IKM Testing provides improved methods for the tightening of bolted flange connections. These methods of tightening are essential for systems that are exposed to severe operating conditions or where a correct stress distribution in the bolted joint is required. These methods of controlled tightening are commonly referred to as Bolt Torquing and Bolt Tensioning. They are two totally different methods of bolt tightening, one is a gradual method of induced load and the other instantaneous. Torque tightening involves the rotation of the nut on its bearing surface and is highly dependant on correct and adequate lubrication, whilst tensioning induces the load axially, by stretching the bolt within the elastic limits of its material to supply the desired bolt load.

IKM Testing has extensive experience in the execution of controlled tightening to any bolted joint and the provision of mechanical joint integrity. Our skilled technicians will provide a leak free joint on process systemconnections and offer the added assurance of a leak free start up.
