We use the specialist “Fluorescent Liquid Penetrant Inspection” for testing tanks and vessels. The Fluorescent liquid penetrant inspection is also known as dye testing. Dye penetrant testing can be used in a wide range of industries on a vast array of equipment and parts.
Dye testing is the most efficient and reliable method for testing stainless steel tanks. It is a food safe penetrant that is non-toxic and biodegradable.
We also offer colour contrast methods of non-destructive testing (NDT).
This liquid penetrant inspection finds any surface connected discontinuities such as cracks from fatigue, quenching, and grinding, as well as fractures, porosity, incomplete fusion, and flaws in joints. Detecting faults early can reduce the risk of potential contamination.
How Tank Testing Works
Firstly, for our NDT technicians to carry out a dye test the customer would need to make sure that the process vessel or tank is clean and dry.
- Using the correct safety equipment the technicians will spray the inside of the tank using a fluorescent dye with a pressure sprayer.
- The dye is left on the inside of the tank or vessel for around 20 minutes – 1 hour depending on the size
- Fluorescent dye is used to reveal surface-breaking defects using a UV light in a darkened area.
- Following inspection full certification will be issued and should any defects be found our NDT technicians will advise of any necessary repair work required
- Tried & tested reliable method
- Routine inspections help reduce the risk of contamination
- Confined space trained technicians
- Spray heads / Agitators checked for signs of damage or restriction if required
- Report & certification provided
