How to Use Non-Destructive Testing Techniques for Water Storage Tank Inspections

Tank inspection ensures the safety and integrity of aboveground storage tanks by preventing accidental leaks and avoiding costly decontamination, while also providing critical data for predicting lifetime and repair costs. New non-destructive testing (NDT) technologies are constantly being developed to improve defect detection and sizing accuracy.

Non-destructive inspection services refer to testing and inspection studies performed without causing damage to the material or structure in order to control the integrity, strength, impermeability, or impermeability of materials, parts, or structures that are normally inaccessible.

What is Non-Destructive Testing (NDT testing)?

Companies that store liquids should conduct regular inspections of all storage facilities. In addition to checking the appearance of your fuel on a regular basis, you should hire a qualified technician to conduct a more thorough inspection of your storage facilities.

The only way to determine a tank’s current ‘health status’ is through non-destructive testing (NDT). It employs measurement techniques to identify any damage or anomalies in the liquids stored within.

Magnetic-flux leakage (MFL) and ultrasonic testing (UT) are two methods for evaluating the quality of equipment walls without causing damage to them. Following analysis, you will be given a comprehensive report that can be used to satisfy insurance or regulatory inspections.

NDT testing should be carried out every 12-18 months.  

There is a wide range of NDT tests on offer to suit whatever your requirements, such as:

  • Ultrasonic inspection
  • Tank thickness testing
  • Tank weld testing
  • Tank base testing
  • UAV inspections
  • Hardness testing

What are the benefits of NDT testing?

  • Identifies areas of degradation before failure occurs to ensure longer life expectancy
  • Minimizes downtime to ensure maximum productivity of tanks
  • Offers trend information on deterioration so that predictions can be made
  • Gives you peace of mind that your fuel tank is in sound condition

What are the advantages of using NDT?

The most obvious advantage is that the pieces being tested are left undamaged by the process, allowing an item to be repaired rather than replaced if any problems are discovered.

It is also a very safe testing method for operators, with most techniques being harmless to humans, though some tests, such as radiographic testing, must still be carried out under strict conditions. This testing method can also help to prevent injury or fatalities by ensuring the safety of structures, components, and machinery.

Non-destructive testing is also a highly accurate method of inspection because the tests are repeatable and a number of tests can be used in conjunction to correlate results.

These testing methods are also cost effective. NDT, as opposed to destructive testing, is less expensive because it can prevent the need to replace an item before a malfunction occurs without destroying the piece itself.

This testing technique also provides operators with peace of mind by ensuring that equipment is functioning properly, preventing future accidents, and determining any measures that can be taken to extend life.

It is also useful for weld testing and verification to ensure that a welding process was completed to the correct specification within the bounds of quality control, such as ensuring that the base metal reached the correct temperature, cooled at the correct rate, and that compatible materials were used to prevent welding defects.

Many industries use non-destructive testing to evaluate the properties of a material, component, structure, or system without causing any damage. NDT includes visual inspection, radiography, ultrasonic testing, magnetic particle testing, and penetrant testing. Depending on the application, each type has distinct advantages.

Overall, nondestructive testing (NDT) is a versatile and useful technique for identifying problems or defects in materials or structures without causing any damage.
