The NDT (Non-destructive testing) is a widely used inspection solution for numerous types of industries in the plant operations, manufacturing, construction and other engineering sectors. Which is a branch of engineering concerned with methods of detecting and evaluating flaws in the materials. The NDT produces no damaging effects on the material or structure under test and assists with guaranteeing safe operation, quality control, and assessing plant life.

Defects or Flaws may present as cracks or inclusions in welds and castings or variations in structural properties—all of which have the potential to lead to loss of strength or failure in service. There are many different types of Non-Destructive Testing methods available, each of which has both advantages and disadvantages.

Conventional Non-Destructive Testing Methods

ET - Electromagnetic Testing

The ET – Electromagnetic Testing include the following Services;

  • Crane Inspection
  • Drilling Equipment Inspection

The Electromagnetic Testing (ET) Detects surface and near-surface cracks without removal of paint coatings, of electrically conducting material.

Electromagnetic testing, also known as eddy-current testing, is used to detect small, surface breaking defects through paint and some coatings in electrically conducting materials. Applications for ET include crack detection, metal sorting, and inspection of tube, bar, and welds.

IPES Inspection Service Division makes sure competent inspectors are assigned and along with right equipment for the task to be undertaken. Our strategy of assigning Rope Access Capable UT Inspectors for the task saves execution time of the project.

MT - Magnetic Particle Testing

The MT – Magnetic Particle Testing include the following Services;

  • Weld Inspection
  • Rack Teeth Integrity Survey
  • Drilling Equipment Integrity Survey

The NDT Method of MT detects the surface and near-surface cracks in ferrous material. Surface and subsurface discontinuities in ferrous materials can lead to machinery and production shutdowns but are often not easy to spot in time.

MT requires the application of a magnetic field using a permanent magnet or electromagnet around the inspection. Following magnetization, the inspection area is covered with a ferrous oxide particle detection medium, that is either dry or suspended in a liquid. Flaws distort the magnetic field, causing local magnetic flux leakage that attracts the detection medium and indicating the presence of a flaw.

The Liquid Penetrant Testing detects the surface-breaking cracks, cold laps, porosity and other defects. The Surface-breaking defects in machinery can mean a shutdown in production and a loss of revenue. IPES Inspection Services Division offer PT inspection method to locate surface-breaking defects in all nonporous materials – including metals, plastics, and ceramics. It can be applied to all non-ferrous and ferrous materials.

Ultrasonic Testing (UT) Evaluates external flaws, wall thickness, and detection of internal flaws. This NDT Method uses high-frequency sound waves to measure material thickness and detect surface and subsurface flaws. UT is often used to locate manufacturing defects in welds and castings, complete corrosion and erosion monitoring, and support large-scale corrosion mapping.

UT is a portable and quantitative inspection method offering flexible inspection variations including Straight Beam and Angle Beam. Specialist NDT variation of UT are Phased Array and Time of Flight Diffraction (TOFD). The success of UT requires a clean surface so that couplant can be applied between the probe and the surface to enable the required sound transmission.

Visual inspection of plant assets to identify the physical damages, degree of corrosion or rusting, and surface open wide cracks are examples of anomalies that are commonly identified during visual inspection.

Critical to successful application of this method are factors including the calibration and quality of the image-capturing method, the inspector’s competency and especially the knowledge of the assets and their operating conditions, anomaly identification criteria, understanding of the defects, and proper documentation.

AUT – Automated Ultrasonic Testing

The Automated Ultrasonic testing – AUT can be deployed to the following Services;

  • Vessels/Tanks: Large Structure Inspection

MFL – Magnetic Flux Leakage Inspection

Magnetic flux leakage (MFL) is an electromagnetic non-destructive testing technique used to detect corrosion and pitting

MFL uses a powerful magnet to magnetize the conductive material under test (usually steel). Where there are defects — corrosion or material loss — the magnetic field “leaks” from the steel.

MFL probes incorporate a magnetic detector placed between the poles of the magnet where it can detect the leakage field. During inspection, a magnetic circuit of sorts forms between the part and the probe. The magnetic field induced in the part saturates it until it can no longer hold any more flux. The flux overflows and leaks out of the pipe wall and strategically placed sensors can accurately measure the three-dimensional vector of the leakage field.

Because magnetic flux leakage is a vector and that a sensor can only measure one direction, any given probe must have three sensors to accurately measure the axial, radial, and circumferential components of an MFL signal.
