There are several competing technologies, and no NDT method can claim to do everything. Before considering buying a probe to inspect your tubes, here are the 5 things you should know.
- What are you looking for by carrying out tube inspections?
It is important to clearly know the defects that you are looking for as it is key in determining what inspection technology or combination of technologies are right for you. Here are a few commonly sought defects in tubing.
- Are you looking for defects inside or outside of your tube?
Depending on where – inside or outside the tube that you wish to inspect the tubes, plays a key role in selecting the type of tube inspection tool that should be used. Ask yourself these questions.
Are your tubes, surface breaking? Are they close under the inner diameter of the tubes? Are they close under the outer diameter of the tubes? Are they in welds? Are they around tube sheets or support plates?
- What material are your tubes?
Knowing that your tubes are made of stainless steel isn’t enough. Material properties can have a huge impact on certain inspection techniques. Therefore, knowing a material’s manufacturing standards is important.
- Physical dimensions of tube
Knowing the physical dimensions of your tubes helps in deciding the appropriate tube inspection tool, as not every technique is appropriate to every tube dimensions and thickness. So, before buying any tube inspection tool, make sure you are aware of these specifications.
- The inner and/or outer diameter of your tubes – preferred to know both
- The BWG or wall thickness of your tubes – preferred to know both
- Location of the tubes that has to be inspected
Other than the approximate location of the defects, you must take note of where the tubes that must go through inspection are placed in the industry. For example, if the tubes are located near a water source, using tube inspection tool such as IRIS, even though is successful, might just be impossible for inspection. Moreover, if location of tubes is in a cramped area it is unlikely that you would want to choose a giant inspection tool that will be hard to be moved around. Therefore, it is important to take note of the factors that will affect your decision to buying a tube inspection tool.

- Check for amount of space in your industry
- Number of tubes that must be inspected – the more the number of tubes that has to be inspected, it is important to find a tool which is able to conduct quick tube inspections. – APRIS is a tube inspection tool that can conduct inspections in 10 seconds.
We believe that this information will help to narrow and choose the perfect tube inspecting tool that is the most suitable for your industry.
