Non-Destructive Testing
Non-Destructive Testing (NDT) – Ensure Safety Without Damage
Hidden defects in your equipment, containers, or lifting materials can lead to safety risks, costly downtime, and compliance failures. Replacing parts too early is wasteful, while missing a flaw can result in accidents or rejected certifications.
With Non-Destructive Testing (NDT), HTT detects flaws without damaging your materials—giving you certainty about quality, safety, and compliance.
Our NDT Methods:
🔹Visual Testing (VT)
The most widely used and cost-effective inspection method. Our experts use the naked eye or tools like magnifiers, cameras, or endoscopes to identify visible cracks, surface imperfections, or weld defects.
Simple and inexpensive
Applicable to all materials with visible surfaces
Often the first step in the inspection process
(Limitations: only surface-level, dependent on visibility)
🔹 Magnetic Testing (MT)
Ideal for ferromagnetic materials, this method quickly detects surface and near-surface cracks using a magnetic field and contrast agents.
Fast inspection of large areas
Immediate detection of defects on and below the surface
🔹 Penetrant Testing (PT)
Perfect for identifying even the smallest surface-breaking cracks. A colored penetrant highlights defects, and a developer makes them clearly visible.
Detects minor surface defects
Covers large surfaces efficiently
Clear, immediate results
(Surfaces must be coating-free — we can handle this with our mobile burner.)
🔹 Eddy Current Testing (ET)
The best solution when coating removal is not possible. Using electromagnetic fields, we detect defects on and just below the surface of conductive materials.
Works without removing coatings
Detects cracks and irregularities just under the surface
Immediate, reliable results
No chemicals or fluids required
Clear Proof & Reporting
After every testing, you receive a detailed proof of examination:
✅ Approval report if results meet acceptance criteria
❌ Rejection report with clear advice if issues are found
This way, you always know exactly where you stand—and can take corrective action before small issues turn into big risks.
