Coating Thickness Testing (DFT Measurement) Services
Non-destructive Coating Thickness Testing (DFT) on ferrous and non-ferrous substrates for protective paint, epoxy, powder coating, and galvanizing. Testing is performed by appropriately qualified and certified NDT personnel in accordance with applicable codes, standards, specifications, and approved procedures.
Principle & Testing Methodology
Coating Thickness Testing uses magnetic induction (for non-magnetic coatings on ferrous substrates) and eddy current principles (for non-conductive coatings on non-ferrous substrates). Calibrated digital gauges measure dry film thickness without damaging the protective coating system.
Defects & Discontinuities Detected
- Insufficient coating thickness leading to premature corrosion
- Excessive coating thickness resulting in mud-cracking and adhesion failure
- Non-uniform application across weld seams, edges, and corners
- Inadequate galvanizing thickness on structural steel members
Typical Industrial Applications & Components
- Structural steel fabrication for PEB buildings and bridges
- Internal and external pipeline anti-corrosion coating (3LPE / FBE)
- Marine and offshore protective painting systems
- Automotive chassis and body panel electro-deposition coating
Applicable Materials
Paint, epoxy, polyurethane, powder coating, rubber lining, and hot-dip galvanizing over steel, iron, aluminum, and brass.
