What Is Denso Protal 7900HT™?

Denso Protal 7900HT™ is a two-component, 100% solids epoxy coating for pipeline corrosion protection at elevated operating temperatures. Its formulation allows the coating to cure quickly when applied to hot pipe, helping contractors move to backfilling sooner.

The coating provides a high-build protective layer and can reach up to 1000 µm in one coat. Workers can apply it by brush or spray, depending on the project requirements. Denso specifies the product for girth welds, tie-ins, fittings and rehabilitation of existing pipelines.

Uses and Applications of Denso Protal 7900HT™

Denso Protal 7900HT supports pipeline coating work where the operating temperature requires a high-temperature epoxy system.

• Pipeline girth welds: Workers can apply Protal 7900HT around suitable girth welds to restore external corrosion protection after welding and inspection.
• Pipeline tie-ins: The coating supports tie-in areas where contractors need to protect newly connected pipeline sections.
• Pipeline fittings: Suitable fittings can receive the coating as part of the pipeline corrosion protection system.
• Pipeline rehabilitation: Contractors can use Protal 7900HT during suitable rehabilitation projects involving existing pipelines.
• High-temperature pipelines: The coating suits pipelines that operate at temperatures of up to 120°C.
• Hot pipe coating: Its fast curing characteristics support coating work when contractors apply the product to hot pipeline surfaces.
• Industrial pipeline systems: Suitable pipeline systems in Jubail, Riyadh, Dammam, Jeddah and Al Khobar can use the coating when project conditions match its requirements.

How Denso Protal 7900HT™ Works

Denso Protal 7900HT creates a high-build epoxy barrier over the prepared pipeline surface. The coating separates the substrate from moisture and other environmental exposure that can contribute to corrosion.

The formulation focuses on fast curing and high-temperature service. When contractors apply it to hot pipe within the specified conditions, the coating cures quickly and can help reduce delays before backfilling.

High-Temperature Pipeline Protection

Pipeline systems that operate at elevated temperatures need a coating that can maintain its protective function under those conditions.

Protal 7900HT supports service temperatures of up to 120°C. This makes it suitable for selected high-temperature pipeline applications where a standard pipeline epoxy may not meet the required operating conditions.

Fast Curing on Hot Pipe

One of the main advantages of Denso Protal 7900HT is its fast curing behaviour on hot pipe.

This characteristic can help contractors move through pipeline construction stages more efficiently. The product specifically targets applications where the pipeline operates at elevated temperatures and requires a coating that can cure quickly after application.

High-Build One-Coat Application

Protal 7900HT can achieve up to 1000 µm in one coat. This high-build capability allows contractors to create a substantial protective layer without automatically requiring several coating operations.

For brush application, Denso specifies a minimum thickness of 750 µm and recommends using a wet-film thickness gauge to check the applied coating.

Brush and Spray Application

Workers can apply Denso Protal 7900HT by brush or spray.

Brush application can suit field repairs, weld areas and smaller sections. Spray application can help cover larger pipeline areas efficiently when suitable plural-component equipment is available.

For spray application, Denso specifies a 3:1 volume mixing ratio and controlled product temperatures for Part A and Part B.

Surface Preparation and Application

Proper surface preparation helps Protal 7900HT achieve reliable adhesion and coating performance.

• Grit blast the surface to the specified preparation level.
• Achieve a Sa 2½ / SSPC-SP 10 / NACE No. 2 surface condition.
• Maintain a surface profile of 65–125 µm.
• Remove dust and contamination before coating.
• Preheat the surface where the application procedure requires it.
• Mix Part A and Part B at a 3:1 volume ratio.
• Mix each component individually before combining the components.
• Mix until the material reaches a consistent colour.
• Apply the mixed coating at the specified thickness.
• Use a wet-film thickness gauge during application.
• Allow the coating to cure according to the specified conditions.
• Inspect the completed coating before the next pipeline construction stage.

Cathodic Protection Compatibility

Denso Protal 7900HT can work with cathodic protection systems. This allows the coating to form part of a wider corrosion-control system for suitable pipelines.

The complete coating and cathodic-protection arrangement should match the pipeline design, operating temperature and project requirements.

Storage and Handling

Store Denso Protal 7900HT upright in its original packaging in a cool, dry area.

Denso specifies a recommended storage temperature of 5°C to 35°C. Workers should review the current safety data sheet before handling or applying the coating and follow the required site safety procedures.

Choosing Denso Protal 7900 for Your Application

Before purchasing Denso Protal 7900 in Jubail, consider the pipeline temperature, substrate and application conditions.
