What is Non-Destructive Testing (NDT)?

NDT refers to inspection techniques that evaluate the properties, integrity, and performance of materials, components, or systems without causing damage. These methods are essential for quality control, safety assurance, and preventive maintenance.

Which NDT method should I use for weld inspection?

For surface-breaking defects, Magnetic Particle Inspection (MPI) or Penetrant Testing (PT) are effective. For subsurface flaws, Ultrasonic Testing (UT) is preferred. Radiographic Testing (RT) provides a permanent record and is excellent for volumetric inspection.

Do you provide calibration services?

Yes, we offer comprehensive calibration and certification services for all our NDT equipment to ensure measurement accuracy and compliance with international standards.

Can your equipment be used in hazardous environments?

Many of our products are available in intrinsically safe or explosion-proof versions suitable for use in hazardous locations such as oil refineries, chemical plants, and offshore platforms.

Do you offer training for your NDT equipment?

Yes, we provide on-site and remote training programs for operators and technicians to ensure proper use, interpretation, and maintenance of our equipment.
