Hydraulic bolt tensioning service involves using hydraulic tools and equipment to accurately apply tension to bolts in various applications, ensuring proper and uniform clamping force. This service is commonly utilized in industries such as construction, oil and gas, power generation, and heavy machinery.
Unlike conventional methods, it does not use torque and does not require any forceful turning of the nut or bolt, like impact wrenches, flogging spanners or hydraulic torque wrenches. All of these methods have one common enemy: FRICTION. Overcoming thread friction and friction between the nut and the washer uses up over 80% of the torque energy applied to the nut or bolt, leaving less than 20% of the energy to produce useful tension in the shank of the bolt. Variations in this friction loss, from bolt to bolt causes non uniform tension in bolts that have been tightened to the same torque or impact wrench setting.
Hydraulic bolt tensioning services offer several advantages over traditional bolting methods, including increased accuracy, reduced risk of bolt failure, improved safety, ease and speed of operation, which can be simultaneous, give downtime reductions, reduce costs and increase productivity for tightening critical bolted joints.. By employing hydraulic tools and techniques, precise and uniform tension can be applied to bolts, contributing to the integrity and reliability of critical infrastructure and equipment.
