We’ve seen erosion on several valve stems in our steam turbine. What are the best strategies for preventing this issue and repairing damaged components?
Switch to hardfaced stems. They’re more resistant to wear and can handle high velocities better.
Inspect for steam impurities. Particulate matter is often the root cause of erosion on valve stems.
Ensure proper alignment of valves. Misaligned stems can exacerbate wear and lead to erosion.
