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.
SubDivo Inspection Services Division provides competent inspectors with the capability to choose the right method to solve the inspection or testing challenge any industrial project might face. Our innovative approach makes be sure of both safe operation and improved quality while reducing overall cost. SubDivo Inspection Service Division offers and performs shop or field inspections wherever required to any code, standard or customer specification.
SubDivo Strategy of assigning inspectors with rope access certification brings the project execution period 1/3rd and enhance safety performance.
The UT – Ultrasonic Testing includes the following Services;
Ultrasonic Testing (UT) Evaluates external flaws, wall thickness, and detection of internal flaws. This NDT Method uses high-frequency sound waves to measure the 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 is 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. SubDivo 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.
The MT – Magnetic Particle Testing includes the following Services;
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 PT – Liquid Penetrant Testing includes the following Services;
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. SubDivo Inspection Services Division offers 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.

The VT – Visual Testing includes the following Services;
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 the 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.
The ET – Electromagnetic Testing includes the following Services;
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.

The ACFM – Alternating Current Filed Measurement includes the following Services;
Alternating current field measurement (ACFM) is an electromagnetic technique used for the detection and sizing of surface breaking cracks in metallic components and welds. It combines the advantages of the alternating current potential drop (ACPD) technique and Eddy Current Testing (ECT) in terms of defect sizing without calibration and the ability to work without electrical contact respectively.
The Automated Ultrasonic testing – AUT can be deployed to the following Services;
Automated Ultrasonic inspection offers many benefits to our client base and is utilized on capital projects, maintenance inspection, turnaround scheduling/planning, and shutdown/turnaround/ outage situations.
Some of the factors that we consider when recommending the appropriate ultrasonic technology are the anticipated damage mechanism, operating condition of the asset, ability to access the area in question and the proximity of trade involvement to the inspection area.
The PAUT – Phased Array UT can be used for the following Services;
Phased array ultrasonic systems utilize multi-element probes, which are individually excited under computer control. By exciting each element in a controlled manner, a focused beam of ultrasound can be generated. The software enables the beam to be steered. Two and three-dimensional views can be generated showing the sizes and locations of any flaws detected.
The ToFD – Time of Flight Detraction inspection method includes the following Services;
Although time-of-flight diffraction (TOFD) can be used for a variety of applications, its primary use is rapid weld testing of circumferential and axial weld seams, also known as perpendicular TOFD scanning.
Long range ultrasonic testing is a rapid way of screening for corrosion in pipelines. The method enables screening of up to 100 meters of pipeline in one test, i.e. 50 meters in both directions.
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 the 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.
