tyhjiötestauksella

Tyhjiötestaus, also known as vacuum testing, is a non-destructive testing method used to detect leaks in enclosed structures or systems. It involves creating a vacuum within the object or system being tested and then monitoring for any pressure changes. A decrease in vacuum pressure indicates the presence of a leak, as external air or gas is entering the evacuated space.

The process typically begins by sealing the item under test and then evacuating it using a vacuum pump. Once the desired vacuum level is achieved, the pump is isolated, and the pressure is monitored over a specific period. Sensitive pressure gauges are used to detect even small leaks. In some applications, a tracer gas, such as helium, may be introduced into the surrounding environment. If a leak is present, the tracer gas will be drawn into the evacuated space, and specialized detectors can then pinpoint the location of the leak.

Tyhjiötestaus is a versatile technique employed across various industries, including aerospace, automotive, and manufacturing. It is commonly used for testing fuel tanks, pipelines, electrical components, and sealed packaging. The effectiveness of tyhjiötestaus lies in its ability to detect leaks that might be difficult to find using other methods, especially small or hidden ones. It is a reliable way to ensure the integrity and safety of sealed systems.
