Leak Detection in
Steam Turbine

Steam turbines are challenging environments for leak detection due to high temperatures and the fact that the test media is water vapor, which can easily cause significant damage to pumps and other components
The Agilent Harsh Environment (HE) Probe can be inserted directly into the high temperature vapor stream to enable helium mass spectrometer leak detection. Combined with an Agilent HLD leak detector, the direct measurement technique enabled by the probe gives more accurate, repeatable results while also preventing instrument damage or degradation. Equipment damage or failure due to corrosion or water in the leak detector or roughing pump is eliminated.
The HE probe does not require dryers, chillers, a secondary vacuum pump, or throttling valves in order to sample in wet, high-temperature environments. It is constructed of 316L stainless steel with a composite permeable membrane at its tip, and is able to withstand water and amines (corrosive ammonia derivatives), and operate at temperatures up to 95 °C (200 °F).
