Safety First: Manual Tongs vs. Hydraulic Options
Safety regulations should apply to both manual and hydraulic tong operation. The two systems operate differently, and the corresponding risks and controls are likewise different. Manual Tongs do not need a hydraulic power circuit but do require correct gripping, placement, handling and operator practices.
The API Spec 7K explicitly addresses manual tongs within the ambit of drilling and well service equipment and establishes rules for the design, production, and testing of such equipment. (API Spec. 7K)
Reduced Complexity, Increased Reliability
Manual tongs are mechanically made, rather than hydraulically powered. The primary working idea is that the tube is gripped by the jaws and dies and torque is applied by a handle or lever arrangement.
This less complex working mechanism may be beneficial if a hydraulic power source is not accessible or not needed. It also implies that maintenance is more about mechanical components like jaws, dies, pins, latches and other moving parts than hydraulic circuits.
However, simpler construction does not eliminate the necessity for inspection. Wear, broken parts, wrong die selection and wrong operation may still impact performance and safety.
Enhanced Control and Precision
The manual tongs enable the user to exert the force directly via the mechanical construction of the tool. This may be beneficial for situations where the operator has to manually regulate the make-up or break-out procedure.
The exact torque that can be produced depends on the tong design, handle or lever configuration, tubular size and working mode. It should thus be adapted to the connection needs rather than inferred from the physical size of the instrument .
This variety is represented in Welong’s product range. The published models are available with various maximum torque capabilities, (27, 48, and 75 kN·m depending on the type).
Lower Risk of Hydraulic-Related Accidents
The Manual Tong does not employ the hydraulic power circuit used with hydraulic tong equipment. Thus, hydraulic-fluid leakage and hydraulic-system pressure are not part of the tong's operational mechanism.
This should not be taken to infer that manual usage of the tongs is by definition safer. Operators must still regulate stored mechanical force, pipe movement, tong location, gripping and handle movement.
Therefore, safe operation relies on the right tong selection, the gripping components being in adequate condition and on compliance with the manufacturer’s operating and maintenance regulations.
Versatility in Challenging Environments
Manual Tongs may be helpful in situations where a relatively basic mechanical tool is required. They do not need a hydraulic power unit or an electronic control system to provide the fundamental grasping and torque function.
This might be beneficial in distant or smaller enterprises when equipment availability and system simplicity are critical concerns. But environmental variables like corrosion, pollution, temperature and mechanical wear may still impair the quality of equipment. These still need proper maintenance, cleaning, lubrication and storage.
Maintenance Tips for Prolonging Manual Tong Lifespan
The service life of Manual Tongs is very much dependent on the manner in which the equipment is worked, inspected, lubricated and stored. A maintenance programme must be in accordance with the manufacturer’s instructions and the appropriate inspection requirements for the equipment.
API RP 7L offers methods and instructions for the inspection, maintenance, repair and remanufacture of drilling equipment. The scope of this document includes manual tongs.
Regular Inspection and Cleaning
Before using, inspect the manual tong for any apparent damage, excessive wear, deformation, damaged jaws, worn dies, loose components or any other condition that may impact operation.
Cleaning is also necessary if the instrument has been exposed to drilling mud, grime or other pollutants. Cleaning out the build-up makes it easier to see damage and helps maintain moving parts serviceable.
Any component that does not meet manufacturer criteria should be inspected before the tong is restored to service.
Lubrication is Key
The mechanical parts in motion need proper lubrication to reduce friction and wear. The maintenance instructions supplied by the manufacturer will specify the right lubrication and where it should be applied.
Lubrication is no alternative for examination. Even a well oiled tong may be dangerous if its dies, jaws, pins or structural components are broken or worn beyond acceptable limits.
Proper Storage
Keep Tongs in a state that helps reduce corrosion and contamination while not in use. The equipment should be protected from unnecessary exposure to moisture, dirt and corrosive elements.
Operators should follow the manufacturer’s instructions for cleaning, lubrication and protection before storage for lengthy periods of time. Correct storing also lets you know the state of the tool before you use it again.
Timely Replacements and Repairs
Worn or damaged components should be repaired or replaced in accordance with manufacturer’s guidelines. Specifically, gripping elements like dies must be adapted to the tubular size and the working demands.
Appearance should not be the main factor in repair choices. Load bearing or critical parts should be evaluated in accordance with the appropriate procedures before reinstatement to service.
Partnering with an existing Manual Tongs manufacturer helps ease the process of securing the proper replacement parts and technical data.
Training and Proper Use
For Manual Tongs accurate operation by the operator is essential. Personnel should be familiar with the intended use of the tong, the way to grasp, restrictions of operation and proper handling of the equipment before use.
Training should also include the proper tong size and die selection for the tube being handled. Improper tongs or use of force outside the working limits may adversely harm equipment condition and quality of connection.
Routine refresher training may assist to ensure consistent operating techniques, especially when multiple types of tongs are used in drilling, workover or well-service tasks.
ROI Analysis: Manual Tongs in Small-Scale Operations
The economic worth of Manual Tongs should be assessed based on the real operational needs rather than using the lowest purchasing price as a guaranty of the greatest return.
In smaller operations, considerations such as cost of equipment procurement, maintenance needs, labour requirements, working frequency, necessary torque, tube size, and availability of powered equipment may be significant.
Initial Investment Comparison
Manual Tongs provide a very simple setup since there is no need for the hydraulic power unit that is a need for the hydraulic tong system.
However, a fair cost comparison can be made only with project-specific price and operational data. The purchasing price of the tong is a portion of the overall equipment cost.
Buyers should examine the actual equipment configuration needed for the application including supporting equipment, replacement parts, inspection requirements and operator needs.
Operational Cost Savings
The running costs of a Manual Tong depend on how often it is used and how the process is organised. In applications not requiring powered tong operation, a simplified equipment design is available, as the tool requires just mechanical force and not a specific hydraulic power source.
Maintenance needs must also be taken into account. Mechanical parts still need to be checked, lubed and replaced when worn out.
Hence, promises of decreased operating costs need to be weighed against the real labour, maintenance and equipment needs of the business.
Longevity and Durability
A Manual Tongs well picked and maintained may be beneficial throughout a long time of service. Durability is a function of tool design, material and quality of manufacture, working circumstances, operating methods and maintenance.
Welong’s current product line comprises a wide variety of manual tong configurations for various tubular diameters and applications. It lets the consumer to choose a tool to match the operating range needed, rather than one general-purpose model for all operations. (Manual Tong Welong)
Thus, long-term value dictates that equipment compatibility and maintenance needs should be taken into account instead of a predetermined service life assumption.
Versatility and Adaptability
Manual Tongs are offered in a number of designs for various tubular applications. Welong’s published line comprises Type SDD, DB, SB, B and C Manual Tongs, Casing Tongs and Well-service Tongs. The types shown provide for various sizes of handle and varying torque capabilities.
This range enables customers to pick equipment according on the tubular outer diameter, connecting requirements and torque needed.
The important thing to remember; versatility does not imply every tong can handle every pipe size. Always examine the advertised functioning range of the model before you choose it.
Training and Skill Development
Operator expertise has a big role in the whole value of Manual Tongs. The equipment must be properly positioned and gripped and the Force and Handling Procedures must be followed.
Training is consequently part of the running expense, but it may also encourage consistent usage of equipment, and can assist to decrease needless damage caused by wrong operation.
When comparing Manual Tongs versus powered options, firms should analyse the whole workflow including the equipment itself, the operator needs, maintenance and the planned frequency of use.
Conclusion
Manual Tongs are a realistic alternative for oilfield applications where mechanical operation is suitable, and a powered tong system is not needed. They are valuable because of the combination of relatively basic mechanical construction, varied possible configurations and the ability to perform specialised tubular make-up and break-out activities.
But cost efficiency should not be measured by purchasing price alone. Overall value of a Manual Tong is dependent on tubular size, torque needs, frequency of operation, maintenance, labour and equipment compatibility.
Welong’s published range covers many Manual Tong kinds with a variety of handling size and maximum torque capacity. Users may pick equipment according to real application. (Welong Manual Tong)
For procurement teams, the most practical strategy is to first establish the tubular size, necessary torque, application and operating circumstances, then evaluate suitable tong designs and their related ownership needs.
FAQ
1. What are the main advantages of using manual tongs in oilfield operations?
Manual tongs are a mechanical means of grabbing tubulars and delivering torque during make-up and break-out operations. They do not need the hydraulic power circuit required for hydraulic tong systems, which makes them acceptable for situations where a simpler mechanical set-up is desirable.
They are nevertheless subject to tubular size, torque requirements, operating circumstances and operator protocols.
2. How often should manual tongs be inspected and maintained?
Manual Tongs should be examined in accordance with the manufacturer’s recommendations and the appropriate inspection programme. Operators must inspect before to use for evident damage, excessive wear, damaged gripping components, loose parts and other circumstances that may compromise safe operation.
Maintenance, such as cleaning and lubrication, should be performed according to the manufacturer's recommendations, not on a strict weekly or monthly basis. API RP 7L is the guide to inspection, maintenance, repair and remanufacture of suitable drilling equipment including manual tongs. (API RP 7L).
3. Can manual tongs be as efficient as hydraulic options in large-scale operations?
The solution is application-dependent. Hydraulic tong systems are perhaps more suited in high-volume, repetitive or mechanised processes where powered operation is required.
Manual Tongs are still relevant to applications where manual operation is acceptable, such as certain drilling, workover, well-service, remote or backup applications. The comparison should be based on the needed torque, operating frequency, available power systems, labour, maintenance and connection needs, not only the project size.
