NDT SOLUTION

DIGITAL RADIOGRAPHY INSPECTION

PHYSICAL: TCR's state-of-the-art laser alignment devices, microprocessor controlled x-ray machines and automatic film processors, ensure high quality, rapid speed, and hence offer the most efficient radiographic services in the industry.

 

DIGITAL USING COMPUTER AIDED RADIOGRAPHIC TESTING (CART): TCR with its computer-aided generation of radiographic images, uses linear array detector systems in place of traditional film. The CART Industrial Inspection System works on the basis of differential densities. When a product passes through the conveyor system, a grey scale X-Ray image of the product is created. Different densities/thicknesses show up in the image as shades of grey. The image is captured from the data and displayed through the control panel monitors. It offers several Image enhancement controls including zoom, contrast, brightness, etc. Advanced Software Algorithms clearly and accurately highlights discontinuities in the image in order to qualify samples as per standards.

VISUAL INSPECTION SERVICES

At TCR, non-destructive visual inspections are performed on-site or at the laboratory facility based on the requirements of the client and as per their specifications. Industries utilizing this service include Fabrication, Construction, Automotive, Power Generation and Transportation. Inspections can be performed at the laboratory facility or onsite. These inspections are performed to meet IS, BS, ASTM, AWS, ASME (American Society for Mechanical Engineers) and many other standards

ULTRASONIC INSPECTION

Ultrasonic methods of NDT employs the use of beams of sound waves (vibrations) of short wavelength and high frequency that is transmitted from a probe and detected by the same or other probes. Usually, pulsed beams of ultrasound are used and in the simplest instruments a single, handheld probe is placed on the specimen surface.


An oscilloscope display with a time base shows the time it takes for an ultrasonic pulse to travel to a reflector (a flaw, the back surface or other free surfaces) in terms of distance traveled across the oscilloscope screen. The height of the reflected pulse is related to the flaw size as seen from the transmitter probe. The relationship of flaw size, distance and reflectivity are complex, and a considerable skill is required to interpret the display.

 

At TCR, complex multi-probe systems are also used with mechanical probe movement and digitization of signals, followed by computer interpretation.

Ultrasonic examinations are performed for the detection and sizing of internal defects, flaws or discontinuities in piping, castings, forgings, weldments or other components. Exact sizing techniques have been developed to detect and monitor progressive cracking in a variety of equipment.

 

TCR has in-house capability to undertake Automated UT using Time of Flight Diffraction technique (ToFD) as per code case 181 for piping, code case 2235 for pressure vessels and API 650 appendix U for storage tanks.

MAGNETIC PARTICLE INSPECTION

The Magnetic Particle Inspection method of Non-Destructive testing is a used by TCR for locating surface and subsurface discontinuities in ferromagnetic material. Depending on its operation on the face when the material or part under test is magnetized, discontinuities that lie in a direction generally transverse to the direction of the magnetic field. This causes a leakage field, and therefore, the presence of the discontinuity is detected by using finely divided ferromagnetic particles applied over the surface, some of these particles being gathered and held by the leakage field. This magnetically held collection of particles forms an outline of the discontinuity and indicates its location, size, shape and extent.


 

At TCR, dry magnetic particle examinations and wet fluorescent magnetic particle examinations are performed on ferromagnetic materials to detect surface and slightly subsurface discontinuities. Specialized wet fluorescent magnetic particle techniques are available for black light internal examinations of equipment through borescopes.

LIQUID PENETRANT EXAMINATION

HOLIDAY DETECTION

Holiday Detection or a Continuity Test is one of the Non-Destructive Test methods applied on protective coatings to determine any imperfections and breaks in continuity. TCR Arabia performs the test by using a low voltage to check if current flows in a complete electrical circuit. When a pinhole or void is detected in the coating the circuit is completed and a signal given out. Holiday Detection is commonly used in the oil and gas industries where piping and structures are coated with non-conductor coatings. However, it has since been adapted for testing waterproofing membranes on roofing systems, bridge decks and even car park surfaces.

ROUGHNESS TESTING

TCR Arabia performs surface roughness testing on linear surfaces. Our equipment can provide the characteristics of a material's surface variation. Depending on the size of these deviations the surface will either be rough or smooth. A very rough surface will interact differently with other materials due to the coefficient of friction. This may be undesirable when a contact between two parts must be smooth. However, manufacturing a very fine surface is more costly. The application of the parts and their interactions to surface condition will ultimately determine the desired surface roughness.

OXIDE SCALE MEASUREMENT

TCR Arabia does Internal Oxide Scale Boiler Measurement. The high-temperature operation of steam boilers (in excess of 10000F or 5000C) can cause the formation of a brittle iron oxide called magnetite on the inside surfaces of tubing. It reduces heat transfer and increases operating tube wall temperature. This shortens the creep life of the tube. If detected in time, it can help for de-scaling decisions to increase the life and efficiently. It is possible to judge the remaining life of the boiler tube by measuring internal oxide scale.

NDT SOLUTION

Radiographic Testing

Industrial radiography is a method of non-destructive testing where many types of manufactured components can be examined to verify the internal structure and integrity of the specimen. Industrial Radiography can be performed utilizing either X-rays or gamma rays. Both are forms of electromagnetic radiation. The difference between various forms of electromagnetic energy is related to the wavelength. X and gamma rays have the shortest wavelength and this property leads to the ability to penetrate, travel through, and exit various materials such as carbon steel and other metals.

Benefits

  • Can inspect assembled components

  • Minimum surface preparation required

  • Detects both surface and subsurface defects

  • Provides a permanent record of the inspection

  • Verify internal flaws on complex structures

  • Isolate and inspect internal components

  • Automatically detect and measure internal flaws

  • Measure dimensions and angles within the sample without sectioning

  • Sensitive to changes in thickness, corrosion, flaws and material density changes

Applications

Radiographic Testing is widely used in the:

  • Aerospace industries

  • Military defense

  • Offshore industries

  • Marine industries

  • Power-gen industries

  • Petrochem industries

  • Waste Management

  • Automotive industries

  • Manufacturing industries

  • Transport industries

Paint & Coating Thickness

Compared to other NDE techniques, radiography has several advantages. It is highly reproducible, can be used on a variety of materials, and the data gathered can be stored for later analysis. Radiography is an effective tool that requires very little surface preparation. Moreover, many radiographic systems are portable, which allows for use in the field and at elevated positions.

 

Conventional radiography uses a sensitive film which reacts to the emitted radiation to capture an image of the part being tested. This image can then be examined for evidence of damage or flaws. The biggest limitation of this technique is that films can only be used once and they take a long time to process and interpret.

 

In Radiography Testing the test-part is placed between the radiation source and film (or detector). The material density and thickness differences of the test-part will attenuate (i.e. reduce) the penetrating radiation through interaction processes involving scattering and/or absorption. The differences in absorption are then recorded on film(s) or through an electronic means. In industrial radiography, there are several imaging methods available, techniques to display the final image, i.e. Film Radiography, Real-Time Radiography (RTR), Computed Tomography (CT), Digital Radiography (DR), and Computed Radiography (CR).
