The Applied Technical Services Family of Companies (ATS FoC) provides leak path detection for pressurized containers and pipelines.
What is a Leak Path?
A leak path is an unintended physical route through which fluid or gas escapes from a contained environment. Common causes include:
- Seal gaps
- Cracks
- Corrosion
- Improper installation
What is Leak Path Detection?
Leak path detection involves inspecting containers or pressurized systems to identify unintended fluid escape routes. Inspectors use various methods and technologies, including:
Ultrasonic Leak Detection
Ultrasonic leak detection identifies and locates high-frequency sounds produced by leaks.
Infrared Leak Detection
Technicians use thermal imaging cameras and sensors to detect energy emitted by leaking gas.
Penetrant Dye Leak Detection
Technicians apply a visible dye to one side of a component and observe whether it seeps through surface flaws.
Mass Spectrometer Leak Detection
Technicians use helium as a tracer gas to locate and measure leaks in a system.
Hydrostatic Leak Detection
Hydrostatic leak tests fill a vessel or pipe with water to identify points of water penetration.
