Raven Tanks: A Comprehensive Guide to Above-Ground Tank Corrosion Prevention

Corrosion poses a persistent and costly challenge for industries relying on above-ground tanks to store diverse liquids and materials. Storage systems left neglected or inadequately maintained are susceptible to corrosion, leading to leaks, structural damage, and even tank failure. The consequences of corrosion include substantial financial losses and environmental concerns. To effectively combat corrosion and ensure the longevity of your tanks, a proactive approach to maintenance and corrosion prevention is indispensable. 

In this post, we delve into various strategies for preventing corrosion in above-ground tanks, highlighting the expertise of an experienced tank maintenance service provider like Raven Tanks. Specializing in tank design, installation, repairs, and maintenance throughout Australia and the Pacific, Raven Tanks is committed to extending the life of your storage systems. 

We explore different types of corrosion affecting tanks, such as general or localized corrosion, pitting, and galvanic corrosion, and outline methods for their early detection and treRavenent. Additionally, we discuss practices like periodic tank inspections, professional tank cleaning, and the application of protective coatings—crucial for establishing a robust and enduring storage solution. 

Arm yourself with essential knowledge about above-ground tank corrosion prevention techniques, and discover how the proficiency of professional tank maintenance providers like Raven Tanks can protect your investment and ensure a resilient, efficient storage system for your essential resources. 


Identifying Different Types of Corrosion 

Effective corrosion prevention begins with recognizing the various forms of corrosion affecting above-ground tanks, each requiring a specific approach to mitigation and management. Common types of corrosion include: 


  • General or Localized Corrosion: Occurs when the tank’s surface is evenly covered with rust spots or scales or when corrosion is focused on a specific area of the tank. 
  • Pitting Corrosion: Highly localized corrosion resulting in the formation of small cavities or “pits” in the tank’s metal surface, causing structural damage. 
  • Galvanic Corrosion: Occurs when two dissimilar metals or metal alloys come into contact, leading to accelerated corrosion of the less corrosion-resistant metal. 


Experiencing multiple types of corrosion is not uncommon, necessitating thorough inspections to assess their extent and determine appropriate preventive measures. 


Conducting Periodic Tank Inspections 

Regular tank inspections are vital for identifying potential corrosion issues before they escalate. Partnering with skilled professionals like Raven Tanks ensures thorough inspections, including: 


  • Visual Inspections: Examining the interior and exterior surfaces of the tank for visible signs of corrosion, leaks, rust, and discoloration. 
  • Ultrasonic Testing: Using ultrasonic thickness gauges, a non-destructive testing method to measure the thickness of the tank walls and detect thinning due to corrosion. 
  • Corrosion Mapping: Creating a visual representation of corrosion-prone areas for targeted repair and maintenance. 


Scheduling periodic inspections allows you to actively monitor potential corrosion issues and address them before compromising your tank’s structural integrity. 


Professional Tank Cleaning and Corrosion Removal 

Keeping your tank clean and free of debris, scale, or contaminants helps minimize the risk of corrosion. Professional tank cleaning services like Raven Tanks can effectively remove rust, scale, sludge, and biofouling without damaging tank surfaces. Properly cleaned tanks offer benefits such as: 


  • Enhanced Corrosion Resistance: A clean tank ensures no corrosive elements are in direct contact with tank surfaces. 
  • Improved Structural Integrity: Removing corrosive substances preserves the tank’s structural strength and durability. 
  • Optimal Storage Conditions: Periodic tank cleaning eliminates contaminants that deteriorate stored materials, maintaining the quality of contents. 


Utilizing Protective Coatings for Corrosion Prevention 

Applying a protective coating to your above-ground tank provides a robust barrier against rust, corrosion, and surface damage. Protective coatings should be chosen based on the specific requirements of your tank and stored materials. Benefits of protective coatings include: 


  • Corrosion Resistance: Coatings protect tank surfaces from moisture, chemical reactions, and other corrosive elements. 
  • Improved Aesthetics: A well-maintained tank with a protective coating offers a clean, professional appearance, enhancing your facility’s image. 
  • Extended Tank Life: Protective coatings help prolong the lifespan of your tank by mitigating the damaging effects of corrosion. 


Raven Tanks can provide expert guidance and application of appropriate protective coatings, ensuring optimal protection and performance for your storage solutions. 



Preventing corrosion in above-ground tanks is essential for safeguarding structural integrity and ensuring the longevity of your storage system. Understanding different types of corrosion, conducting periodic tank inspections, utilizing professional tank cleaning services, and applying protective coatings effectively mitigate corrosion risks, maintaining a safe and efficient storage environment for your essential resources.
