Nozzle segments

Nozzle segments are the part of the turbine for directing the flow of steam with a specific, accurately calculated flow and direction for the medium. 

Originally, manufacturing prior to 1997 was highly laborious and challenging. Through innovation, we created a monolithic nozzle segment that is inserted directly into the turbine as a single unit.
