NDT (Non-destructive Testing)

Non-destructive testing (NDT) is a wide group of analysis techniques used in science and technology industry to evaluate the properties of a material, component or system without causing damage. NDT or NDE can be used to find size and locate surface and subsurface flaws and defects. Abu Zaeem LLC provides following services:

Magnetic Particle Inspection:

The experienced, skilled magnetic particle testing (Abu Zaeem LLC) technicians will detect surface and sub-surface defects in ferromagnetic metals, such as iron, cobalt, nickel and some alloys.

Dye Penetrant Testing

DPT is an NDT method of revealing discontinuities that are open to the surfaces of solid and essentially nonporous materials. Liquid penetrant testing is probably the most widely used NDT method.

Video Scope

An industrial videoscope is a flexible inspection tool used to remotely inspect areas that are not otherwise visible. An industrial videoscope is typically used for visual or non-destructive testing.

Ultrasonic Testing (UT)

Ultrasonic testing is an advance technique that offers improved Probability of Detection of the smallest defects, and can provide you with accurate reporting of the size and location of sub-surface irregularities and flaws in material or products.

Digital Radiography (DR)

Digital radiography is becoming more widely used for detecting defects, cracks, corrosion, erosion and loss of wall thickness. In this technique images are captured using either flat panel detectors or phosphor-coated imaging plates.

Positive Material Identification (PMI):

PMI is a used to recognize the metallic composition of metal using instruments like x-ray fluorescence (XRF) without doing any alterations the substance being tested. This information is essential to ensure material meets specifications for best performance.

Phased Array (PA):

Phased Array (PA) provides sharper detection capability for off-angle cracks, and is capable of displaying multiple presentations simultaneously. It is an advanced pulse-echo technique that utilizes multiple miniaturized transducers and time-delays to shape the ultrasonic sound beam to a desired angle and focus.

Time of Flight Diffraction (TFD):

With TFD, a single line scan of a pair of angle compression wave probes held at a fixed separation can provide full volumetric coverage of both weld and heat affected zone. One of the important advantages of using TFD for weld inspection is the absence of radiation.
