Prove SDT
The underground tank integrity detection system, accompanied by a specific software that records signals and returns them in a graphical format, detects the presence of perforation, allowing a rapid and efficient assessment of the state of the tank..
The test is performed by applying a slight vacuum to the tank so that any holes or cracks generate ultrasounds, detected by the SDT system.

One of the main advantages offered by this method is that the tank on which the system operates does not necessarily have to be empty. Also the system, working in depressurization, does not cause any overflow of product from the holes, thus avoiding possible pollution.
