How to Choose Bolt Stretcher

To choose bolt stretcher depends on the stretching mode first, the required pretightening force Kn, and then the torque mode, and the required tightening torque Nm. Bolt stretching is to use hydraulic cylinder to exert external force on the bolt end, stretch the bolt to the required length, and then tighten the nut, so that [...]

Maintenance of Hydraulic Stretcher

Hydraulic stretcher must be operated strictly according to the method and procedure required in the instructions. The input working pressure and stretching length of the hydraulic stretcher can not be increased at will, so as to avoid damaging the sealing ring and the related mating parts. After the hydraulic bolt tensioning tool is finished, it [...]

Advantage of Hydraulic Bolt Stretcher

Our hydraulic bolt stretcher can quickly and safely synchronously stretch bolts. They can apply force to each bolt evenly and permanently. If the bolt is not properly stretched, it will not work properly. For the connection combination, accurate stretching combination is the key. Hydraulic bolt tensioner reduces this risk. Precise calculation of preload can avoid [...]
