Interior Tank Coatings

Interior Tank Coatings

For Crude Oil Storage Tanks

The inside of a crude oil storage tank is exposed to hydrocarbons, moisture, sediment, and other harsh materials that can gradually damage steel surfaces. Internal tank coatings create a protective barrier between the tank interior and stored materials, helping control corrosion and preserve the condition of the vessel over time.

At Metercheck, we provide interior tank coating solutions based on the specific requirements of each storage tank. Tank size, stored product, operating conditions, existing corrosion, and previous coating systems can all influence the preparation and coating process. Our team focuses on creating a durable, consistent coating system that supports long-term tank protection.

Preparing the Tank Interior

Proper preparation is one of the most important parts of any tank coating project. Before applying a new coating, the interior surface needs to be free from oil residue, sludge, rust, loose coatings, and other contaminants that could prevent proper adhesion.

Metercheck can coordinate the necessary cleaning and abrasive blasting to prepare the steel surface. Blasting removes deteriorated coatings and corrosion while creating the surface profile needed for the new coating system. During preparation, areas such as pits, welds, seams, and damaged steel can also be identified for further evaluation or repair.

Environmental conditions are carefully considered during coating application. Temperature, humidity, ventilation, and surface conditions can affect how a coating performs. Maintaining appropriate conditions helps the coating cure properly and achieve consistent coverage throughout the tank.

Choosing the Appropriate Coating

Every tank has different service requirements, which means one coating system may not be appropriate for every application. Factors such as chemical exposure, abrasion, temperature, stored material, and expected service conditions should be considered when selecting internal tank coatings.

Metercheck evaluates the project requirements to help determine an appropriate coating approach. The selected system should provide suitable resistance to the conditions inside the tank while maintaining strong adhesion to the prepared steel surface.

Application quality is equally important. Our crews pay close attention to coating thickness, coverage, welds, seams, edges, and other areas where inadequate coverage could leave steel exposed. Consistent application helps reduce coating defects and supports dependable protection.

Protecting Tank Integrity

Interior coating can play an important role in a broader tank maintenance program. By creating a protective layer over properly prepared steel, internal tank coatings can help reduce direct exposure to corrosive materials and support the long-term condition of the tank.

Coating work can also be scheduled alongside inspections, repairs, and other maintenance activities. Combining these services during planned tank downtime can help operators address multiple maintenance needs while the tank is already out of service.

Metercheck approaches each project with attention to surface preparation, coating selection, application, and quality control. Whether an existing coating needs to be removed or a tank requires a new protective system, our team works to provide a clean, properly coated interior ready for continued service.

Safety During Interior Coating Projects

Tank interiors can present confined-space, vapor, ventilation, and material-handling hazards. Metercheck incorporates appropriate safety procedures throughout the project, including controlled access, ventilation, personal protective equipment, and safe handling of blasting and coating materials.

Proper ventilation is particularly important during coating application and curing. Our crews work in a controlled manner to maintain suitable working conditions while completing the project efficiently.

From initial surface preparation through the final coating application, Metercheck focuses on safety and quality. Properly installed internal tank coatings can provide an important protective layer for crude oil storage tanks while supporting ongoing inspection, maintenance, and asset-management goals.
