Armaflex Class O Pipe Insulation 60mm x 19mm

For 2 inch steel pipe, Armaflex Class O Pipe Insulation 60mm x 19mm fits 60.3mm tube and gives it 19mm of foam cover. It is often used in boiler houses and plant rooms on heating mains, and on cold feeds that need more protection than the light grade offers.

Fitting Armaflex Class O Pipe Insulation 60mm x 19mm

Clean the steel first, because loose scale and old paint flakes stop the foam sitting tight. Run a sharp knife along the tube, open it round the pipe and coat both edges with Armaflex 520 adhesive. Once the glue is touch dry, press the seam shut. Glue the butt joints as well, so warm air cannot reach a cold pipe.

• Bore for 60.3mm (2 inch) steel
• 19mm closed-cell wall
• Fitted diameter about 98mm
• 2 metres long

At around 98mm overall, it needs a bit more space than bare pipe at brackets and through walls. On bends, cut segments and glue them rather than forcing the tube round. Other bores and thicknesses are under pipes, hoses and insulation.

Common Questions

Where would I use 60mm x 19mm Armaflex?

On 2 inch steel heating and water mains that run through cooler voids, undercrofts and plant rooms. It is the middle wall for this size.

How do I insulate a 2 inch gate valve?

Cut separate pieces of tube or sheet to box the valve body in, and glue every joint. Leave the spindle and handle free so the valve can still be worked.

Does this Armaflex come slit?

No, it is plain unslit tube. Slit it yourself with a sharp knife for pipe already in place, and glue the seam.
