abstract

This paper describes the design and development of a new Cylinder Bolting System to replace the Main Joint Hardware for both Combustion (and Steam) Turbine applications. The new bolts are designed to be hydraulically tensioned to the specified preloed and utilize ultrasonic verification of elongation. The new Bolting System uses a reduced number of components in each assembly and the individual components themselves are of a simplified design. The new hardware can be applied to new equipment without modification and retrofitted to customer owned equipment as a direct replacement for existing joint hardware. The prototype, production and field testing of this hardware, the installation tooling and ultrasonic elongation measuring equipment is described. This testing has shown significant savings in assembly and disassembly cycle times even after prolonged exposure to turbine operating temperatures in a corrosive environment. The new design of bolting is now standard equipment for the CW251B11/B12 Combustion Turbine manufactured by Westinghouse P.G.B.U.
