Radiographic Testing (RT) is a form of traditional non-destructive examination that is used to inspect the internal structure of assets in the oil & gas, power generation, manufacturing, and aerospace industries.
Radiographic Testing is an an extremely popular inspection technique, thanks to its versatility in detecting a wide range of defects on multiple materials, and its ability to produce a permanent record of each inspection.
Ultrasonic Testing (UT) inspection is utilized for the detection and location of discontinuities, material composition analysis, and wall thickness measurements.
Ultrasonic Thickness Testing (UTT) is a method for determining the extent of corrosion and erosion on the walls of piping, vessel, storage tank, and other assets. We offer UTT spot inspections, and long-term, remote wall thickness monitoring for pipes and vessels in high-temperature and hard-to-access locations.
Eddy Current Testing
Magnetic Particle Testing
In Magnetic Particle Testing (MT), technicians magnetize a ferromagnetic material and apply finely-milled iron particles coated with a dye pigment to it. The particles indicate discontinuities in the material by clustering directly over it, which can be visually detected under proper lighting conditions.
Southern Services Inc. offers dry powder and wet fluorescent MT inspection services, depending on the application.
Liquid Penetrant Testing
Liquid Penetrant Inspection (PT) or dye penetrant testing – is based on the properties of surface wetting and capillary action, which causes a liquid to rise when confined to a small opening. After applying the penetrant and wiping away the excess, the penetrant that rises to the surface can indicate surface-breaking anomalies.
PT inspection services are widely applicable to identify discontinuities in a variety of assets given its ease of use and minimal equipment requirements.
