Storage tank walls and roofs have to be inspected regularly for corrosion. General corrosion, corrosion around liquid levels or welds and other mechanisms can attack the integrity of a tank. However, the inspection work can be difficult and expensive due to the enormous surface area, difficult access and obstacles.

SGS Industrial Services provides an innovative and effective inspection solution for difficult to access tank walls and roofs, called Remote Ultrasonic Inspection. With the help of a motorized tank wall scanner with magnetic wheels, carbon steel tanks can be tested for corrosion and weld defects. This method enables remote Line Scans, remote Spot Measurements, remote Time of Flight Diffraction (TOFD) Inspection and remote Visual Inspection with a steerable camera.

SGS Remote Ultrasonic Inspection has advantages over other inspection methods, as it does not require expensive scaffolding or cranes and can be implemented on tank walls, even those with obstacles, such as wind girders and overlapping plates. Furthermore, this ultrasonic inspection technique provides detailed and reliable data on real tank wall thickness with echo-to-echo measurements as required for any tank integrity assessment.
