With highly trained personal and innovative inspection techniques, ALS is an industry leading provider of Tube Inspections.
Maintaining tube integrity in heaters, fin fan coolers, heat exchanges, boilers, and chillers, is critical for maintaining the optimised performance of the tube’s wider operating environment. ALS provides extensive tubular inspections, using industry leading non-destructive testing solutions, to ensure tube integrity is maintained.
Tube inspections are critical for detecting the common in-service defects of corrosion, erosion, pitting and thinning before they become costly or potentially dangerous concerns.
The tube inspection techniques employed by ALS’s trained experts include:
- Conventional Bobbin Eddy Current testing
- Eddy Current array testing
- Remote Field testing
- Near Field testing
- IRIS testing
- Magnetic Bias Eddy Current
- Video inspections
- Ball Micrometers
All the above techniques have application depending on the tube’s material, tube’s dimensions, and the defects that are being specifically monitored for. The defects position, whether internal or external, is another consideration when selecting the inspection method. In some applications multiple methods may be required.
Advantages of Tube Inspection
When quality tube inspections are performed, defects like corrosion, erosion, thinning and pitting can be definitively detected, and costly maintenance avoided. Of the tube inspection techniques employed, they all offer varying inspection times and accuracy of results. If careful planning is done prior to an inspection, and method selection is based on the identified damage to the detect, extremely reliable results can be achieved.
Data analysis can be done on-site or by remote means, ensuring a quick turnaround of results.
The ALS Approach
ALS’s specialist tube testing technicians have years of industry-specific experience and intensive knowledge of their craft. Having spent their entire careers performing tube inspections, they can achieve extremely high levels of reliability in both data collection and data analysis. This is achieved through a defined standardised set of testing and calibration set up parameters, as well as ensuring and knowing the correct calibration test samples and probes are used, are critical to achieving a reliable and accurate inspection.
