Conventional NDT Services

"Conventional NDT Services" typically refers to traditional Non-Destructive Testing (NDT) methods used to evaluate the integrity and properties of a material, component, or system without causing damage. These are widely used in industries like oil & gas, aerospace, construction, and manufacturing.

Here are the main types of Conventional NDT Services:

• 1. Radiographic Testing (RT):
  • Description: X-rays or gamma rays are used to examine the internal structure.
  • Used For: Detecting internal cracks, voids, or inclusions in welds or castings.

• 2. Ultrasonic Testing (UT):
  • Description: Uses high-frequency sound waves to detect internal flaws or thickness.
  • Used For: Weld inspection, corrosion mapping, material thickness measurement.

• 3. Magnetic Particle Testing (MPT):
  • Description: Magnetic fields and iron particles are used to find surface and near-surface discontinuities in ferromagnetic materials.
  • Used For: Surface crack detection in welds, fasteners, and structural steel.

• 4. Liquid Penetrant Testing (PT):
  • Description: Dye or fluorescent penetrant is applied to a surface, then drawn out of defects by capillary action.
  • Used For: Surface-breaking defects on non-porous materials, both ferrous and non-ferrous.

• 5. Visual Testing (VT):
  • Description: Inspection using the naked eye or tools like magnifying glasses, borescopes, or video scopes.
  • Used For: Surface defects like cracks, corrosion, misalignments, weld quality.

• 6. Eddy Current Testing:
  • Description: Uses electromagnetic induction to detect surface and near-surface flaws.
  • Used For: Cracks, material thickness, conductivity, and heat treatment verification.
