Corrosion Engineering

Our Corrosion Engineering Testing Services

Our engineers and technicians utilize their academic training, field experience, and advanced analysis tools to identify and help control modes of corrosion and environmental degradation of materials that can lead to component or system-wide failures with our corrosion engineering services.

We maintain the capability to conduct standardized materials and corrosion tests at our spacious materials laboratory located in Houston, TX.  However, our passion is designing and conducting customized corrosion, cracking, and materials qualification tests in both sweet (CO2) and sour (H2S) environments.  Our focus is always to understand and then to accurately duplicate the loading, environmental, and other conditions that client materials face in real life, so that test results can be applied to solving real world problems.

For instance, our subject matter experts have improved and refined the jet impingement technique for flow corrosion testing to allow both in depth scientific investigations and routine tests using re-circulating, batch or once-through flow, including gas-in-liquid or liquid-in-gas systems. In addition, we have developed innovative techniques for: slug flow correlation, corrosion inhibitor evaluation in low and high shear stress conditions, batch inhibitor testing, and determination of corrosion inhibitor concentrations and inhibitor persistency.
