Radiographic Testing (RT) uses the short wavelength electromagnetic radiation passing through the material to behold for defect identification. The radiation, which reaches the film after passing through the material, forms a shadow image on photographic film (radiograph). Areas of low absorption (slag, porosity) appear as dark areas on the developed film (radiograph). Areas of high absorption (dense inclusions) appear as light areas on the developed film.
To perform industrial radiography, we utilize various X-ray machines and radioactive isotopes to record internal defects. IXAR is Equipped with the best X-ray crawler technology for 6” to 60” pipe and pipeline radiography and experienced personnel, we offer you the advantages of high radiography quality, high imaging sensitivity, low failure rate and high work efficiency.
In conventional radiography techniques, we use gamma radiation sources like Iridium-192, Selenium 75, Cobalt-60, Closed Proximity Radiation System and Real Time Radiography.
DIGITIZATION OF FILM:
At IXAR, we understand your need to have proper storage and easy accessibility to obtaining the films. That’s why we make the most of the latest technologies to meet your requirements. With KODAK LS75 and LS85 High-Resolution Laser Film Digitizer, we deliver high performance, image quality and reliability. In the process, our experts capture film images, which are later converted to high-resolution digital images. All in all, it ensures a high degree of precision, excellent density resolution and precision, and spatial resolution.
CLOSE PROXIMITY RADIOGRAPHY:
With a restricted area of radiation, Close Proximity Radiography significantly reduces the radiation risk and eliminates the need to evacuate the work area. So, the testing doesn’t affect the production targets and daily work schedules. Apart from making the most of the latest technology and systems, our personnel utilize SELENIUM-75 radioactive isotopes to provide high-quality radiographs.
Liquid Penetrant Testing (PT) reveals surface flaws in non-porous material and metallic and non-metallic surfaces by the “bleed-out” of penetrating medium against a contrasting background. This is done by applying a penetrant to the pre-cleaned surface and flaw of the item being inspected.
The penetrant is applied to the surface and allowed to remain on the surface for a prescribed time (dwell time); the penetrant liquid will be drawn into any surface opening by capillary action. Following the removal of the excess penetrant, an application of the developer reverses the capillary action and draws the penetrant from the flaw. The resultant indications reveal the presence of the flaw so that it can be visually inspected and evaluated.
Materials that can be inspected using LPT include; metals (aluminium, copper, steel etc.), rubber, glass, and plastics. The LPT is used only to detect surface defects including -
Lack of fusion along the edge of the bond line
Through this technique, our experts evaluate the condition and quality of a component. With a wide variety of penetrant materials and a custom-made fluorescent penetrant inspection system, we provide both field and lab testing, with high-volume processing of many different parts with both fluorescent and visible penetrants.
Magnetic particle Testing (MT) is used to locate surface and slightly subsurface discontinuities or defects in ferromagnetic materials. Such flaws present in a magnetized part will cause a magnetic field i.e. flux, to leave the part.
If the magnetic particles are applied to this surface, they will be held in place by the flux leakage to give a visual indication. A magnetic particle test will be conducted by creating a magnetic field in a part and applying the magnetic particles to the test surface.
Our experts utilize Magnetic Particle Testing to detect surface and near-surface flaws and defects. It is fast and relatively easy to apply, and surface preparation is not as critical as compared to other NDT methods. We offer both on-site and in-house services as per your requirements.
Ultrasonic Testing (UT) uses high-frequency sound waves (ultrasound) that are above the range of human hearing to measure geometric and physical properties of materials, and flaw detection/evaluation. Ultrasound travels through different materials at different speeds (velocity). The speed of sound propagation in a given material is constant. Our experts make sure this quick, non-intrusive and cost-effective inspection is also reliable with advanced testing equipment like Einstein TFT – II, Krautkramer's and others.
Ultrasonic Thickness Measurement
The use of Ultrasonic non-destructive testing (NDT) to check material properties such as thickness measurement is used in all facets of the industry. The ability to gauge the thickness measurement of material without access to both sides of the test piece offers this technology a multitude of possible applications.
Ultrasonic thickness gauge can be set up for metals, plastics, composites, fibreglass, ceramics & glass. It is completely non-destructive with no cutting or sectioning required.
Ultrasonic thickness measurement is done by gages by precisely measuring how long it takes for a sound pulse that has been generated by a small probe called Ultrasonic Transducer to travel through a test piece & reflect from the inside surface or for the wall.
Measurement is made from one side in "Pulse/echo" mode because sound waves reflect from boundaries between dissimilar metals. Ultrasonic thickness measurement is performed for the measurement of the thickness of Hot Metals, through coating and scale measurement of the inner surface of the pipe.
Visual Inspection Services (VI) is one of the oldest and primary Non-destructive Testing among all. It is simple, easy to apply, quickly carried out and charges a very low cost. Even though a component is to be inspected using other NDT methods, the visual test can reveal gross surface defects that lead to immediate rejection of components. The presence of finer defects is of utmost importance with a very high degree of precision.
The benefits of Visual Inspection Services are:
IXAR has expertise in performing Visual Inspection with the help of a Borescope and other devices such as filet weld gauges, undercut gauges, flashlight, ruler as well as a magnifying glass to determine various lengths, measurements and quality of welded parts and components to verify that products meet the requirements of the specifications. We offer visual inspection in the Oil and gas industries, aerospace and automotive sectors.
