Hydraulic bolt tensioners
Tensioning bolted joints without torsion: accurately, evenly and all bolts at once.
A hydraulic bolt tensioner stretches the bolt lengthwise, after which you run down the nut without force. No torsion enters the bolt, and by linking several tensioners you tension all the bolts of a joint at the same time and to the same load.
We supply and rent out bolt tensioners for topside and subsea use and for wind turbines, hydraulic nuts and the matching pumps and hoses. Ask us about the possibilities.
