Advance Non-Destructive Testing
is a development from conventional non-destructive testing using advancement of computer and data processing technologies which make the testing safer, faster and more accurate. At present the company provides the following services:
1. Acoustic Emission Test (AE)
used for finding expansion of defects, leakages or rusting of equipment such as aboveground storage tank, pressure vessel. This AE test is a highly advanced technology which enables test to be carried out during a manufacturing process so that there is no need for a suspension of the manufacturing process, reducing testing steps and pollution from sediment inside the tank or pressure vessels.
2. Remote Field Eddy Current (REFT)
is a test for defects on stainless tubes and materials other than iron-carbon of heat exchangers and condensers used in petroleum industry.
3. Magnetic Flux Leakage (MFL)
is a magnetic field test to find defects on iron-carbon tubes with fins of heat exchangers and condensers used in petroleum industry.
4. Internal Rotating Immersion System (IRIS)
is a test using high-frequency waves to find defects on metal tubes of heat exchangers and condensers used in petroleum industry.
6. Phase Array Ultrasonic Test (PAUT)
uses high-frequency ultrasonic sound to detect defects in metal by combining many elements into one probe which allows the test to cover wider area, be carried out more quickly and give more accurate results than normal ultrasonic methods.
7. Time of Flight Diffraction Ultrasonic Test (TOFD)
uses high-frequency ultrasonic sound to detect defects in metal by using sound wave-diffraction technology which is very accurate in assessing size and location of a defect.
