max. Torque | High / Low Speed | Hydraulic Pressure | Typical Flow |
|---|---|---|---|---|---|
| ZQ127/25 | 65–127 mm | 25 kN·m / 18,440 ft-lb | 65 / 10.5 rpm | Approx. 12 MPa / 1,740 psi | Approx. 120–180 L/min |

The model number is only a starting point. Tool joint diameter, connection torque, available hydraulic power and installation space all affect the final selection.
ZQ203/125 Hydraulic Drill Pipe Power Tong
The ZQ203/125 Drill Pipe Power Tong suits heavy-duty drilling programs that need greater torque for make-up or difficult break-out.
A representative ZQ203-125Ⅱ configuration provides the following reference data:
| Parameter | ZQ203-125Ⅱ Reference |
|---|---|
| Gripping Diameter | 127–203.2 mm |
| Maximum Low-Gear Torque | 125 kN·m / 92,200 ft-lb |
| High-Gear Torque at 20.7 MPa | Approx. 8.5 kN·m / 6,270 ft-lb |
| Rated Hydraulic Flow | 114 L/min / 30.12 gpm |

Different ZQ203/125 versions may use different lifting, suspension or positioning arrangements. SGPE confirms final dimensions and operating weight for each project.
Hydraulic Requirements, Speed and Torque Performance
A hydraulic power tong for drill pipe needs sufficient oil flow for useful spinning speed and enough working pressure for the required torque.
The rig hydraulic system should also provide a suitable return line, acceptable back pressure, clean hydraulic oil and adequate cooling for the expected duty cycle.
Hydraulic Flow vs. Tong Speed
The following values apply to a representative ZQ203-125Ⅱ configuration.
| Hydraulic Flow | High-Gear Speed | Low-Gear Speed |
|---|---|---|
| 114 L/min / 30.12 gpm | 40 rpm | 2.7 rpm |
| 100 L/min / 26.42 gpm | 35.1 rpm | 2.4 rpm |
| 90 L/min / 23.78 gpm | 31.6 rpm | 2.1 rpm |
| 80 L/min / 21.13 gpm | 28 rpm | 1.9 rpm |
| 70 L/min / 18.49 gpm | 24.5 rpm | 1.7 rpm |
| 60 L/min / 15.85 gpm | 21 rpm | 1.4 rpm |
| 50 L/min / 13.21 gpm | 17 rpm | 1.0 rpm |
Lower hydraulic flow can still operate the tong, but spinning speed will decrease.
Hydraulic Pressure vs. Output Torque
| Hydraulic Pressure | High-Gear Torque | Low-Gear Torque |
|---|---|---|
| 20.7 MPa / 3,000 psi | Approx. 8.5 kN·m | Approx. 125 kN·m |
| 20.0 MPa / 2,900 psi | Approx. 8.2 kN·m | Approx. 120 kN·m |
| 17.0 MPa / 2,465 psi | Approx. 6.95 kN·m | Approx. 102.3 kN·m |
| 15.0 MPa / 2,176 psi | Approx. 6.1 kN·m | Approx. 90.3 kN·m |
| 13.0 MPa / 1,885 psi | Approx. 5.29 kN·m | Approx. 78.2 kN·m |
| 11.0 MPa / 1,595 psi | Approx. 4.46 kN·m | Approx. 66.0 kN·m |
| 9.0 MPa / 1,305 psi | Approx. 3.63 kN·m | Approx. 53.8 kN·m |
Operators should follow the approved connection make-up torque rather than simply running the tong at maximum hydraulic pressure.
How an Open-Throat Drill Pipe Power Tong Works
Many ZQ models use an open-throat drill pipe power tong design.
The tong approaches the drill pipe from the side. After completing the connection cycle, the crew can move it away without passing the full drill string through a closed head.
During make-up, high gear spins the tool joint quickly. As the connection approaches the shoulder, the operator switches to low gear and applies higher torque.
During break-out, the tong first applies enough reverse torque to loosen the connection. Once the joint releases, the same tool continues spinning it apart.
This gives one hydraulic tong both fast spinning and controlled torqueing functions.
Selected configurations also include hydraulic shifting or lifting systems for easier movement between working and parking positions.
Select the Power Tong by Tool Joint OD, Not Pipe OD Alone
The tong normally grips the drill pipe tool joint, not the pipe body.
For this reason, two drill pipes with the same nominal OD can require different dies, gripping ranges or torque capacities.
| Selection Data | Why It Matters |
|---|---|
| Drill Pipe OD | Identifies nominal pipe size |
| Drill Pipe Grade | Adds drill string information |
| Tool Joint OD | Determines gripping range |
| Tool Joint Gripping Length | Confirms usable jaw contact area |
| Connection Type | Identifies connection geometry |
| Recommended Make-Up Torque | Determines required tong output |
| Expected Break-Out Torque | Determines torque reserve |
| Number of Tool Joint Sizes | Determines die requirements |
| Rig Hydraulic Pressure | Determines available torque |
| Rig Hydraulic Flow | Determines operating speed |
Providing these values with the RFQ shortens technical clarification and improves model selection.
Drill Pipe Power Tong for NC, IF, FH and REG Connections
SGPE can review tongs for NC, IF, FH, REG and proprietary rotary shouldered connections.
Common NC connections include NC26, NC31, NC38, NC40, NC46 and NC50. However, the connection designation alone does not confirm compatibility because actual tool joint OD and recommended make-up torque can vary.
IF connections remain common on many existing drill strings, while FH connections appear on selected drill pipe and older drilling programs. REG connections are also used on drilling tools and selected drill string components.
For premium or manufacturer-specific rotary shouldered connections, provide the connection datasheet and recommended torque. SGPE can then verify the gripping diameter, die arrangement and required tong capacity.
5-Inch Drill Pipe and NC50 Power Tong Selection
A 5-Inch Drill Pipe Power Tong must match the actual tool joint rather than the 5-inch pipe body alone.
Depending on tool joint OD and torque requirement, a ZQ162 or ZQ203-series model may suit the application.
For 5-inch drill pipe with NC50, provide the tool joint OD, usable gripping length and recommended make-up torque before ordering.
This allows SGPE to confirm the tong model, jaw arrangement, die set and torque capacity.
Drill Pipe Power Tong with Backup Tong
A Drill Pipe Power Tong with Backup Tong creates a coordinated hydraulic make-up and break-out system.
The master tong rotates the upper tool joint while the backup tong grips the lower connection and absorbs reaction torque.
This arrangement improves stability during repeated connection cycles and works particularly well for frequent tripping, heavy drill strings and higher-torque operations.
The backup tong also needs the correct gripping range. SGPE therefore checks both upper and lower gripping points before confirming the package.
Drill Pipe Power Tong with Hydraulic Power Unit
A Drill Pipe Power Tong with HPU provides an independent hydraulic source when the existing rig system cannot supply enough pressure, flow or cooling capacity.
| HPU Component | Function |
|---|---|
| Hydraulic Pump | Generates pressure and flow |
| Electric Motor / Diesel Engine | Drives the pump |
| Oil Reservoir | Stores hydraulic oil |
| Suction / Return Filters | Control contamination |
| Relief Valve | Protects the hydraulic circuit |
| Pressure Gauge | Displays operating pressure |
| Oil Cooler | Controls oil temperature |
| Directional Valves | Control hydraulic functions |
| Pressure / Return Hoses | Connect the HPU and tong |
For an electric HPU, provide the required voltage and frequency. For a diesel-driven unit, confirm the installation environment and ambient temperature.
An independent hydraulic power unit is especially useful for rig refurbishment, workover rig upgrades and replacement ZQ power tong projects where the existing rig hydraulics do not match the new tong.
Drill Pipe Power Tong Torque Monitoring
Correct make-up torque helps protect tool joint threads and shoulders.
SGPE can configure several levels of Drill Pipe Power Tong Torque Monitoring, ranging from basic pressure indication to digital recording.
| Option | Typical Function |
|---|---|
| Hydraulic Pressure Indication | Basic torque reference |
| Analog Torque Gauge | Routine rig-floor monitoring |
| Digital Torque Display | Real-time numerical reading |
| Torque Sensor | Improved torque measurement |
| Preset Torque Alarm | Alerts operator near target torque |
| Digital Torque Recorder | Stores connection records |
| Torque Monitoring Panel | Integrates display and control |
| Data Interface | Supports project-specific data output |
Projects that need traceable make-up data can specify a Digital Power Tong Torque Monitoring and Recording System.
Customers should define the required torque range, accuracy, calibration and data-output requirements during the RFQ stage.
Power Tong Dies, Jaws and Replacement Inserts
The gripping system directly affects how reliably the tong transfers torque to the tool joint.
SGPE supplies Drill Pipe Power Tong Dies, Jaw Inserts and Replacement Gripping Parts for different tool joint diameters.
Depending on the model, the gripping system can include replaceable dies, complete jaws, retainers, pins, rollers, bushings and springs.
When one drilling rig handles several tool joint sizes, customers can order additional die sets with the main equipment.
For replacement dies, jaws or inserts, provide the tong manufacturer, model, tool joint OD, part number if available, key dimensions and clear photographs.
Drill Pipe Power Tong Applications
| Application | Typical Operating Need | Selection Focus |
|---|---|---|
| Land Drilling Rig | Routine drilling and tripping | Gripping range, torque and hydraulic flow |
| Offshore Platform Rig | Reliable connection work | Layout, suspension and spare parts |
| Jack-Up Rig | Frequent drilling and round trips | Torque and hydraulic interface |
| Semi-Submersible Rig | Offshore drill string handling | Installation and project requirements |
| Drillship | Frequent connection cycles | Rig integration and maintenance planning |
| Workover Rig | Drill pipe / approved work-string handling | Compact layout and gripping range |
| Deep Well Drilling | Higher break-out demand | Torque reserve |
| Directional Drilling | Long drilling cycles | Gripping reliability and torque control |
| Horizontal Drilling | Extended drill string operation | Torque capacity and service support |
| Tripping Operations | Repeated make-up and break-out | Spinning speed and backup arrangement |
| Rig Refurbishment | Replacement of obsolete equipment | Hydraulic and dimensional compatibility |
Land Drilling Rig Power Tong
A drill pipe power tong for land rigs supports drilling, tripping and drill string assembly on exploration and development wells.
When the existing rig hydraulic system provides enough pressure and flow, the tong can use that supply. Otherwise, SGPE can provide an independent HPU.
Offshore Drill Pipe Power Tong
The ZQ series can support platform rigs, jack-ups, semi-submersible rigs and drillships when the selected configuration matches the installation environment.
Offshore projects usually require closer review of installation space, suspension points, hydraulic interfaces, maintenance access and critical spare parts.
Workover Rig Power Tong
A suitable hydraulic power tong for workover rigs can handle approved drill pipe or work-string connections during well repair and intervention.
Typical operations include fishing, milling, cleanout, recompletion and sidetrack preparation. Tool joint OD, torque requirement, available hydraulics and rig-floor space determine the final configuration.
Power Tong for Tripping, Deep and Directional Drilling
Frequent tripping increases the number of make-up and break-out cycles, so spinning speed, gripping reliability and backup-tong arrangement become more important.
Deep, directional and horizontal drilling can also increase break-out demand after extended drilling intervals. For these projects, SGPE can review higher-torque ZQ203/100 or ZQ203/125 models.
Actual connection torque remains more important than well depth alone.
Replacement ZQ Power Tong and Rig Retrofit
SGPE supports Replacement Drill Pipe Power Tong, ZQ Power Tong Retrofit and legacy tong replacement projects for existing drilling and workover rigs.
Common requirements include ZQ127/25, ZQ162/50, ZQ203/100 and ZQ203/125 replacement units.
For accurate matching, provide the existing manufacturer, model, nameplate, gripping range, torque rating, hydraulic pressure, hydraulic flow, dimensions, operating weight, suspension arrangement and hydraulic interfaces.
A rig-floor GA drawing and clear equipment photographs can also help determine whether the replacement tong can fit the existing installation with minimal modification.

Customers requiring TPI, witness or hold points, FAT, ITP or an MDR/document dossier should identify these requirements during the RFQ stage.
Drill Pipe Power Tong vs. Manual Rig Tong vs. Iron Roughneck
| Item | Drill Pipe Power Tong | Manual Rig Tong | Iron Roughneck |
|---|---|---|---|
| Main Function | Powered make-up / break-out | Manual torque application | Integrated connection handling |
| Power | Hydraulic | Mechanical / tong line | Hydraulic / electro-hydraulic |
| Spinning | Integrated on suitable configurations | Separate | Usually integrated |
| Torque Monitoring | Optional | Separate | Usually integrated |
| Installation Complexity | Medium | Low | High |
| Footprint | Medium | Small | Larger |
| Retrofit Potential | High | High | Requires detailed rig review |
| Automation Level | Low to medium | Low | Medium to high |
| Typical Application | Drilling and workover | Backup/manual work | Mechanized rig floors |
A hydraulic power tong offers a practical rig retrofit when powered drill pipe connection handling is required without installing a complete iron roughneck system.
Drill Pipe Power Tong vs. Tubing and Casing Power Tongs
A Drill Pipe Power Tong handles drill pipe tool joints and rotary shouldered connections during drilling and tripping.
A Tubing Power Tong handles tubing connections during completion and workover, while a Casing Power Tong handles casing joints and couplings during casing running.
Although their nominal size ranges can overlap, the gripping arrangements, jaw designs and torque requirements differ. Always select the tong according to the actual tubular and connection.
Drill Pipe Power Tong Manufacturer and Supplier
SGPE manufactures hydraulic drill pipe tongs in China for drilling contractors, oilfield service companies, EPC contractors, rig builders, repair facilities and equipment distributors.
Customers can purchase the master tong alone or source a complete package with a backup tong, HPU, suspension system, hydraulic hoses, tong dies, torque monitoring system and spare parts.
SGPE supports new drilling packages, ZQ power tong replacement, rig retrofit, hydraulic upgrades and maintenance requirements.
Technical datasheets, drawings, manuals, FAT records and other project documentation can form part of the agreed supply scope.
What Affects Drill Pipe Power Tong Price?
Drill Pipe Power Tong price depends on the model, gripping range, torque rating and package scope.
A master tong alone costs less than a complete system with a backup tong, independent HPU, lifting arrangement, digital torque monitoring and spare parts.
The quotation can also change according to the number of die sets, hydraulic configuration, HPU type, inspection requirements, documentation, packing and delivery terms.
For an accurate Drill Pipe Power Tong quotation, provide the actual tool joint and rig hydraulic data instead of requesting price by nominal pipe size alone.
How to Select the Right Drill Pipe Power Tong
Start with the drill pipe connection.
Confirm the nominal drill pipe size, grade, actual tool joint OD and usable gripping length. Then provide the connection type, recommended make-up torque and expected break-out torque.
Next, confirm rig hydraulic pressure, maximum flow and return-line condition. These values determine whether the existing supply can provide enough torque and spinning speed.
Finally, review the rig-floor arrangement and decide whether the project needs a backup tong, independent HPU, additional dies, digital torque monitoring, suspension equipment or spare parts.
This approach gives a more reliable result than selecting a tong from nominal pipe size or model number alone.

Frequently Asked Questions About Drill Pipe Power Tongs
1. What is a Drill Pipe Power Tong and how does it work?
A Drill Pipe Power Tong is a hydraulic rig-floor tool used to spin, make up and break out drill pipe tool joints during drilling, tripping and workover operations. During make-up, the tong first spins the connection at higher speed and then switches to lower speed with higher torque for final tightening.
During break-out, it applies reverse torque to loosen the tool joint and then continues spinning once the connection releases. This combination helps reduce reliance on manual rig tongs, catheads and spinning ropes.
2. What drill pipe sizes can a Hydraulic Drill Pipe Power Tong handle?
The correct Hydraulic Drill Pipe Power Tong size range depends mainly on the actual tool joint OD rather than the nominal drill pipe body diameter.
Typical ZQ-series models cover gripping diameters of approximately 65–203 mm, with different models suited to different tool joints and torque requirements. For accurate selection, provide the drill pipe size, tool joint OD, usable gripping length and connection type. This is especially important when the same nominal drill pipe size uses different tool joint dimensions.
3. What torque range is available for ZQ Drill Pipe Power Tongs?
Typical ZQ Drill Pipe Power Tong torque ratings range from approximately 25 kN·m to 125 kN·m. The ZQ127/25 provides about 25 kN·m, the ZQ162/50 about 50 kN·m, the ZQ203/100 about 100 kN·m and the ZQ203/125 up to approximately 125 kN·m.
The correct model should cover the recommended make-up torque and still provide suitable reserve for break-out. Higher torque is not always better because gripping range, hydraulic supply and rig layout also affect model selection.
4. What is the difference between ZQ203/100 and ZQ203/125 Drill Pipe Power Tongs?
The main difference between the ZQ203/100 and ZQ203/125 Power Tong is maximum torque capacity. The ZQ203/100 reaches approximately 100 kN·m / 73,750 ft-lb, while the ZQ203/125 can reach approximately 125 kN·m / 92,200 ft-lb.
The ZQ203/125 is therefore better suited to applications that require greater make-up or break-out torque, but the final choice also depends on tool joint OD, hydraulic pressure, flow, suspension arrangement and available rig-floor space.
5. Does a Drill Pipe Power Tong need a backup tong?
A backup tong is not required for every project, but a Drill Pipe Power Tong with Backup Tong provides a more complete make-up and break-out system. The master tong rotates the upper tool joint while the backup tong grips the lower connection and absorbs reaction torque.
This arrangement improves stability during repeated connection cycles and is particularly useful during frequent tripping, heavy drill string handling and higher-torque operations on land or offshore drilling rigs.
6. Can a Drill Pipe Power Tong use the existing drilling rig hydraulic system?
Yes, the tong can use the existing rig hydraulic system if it provides sufficient pressure, oil flow, return-line capacity and cooling. Hydraulic pressure has a major effect on available torque, while flow influences spinning speed.
For example, a representative ZQ203-125Ⅱ can reach about 40 rpm high speed and 2.7 rpm low speed at 114 L/min. For retrofit or replacement projects, SGPE reviews the existing rig hydraulics before confirming whether a separate HPU is necessary.
7. Can SGPE supply a Drill Pipe Power Tong with an HPU?
Yes. SGPE can supply a Drill Pipe Power Tong with Hydraulic Power Unit when the existing rig hydraulic system cannot provide enough pressure, flow or cooling capacity.
The HPU can include the hydraulic pump, electric motor or diesel engine, reservoir, filters, oil cooler, relief valve, gauges, control valves and hydraulic hoses. Independent HPUs are commonly used for new drilling packages, workover rigs, rig refurbishment and replacement ZQ power tong projects.
8. How can Drill Pipe Power Tong make-up torque be monitored?
Make-up torque can be monitored using hydraulic pressure indication, analog torque gauges, digital displays, torque sensors, preset alarms or electronic recording systems. Projects that require better traceability can use a Digital Power Tong Torque Monitoring and Recording System to record connection data.
The required torque range, measurement accuracy, calibration and data-output format should be confirmed before ordering, especially for drilling programs with stricter connection-control requirements.
9. Can one Drill Pipe Power Tong handle NC50, IF, FH and REG connections?
Yes, one tong may handle different drill pipe connections if the actual tool joint OD falls within the approved gripping range and the tong provides sufficient torque.
SGPE can review NC, IF, FH, REG and proprietary rotary shouldered connections, including common NC sizes such as NC26, NC31, NC38, NC40, NC46 and NC50. For a 5-inch drill pipe with NC50, provide the actual tool joint OD, gripping length and recommended make-up torque so the correct tong model and die set can be confirmed.
10. Where can Drill Pipe Power Tongs be used?
Drill Pipe Power Tongs are used on land drilling rigs, offshore platforms, jack-up rigs, semi-submersible rigs, drillships and workover units. Typical applications include drilling, tripping, drill string assembly, workover, fishing, milling, cleanout and rig retrofit projects.
Higher-torque ZQ203-series models can also support deep, directional and horizontal drilling where the connection requires additional break-out capacity. Actual tool joint torque remains more important than well depth alone when selecting the tong.
11. Can SGPE supply replacement ZQ Power Tongs and spare parts?
Yes. SGPE can review replacement ZQ Power Tong and rig retrofit requirements for ZQ127/25, ZQ162/50, ZQ203/100 and ZQ203/125 models. Replacement projects can be matched according to the existing model, nameplate, gripping range, torque rating, hydraulic pressure, oil flow, dimensions and suspension arrangement.
SGPE also supplies Drill Pipe Power Tong spare parts, including dies, jaws, inserts, gears, shafts, bearings, hydraulic motors, valves, hoses, seals, gauges and suspension components.
12. What information is needed for a Drill Pipe Power Tong quotation?
For an accurate Drill Pipe Power Tong quotation, provide the drill pipe size, tool joint OD and gripping length, connection type, required make-up torque, expected break-out torque, rig type, hydraulic pressure and oil flow. Also confirm whether the project requires a backup tong, HPU, additional die sets, torque monitoring, spare parts, suspension equipment, FAT, TPI, ITP or project-specific documentation.
For replacement or retrofit projects, the existing tong model, nameplate, GA drawing or clear equipment photos can also help. SGPE will review this information and recommend the appropriate ZQ power tong configuration before preparing the technical and commercial quotation.
