• Petrolatum wrapping: The specified petrolatum tape provides the primary corrosion-protection layer.
• Outer reinforcement: Denso Ultraseal Tape or Ultraseal RT provides an additional protective layer.
• Topcoat protection: Two coats of Denso Acrylic Topcoat finish the specified system.
• Continuous coverage: Correct overlap helps maintain consistent protection around the steel.

Steelcoat 100/400(A) for Pitted and Rusted Steelwork

Steelcoat 100/400(A) is designed for badly pitted and rusted pipework and structural steelwork.

For suitable pipework applications, the system starts with Denso Hi-Tack Primer, followed by a double wrap of Denso Hi-Tack Tape with the specified overlap. The outer Denso Ultraseal Tape or Ultraseal RT then provides additional protection before the final topcoat.

For structural steelwork, the system uses the specified wrapping arrangement to provide continuous protection across the prepared steel.

Steelcoat 100/400(B) for Damp or Sweating Pipework

Steelcoat 100/400(B) is intended for damp or sweating pipework surfaces.

For this application, Denso Paste S105 replaces the standard primer used in the A variation. This makes the combination system suitable for selected pipework where surface moisture presents a challenge during corrosion-protection work.

The remaining wrapping and outer protection arrangement follows the specified system.

Protection for Pitted Steel Pipe

Deep pits and surface irregularities can make conventional corrosion coatings difficult to apply evenly.

Denso Steelcoat 100/400 uses suitable profiling materials before the wrapping layers are applied. This helps workers deal with voids, fittings and irregular profiles before completing the corrosion-protection system.

The approach provides a flexible alternative for maintenance projects involving deteriorated steel pipework.

Rusted Steelwork Corrosion Protection

Existing structural steel can develop significant corrosion after prolonged exposure to moisture and industrial conditions.

The Steelcoat 100/400 combination provides a surface-tolerant approach for suitable rusted steelwork. Workers first remove loose corrosion and other weak material before applying the selected system.

The flexible wrapping and outer fabric-backed layer then provide additional protection around the prepared structure.

Damp Pipe Wrapping System

Damp and sweating pipework can create difficulties during corrosion-protection work. The Steelcoat 100/400(B) variation addresses this type of application.

Denso Paste S105 provides the specified primer layer for damp pipework before workers apply the petrolatum tape and outer protection layers.

This makes the system suitable for selected pipework where achieving a completely dry surface is difficult.

Above-Ground Pipe Corrosion Protection

Above-ground pipes can face continuous exposure to humidity, moisture, rain, salts and industrial contaminants.

The Steelcoat 100/400 system provides a flexible wrapping arrangement for suitable exposed pipework. It can follow straight sections, bends and fittings while providing a multi-layer protection system.

This makes it useful for maintenance and corrosion-control projects where the pipe surface already shows significant deterioration.

Structural Steelwork Corrosion Wrapping

Structural steel around industrial facilities and pipebridges can contain angles, supports, beams, brackets and connections.

These profiles can create difficult areas for conventional coatings. The Steelcoat 100/400 system combines flexible wrapping with profiling materials and outer protection to help cover suitable irregular steelwork.

Petrolatum Tape System for Difficult Applications

The petrolatum components provide the main corrosion-protection layer in the Steelcoat 100/400 arrangement. Their flexible construction allows workers to wrap suitable steel surfaces without heating.

The outer fabric-backed tape and topcoat add further protection to the completed system.

Surface Preparation and Application

Proper preparation helps the Denso Steelcoat 100/400 System achieve consistent coverage.

• Remove loose rust, scale and flaking coatings.
• Use hand tools to prepare the steel surface.
• Remove oil, grease, dirt and other contamination.
• Inspect the surface for deep pits and voids.
• Use suitable profiling mastic where required.
• Select variation A or B according to the surface condition.
• Apply the specified primer or paste.
• Apply the petrolatum tape with the required overlap.
• Maintain consistent wrapping tension.
• Cover bends, fittings and irregular profiles carefully.
• Apply the specified outer Ultraseal Tape or Ultraseal RT.
• Maintain the required overlap for the selected application.
• Apply the specified Denso Acrylic Topcoat.
• Inspect the finished system before returning the asset to service.

Denso Profiling Mastic for Pitted Areas and Fittings

Badly pitted surfaces, flanges and fittings can leave voids beneath a wrapping system.

Denso Profiling Mastic can help fill suitable voids and create a smoother profile before the wrapping layers are installed. This makes it easier to achieve continuous coverage around irregular shapes, flanges and fittings.

Outer Protection and Topcoat

The Steelcoat 100/400 system uses Denso Ultraseal Tape or Ultraseal RT as the outer layer in the specified arrangement.

After application, the fabric-backed outer tape receives two coats of Denso Acrylic Topcoat. This creates the finished external protection layer and helps protect the underlying wrapping system.

Denso Steelcoat 100/400 for Pipebridge Protection

Pipebridges often combine exposed pipelines with supporting structural steel. Access can be difficult, and the steel can face long-term exposure to environmental conditions.

The Steelcoat 100/400 System provides a suitable combined approach for these difficult areas. It can protect both pipework and structural steelwork when workers select the appropriate system variation and follow the application requirements.
