Large Steam Turbine Crossover

Built for MHI Customer in Indonesia

The steam turbine is the very heart of any base load power generating facility. These turbines generally have a high pressure turbine and a low pressure turbine on the same shaft. Many times, there is also an intermediate pressure turbine. A crossover expansion joint carries the steam between the turbine sets. The crossover is every bit as critical as the turbine because failure or leakage is cause for immediate shutdown of the power plant.

The crossover must be made to very precise tolerances to insure proper fit up in the field. The MHI crossovers were built with proven methods to insure such fit up in the field. The Senior Flexonics Pathway design also incorporated a reinforced ply testable bellows leak detection system. The ply testable system provides the opportunity to sense a leak in a bellows and continue safe operation without loss of steam even if a leak is detected.
