Tracer-gas leak testing
Have you ever played a game of "Hide and Seek"? When you hide, you try to be as quiet and still as possible so that the seeker can't find you. But what if you were hiding and you accidentally let out a little sneeze or cough? That would make it easier for the seeker to hear you and find you, right?
Well, the same concept applies to finding leaks in things like pipes or tanks that carry gas, such as helium or hydrogen. The gas that's inside those pipes or tanks is like you hiding in a game of "Hide and Seek". It's invisible and can be hard to find.
But just like how a sneeze or cough can give away your hiding spot, there are special types of gases called tracer gases that can be added to the gas that's already in the pipes or tanks. These tracer gases are kind of like a secret code or a special mark that can help people find where the gas is leaking from.
So, how does this work? When the tracer gas is added to the gas in the pipes or tank, it will seep out of any leaks along with the gas that's supposed to be inside. Then, special tools can be used to "sniff" the air around the pipes or tank and detect the tracer gas. Once the tracer gas is detected, the person doing the testing can follow the gas trail back to the source of the leak.
It's like when you play a game of "Hot and Cold" and someone gives you clues to help you find where an object is hidden. The tracer gas is the clue that helps people find the leak.
So, that's basically what tracer-gas leak testing is. It's a way to find leaks in pipes or tanks by adding a special gas (the tracer gas) that can help people detect where the leaked gas is coming from.
