Leak Testing
Principle and Method
Leakage refers to leakage of fluid or inflow of other fluids from a airtight container, a storage facility, or pipe that contains a gas or a liquid by the pressure difference between the inside and outside of the test body, and is caused by the discontinuity of the test body.
At this time, the method of testing leakage or inflow of fluid or detecting the amount of leakage is called Leak Test.
