Tank Base Corrosion Protection System in Saudi | Steelcoat TBP

Denso Steelcoat™ Tank Base Protection System (TBP) is a combined tape and liquid coating system designed to protect the external base area of aboveground steel storage tanks. The system creates a tough, flexible and weather-resistant seal around the tank base. It helps protect vulnerable areas such as the tank perimeter, weld area, lower wall and underside of the tank base.

Nassguard supplies the Tank Base Corrosion Protection System in Saudi Arabia, including Riyadh, Dammam, Jubail, Jeddah and Al Khobar.

What Is the Denso Steelcoat Tank Base Protection System?

The Denso Steelcoat Tank Base Protection System is designed specifically for corrosion protection around the base of aboveground storage tanks (ASTs).

Tank bases can face difficult corrosion conditions. Salt particles can collect around the tank. Rainwater and moisture can then carry these deposits down the tank wall toward the base. This can create corrosion around the tank perimeter, weld area, lower wall and underside of the tank base.

The Steelcoat system combines tape, mastic and liquid coating materials to encapsulate the tank base. The completed system creates a flexible protective seal that can accommodate movement as the tank fills and empties.

How the Denso Steelcoat Tank Base Protection System Works

• Surface preparation: Workers clean the tank base and concrete area and remove loose rust, scale, old coating and contamination.
• Primer application: Workers apply the specified primer to the prepared tank surface.
• Mastic application: Densyl Mastic helps fill gaps and provide a suitable profile around the base.
• First tape layer: Denso Hi-Tack Tape wraps around the prepared base area.
• Second tape layer: Denso Ultraseal RT Tape provides an additional protective layer.
• Topcoat application: A suitable Denso Urethane or Acrylic Topcoat completes the system.
• Flexible sealing: The finished system remains flexible and accommodates normal tank movement.

Why Tank Bases Need Corrosion Protection

The base of an aboveground storage tank can experience more severe corrosion than many other exposed areas.

Salt particles from the atmosphere can settle on tank surfaces. Rain and moisture can then carry these deposits toward the bottom of the tank. Water can collect around the tank perimeter and create conditions that promote corrosion.

Corrosion can affect the annular area, weld zone, lower tank wall and underside of the base. If workers leave the problem untreated, corrosion can lead to metal loss, perforation and costly repair work.

The Steelcoat TBP system provides a protective seal around this vulnerable area.

Protection Around the Tank Circumference

The system encapsulates the circumference of the tank base with a flexible protective layer.

This helps reduce direct exposure to moisture and environmental contaminants around the tank perimeter. The seal also follows the base profile and accommodates normal movement from tank filling and emptying.

Flexible Protection During Tank Movement

Storage tanks can move slightly as operators fill and empty them. A rigid seal can crack or lose contact when the tank moves.

The Denso Steelcoat Tank Base Protection System remains flexible during these cyclic movements. This helps the protective system maintain coverage around the tank base.

Protection for Existing Storage Tanks

One major advantage of the system is its suitability for existing tanks.

The application does not normally require excavation or tank lifting. The specified surface preparation also avoids the need for blast cleaning. This can reduce disruption during refurbishment work.

Workers can inspect the tank base, prepare the surface and install the protection system according to the project procedure.

Surface Preparation for Tank Base Protection

Correct preparation helps the system achieve good contact with the tank surface.

• Ensure the tank base and concrete base are dry and free from dirt.
• Remove grease deposits with a suitable cleaning method.
• Remove loose rust, scale and old flaking coatings.
• Use power wire brushes or scrapers for the specified preparation.
• Prepare the surface to St 2 where the application instructions require this level.
• Abrasive blast cleaning can be used when the project requires it.
• Inspect the prepared surface before applying the system.
• Repair or address deep defects where required.
• Ensure the surface remains clean before primer application.
• Follow the complete Steelcoat TBP application procedure.

Denso Steelcoat TBP System Components

The Tank Base Protection System uses several Denso products to create the complete protective assembly.

Denso Hi-Tack Primer: Denso Hi-Tack Primer prepares suitable steel surfaces before the petrolatum tape application. It helps establish contact between the prepared substrate and the tape system.

Denso Primer D: Denso Primer D provides an alternative primer option within the specified Tank Base Protection System.

Densyl Mastic: Densyl Mastic helps fill gaps and irregular areas around the tank base. It helps create a suitable profile before workers apply the protective tapes.

Denso Hi-Tack Tape: Denso Hi-Tack Tape provides the first tape layer in the specified system. Its flexible construction allows workers to wrap the tape around the tank base.

Denso Ultraseal RT Tape: Denso Ultraseal RT Tape forms the additional tape layer in the system. It helps create a robust outer protective barrier.

Denso Urethane or Acrylic Topcoat: The Denso Urethane or Acrylic Topcoat completes the protective system and provides the specified external coating layer.

Application of the Denso Steelcoat Tank Base Protection System

The system follows a structured installation process.

• Inspect the tank base before starting the work.
• Remove dirt, grease, loose rust and old flaking coatings.
• Prepare the tank base and concrete surface as specified.
• Apply the selected primer to the prepared steel.
• Use Densyl Mastic around gaps and irregular areas where required.
• Apply the first layer of Denso Hi-Tack Tape.
• Maintain the required overlap during wrapping.
• Apply Denso Ultraseal RT Tape as the second tape layer.
• Maintain continuous coverage around the tank circumference.
• Apply the specified Denso Urethane or Acrylic Topcoat.
• Inspect the finished system for gaps, air pockets and incorrect overlaps.
• Correct any exposed areas before completing the work.
• Follow the project specification and application instructions throughout the installation.

Tank Base Protection Without Excavation

Traditional tank base repair can involve significant site disruption. Excavation, tank lifting and extensive surface preparation can increase project time and cost.

The Denso Steelcoat TBP System provides an approach that does not require excavation or tank lifting during normal application. This can make it suitable for refurbishment projects where minimizing disruption matters.

Tank Base Protection for New and Existing Tanks

The system can support both new tank installations and existing tank refurbishment.

For new tanks, the protection can form part of the planned corrosion-control strategy. For existing tanks, workers can use the system during maintenance and refurbishment after suitable inspection and surface preparation.

Protection for Slab and Ringwall Foundations

The system can suit aboveground storage tanks with slab or ringwall foundations, subject to operating temperatures.

The foundation arrangement should be assessed before installation. Workers should select the correct application configuration based on the tank design and project requirements.
