Rapid simultaneous bolt tensioning
Atlas Copco Bolt Tightening Solutions guide on detachable bolt tensioners.
Applies a predictable and accurate pre-load to all studs simultaneously, thus eliminating the problems normally associated with conventional torque tightening techniques.
The segmented Multi-Stud bolt tensioning system is a detachable system designed to simultaneously tension all studs on system closures such as steam generator primary and secondary manways, hand wheel and valve covers. This state of the art system applies a predictable and accurate pre-load to all studs simultaneously, thus eliminating the problems normally associated with conventional torque tightening techniques such as uneven gasket pre-loads resulting in closure leakage, galling, broken fasteners, etc. All frictional factors connected with conventional bolt tightening methods are alleviated since MST systems apply a direct axial force to the bolts which generate a bolt elongation. Everything about the design of a Tentec MST is included to allow for extremely rapid and simple bolt tensioning.
