Discover the Best Torque Equipment Available for Your Needs
What is torque?
Torque is the measurement of how a force is causing an object to rotate. For our purposes, torque is the foundation for secure, safe bolting. Beyond torque, there is torque control, torque tensioning and other practical applications that apply to bolting. Torque, simply, is important
Hydraulic Torque Equipment Overview
There are a variety of tools available for petrochemical, oil and gas, wind generation, construction, maintenance and power generation companies to utilize on their bolting projects. While not all are required on every site, hydraulic torque equipment includes:
- Torque wrenches
- Flange tools
- Torque measurement & calibration devices
The hydraulic and pneumatic torque wrenches required for heavy-duty bolting applications are considerably larger and more powerful than the simple click or beam torque wrenches you likely have in your personal toolbox.
For instance, the Enerpac S-Series Hydraulic Torque Wrench delivers 25,140 ft/lbs of torque while the DSX 3000 Enerpac DSX Torque Wrench is able to accurately apply torque with an accuracy of +/3% and has a fully-enclosed drive with a built-in safety tether so that it can be used on elevated projects.
Hydraulic Bolt Tensioners
When it comes to applying tension on bolts, it’s vitally important that you accurately measure your output for safe and secure seals. Having a top-of-the-line hydraulic bolt tensioner provides peace of mind and faster application than torque wrenching.
With a product like the Enerpac GT-Series Hydraulic Bolt Tensioners, your team can evenly distribute tension across all bolts on a flange simultaneously and safely since you are working with a hydraulic system – including a powerful, accurate pump – that doesn’t require hands-on tightening.
Friction points and the importance of lubrication
Friction points are where the torque is lost due to friction. This is more easily understood as the touching threads between a nut and a bolt and whatever material the bolt is clamping. Without knowing your friction points, you won’t know how much torque should be applied and how much will be lost from friction.
Anywhere from 80 to 90% of your torque will be lost to friction, but we can reduce friction through lubrication. With proper lubrication, you are able to reduce friction, providing more torque to the preload and removing stress from the bolt through the process. You’ll decrease your chances of bolt failure during installation as well as extend its life.
To make sure that you apply the right amount of lubrication to reach your desired preload, manufacturers provide the value for the friction coefficient.
While having the right hydraulic torque equipment and tensioners is necessary for a properly executed project, it’s the unfortunate truth that you will hit speed bumps along the way. Tools such as nut splitters, flange spreaders, and flange aligners can help you ensure that frozen bolts or misaligned flanges don’t eat up huge chunks of your project timeline. Keep them on hand, or risk missed deadlines and mounting turnaround costs.
Torque Measurement and Calibration
When dealing with the required accuracy of a bolting project, you need to make sure that your torque equipment is properly calibrated and measuring precisely. Stay in the know with a suite of transducers and instruments for any environment or application, so that you can be certain your tools are handling the job properly.
Renting and buying
We understand that the cost of purchasing a new piece of torque equipment isn’t always practical, especially if you’re a smaller company with limited overhead, you just plan to use the tool for one project or you need a quick replacement for a broken tool.
At Aztec, we offer rentals for a wide variety of tools from industry brand leaders so that you have the right torque wrench, hydraulic pump or nut splitter for the job in front of you. And if you decide that your rental equipment is too good to send back to us, we have lease-to-own options that give you even more flexibility for your torque equipment needs.
