The problem with bolted connections has always been that there is no way to be sure that an assembly has achieved or kept the required bolt load. The most common reason for gasket joints to start leaking is unequal and insufficient bolt load. For instance, during assembly, gaskets are overloaded to compensate for later relaxation. This especially happens with hydraulic tensioners. But it remains unclear what the relaxation over time will be. Other occurring problems might be bolts breaking due to fatigue issues, bolts coming loose or doing unnecessary maintenance to check up on the bolts. Not knowing the right tool setting or bolt load during assembly or while the bolts are mounted can cause serious problems. Maintenance costs will rise and result in expensive check-ups and re-tightening procedures. Right now, these procedures are very common for high loaded bolted constructions such as cranes and wind turbines. The challenge BoltSafe took up is to prevent these check-ups and make sure that no re-tightening is necessary.
