NDT SYSTEM 2Т

The 2Т system  Above Ground Storage Tank Floor Scanning System is based on the principles of Low Frequency Electromagnetic Technique (LFET). It is designed to quickly and accurately inspect ferrous above ground storage tank floors.

The 2T system uses scanners that have 16 or 64 pickup sensors equally spaced to scan flat surfaces covering 4 (102mm) and 13 (330mm) swaths per pass. A 16- channel/16-sensor scanner called the 2T., is used for hard to reach areas such as sumps/pumps and under heating coils and internal piping as well as the annular ring. A 32-channel/64-sensor scanner called the Mark II, is a workhorse used for intermediate or average sized tanks. All scanners work from one electronics platform and can be used interchangeably.

Other methods used for inspecting aboveground storage tanks are Magnetic Flux Leakage and Ultrasonic Testing. The Magnetic Flux Leakage method uses permanent magnets, which adds unnecessary weight. It also requires a cleaner floor surface (sandblast), which causes the customer to spend additional money for cleaning. In addition, Magnetic Flux Leakage cannot determine whether a flaw is on the top surface or bottom surface of the tank floor and cannot test through coatings. The U.T. method again requires a cleaner floor surface and is very time consuming due to the lack of surface area which can be scanned at a time.

Low Frequency Electromagnetic Technique on the other hand, does not use permanent magnets, requires minimal floor preparation, is lightweight (under 30 lbs), and is easy to handle and transport. It tests through coatings, determines top surface flaws from bottom surface flaws, and continues to show flaw responses even after the unit has stopped moving.

The 2Т system has many packages available based on your inspection needs. These other packages can include the Hawkeye system for weld inspection, the Viper crawler system for wall or shell inspection, and remotely operated scanners for tank roof inspection.
