Hydraulic bolt tensioners are used in the process of achieving preload, which involves axially stretching the bolt using hydraulic nuts or detachable bolt tensioners. Hydraulic bolt tensioning eliminates fictional inaccuracies and uses hydraulic pressure to generate torque. Preload is the internal stress applied to particular components in mechanical systems. Preloading is important as it increases the efficiency of a machine and makes it resistant to external factors and serves as a limit for the amount of load that a system can handle. Hydraulic bolt tensioners simultaneously work on multiple studs by applying a uniform a load. The hydraulic bolt tensioned sequentially connects the tools
through a high-pressure hose into a single pumping unit. The sequential connections make sure that every tool generates an equal torque amount for uniform clamping. The stud acts as a fitting base for the belt tensioner, which stretches the stud when hydraulic pressure is applied on it, which winds the stud into the face of the joint.Get the best choice of hydraulic bolt tensioners and accessories available in the market today.
