Steam Turbine Seals: An Advantage in Today’s Challenging Environment

The steam turbine rotor is a critical component and protecting it is key to a successful operation. Rubs during startup between labyrinth shaft seals and the rotor can present a number of issues.

New seals typically rub during the first few starts, negating valuable maintenance dollars invested to restore seal clearances. Secondly, shaft seal rubs can cause a bowed rotor, which damages the tight clearance of blade tip seals where in severe cases, the rotor will suffer from permanent impairment.

In conclusion, risks can quickly turn into costly maintenance dollars as well as the financial impact associated with the decrease in turbine performance.


Why SMART Seals™

Meanwhile, our SMART Seals™ can be applied to any steam turbine in any application or service. Each SMART Seals™ package is customized by engineers, addressing the customer’s specific operational goals.

The upgrade package is built from a combination of features to enhance turbine reliability by avoiding rubs, maintaining tight clearances to improve performance, and lower operating costs.
