Acoustic Emission Testing
Most weldments of steel pipes in energy sector require some method of testing to determine the quality of the welding. A common method of testing is by radiographic examination. Radiographic testing aims to record images of flaws introduced into the welds. These could be process defects (e.g. porosity, lack of fusion) or service-related conditions (e.g. corrosion-cracks).
Radiographic inspection is carried out utilizing radioactive sources such as Ir-192, Se-75 or Co-60 and also with X-ray irradiating apparatus. Our technicians are highly experienced not only in the use of these radioactive sources and X-Ray equipment but also take pride in holding a clean safety record on all projects undertaken.
Ultrasonic Testing
UT inspection is carried out on configurations of welds, whereby due to geometry and restricted access to either side of the area to be inspected, radiographic examination cannot be done, or where UT is known to exhibit better detection capability. An ultrasonic wave is sent into the material and the reflected wave is then analyzed. Flaws can be recognized by trained personnel on the instrument screen. Features of the flaw (like location, orientation, length, depth and height of the flaw) can then be identified and assessed.
This method of inspection holds advantages of detecting defects such as lamination and fusion-related defects for which radiographic examination is known to have lower probability of detection.
Visual Testing
This is the oldest and most common nondestructive testing (NDT) techniques. It is typically the first step in the examination process to inspect a variety of product forms including castings, forgings, machined components and weld elements, according to the NDT Training & Test Center
OTHER INSPECTION SERVICES
Our company also provides other methods of inspection such as UT Thickness Gauging, Hardness Testing and Holiday Detection. Besides testing services, we also offer third party engineering inspection, quality assurance, quality control and certification services. Our range of services will in future include the supply of specialist manpower ranging from engineers to multidiscipline inspectors and comprehensive programs for heat exchanger maintenance & inspection.
