“At INTEGRA Technologies everything we do ensures the safety and reliability of the energy infrastructure that serves society.
Bolted-connections remain as one of the critical elements that effect plant integrity and reliability.
Without the use of advanced tool technology, bolted-connections pose a significant threat of hand injuries and can drastically shift your critical-path-schedule due to disassembly-speed and reliability concerns.
Hydraulic Bolt Tensioning technology provides the highest level of accuracy, productivity, and safety on critical joints across the energy industry.
Assembly of Hydraulic Bolt Tensioners is started by sliding the hydraulic load cell over the stud bolt until it comes in contact with the flange. The Bolt Tensioner’s puller is then threaded down into each load-cell until securely in contact with the cylinder piston.
Each tensioner is then connected together via hydraulic hoses. You then apply the specified hydraulic pressure, which actuates the hydraulic load-cells and simultaneously places load across the flange by all the interconnected Bolt Tensioners.
Using a tommy-bar you then turn the locking collar on each Bolt Tensioner to place the nut firmly onto the joint surface. Tool pressure is then released and the bolt tensioning procedure is complete!
But the question remains, why do you want to utilize Hydraulic Bolt Tensioning?
Simply put, it helps ensure your operations are leak free saving you time and money but most importantly keeping your workforce safe!
In order to deliver a leak-free bolted-assembly you must apply the correct amount of compressive-load to the sealing-surface or gasket. Hydraulic Bolt Tensioning is the superior method to deliver this load because it’s accurate, fast and safe!
It’s accurate because tensioning provides the reliability required by delivering precise bolt-loads to the joints.
It’s fast because in contrast to bolt torqueing, Bolt Tensioning can eliminate crosstalk and deliver simultaneous bolt-load and gasket-compression across the entire joint.
Tensioning also drastically reduces the likelihood to gall threaded fasteners, helping you avoid potential delays and rework.
It’s safe because tensioners are a hands-free technology that minimizes work-related accidents.
Since 1986 INTEGRA Technologies has been recognized as the leading expert in Bolted Joint Integrity.
We have pioneered the use of Hydraulic Bolt Tensioning services and rentals in the oil and gas and power generation market places across North America and we continue to be at the forefront of the technology today
