Save time
They greatly reduce to time it takes to disassemble and reassemble the turbine couplings due to their ease of use. To install them you slide them in the hole in a clearance condition, expand the sleeve and tension the nuts. To remove them the process is reversed, de-tension the nuts and release the sleeves and the bolts slide out of the hole in a clearance condition. The time required is roughly 10 minutes per bolt, this now gives you a known timeframe for your schedule. The work is carried out with a hydraulic pump and small tooling, the coupling can be assembled or disassembled without wearing out half the crew.
