Densyl Tape: Flexible Petrolatum Protection for Pipeline Corrosion Control
Metal pipelines and fittings can remain exposed to moisture, water vapour, gases, salts and other environmental influences throughout their service life. For buried and above-ground pipework alike, maintaining an effective barrier around the metal surface is an important part of corrosion-control practice.
Densyl Tape, from Denso, is a cold-applied petrolatum tape developed specifically for corrosion protection of pipes. Made from durable synthetic-fibre fabric impregnated and coated with a petrolatum compound, it combines flexibility with protective coverage and can follow the contours of different components.
A Protective Layer That Follows the Surface
One of the defining characteristics of Densyl Tape is its conformability. Instead of relying on a rigid coating, the tape can be wrapped around components with different shapes and profiles.
This makes it particularly relevant to:
Buried pipelines
Exposed pipelines
Valves
Pipe fittings
Irregular metal surfaces
The tape is designed for cold application, eliminating the need for a hot-applied installation process.
Built Around a Petrolatum Compound
The construction of Densyl Tape consists of a durable synthetic-fibre fabric that is impregnated and coated with a petrolatum compound.
This combination provides a flexible fabric base together with the protective characteristics required for corrosion-control applications. The material is designed to remain non-hardening and non-cracking while maintaining its ability to conform to the protected surface.
Where Densyl Tape Fits Into a Corrosion-Protection System
Densyl Tape is intended for use on both buried and exposed pipework. It can also be used around valves and fittings, where changes in geometry can make conventional rigid protection more difficult to apply.
Its resistance characteristics include:
Property | Densyl Tape |
Application | Cold applied |
Base construction | Synthetic-fibre fabric |
Protective compound | Petrolatum |
Water resistance | Yes |
Water-vapour resistance | Yes |
Gas resistance | Yes |
Mineral-acid resistance | Yes |
Alkali resistance | Yes |
Salt resistance | Yes |
Hardening | Non-hardening |
Cracking | Non-cracking |
Service temperature | -20°C to +55°C |
These characteristics are specified by BSB for the Densyl Tape product.
Protection in Challenging Environments
Pipeline corrosion can be influenced by the surrounding environment as much as by the metal itself. Moisture, water vapour, gases, mineral acids, alkalis and salts can all create demanding conditions for exposed or buried components.
Densyl Tape is formulated with resistance to these factors, providing a protective wrapping system for metal pipework and associated components.
Application Starts With the Surface
The performance of any corrosion-protection system depends significantly on appropriate surface preparation.
Before Densyl Tape is applied, the surface should be:
Clean
Dry
Free from loose rust
Free from scale
Free from flaking coatings
BSB specifies scraping, wire brushing or blast cleaning as appropriate methods for removing unwanted surface material. Denso Paste or Denso Priming Solution is then applied before wrapping the tape.
This preparation creates the appropriate starting condition for the protective wrapping system.
Temperature Range for Service
Densyl Tape has a stated service temperature range of -20°C to +55°C.
Its ability to remain conformable across a wide temperature range is particularly relevant to pipeline systems that experience changing environmental conditions during service.
A Practical Choice for Pipes, Valves and Fittings
The combination of cold application, surface conformity, environmental resistance and a non-hardening, non-cracking construction makes Densyl Tape suitable for a range of corrosion-protection requirements.
Rather than being limited to straight pipe sections, the tape can be used where the protected component includes valves, fittings or other changes in surface profile.
Densyl Tape Within the Denso Product Range
Densyl Tape forms part of the wider Denso corrosion-protection range supplied by BSB General Trading. The Denso range available through BSB also includes Denso Primer, Densyl Mastic, Denso Paste and Denso PVC Outerwrap.
This wider product family allows different materials to be used as part of a coordinated corrosion-protection approach, depending on the component and application requirements.
Densyl Tape from BSB General Trading
BSB General Trading FZC, based in Sharjah, UAE, supplies Denso anti-corrosion products alongside other industrial solutions. Its Denso range is intended for applications involving pipelines, valves, fittings and other infrastructure requiring corrosion protection.
Conclusion
Densyl Tape is a cold-applied petrolatum corrosion-protection tape designed for pipes, valves and fittings. Its synthetic-fibre construction, resistance to water, water vapour, gases, mineral acids, alkalis and salts, together with its non-hardening and non-cracking characteristics, makes it suitable for demanding corrosion-control applications.
With proper surface preparation and application, Densyl Tape provides a flexible protective wrapping system for both buried and exposed metal pipework, helping form part of a practical Denso corrosion-protection solution.
