Storage tanks, vessels, pipe work, and other safety-critical components are designed to contain liquids, gases, and solids so that loss-of-product do not occur. Leaks or the mechanical structural failure of this equipment may result in a major accidents on site.
The presence of hidden flaws, cracks, and corrosion in critical components may result in compromising the integrity of these systems, which increases the likelihood of failure.
Non-destructive testing (NDT) offers solutions to draw information on the current health of storage tanks, vessels, or pipe work without damaging them. Such techniques as magnetic-flux leakage (MFL) and ultrasonic testing (UT) enable assessing the integrity equipment walls without damaging them (such as in sectioning) and providing reliable and cost-effective inspection programs.
When performed correctly, NDT can yield critical information to assist in the management of plant safety. If not, the results are likely to give a false impression of the integrity and safety of assets being inspected. Using the latest developments in NDT technology reduces the risks relating to poorly applied techniques and improves the quality of inspections by applying data recording and analysis with enhanced visualization of indications.
There are many national and international standards for NDT which must be reviewed before undertaking test programs. Working within these standards and using the correct techniques allows reaching safe and effective asset management.
