Extreme weather and tough conditions in Fort St. John, BC can put your pipeline at risk of corrosion. Corrosion is an inevitable occurrence when you are dealing with metal materials, but disaster isnâ€™t. NDT companies use techniques like X-Ray inspection to find corrosion and stop it from turning your pipeline into a headline.
How does corrosion happen?
Corrosion occurs naturally over time as the metal components of your pipeline react with the soil and water surrounding them. To a certain extent, corrosion is unavoidable. But the damage that it causes can be kept to a minimum when monitored correctly. NDT inspection and proper maintenance are key.
What are some of the signs of corrosion?
The certified NDT/NDE inspectors at 20/20 NDT look for known signs of corrosion, like:
- Thinning pipe walls
- Pitting and pinholes
- Hairline cracks
- Sand wash damage
- Other signs of distress
What does the NDT inspection process entail?
The inspection process varies based on your needs, but in addition to visual inspections, we will also perform one or more of the following NDT tests:
- Radiographic testingâ€”Using an X-Ray or gamma ray we can find cracks and porous areas in the pipeline wall.
- Ultrasonic testingâ€”Using high frequencies, this test can detect tiny flaws on both the inside and the outside of the pipe wall. It can be used on both ferrous and non-ferrous materials.
- Magnetic particle testingâ€”Using a dusting of iron particles, this test can detect surface cracks and structural weakness.
- Dye penetrant testingâ€”A special dye soaks into the pipe wall and then a developer is applied to highlight invisible flaws on the surface.
Each one of these tests provides immediate, measurable results. Youâ€™ll be given a detailed report on the integrity of your pipeline and any potential areas for concern. If corrosion is present, weâ€™ll find it.
Can corrosion be prevented?
Steel pipes that come into contact with water and soil will eventually rust. Thatâ€™s why pipeline operators often apply a layer of epoxy coating on pipes after they are welded and before they are lowered into the trench. Epoxy is a paint-like substance that inhibits corrosion.
If and when corrosion does occur, itâ€™s important to contact an NDT company in Fort St. John like 20/20 NDT and schedule an appointment without delay. Corrosion is the number one cause of pipeline failure in Canada, and shouldnâ€™t be left unchecked.
