Hydraulic Bolt Tensioning

Atlas Copco Hydraulic Bolt Tensioning systems apply precise, controlled axial load to fasteners by hydraulically stretching the bolt and then advancing the nut to lock the achieved load, eliminating the friction variables that make torque-controlled tightening inaccurate in critical bolted joints. Used extensively in oil and gas, power generation, petrochemical, and heavy engineering where flange joint integrity is safety-critical, hydraulic bolt tensioning provides repeatable, verifiable clamp load results that torque tools cannot match on large-diameter or high-preload fasteners.
