Hydraulic Tenisoners

Hydraulic bolt tensioners create joint preload by stretching the stud axially before the nut is seated. Belium lists top-side bolt tensioners and wind tensioners, with related accessories and pumps. For a flange or wind-energy joint, the tensioner must fit the thread, exposed stud length and space between adjacent fasteners. Provide the required bolt load and joint dimensions when selecting the tooling, and confirm the tensioning arrangement and pump pressure with the model data.
