inspection technicians are professionally trained and certified by a third party to ensure that you are receiving accurate and useful feedback. The trained eye of an experienced inspector can prevent an accident from occurring and save money on repairs that may not be critical. Gulf America's Non-Destructive Testing
is the practice of using written standards to inspect welds, castings, forged metals and vessels to see if there are any indications of porosity, fatigue, cracks or other anomalies. These inspections include:
- Magnetic Particle Testing
- Dye Penetrant Testing
- Visual Testing
- Ultrasonic Testing & Inspection
Detects discontinuities in ferrous metals by applying a magnetic field to the part. Then a wet or dry magnetic flux is applied to the part. The flux is attracted to discontinuities and begins to build up at the discontinuity which is known as an indication. The indication can then be evaluated to determine what it is, what may have caused it, and what action should be taken, if any.
Also called liquid penetrant inspection (LPI) or penetrant testing (PT), is used to locate surface-breaking defects in aluminum and stainless steel. The penetrant may be applied to all non-ferrous materials and ferrous materials, although for ferrous components magnetic-particle inspection is often used instead for its subsurface detection capability. LPI is used to detect casting, forging and welding surface defects such as hairline cracks, surface porosity, leaks in new products, and fatigue cracks on in-service components.
Often performed on steel and other metals and alloys. It uses very short ultrasonic pulse-waves with center frequencies ranging from 0.1-15 MHz and occasionally up to 50 MHz are launched into materials to detect internal flaws or to characterize materials. A common example is ultrasonic thickness measurement, which tests the thickness of the test object, for example, to monitor pipework corrosion.
