      Hydraulic tensioners working principle is to use a hydraulic cylinder is directly applied force to the bolt , the bolt force is applied in its elastic deformation zone is elongated bolt diameter micro- deformation, so that the nut is easy to loose.

      Hydraulic bolt tensioners axis of the mounting position for the bolt axial tension to achieve desired amount of stretching the bolt , and this determines the amount of stretching of the bolt is required for fastening the bolt clamping force . When subjected to tensile bolts , nuts and flange contact surface will come from the open , the lower the hydraulic tensioner has an opening for an operator manually turn the nut , turn the nut is usually through a metal stick to toggle dial outside hex nut a dial ring to achieve ( or direct toggle round nut ) .

      Remove the oil pressure in the hydraulic tensioners , close to the nut and engaging surface , so that the axial deformation of the bolt lock , the bolt is remaining inside the load lock nut .

      so, is mainly used for the hydraulic tensioner bolt setting all kinds of fastening and removal.

      And the hydraulic cylinder is proportional to the load applied to the bolt , this design can be very accurately retain the payload . Since the load is directly applied to the bolt , the bolt and for all forces are stretched , so the load to produce the desired minimum space .

Detailed stretch Features
● stretching mode is not affected by the friction bolt and thread size of the lubricating effect can be obtained more accurate bolt loads .

● You can synchronize multiple bolt tension , so that the entire ring bolt force uniform , get a balanced load.

● As a result of the most advanced ultra-high pressure technology , you can complete disassembly of the bolt in a small space.

● stretching mode of the fastening bolts remaining load was greater than the load torque and effective manner .
● stretching mode is more suitable for joining the fastening applications require high accuracy , which enables the flange to effect engagement by force , actually prevent leakage .
