Feature of ST series bolt tensioner:
1. ST Series Bolt Tensioners are designed for critical fastening applications in wind, steam and gas turbines.
Why You Need Hydraulic Tensioner?
The bolt tensioner uses pure tension to directly elongate the bolt, without torsion shear and lateral force, and no frictional damage to the contact surface. It is the best method to accurately control the bolt pre-tightening force. Compared with hydraulic torque wrenches, bolt tensioners have the advantages of rapid response and accuracy, no torsional stress, no frictional damage, and simultaneous pre-tightening of multiple bolts. The bolt tensioner can be used singly, or multiple tensioners can be used in parallel, which can not only improve efficiency, but also ensure the uniformity of the force of multiple bolts. When the bolt center distance is small and the radial size is restricted, a two-stage structure can also be adopted, and the axial size is sacrificed to ensure the radial size. In the case of the same outer diameter, the effective area of the piston is doubled, and the force generated is doubled.
The disadvantage is that it needs enough screw elongation, which will be very limited in the case of narrow axial space.
