Product Information

Full details

The AF/Armaflex Evo Nitrile Pipe Insulation is an ideal solution for professionals and homeowners seeking to optimize thermal efficiency and prevent condensation in hot and cold water services, refrigeration, and chilled water lines. Its highly flexible, closed-cell elastomeric foam structure provides robust protection against moisture-related corrosion, though the material requires precise sizing to ensure a tight fit for maximum vapor resistance.

Extended Product Information

FAQs

Is this product suitable for outdoor use?

It is primarily designed for indoor use. If used outdoors, it must be protected with appropriate UV-resistant cladding or paint.

Can it be used on steam pipes?

This insulation is rated for specific temperature ranges; check the technical specifications for your specific steam temperature to ensure it does not exceed the material limits.

Does it contain any hazardous fibers?

No, AF/Armaflex Evo is completely dust and fibre-free, making it safe to handle.

How do I join two pieces of insulation?

Use Armaflex adhesive on the butt joints to ensure a continuous thermal and vapour barrier.

Does it prevent pipe freezing?

While it significantly delays freezing by slowing heat loss, it is not a heating device and cannot prevent freezing indefinitely in extreme cold.

Troubleshooting

Condensation forming on the outside of the insulation

Ensure all joints are sealed completely with compatible adhesive and check that the insulation thickness is appropriate for the pipe temperature.

Difficult to slide over pipe

Apply a small amount of talc or ensure the internal diameter is correctly matched to the outer diameter of the pipe. Avoid forcing it, which can tear the foam.

Pros and Cons

Pros

  • High resistance to water vapour diffusion
  • Provides both thermal and acoustic insulation
  • Easy to install due to flexible construction
  • Safe for use in environments where air quality is critical
  • Durable against microbial growth

Cons

  • Requires exact pipe sizing for optimal fit
  • Does not feature a self-adhesive seam
  • May require extra sealing at joints to maintain vapor integrity

Setup, Compatibility & Care

To install, slide the tubular insulation onto the pipe before soldering or connecting fittings. For pre-installed pipes, the foam can be slit longitudinally, placed around the pipe, and secured with appropriate Armaflex adhesive to ensure the seams remain airtight. Ensure the pipe surface is clean and dry before application. To maintain the insulation, periodically inspect the joints to ensure the protective seal is intact. If the material is exposed to direct UV rays, it should be coated with a protective paint or cladding to prevent long-term degradation of the elastomer structure.
