How Can Storage Tanks be Made to Last? By Understanding Why They Fail!
Storage Tank Failure Analysis and Corrosion Consulting
Storage tanks are subject to a wide range of stresses and corrosive conditions, including those from the liquids being stored, the soil around the tank, and from microbes with many different sources. Our experts can help you understand, analyze and prevent storage tank corrosion.
Why Do Storage Tanks Corrode?
Corrosion can be due to cause by issues with construction, fabrication, welding, and may accelerated by microbial colonies, corrosive chemicals, and even water. For example, recent research has shown that a vast majority of diesel storage tanks exhibit moderate to severe corrosion even when no corrosion is expected. The most common causes were due to the presence of water, biofuels, and microbial corrosion (MIC). It’s important to determine the culprit correctly in order to make a remediation and prevent it from occurring again.
Our team’s extensive experience in failure analysis helps us distinguish microbial corrosion from other causes, and then we can help you incorporate the right mitigation plan. We rely on a variety of common tools like electron microscopy, DNA testing, and x-ray diffraction to help confirm our analyses.
How to Evaluate Storage Tank Corrosion and Integrity?
There are numerous ways to evaluate storage tank corrosion, including visual and nondestructive testing, on-site measurements, and laboratory testing practices. Once significant corrosion has occurred, a failure analysis of the tank
Various guidelines exist for storage tank analysis:
- API 570 – Piping Inspection Code
- API 575 – Inspection of Atmospheric and Low-Pressure Tanks
- API 653 – Tank inspection, repair, alterations, and reconstruction
- STI SP001 – Standard for Inspection of Above ground Storage Tanks and
- UL 142 – Steel Aboveground Tanks for Flammable and Combustible Liquids
