Dye Penetrant Inspection

Introduction

Libellum delivers professional Dye Penetrant Inspection (DPI/PT) services to ensure surface defect detection, weld integrity, and component quality in fabrication, manufacturing, and construction projects. DPI/PT is a proven non-destructive testing method that reveals surface-breaking discontinuities, allowing early detection and remediation before defects affect performance or compliance.

Our certified inspectors use the latest techniques to provide accurate results and comprehensive reporting, supporting quality assurance and certification requirements.

Our DPI/PT Services

Surface Defect Detection

We detect cracks, porosity, laps, and other surface discontinuities in welds, castings, and components, helping to maintain structural integrity and reduce the risk of failures.

Integration with Quality & Welding Programs

DPI/PT services complement CSWIP weld inspections, Responsible Welding Coordinator (RWC) oversight, and overall weld quality programs, providing an additional layer of assurance for your project.
