Failure Analysis and Physicochemical Testing
Failure analysis involves systematically examining failure phenomena—such as corrosion and component fractures—in equipment and materials through professional physicochemical testing methods. It precisely identifies the root causes of failures—including material defects, design flaws, improper operation, and environmental factors—and swiftly develops corrective measures to prevent recurrence of the problem.
Our company maintains close collaboration with the Institute of Metal Research, Chinese Academy of Sciences, and continuously provides failure analysis and physicochemical testing services. We currently have a professional team composed of PhDs, masters, and senior engineers, equipped with specialized analytical instruments such as Zeiss metallographic microscopes, Oxford spectrometers, Hitachi scanning electron microscopes, and X-ray diffractometers. As of 2025, we have cumulatively provided over 1,000 failure analysis and individual physicochemical testing projects to various petrochemical and oilfield enterprises.
