Aboveground Storage Tank Repair

Aboveground Storage Tank Repair
Storage tanks are essential assets in various industries, serving as containers for storing liquids, gases, or bulk materials. Over time, these tanks may experience deterioration, corrosion, leaks, or other issues that require repair and maintenance to ensure their safe and efficient operation. This provides a comprehensive guide to storage tank repair, covering common problems encountered, necessary maintenance practices, and effective solutions to extend the lifespan of storage tanks.

Regular Inspections:

Regular inspections are vital to identify any signs of damage or deterioration in storage tanks. Inspections should include external and internal evaluations, checking for leaks, corrosion, structural weaknesses, and proper functioning of safety features. Inspections can be conducted by trained personnel or specialized inspection companies using various techniques such as visual inspection, ultrasonic testing, magnetic particle testing, or radiographic testing.

Common Issues with Storage Tanks:

a. Corrosion: Corrosion is a significant concern for storage tanks, particularly those holding corrosive substances. It can weaken the tank structure, leading to leaks and potential environmental hazards. Different types of corrosion, such as uniform, pitting, or stress corrosion cracking, require specific repair approaches.

b. Leaks: Leaks in storage tanks can result from corrosion, improper installation, or mechanical damage. They pose safety risks, environmental hazards, and can lead to product loss. Identifying the source of the leak and promptly addressing it is crucial.

c. Mechanical Damage: Storage tanks can suffer mechanical damage due to accidents, external impacts, or structural failures. These damages may include dents, cracks, or ruptures, jeopardizing the integrity of the tank and requiring immediate repair.

Repair Techniques and Solutions:

a. Corrosion Mitigation: Repairing corrosion involves identifying the affected areas, removing the corroded material, and applying protective coatings or linings to prevent further deterioration. Techniques such as abrasive blasting, chemical cleaning, or cathodic protection can be employed to address corrosion issues effectively.
b. Leak Repair: Repairing leaks often involves identifying the location of the leak, assessing the extent of damage, and applying appropriate repair methods. These methods may include welding, epoxy patching, sealants, or mechanical repair devices.

c. Structural Repair: In the case of mechanical damage or structural failures, repair techniques depend on the severity and location of the damage. Welding, reinforcing plates, or even tank replacement may be necessary to restore the tank's structural integrity.

Safety Considerations:

Safety should be a priority when conducting storage tank repairs. It is essential to follow industry standards, guidelines, and safety protocols during inspections and repair procedures. Adequate personal protective equipment (PPE) should be used, and workers must be trained in working safely in confined spaces and handling hazardous materials.


Proper maintenance and timely repair of storage tanks are crucial for ensuring their longevity, safety, and preventing environmental contamination. Regular inspections, prompt identification of issues, and employing appropriate repair techniques will help mitigate problems such as corrosion, leaks, and mechanical damage. By adhering to safety protocols and industry standards, storage tank operators can effectively address repair needs and extend the lifespan of these critical assets.Visit our website to know more https://www.commtank.com/services/storage-tank-repair/
