Non-Destructive Testing (NDT) Equipment and Automation Systems

Non-Destructive Testing (NDT) Equipment and Automation Systems
Non-Destructive Testing (NDT) Equipment and Automation Systems
Non-Destructive Testing (NDT) is a critical quality control methodology applied to detect surface, sub-surface, and volumetric defects without damaging the integrity, structure, or geometry of industrial materials, forged/cast components, critical steel wire ropes, rail tracks, and weldments. Complying with stringent aerospace, defense, automotive, railway, and heavy industry standards (such as Nadcap, ASTM, API, ISO) is only possible by selecting high-performance NDT equipment and inline automation lines tailored to the specific component geometry.
As NEXSEN, we design, manufacture, and distribute turnkey non-destructive testing systems and engineering solutions that are 100% compatible with the production cycle times and accreditation requirements of modern industrial facilities.

Featured Engineering Solutions & Focused NDT Product Lines

Our flagship ndt devices and automated systems minimize human error, optimize cycle times, and capture the most precise discontinuities in your manufacturing lines:

1. Automated Magnetic Particle Inspection (MPI) & Integrated Demagnetization Lines

We deliver world-class, turnkey projects for surface and sub-surface crack detection in ferromagnetic components.
  • Automated Magnetic Particle Inspection Systems (MPI Lines): Fully automated mass-production lines featuring robotic handling integration, synchronized conveyors, pass-through layouts, and multi-directional magnetization.
  • Magnetic Particle Inspection Systems: Rugged manual and semi-automatic industrial MPI test benches for flexible batch testing.
  • Portable MPI Power Units: Heavy-duty mobile high-current generators engineered for on-site (in-situ) testing of massive structures in shipyards and construction zones.

    • Integrated Industrial Demagnetization: Tunnel, conveyorized, and standalone demagnetizer units designed to fully eliminate and neutralize residual magnetism post-MPI or machining stages. (NEXSEN is the official representative of the global pioneer DeltaFlux).

2. Liquid Penetrant Testing (PT) Lines, Benches & Booths

We reveal surface discontinuities, pores, and micro-cracks with supreme visibility on non-magnetic materials (aluminum, titanium, stainless steel, aerospace alloys, ceramics, etc.).

Liquid Penetrant Testing Line: Modular or fully automated lines combining penetrant application, pre-wash, emulsifier, post-wash, drying ovens, and storm (developer) powder stations into a seamless continuous workflow.

  • Liquid Penetrant Testing Benches: Ergonomic, stainless-steel manual or semi-automatic penetrant workstations optimized for laboratories or mid-scale inspection facilities.

    • Penetrant Inspection Booth:Custom darkrooms enclosed with heavy-duty curtains, automated ventilation systems, and integrated high-intensity overhead UV LED lights designed for supreme operator comfort during fluorescent evaluation.

Online Eddy Current (ET) Systems: High-sensitivity inline systems that detect longitudinal and transverse surface cracks within milliseconds on welded/seamless tubes and drawing lines, utilizing automated sorting gates to reject defective material instantly.

4. Advanced Eddy Current Testing (ET) Devices & Material Sorting

  • Eddy Current Material Sorting: Customized automated sorting stations leveraging eddy current frequencies for non-contact, high-speed verification of heat treatment structures, hardness variations, decarburization depths, and alloy/material mix-ups.

Ultrasonic Flaw Detectors & Thickness Gauges: Conventional volumetric flaw detectors and ultra-precise corrosion/wall thickness measurement gauges.

6. Magnetic Rope Testing (MRT) Instruments

Electromagnetic Steel Wire Rope Testing Devices: Portable and industrial MRT instruments designed to test critical steel wire ropes used in mining shafts, cable cars, elevator systems, cranes, shipyards, and suspension bridges. It accurately reports localized faults (LF) like broken wires, wear, and loss of metallic area (LMA) due to corrosion without damaging the rope.

7. Remote Visual Inspection (RVI) – Industrial Videoscopes

Industrial Videoscope and Industrial Boroscope: State-of-the-art optical instruments featuring multi-way articulating probes, powerful high-density LED illumination, and crystal-clear HD displays for the intricate internal visual inspection (VT) of turbine blades, engine blocks, cast cavities, and long pipelines.

9. Industrial Radiography (X-Ray) Systems

  • Conventional & Digital Radiography (RT): Industrial X-Ray tube generators, Computed Radiography (CR) scanner plates, and Digital Radiography (DR) flat panel detectors engineered for non-destructive volumetric evaluation of castings and critical weld structures.

Technical Engineering Criteria for NDT System Selection

Investing in the correct ndt systems reduces scrap costs while exponentially raising operational safety. Our expert engineering team evaluates the following variables during layout planning:
  1. Material Group and Flaw Orientation: Whether the target material is ferromagnetic or not, and whether the defect is strictly on the surface (MPI, PT, Eddy Current Array) or deep within the internal volume (Phased Array UT, Radiography) dictates the optimal technology.
  2. Line Integration & Velocity: Continuous production mills require high-speed Online UT and Online Eddy Current networks, whereas batch-processed components or heavy transportation infrastructure call for robotic Automated MPI, Automated Penetrant Lines, or Mobile Rail Inspection Units.
  3. Global Audit Compliance: For aerospace (Nadcap), military, or railway sectors, international code compliance requirements (ASTM, EN ISO, ASNT) must be fully integrated into both software algorithms and hardware calibration baselines.
