Magnetic Particle Inspection

Introduction

Libellum delivers professional Magnetic Particle Inspection (MPI) services to support quality assurance, weld integrity, and compliance in fabrication, manufacturing, and construction projects. MPI is a fast and effective non-destructive testing method that identifies surface and near-surface defects in ferromagnetic materials, providing early detection of issues that could impact structural integrity or project performance.

Our certified inspectors combine technical expertise with advanced MPI techniques to deliver reliable results and comprehensive reporting.

Our MPI Services

Surface & Near-Surface Defect Detection

We detect cracks, porosity, laps, seams, and other surface or near-surface discontinuities in ferromagnetic materials using magnetic particle inspection, ensuring the integrity of welds and critical components.

Integration with Welding & Fabrication Quality Programs

Our MPI services complement CSWIP weld inspections, Responsible Welding Coordinator (RWC) oversight, and general weld quality programs, providing an additional layer of assurance and compliance.

On-Site and In-House Inspection

Libellum provides flexible MPI services, whether on-site at your facility or in-house at our controlled inspection environments. This allows for minimal disruption to production while ensuring accurate and reliable inspection results.
