Infrared thermography (IRT), thermal imaging, and thermal video are examples of infrared imaging science. Thermographic cameras usually detect radiation in the long-infrared range of the electromagnetic spectrum and produce images of that radiation, called thermograms. IRT shows a visual picture so temperatures over a large area can be compared. It is capable of catching moving targets in real time, Thermal Imaging is able to find deterioration, i.e., higher temperature components prior to their failure. It can be used to measure or observe in areas inaccessible or hazardous for other methods. It is a non-destructive test method and can be used to find defects in shafts, pipes, and other metal or plastic parts. IRT can be used to detect objects in dark areas.
Ground Penetrating Radar
Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. This non-destructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum, and detects the reflected signals from subsurface structures. GPR can have applications in a variety of media, including rock, soil, ice, fresh water, pavements and structures. In the right conditions, practitioners can use GPR to detect subsurface objects, changes in material properties, and voids and cracks. GPR uses high-frequency (usually polarized) radio waves, usually in the range 10 MHz to 2.6 GHz. A GPR transmitter and antenna emits electromagnetic energy into the ground. When the energy encounters a buried object or a boundary between materials having different permittivities, it may be reflected or refracted or scattered back to the surface. A receiving antenna can then record the variations in the return signal.
Heat Treatment is the controlled heating and cooling of metals to alter their physical and mechanical properties without changing the product shape. Heat treatment is sometimes done inadvertently due to manufacturing processes that either heat or cool the metal such as welding or forming.
EIS Offers the following Heat Treating methods:
- Post Weld Heat Treatment,
- Normalizing and Quenching ro name a few.
EIS uses only state of the art equipment such as Stork 50 Kva machines, 2 x diesel fired furnaces and/or gas fired burners to meet the requirements of our clients.
We pride ourselves in employing only trained professionals with minimum of 3 years experience to ensure the highest quality and complete satisfaction for our clients.
We also provide Heat Treatment Training to the youth as a community development program for those interested in learning the profession.
Ultra Sonic Inspection
Ultrasonic non-destructive testing, also known as ultrasonic NDT or simply UT.
It’s a method of characterizing the thickness or internal structure of a test piece through the use of high frequency sound waves. Ultrasonic Inspection is a very useful and versatile NDT method. Some of the advantages of ultrasonic inspection that are often cited, include:
- It is sensitive to both surface and subsurface discontinuities.
- The depth of penetration for flaw detection or measurement is superior to other NDT methods.
- Only single-sided access is needed when the pulse-echo technique is used.
- It is highly accurate in determining reflector position and estimating size and shape.
- Minimal part preparation is required.t
- Electronic equipment provides instantaneous results.
- Detailed images can be produced with automated systems.
- It has other uses, such as thickness measurement, in addition to flaw detection.
- As with all NDT methods, ultrasonic inspection also has its limitations, which include:
- Surface must be accessible to transmit ultrasound.
- Materials that are rough, irregular in shape, very small, exceptionally thin or not homogeneous are difficult to inspect.
- Cast iron and other coarse grained materials are difficult to inspect.
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 system uses flow frequency guided ultrasonic waves to inspect tens of metres of pipe from a single remote location. The ability of this system to send waves along the length of the pipe, means that, very difficult to inspect areas, such as crossings, can be interrogated from a remote & easily accessible location can usually be performed while the pipe is in service.
Magnetic Flux Leakage Inspection System
Magnetic flux leakage is a magnetic method of non-destructive testing that is used to detect corrosion and pitting in steel structures, most commonly pipelines and storage tanks. the basic principle is that a powerful magnet is used to magnetize the steel to detect and size floor corrosion for above storage tanks.
RFD Rain Inspection
Digital Ultrasonic Rail Flaw Detector is a newly developed digital ultrasonic equipment of flaw detection. It is used to detect all kinds of flaws in rails materials ranged from 43kg/m – 75kg/m. It is a new type of practical & reliable instrument in rail flaw detection.
Phased Array Weld Inspection
Phased Array is at the heart of manual and semi automated weld inspection solutions which is developed for the Oil & Gas industry. These systems can be used for inspection in compliance with ASME, API and other code criteria, while offering high speed detection capabilities and facilitating indication interpretation.
