Epri condenser tube steam erosion6/2/2023 ![]() ![]() As discussed in “Optimizing Condenser Tube Selection,” earlier in this issue, a plant engineer has several materials from which to choose when specifying a replacement set of condenser tubes. The steam surface condenser is the largest heat exchanger in a power plant, and the quality of the tubing within the condenser is critical for reliable plant operations. When it’s time to select new condenser tube material, you’ll need to consider the projected operating environment and failure mechanisms that material will be subjected to. The most important tube failure mechanisms typically result from different forms of corrosion and erosion. The operating environment within a condenser is extremely harsh, and in spite of the designer’s best intentions, sometimes tubes made of the best materials fail.
