APTECH has performed laboratory failure analysis on thousands of power plant components from hundreds of power plants. Some of the failure modes and components we’ve investigated are listed below. APTECH can apply its facilities and expertise to quickly determine the root cause of your equipment problems, and assess how these problems can be corrected. We specialize in solutions to your problems.
