On a typical HP turbine, the loosening or tightening of all the bolts can normally be completed within a ten hour shift, reducing the outage schedule by days.

This process has far more benefits than economics, the issue of safety is a major concern in all industry and particularly associated with this task during an outage. With cartridge heaters, 240 volts is the industry standard and gas heating has it's own inherent safety concerns. The Mannings USA (UK) PLC induction heating system expands the bolts so thoroughly that the need for slugging spanners and twenty pound hammers is considerably reduced, the nuts can usually be removed with simple hand tools.
