Type B Manual Tong for Drill Pipe and Casing
The Type B Manual Tong remains one of the most common manual rig tongs for drilling and workover operations. Its broad gripping range and practical torque capacity make it suitable for many routine tubular connections.
Typical configurations grip drill pipe tool joints, casing couplings, drilling subs and other approved tong areas from approximately 3-1/2 to 13-3/8 inches. However, the full range requires several lug jaw options. Crews must install the correct jaw for each tool joint or coupling OD.
The allowable torque also changes with the gripping diameter and jaw arrangement. A larger jaw does not always carry the same rating as a smaller one. Operators should therefore follow the confirmed jaw and torque chart for each setup.
Type B tongs commonly support drill pipe makeup and breakout, casing coupling connections, drilling sub assembly and workover rig tubular handling. They also provide practical backup when powered rig floor equipment becomes unavailable.
Buyers can choose a standard or extended lever. An extended lever may reduce the required line pull, but it needs more floor clearance. It does not increase the rated capacity of the tong body, installed jaw or suspension system.
Type DB Manual Tong for Heavy Tubulars
The Type DB Manual Tong offers a larger gripping range and higher torque capacity than a standard Type B model. Drilling contractors often select it for heavier tubulars and connections that need more breakout force.
Common applications include heavy drill pipe, drill collars, casing couplings, crossover subs and selected bottom-hole assembly components. Depending on the chosen configuration, Type DB tongs may cover gripping diameters up to approximately 17 inches.
The Type DB family uses several lug jaw, latch jaw and hardware combinations. As a result, one tong fitted with one jaw set cannot handle every listed diameter. The crew must use the correct jaw arrangement for each tool joint, coupling or drilling tool.
For accurate selection, state the actual gripping OD, connection type, makeup torque and expected breakout torque. The nominal pipe size does not identify the correct jaw or confirm the allowable operating load.
Type C and Type LF Workover Manual Tongs
Type C and Type LF Manual Tongs suit small and medium tubulars on workover rigs, well servicing units and compact drilling floors.
The Type LF Manual Tong works well with production tubing, small drill pipe and lower-torque workover connections. Its compact structure also helps where limited floor space restricts lever movement.
The Type C Manual Tong covers a broader gripping and torque range. It can handle tubing, small drill pipe, light casing and selected service tools. This flexibility makes it useful for contractors who want one tong body for several workover applications.
Typical jobs include production tubing installation, tubing pulling, completion string assembly, downhole pump service and light casing work.
For tubing selection, send both the tubing body OD and coupling OD. The coupling usually has a larger outside diameter and often determines the required jaw.
Type H and Type SDD Higher-Torque Manual Tongs
Type H and Type SDD Manual Tongs serve connections that need more torque than standard general-purpose models.
The Type H Manual Tong handles selected drill pipe, tubing and casing connections. Its allowable torque changes with the installed lug jaw and gripping diameter, so crews must follow the correct jaw chart for each application.
The Type SDD Manual Tong supports larger drill pipe, heavy casing, drill collars and drilling tools. Selected configurations can reach a maximum rated torque of 100,000 ft-lb.
Because these tongs transfer substantial force, operators must review the complete rig floor arrangement. The tong body, jaw, lever, hanger, pull line, snub line and torque-measuring system must have compatible ratings. The lowest-rated component sets the operating limit.
Typical applications include high-torque drill pipe makeup, difficult breakout work, heavy casing connections, drill collar handling, stabilizer connections, drilling jars and heavyweight drill pipe.
Type AAX, WWB and Web Wilson Style Manual Tongs
Type AAX, Type WWB and related Web Wilson Style Manual Tongs provide additional options for drilling, workover and casing operations.
The Type AAX model commonly handles drill pipe, casing joints and couplings. Operators adjust its gripping range by changing the lug and latch jaw arrangement.
The Type WWB Manual Tong suits drill pipe, tubing and casing within its confirmed size and torque limits. It offers a practical choice for many workover rigs and well servicing units.
Jaw dimensions, pin locations and part numbers may vary between manufacturers. Buyers should therefore avoid ordering replacement jaws from the model name alone. The existing nameplate, part number, dimensions and clear photographs allow a more reliable compatibility check.
Large-Diameter Casing Manual Tong
A large-diameter casing manual tong uses a dedicated tong head and jaw arrangement for casing couplings, large casing strings and conductor pipe.
A standard drill pipe tong may physically close around a large tubular. However, that does not confirm suitable jaw geometry, load transfer or torque capacity. Large casing operations usually require a purpose-built casing tong that grips the coupling correctly.
SGPE can review requirements for surface casing, intermediate casing, production casing, conductor pipe, casing repair and tubular recovery work.
For model selection, send the casing body OD, coupling OD, required makeup and breakout torque, available floor space and suspension arrangement. These details allow SGPE to check the tong head, jaw package, lever length and rated capacity.
How Does a Manual Drilling Tong Work?
A manual drilling tong converts pull-line force into rotational torque.
First, the crew installs the correct jaw set and positions the tong around the approved gripping area. The latch closes the tong head and keeps the jaws engaged.
Next, a rig catline or controlled pull line applies force to the lever. A backup tong or another approved holding device secures the opposite side of the connection. This arrangement allows the tong to apply makeup or breakout torque.
The effective lever length, line pull and pull angle all affect the final torque. Operators must also follow the tong rating, jaw limit, connection torque recommendation and rig procedure.
Unlike a hydraulic power tong, an oilfield hand tong does not use a hydraulic motor or powered gearbox. Its straightforward mechanical structure makes it useful on conventional rigs, at remote drilling locations and as emergency backup equipment.
Typical Torque and Line-Pull Relationship
The following values assume that the pull line remains perpendicular to the tong lever.
| Effective Lever Length | Line Pull | Theoretical Torque |
| 3 ft | 5,000 lbf | 15,000 ft-lb |
| 3 ft | 10,000 lbf | 30,000 ft-lb |
| 4 ft | 5,000 lbf | 20,000 ft-lb |
| 4 ft | 10,000 lbf | 40,000 ft-lb |
| 5 ft | 5,000 lbf | 25,000 ft-lb |
| 5 ft | 10,000 lbf | 50,000 ft-lb |
The general relationship is:
Torque = line pull × effective lever length × sin θ
Here, θ represents the angle between the lever and the pull line. At 90 degrees, sin θ equals 1. As the angle moves away from 90 degrees, the effective torque decreases.
This calculation does not increase the approved rating of the tong, jaw, pull line, hanger or suspension system. Always operate within the limit of the lowest-rated component.
Main Oilfield Applications
Drill Pipe Makeup and Breakout
A drill pipe manual tong tightens or loosens rotary-shouldered connections during drilling, tripping and stand-building operations.
The tong should grip the approved tool joint area rather than the thinner drill pipe body. Correct positioning improves grip and reduces the risk of surface damage.
Tubing Running and Pulling
A tubing manual tong supports production tubing installation, tubing pulling, completion work and well servicing.
Type MS, LF and C tongs often suit smaller tubing connections. However, final selection still depends on the coupling OD, thread type and required makeup torque.
Casing Running
A manual casing tong handles casing couplings during surface, intermediate and production casing operations.
Large casing sizes usually require a dedicated casing tong head rather than a standard drill pipe tong.
Drill Collar and BHA Connections
Type DB, H and SDD tongs can handle selected drill collars, heavyweight drill pipe, stabilizers, drilling jars, crossover subs and other BHA components.
These connections may require high torque. Therefore, buyers should state both the actual gripping OD and the required connection torque.
Workover and Well Servicing
A workover manual tong supports tubing pulling, downhole pump service, completion string work, fishing operations and production equipment maintenance.
Its mechanical design also allows service crews to replace jaws, dies, pins and springs at the rig or maintenance base.
Backup Rig Floor Service
Many drilling contractors keep an oilfield manual tong as backup for a hydraulic power tong or iron roughneck.
Before use, the operator must confirm that the tong, pulling lines, suspension and operating procedure suit the required torque.

| Gripping Surface | Identifies the approved tong area |
| Makeup Torque | Helps confirm tong and jaw capacity |
| Breakout Torque | Defines the expected maximum operating load |
| Tong Model | Determines compatible jaw geometry |
| Existing Jaw Number | Helps match replacement parts |
| Lever Length | Affects line pull and floor clearance |
| Rig Floor Space | Limits the practical tong arrangement |
Manual Tong Jaws and Tong Dies
Interchangeable manual tong jaws allow one tong body to handle several tubular sizes. However, changing the gripping diameter may require more than a new set of tong dies.
Depending on the model and target diameter, the crew may need to change the lug jaw, latch jaw, hinge jaw, long jaw or short jaw. Some configurations also require different jaw pins, latch hardware or hinge positions.
Larger jaws may carry lower torque limits because the load path changes with the gripping diameter. For this reason, operators should check the confirmed jaw and torque chart before use.
For replacement parts, send SGPE the tong manufacturer, model, serial number or nameplate. The current jaw number, part number, actual gripping OD and clear photographs will help our technical team check compatibility.

Frequently Asked Questions About API 7K Manual Tongs
1. What information should I provide when requesting an API 7K Manual Tong quotation?
State the tubular type, nominal size and actual gripping OD. For drill pipe, use the tool joint OD. For tubing or casing, confirm whether the tong will grip the pipe body, coupling or another approved area.
You should also include the connection type, makeup torque, expected breakout torque, required jaw sizes, lever preference and quantity. Add any API, inspection, documentation and delivery requirements.
For replacement work, send the existing nameplate, jaw number, part number, photographs and critical dimensions.
2. How do I choose the correct manual tong size for drill pipe?
Select a drill pipe tong from the actual tool joint OD rather than the nominal drill pipe body size. Two pipes with the same nominal diameter may use different tool joints, connections and torque values.
Type B and Type AAX tongs often suit standard drill pipe. Type DB, H and SDD models cover larger tool joints or higher-torque connections.
Share the drill pipe size, tool joint OD, connection, makeup torque and expected breakout torque so SGPE can match the correct model and jaw package.
3. What is the difference between Type B and Type DB Manual Tongs?
Type B Manual Tongs serve general drill pipe, casing coupling and drilling sub connections. They offer a practical range for conventional drilling and workover operations.
Type DB models provide a larger gripping range and higher torque capacity. Contractors often use them for heavy drill pipe, drill collars, larger casing couplings and selected BHA components.
The installed jaw and gripping diameter still determine the final torque limit. For that reason, buyers should compare the complete configuration rather than the model name alone.
4. Which manual tong suits tubing and workover operations?
Type MS, LF and C Manual Tongs commonly suit production tubing, completion work and light workover service.
Type MS and LF models cover smaller diameters and lower torque requirements. Type C offers a wider gripping range for tubing, small drill pipe, light casing and selected service tools.
Confirm the tubing body OD, coupling OD, thread type, makeup torque and available floor space. In many cases, the coupling OD determines the required jaw.
5. Can SGPE supply a manual tong for casing and conductor pipe?
Yes. SGPE can supply casing manual tongs for surface casing, intermediate casing, production casing and conductor pipe.
Large sizes usually require a dedicated casing tong head. A standard drill pipe tong may close around a coupling, but that does not confirm suitable jaw geometry, load transfer or torque capacity.
Send the casing body OD, coupling OD, required torque, floor clearance and suspension details for technical review.
6. Can one API 7K Manual Tong handle several tubular sizes?
One tong body can often handle several diameters by using different lug jaws, latch jaws, hinge jaws and tong dies.
However, one jaw set cannot cover the complete model range. Some size changes also require different pins, latch hardware or hinge positions. Larger jaws may also carry lower torque limits.
List every required gripping OD so SGPE can prepare the correct multi-size jaw package.
7. Why is the actual gripping OD more important than the nominal pipe size?
A manual tong often grips a tool joint or coupling rather than the tubular body. These sections usually have a larger outside diameter.
For example, a 5-inch drill pipe may use a much larger tool joint. Tubing and casing couplings also exceed the pipe body OD.
Measure the exact gripping surface and identify whether it is a tool joint, coupling, drill collar or pipe body. This information helps prevent jaw fitment errors.
8. How do lever length, line pull and pull angle affect torque?
A manual tong converts line pull into torque through its lever. A longer lever can reduce the pull force required for a given theoretical torque, but it also needs more floor clearance.
The highest theoretical torque occurs when the pull line remains perpendicular to the lever. As the angle changes, the effective torque decreases.
An extended lever does not raise the rated capacity of the tong body, jaw, hanger or suspension system.
9. Can SGPE supply manual tong jaws, dies and replacement parts?
Yes. SGPE supplies lug jaws, latch jaws, hinge jaws, long jaws, short jaws, tong dies, pins, springs, plungers, hanger components, lever parts and retaining hardware.
For accurate matching, send the manufacturer, model, serial number, nameplate and existing part number. Clear photographs and actual dimensions help when the original identification is missing.
Different manufacturers may use different jaw profiles and pin positions, even when the model names appear similar.
10. What is the difference between a manual tong, hydraulic power tong and iron roughneck?
A manual tong uses a catline or mechanical pull line. Its straightforward structure suits conventional rigs, occasional use and backup service.
A hydraulic power tong uses a hydraulic motor and gearbox. It operates faster during repetitive tubing or casing running.
An iron roughneck combines clamping, spinning and torquing in one powered system. It suits high-volume drill pipe handling but requires more floor space and technical support.
11. Does every API 7K Manual Tong carry an API Monogram?
No. API Spec 7K includes manual tongs, but the product name does not confirm API Monogram marking.
Monogram eligibility depends on the selected product, manufacturing source and active licence scope. State the required API marking in both the RFQ and purchase order.
SGPE will review the requirement before order confirmation and align the marking and document package with the agreed scope.
12. What inspection documents and export services can SGPE provide?
SGPE can provide an agreed package with a COC, MTCs, dimensional reports, hardness results, MPI reports, functional records, data sheets, jaw charts, torque charts and operation manuals.
We can also coordinate third-party inspection according to an approved inspection and test plan. Buyers should confirm the inspection agency and hold points before production.
For export orders, SGPE can arrange corrosion protection, project marking, plywood cases, seaworthy packing and packing photographs.
