Denso Stoneguard in Saudi | Denso Rockshield Supplier in Saudi

Denso™ Stoneguard / Denso™ Rockshield is a heavy-duty protective armouring designed to provide additional mechanical protection for coated metal pipelines installed in rocky ground. Its flexible diagonal mesh construction helps protect the underlying pipe coating from impact, indentation and abrasion caused by rocky backfill. Nassguard supplies Denso Stoneguard in Saudi Arabia, including Riyadh, Dammam, Jubail, Jeddah and Al Khobar.

What Is Denso Stoneguard / Rockshield?

Denso Stoneguard / Rockshield is a flexible outer protection layer for coated metal pipelines. It is mainly used when buried pipelines pass through rocky or abrasive ground where stones and backfill can damage the primary corrosion-protection coating.

The product uses a diagonal mesh construction. This design gives the armouring flexibility during installation while providing strong mechanical protection around the coated pipe.

The open mesh also leaves approximately 70% of the coated pipe surface exposed. This allows electrolyte and cathodic protection current to pass through the mesh and helps avoid cathodic shielding.

Uses and Applications of Denso Stoneguard

Denso Stoneguard / Rockshield is designed for pipeline applications where the primary coating needs extra protection from the surrounding ground.

• Buried pipelines: Provides additional mechanical protection around coated underground pipes.
• Rocky ground: Protects pipeline coatings from sharp and abrasive backfill.
• Pipeline backfilling: Helps protect the coating during and after backfilling operations.
• Rocky trench installations: Provides an additional protective layer where excavated material contains stones.
• Pipeline construction: Supports coating protection during pipeline installation.
• Pipeline rehabilitation: Provides additional protection when suitable coated pipelines require mechanical armouring.
• Long-distance pipelines: Suitable for buried pipeline projects passing through areas with rocky soil.
• Coated steel pipelines: Protects the existing corrosion-protection coating from external mechanical damage.
• Impact protection: Helps reduce damage caused by stones contacting the coated pipe.
• Abrasion protection: Helps protect the underlying coating from abrasive ground movement.
• Cathodic protection systems: The open mesh allows electrolyte and cathodic protection current to pass through.
• Industrial pipeline projects: Suitable projects across Saudi Arabia, Riyadh, Dammam, Jubail, Jeddah and Al Khobar can use the product when the pipeline and ground conditions require additional mechanical protection.

How Denso Stoneguard Works

• Outer armouring: Stoneguard forms a protective outer layer around the coated pipeline.
• Impact protection: The mesh helps absorb and distribute contact from rocky backfill.
• Indentation protection: It helps reduce the risk of sharp stones pressing directly into the primary coating.
• Flexible coverage: The mesh follows the pipe profile and allows easier wrapping.
• Open mesh design: Approximately 70% of the coated pipe surface remains exposed through the mesh.
• Electrolyte passage: The open structure allows electrolyte to move through the armouring.
• Cathodic protection: The design allows cathodic protection current to reach the pipeline surface without creating the same shielding concern as a closed outer layer.
• Coating protection: The primary Denso coating remains protected from direct contact with abrasive backfill.

Protection Against Rocky Backfill

Backfilling can create a significant mechanical risk for buried pipelines. Sharp stones and rocky soil can press against or scrape the primary coating during installation and later ground movement.

Denso Stoneguard provides an additional layer between the coated pipe and the surrounding backfill. This helps protect the underlying coating from impact, indentation and abrasion.

Flexible Diagonal Mesh Construction

The diagonal mesh construction gives Stoneguard the flexibility needed to follow the shape of a pipeline.

Workers can wrap the armouring around the coated pipe without relying on a rigid protective shell. The flexible format also helps simplify installation along long pipeline sections.

Cathodic Protection and Open Mesh

Cathodic protection plays an important role in controlling corrosion on many buried pipelines. An outer protective layer should not unnecessarily block the movement of electrolyte or cathodic protection current.

Denso Stoneguard / Rockshield uses an open mesh design that exposes approximately 70% of the coated pipe surface. This allows uniform electrolyte and cathodic protection current passage through the armouring and helps avoid cathodic shielding.

Denso Stoneguard as an Outer Protection Layer

Denso Stoneguard is used as additional mechanical protection, rather than as the primary corrosion coating itself.

The pipeline should first have the appropriate primary corrosion-protection coating. Stoneguard then provides an outer armouring layer where the installation environment creates a risk of mechanical damage.

This combination can provide a more robust protection system for pipelines installed in rocky or abrasive ground.

Application of Denso Stoneguard

Proper installation helps the armouring provide consistent mechanical protection.

• Inspect the primary pipeline coating before installing the armouring.
• Confirm that the underlying coating has suitable coverage.
• Remove dirt and loose material from the outside of the coated pipe.
• Position the Stoneguard around the coated pipeline.
• Follow the specified wrapping arrangement for the project.
• Keep the armouring in close contact with the coated pipe.
• Maintain consistent coverage along the pipeline.
• Pay attention to transitions, joints and changes in pipe direction.
• Secure the armouring according to the applicable installation procedure.
• Check the finished layer before backfilling.
• Make sure the primary coating remains protected beneath the armouring.
• Complete the backfilling process using the approved project procedure.

Denso Stoneguard for Pipeline Construction

During pipeline construction, coated pipes can encounter stones and other materials when workers lower and backfill the pipeline.

Denso Stoneguard adds an additional mechanical barrier around the coated pipe. This makes it particularly useful when the pipeline route contains rocky soil or abrasive backfill.

The additional armouring helps protect the primary coating during the installation and backfilling stages.

Denso Stoneguard for Pipeline Rehabilitation

Existing buried pipelines may require additional mechanical protection when workers expose, repair or rehabilitate sections of the line.

After suitable coating repair and inspection, Denso Stoneguard can provide an additional protective layer where the surrounding ground creates a risk of mechanical damage.

The selected protection system should match the existing pipeline coating and project requirements.

Choosing Denso Stoneguard for Your Application

Before purchasing Denso Stoneguard in Saudi Arabia, consider the pipeline and surrounding ground conditions.

• Identify the pipeline coating that requires additional protection.
• Check whether the pipeline passes through rocky or abrasive ground.
• Assess the risk of impact and indentation from backfill.
• Consider the amount and type of rock around the pipeline.
• Inspect the existing primary coating.
• Confirm the required outer protection system.
• Consider the cathodic protection arrangement.
• Check the required wrapping method.
• Plan the installation before backfilling.
• Inspect the completed armouring before covering the pipeline.
• Follow the applicable project installation requirements.

Storage and Handling

Store Denso Stoneguard / Rockshield in suitable conditions and protect the material from excessive moisture, contamination and physical damage before installation.

Handle the mesh carefully to prevent unnecessary deformation or damage. Workers should use appropriate PPE during handling, wrapping and pipeline installation work.
