The Advanced NDT Department of QIS Company continues to reinforce its position as a leading provider of high-technology inspection solutions in Vietnam. Recently, our team successfully applied Pulsed Eddy Current (PEC) technology in Corrosion Under Insulation (CUI) testing for multiple industrial facilities in the Northern region.

With the growing demand for non-intrusive and highly accurate inspection methods, PEC has become one of the most effective techniques for detecting corrosion through insulation, coatings, fireproofing, and cladding — without the need for surface preparation or insulation removal. This not only reduces shutdown time but also minimizes maintenance costs and operational risks for factories.

During recent service campaigns, QIS’s certified NDT specialists deployed state-of-the-art PEC equipment to inspect pipelines, pressure vessels, and critical process lines affected by CUI. The inspection provided reliable data on remaining wall thickness, corrosion mapping, and the overall structural condition of the assets. These results enabled plant owners to make timely and informed decisions regarding repair, replacement, or continued operation.

As part of our commitment to delivering world-class inspection solutions, QIS’s Advanced NDT Department continuously updates international standards, invests in advanced technologies, and enhances personnel competency through global training and certification programs. Our application of PEC technology once again reaffirms QIS’s dedication to supporting factories across Vietnam with safe, efficient, and innovative inspection services.

If you need assistance with CUI assessment, PEC inspection, or any advanced NDT technology, QIS is always ready to support your plant with professional and comprehensive solutions.
