AD21LS Series Hydraulic Bolt Tensioners,

                  Made to fit where other tools can’t.

With its compact fit and high load generation,
alongside the flexibility to work with all standard flanges

Bolt Range:  M24 - M 100

Standard Working Pressure: 1500 bar

Working Pressue Range: 1000 - 4000 bar

The Hydraulic Bolt Tensioner is designed to provide simple but safe tensioning operations

with the added benefit of speed and reliability. The tensioning tool uses a single chamber

hydraulic load cell to load standard studbolts. In operation, the tensioning tools are

assembled to one or more bolts to be tightened.

The tensioner is placed over the nut and a second nut is screwed down onto the tensioner.

Multiple tensioners can be assembled to a single joint to create simultaneous and uniform

joint compression and bolt loading.

In order to apply load to the bolt, the pump is activated and a predetermined pressure

is applied to the system. As the tensioners apply load to each bolt, the nuts are lifted from

the joint surface as the bolt stretches due to the load. While the tensioner system pressure

is maintained, each of the flange nuts are tightened back down against the joint face.

Upon release of the system pressure, the load is retained/trapped in each bolt.

Check the parameters and confirm the model No.
