Wether in construction, mechanics, oil & gas and power-plants: regular inspection and maintenance of bolted joints is crucial for various industries in order to avoid costly system failures and to ensure operability.
Regular checks can also detect any inadmissible changes compared to the approved version.
The knowledge of the real preload force-time behavior of planned preloaded bolting-connections enables the design and construction of low-maintenance /-free bolt connections for the industry.
Benefits are zero leacking-flanges, the reduction of costs through longer inspection intervals, costly ad hoc checks or prevention of the replacement of complete bolt joints. Overall the work and company safety as well as the operating costs can be significantly optimized
What will participants learn from this prensetation?
Example of a refinery in Europe
+ Flange-Concept to achieve sustainably tight flanges
+ Flange marking - Precise definition of tightening and loosening
?+ Tightening without reaction arm or back-up wrench with repeatable assembly
preload with standard torque wrenches in the range of 60 to 190,000 Nm also in explosion risk zones and subsea
+ Why can bolt-joints fail? - Technology as a factor
+ Why can bolted joints fail? - HUMAN element
+ Evaluation with LDAR method = leak detection and repair
+ Standards and Guidelines
+ hydraulic Torque-Wrench-Systems
+ Lithium-Series II (LST) - The digital, battery-operated torque / angle torque wrenches
+ Increasing saftey by using handfree bolting-systems
+ many examples from the practice
