How to protect pipes and structures against corrosion with Denso tape

Have you experienced rust or corrosion on pipelines, valves, or steel structures? This is a common problem, especially in humid or demanding environments. Denso Tape is a simple yet highly effective solution for preventing corrosion on steel pipes, fittings, and structures. Here is everything you need to know about the product, how to use it, and why it is a smart choice for your needs.

What is Denso Petrolatum Tape?

Denso Petrolatum Tape is a cold-applied, anti-corrosion protective tape based on a synthetic fabric impregnated with a neutral petrolatum compound. The tape is flexible, moldable, and easy to apply – even on surfaces with light rust or minimal preparation. It is ideal for both underground and above-ground pipelines, valves, flanges, joints, and steel structures.

Why choose Denso Petrolatum Tape?

• Easy application: Can be applied cold, without the need for heat or special tools.
• Surface-friendly: Tolerates light rust and moisture, and can be applied to wet or cold surfaces.
• Long-lasting protection: Provides effective corrosion protection for many years, both below and above ground.
• Flexible and moldable: Can be used on uneven surfaces, pipe bends, and complex structures.
• Cost-effective: Simple to use and requires minimal surface preparation, saving time and money.

How do you use Denso Petrolatum Tape?

1. Prepare the surface

Remove loose rust, dirt, or old coatings. The surface does not need to be perfect, but it should be free of loose particles. For pitted or damaged metal, you can use Denso Paste as a primer.

2. Apply the tape

• Start by wrapping the tape around the pipe or structure with a 50% overlap to ensure full coverage.
  
• Press the tape firmly during application to ensure good contact with the surface.
• For extra protection, especially against UV rays or mechanical wear, you can use an additional protective film such as Denso Ultraseal Tape.

3. Inspection and maintenance

Denso Petrolatum Tape is non-hardening, which means you can easily remove it for inspection. After inspection, you can restore the protection by re-wrapping with extra tape.
