There are two such equipments: the torque wrench and the tube removal equipments which are known as great contributors to a number of processes in the industries. Only the operators know how to manage these devices and what is their significance.

The Device : Torque Wrench and Tube Removal

A torque wrench is a tool which is used to apply a twisting force of a specific kind to a nut or a bolt. It is used when the tightness of screws or bolts is crucial, and the tool helps the operator to measure the force applied to fasten the same. The torque wrench, therefore, helps to maintain the needed tension in the specific parts enabling the operator to assemble it as well. The torque screwdrivers and wrenches have basically the same functions, purposes, and mechanisms. Torque wrenches are of types which are divided into classes. The types are indicating and setting torque wrenches which are divided into class A, B, C, D, E, F, G, etc. The torque wrench suppliers are available both online and offline. While buying torque wrenches from the suppliers, you must see if the product is ISO marked. ISO is an International organization for standardization which covers the construction of the torque wrench, and the calibration of the hand operated torque tools. The important advantages of this product are that they are accurate if they are properly calibrated. You can also use the cheater bars to extend the handle end of the wrench, but it is advisable not to use these extensions.

The tools for tube removal are a part of tube removal system which detaches tube without any damage to the tube sheet and in less time and labor. Tube removal tools can be divided into a number of types like air and hydraulic stub puller, continuous hydraulic tub pullers, master tugger hydraulic tube puller, auto-stub puller, manual tube puller, etc. It also comprises some other tube removal tools and cutters. They are easy to operate and quite effective when it comes to the performance.

Where to buy these devices?

You can opt for two ways if you want to purchase these devices. The first one is to buy them from regular shops and the second one is to buy them online. But in both ways, compare the prices of the products according to the brands and make sure that the tools are ISO marked. In the case of torque wrenches, they need to be properly calibrated for best usage. The products must conform to international quality and standards. If you are new in this field and want to buy it for personal used they go through the feedbacks and ratings on the internet.

In the industry, there are numerous machines in different industries that help to carry out different activities related to production and other important processes. There are lots of industries where thousands of machines are used. In each of these machines, lots of nuts and bolts are used that hold various parts of machines which are important to carry out different processes. For an operator to have the machine in a perfect condition is very important. He needs to carry out maintenance activities at a regular interval that can help to get the processes done in its true sense.

The device:

The wrench which is used to fix the nut and bolt is a great help to the operators who need to run the machines. To fix the nuts and bolts for moving the machine are of great importance. They need to be removed or fixed as and when necessary for the process as well as the maintenance. The torque wrenches manufacturers offer many useful devices that can help the operators to provide the exact amount of torque to fix or remove the nuts and bolts. They are made with scientific designs and provide tremendous quality of work when it comes to applying the torque to the concerned machine. They are made of best quality material alloys which can offer complete value for money spent on them. Hence, with the help of this tool one can apply the right amount of torque to fix the nuts and bolts and run the machine smoothly.

A torque wrench is the best device that eases the task of fixing the nuts and bolts. For every machine, the proper amount of torque on nuts and bolts is much required and hence the user needs to fix the nut and bolt in a manner that the machine can work perfectly. A bolt or nut fixed with much torque can pressurise the machine, and hence the machine cannot function perfectly. If the torque is less than required, the parts may not move as per expectation, and hence it can affect the production capacity again. Therefore, it is much important to fix the machine nuts and bolts as per the required amount.

Application of the device and availability of the same:

The manual application of torque may not be that much accurate, and hence the use of the automatic torque wrench can be much helpful.

The user can get the same from the local market as in themajority of the cities; there are lots of quality shops that sell such devices. One can also check the same in the online stores also. The manufacturers of the device also sell them on their site where the probable buyer can check the description as well as images and see if he wants to go for the same. One can easily place the order on such sites and ask the delivery of the same at the doorstep.

Different Types of Torque Wrenches

The tool used specifically to tighten nuts and bolts to the correct amount, we call as a torque wrench. This helps the worker from over-tightening the nuts especially of the steam pipes and mains of the water system. Using a torque wrench, an operator can measure the amount of torque he or she applies while tightening.

Method of application

By tightening all the nuts by the same amount, one can make sure the system load is uniform and thus the stress distribution is even. However, the drawback in this system is that some nuts may have extra friction on the bolt and this will show up as extra tension. The measurement of the bolt tension will provide the most accurate reading but since one cannot always do this, one must resort to measuring the nut torque.

Different Types of Torque Wrenches

One sees torque wrenches manufacturers make several types of wrenches. The most popular ones are these:

1. Adjustable Click Torque Wrenches: These use a calibrated clutch mechanism to measure the torque. Most common method is the spring-ball system. Here the ball is held in tension by a spring. You find the tension graduation in torque units. By setting the reading to the desired value, the spring pushes until you reach the value. At this point, the ball release takes place and the tension disappears. This is simple and accurate. One finds it safe to use.
2. Square Drive Torque Wrenches: We use this torque wrenches to get consistent torque output. These have 360° swivel manifold with couplers of the screw lock type. You can prevent lock-on on tool by providing fine ratchets. The advantage of this type of wrench is reliability, safety, and durability. They have lesser moving parts and a faster stroke. You get accurate repeatability with this. If needed, you can also perform hands-off operation.
3. Beam Type Torque Wrenches: In this type of torque wrench, two beams come into play. The first one is a handle that serves as a lever for applying the torque. The second one bends in proportion to the torque applied. The scale at the end of the beam will show how much torque we apply at any point of time. The advantage of this type of wrench is the simplicity. The equipment is light and the readings are accurate. If you want more accuracy, you can mount a dial gauge on the beams to get the reading.
4. Slipper Type Torque Wrenches: This type of torque wrench has cam and a roller. We attach the driver to the cam while the roller pushes against it, locking it in place. We can adjust the pressure point in this manner to a prescribed value so that when we reach that point, the cam will roll and the roller will slip, and the nut tightening will stop. In this way, we tighten the nut to the set value and not beyond.
5. Programmable Wrenches: These use an angle measurement gyroscope and electronic torque wrench reading mechanism. Since the torque measurement is in-situ, one can analyse points of stress where we have final torque, prevail torque, and breakaway torque. At the same time, the angel of tightening is always monitored. You require this kind of mechanism in automobile parts tightening to maintain constant stress in all the parts.

Ask yourself, “How often do you use this wrench?” The answer for this question lets you decide on the amount you can spend on the wrench.

Get The Perfect Turn..!!!

When you are dealing with assembling, manufacturing or servicing operations, a must have tool in your kit is a torque wrench. They are meant to apply a specified torque on the fasteners so that they don’t stretch or break due to over load nor come out loose due to under torquing. The applications of the torque wrench include fasteners of vehicles, ball joint studs, axle nuts, lug nuts, intake exhaust manifold fasteners, fly wheel bolts, crankshaft pulley bolts, cam shaft timing gear bolts and many more. Before you approach torque wrench suppliers, have a quick look at this.

Why Use A Torque Wrench…?

The twisting force on any object is termed as torque. Best results can be obtained only when you apply the desired torque level on the fasteners.

• These tools can enhance the performance of your vehicles. If the wheels of your vehicle are improperly torqued, there are good chances that it can result in a disaster. This problem magnifies in case of heavy vehicles. One has to understand that the over torquing is equally undesirable as under torquing.

• Applying excess torque on the fasteners can strip the lug nuts or wrap rotors. It also induces significant amount of strain on the lugs, which results in their breakage. Lugs come out loose when you under torque them. The result is that the wheels fall off..! The magnitude of the problem caused by this can be imaginable.

• The torque wrench enhances the abilities of the fasteners, thus resulting in increased quality and reliable safety of the application. Tightening the bolt to undesired levels can result in breakage of the fastener and thereby can also damage the application.

When you are using a torque wrench, you must calibrate it regularly. Failing to do so, the quality of the work performed might come down. There are many factors like the temperature changes, stresses induced and others which increase the need to calibrate the tool.

Types Of Torque Wrenches:

• Bending beam: If you don’t have the need to use a torque wrench very often, then prefer this type. When you apply the torque, the beam at the centre rotates, moving the pointer to move over a calibrated scale. Here, the amount of torque applied can be read directly. Beware of parallax error while using this device.

• Micrometer clicker: If you are dealing with large assemblies, prefer a clicker type of torque wrench. It eliminates the need to check the pointer for every single use. It generates a click sound which is loud enough to hear as the torque applied reaches desired levels. If you are using it parts like internal engine fasteners and suspension, make sure to calibrate them regularly.

• Dial gauges and digital electronic torque wrench: These devices are the most advanced and accurate than other types. The digital indicator displays the torque applied. Talking about the price of these wrenches, they are just too expensive..! However, they are the best choice when you are dealing with racing cars and NASCAR engines.

The Perfect Turn with Torque Wrenches…!!!

Torque wrench – Highly Efficient yet Under Appreciated Tool…!!

In this fast paced industrialized world, manufacturing and maintenance processes play a dominant role in many sectors. The key aspects of these processes are tightening and controlling different types of fasteners. However, in handling such jobs, care has to be taken that we deploy the accurate amount of torque on the fasteners. Applying lower torque results in vibration of the fasteners. Higher torque application can break the fasteners. So, the precise range of torque should be employed. To accomplish this task, torque wrenches have evolved. They help us in applying only required amount of torques.

Types:

Torque wrench manufacturers come up with different types aiming at varied applications. Yet, a few basic types are listed below:

• Click type / setting torque wrenches: In this type of wrenches, the torque has to be set prior to the start of work. They are generally calibrated. It responds when the desired torque reaches by either changing its geometry physically or by a click.

• Indicating torque wrenches: As the name suggests, it indicates the value of the torque applied by the operator either mechanically (ex: dial gauge) or displays the value through electronic systems.

• Torque screw drivers: When it comes to handling smaller torques, the above mentioned torque wrenches may not be effective. It’s then, these torque screw drivers come into picture. Excluding this part, the other issues remain similar to that of other types.

Calibration of Torque Wrenches:

• While calibrating, temperature and other environmental conditions have to be considered strongly. A record of these values has to be maintained.

• In this context, it is recommended to operate the instrument in the same plane of its position. If the wrench is positioned in horizontal plane and then pushed down, the calibration obtained may not be perfect as the self weight of the wrench can bring out considerable impact on calibration.

• The readings should be taken at distinct points of the torque wrench range.

• A few wrenches have the mechanism which facilitates the operation in two different directions. However, calibrating such types is not easy.

A Few Tips:

• The types of the torque wrenches are versatile. Hence, before actually choosing it, one has to read the instructions manual of the instrument. Select it only if you feel that it can justify your requirement.

• The scales of many of these instruments can be adjusted. Make a note of it.

• The accuracy of the torque wrenches varies with the type. Select the one whose accuracy range can fit into the desired application.

Maintenance:

• For effective functioning of the instrument, it has to be inspected periodically.

• If the wrench looks to be worn out excessively, it has to be serviced.

• Store the instrument in clean and dry place. It has to be protected from dust,

• chemicals and other impurities.

• Never use the cleaning fluids which result in the corrosion of the material.

• Torque wrenches which use a spring must meet a linear capability test.
