How DensoClad™ Tape Works

DensoClad Tape combines a bitumen adhesive with a tough PVC backing. The adhesive bonds to the prepared and primed surface, while the PVC backing provides mechanical protection.

Workers wrap the tape around the pipe in a spiral pattern. The overlapping layers create continuous coverage across the protected area.

The PVC backing helps protect the coating during handling, installation and backfilling, while the bitumen layer helps prevent moisture and corrosive elements from reaching the steel.

Heavy-Duty Protection for Buried Pipelines

Buried pipelines can face soil stress, moisture and mechanical contact during installation and backfilling.

Densoclad 70 provides a heavier-duty option for medium and large diameter pipelines. Its tough PVC backing helps protect the coating from damage during handling and backfilling.

For heavy soil conditions, the correct Densoclad grade can provide additional protection against mechanical stress.

DensoClad™ for Welded Joints and Bends

Pipeline welded joints and bends need continuous external corrosion protection.

Workers can apply DensoClad Tape around suitable welded joints and bends after completing surface preparation and priming. Its conformable backing helps the tape follow curved pipeline sections.

The correct wrapping technique helps maintain continuous protection across the entire joint or bend.

Hand and Machine Application

DensoClad Tapes support both hand wrapping and machine application.

Hand application can suit smaller pipe sections, repairs and areas where machinery cannot reach easily. Machine wrapping can help improve consistency and productivity on longer pipeline sections.

The selected application method should match the pipe diameter, tape grade and project requirements.

DensoClad™ and Denso Primer D™

Denso Primer D™ is the recommended primer for DensoClad Tapes. Workers apply the primer across the area that will receive the tape.

The primer helps prepare the surface for the bitumen adhesive layer. Workers should allow the primer to dry to the required condition before starting the wrapping process.

DensoClad™ Tape Wrapping

Correct overlap plays an important role in creating continuous pipeline protection.

Workers should wrap the tape spirally with a 55% overlap. They should maintain consistent tension and press the tape firmly against the prepared surface.

The finished wrapping should cover the complete area without gaps, exposed steel or loose sections.

Surface Preparation and Application

Proper surface preparation helps DensoClad Tape achieve reliable adhesion.

• Clean the pipe surface before starting the wrapping process.
• Remove grease, dirt and other contamination.
• Remove loose rust, scale and flaking coatings.
• Use wire brushing to ISO 8501-1 St 3 where specified.
• Use abrasive blast cleaning to ISO 8501-1 Sa 2½ where required.
• Apply Denso Primer D™ over the area that will receive the tape.
• Allow the primer to dry until touch dry.
• Start wrapping the tape over the prepared surface.
• Wrap the tape spirally with 55% overlap.
• Maintain consistent wrapping tension.
• Smooth the tape onto the pipe as you work.
• Avoid gaps and exposed sections.
• Check the completed wrapping before backfilling or immersion.
• Add the required additional protection when the project specification calls for it.

DensoClad™ for Heavy Soil Conditions

Heavy soil can place additional stress on buried pipeline coatings. Sharp materials and movement during backfilling can also damage the external protection.

Densoclad 70 provides a heavy-duty option for these conditions. Its tough PVC backing gives the wrapped system additional mechanical protection.

This makes the grade suitable for selected medium and large diameter pipelines where the risk of soil stress or damage is higher.

High-Temperature DensoClad™ Tapes

The DensoClad range includes HT grades for applications that require higher service temperatures.

Examples include Densoclad 40HT, 41HT, 50HT, 55HT and 70HT. The correct grade depends on the pipe size, mechanical protection requirement and operating temperature.

For example, Densoclad 70HT has a stated service temperature of -20°C to +75°C.

Water, Soil and Chemical Resistance

DensoClad Tape provides resistance to water, water vapour and gases. The bitumen compound also resists acids, alkalis and salts.

This makes the system suitable for selected buried and immersed pipeline environments where the external coating must withstand moisture and soil exposure.

Inspection and Maintenance

Inspect the wrapped pipeline before backfilling or placing the asset into service.

Workers should check the tape for gaps, loose sections, exposed metal, damaged areas and poor overlaps. Any visible defect should be repaired before the pipeline moves to the next stage.

Regular inspection can help identify coating damage early and reduce the risk of corrosion reaching the steel surface.

Choosing the Right DensoClad™ Tape

Before purchasing DensoClad Tape in Saudi Arabia, consider the pipe size, environment and mechanical protection requirement.

• Identify the pipe diameter.
• Check whether the pipeline will remain buried or immersed.
• Assess the soil conditions.
• Check the risk of mechanical damage.
