After the decade, NDT Overseas has systematically and progressively established its conventional NDT services by global leading engineering equipment manufacturers and Oil & Gas industrial platforms.
Ultrasonic testing is one of the major Sub surface ndt method. Ultrasound beams (Straight/ Angle) are passing through materials, part and assembly, UT shall be performed on principle basis of reflection through transmission. It contains variant technique/s in terms of applications.
Magnetic Particle Testing is Surface and nearby surface ndt method. it's inspected on ferrous material either a material containing magnetization properties. The technique/s is chosen in terms of current (AC/DC) availability with equipments and applications.
Liquid Penetrant Testing is Surface ndt method. Itâ€™s generally used for all materials and applications followed by below techniques.
Visual Testing is major Surface ndt method. Visualization is main tool for result (Accept/ Reject) analysis. VT is an common practice followed and performed in any ndt method before & after.
Radiography testing is reliable Sub surface ndt method. In RT inspections test parts is placed between radioactive material (source) and films. Exposure informationâ€™s (principle basis of absorption through transmission) can be recorded on films, it shall be viewable format. Also make results justifications easier. The exposure involved in radiographic testing, more care shall be required to handling radioactive material as per local law and rules. Radiation Protection is the tool to ensure our environmental safety.
