Inspecting storage tanks, whether they are holding water, fuel, oil or almost anything else, needs to be done regularly and consistently to monitor for everything from small leaks to catastrophic failures. Steel tanks, in particular, are subject to corrosion, cracking and stress—particularly in and around the welds that hold the sections of the tanks together. A variety of techniques and technologies are regularly used, but remote visual inspection (RVI) and ultrasonic testing (UT) are the primary methods. Enter the MaggUT™ miniature magnetic crawler system… With an onboard Crystal Cam® video camera and an Olympus D790 UT probe, the MaggUT™ can be used both inside and outside steel tanks, whether that means climbing walls, driving on the roof or operating on the floor. Its vertical capability enables access to almost all areas of the tank, without the need for expensive scaffolding; a built-in couplant pump and hose allow for remote thickness measurements an almost any surface. And, because it includes industry standard UT technology, tank inspectors can use existing thickness gauges (like the Olympus 38DL PLUS, or EPOCH XT) to perform A or B-Scans, without having to go through any new training.
When your problems run deeper (underwater, we mean), check out the new MaggUT™ - Marine. This version of the crawler also includes a camera and a thickness probe, but it can be used in air or underwater to depths of up to 60 metres (200 feet). With a fully integrated Cygnus UT system, the MaggUT™ - Marine is ideal for ship hulls or FPSOs; inspecting through bare metal or coated steel is easy with the Cygnus single echo and echo-echo modes, and thickness readings are recording directly into Inuktun’s control software, ICON, for post inspection reporting.
Best of all, both systems are surprisingly affordable and come with useful options like the Spectrum 45™ pan and tilt camera for improved RVI capability, or a different chassis for operating inside of pipes. Contact your local Inuktun office today for more information!
