The ability to test for tightness with an ultrasound detector is extremely powerful and versatile. It is the only way to ensure that underground storage tanks are air tight. But that isn’t all that ultrasonic tightness testing can be used on. In fact, there are many things that need to be air tight. Like the engine or cabin of a car, large shipping containers or the bearing housing in a paper production plant. When something’s tightness integrity deteriorates, one or two things can happen. Things can leak out, or things can get in. And whenever possible, it is advantageous to avoid either of these from happening.
Overtime the tightness integrity of underground storage tanks or other air tight compartments can deteriorate. Or… they were never air tight to begin with. This is why tightness testing is an essential maintenance task to be carried out on underground storage tanks to prevent wasteful, harmful to the environment leaks.
Underground tanks can prove tricky to test for tightness integrity due to their inaccessibility. But this shouldn’t affect their frequent and thorough inspections. Indeed, leaking underground storage tanks result in contamination of the surrounding soil, groundwater and surface water. Not to mention, the loss of resources through the leak.
Since 1995 SDT has been the world leader in underground tank tightness testing. SDT developed the most comprehensive and accurate system for performing underground tank tightness inspections. A method that various accrediting agencies in Belgium, France and the United States have tested and approved. This proven method has been used to perform thousands of inspections world-wide.
