Armaflex Class O Pipe Insulation 76mm x 13mm

Armaflex Class O Pipe Insulation 76mm x 13mm is a 13mm wall tube for 76.1mm pipe, so it covers both 76mm copper and 2 1/2 inch steel. The light wall suits heating mains inside warm buildings, where the job is to stop heat leaking out on the way.

Armaflex Class O Pipe Insulation 76mm x 13mm on large mains

76.1mm is a big main, found in commercial boiler houses and on distribution in larger buildings. A bare main of that size heats up a plant room quickly. A 13mm wall of closed-cell foam cuts that loss and keeps the finished size manageable on crowded brackets.

• Fits 76mm copper or 2 1/2 inch steel
• 13mm wall
• About 102mm overall when fitted
• 2 metre lengths

On steel, brush off loose rust first. Cut the tube down one side, fit it on and stick the seam with Armaflex 520 glue. Glue the ends where lengths meet, and build up covers for valves and flanges from offcuts. If part of the run passes somewhere cold, use a thicker wall there.

Common Questions

What pipe does 76mm Armaflex fit?

It is sized for 76.1 outside pipe, which covers 2 1/2 inch steel and large copper. Check the pipe outside size before ordering.

Is 13mm wall suitable on large heating mains?

Inside a warm building, the 13mm wall cuts heat loss without taking much space. Use thicker walls where the main crosses cold areas.

How many lengths for 10m of 76mm pipe?

Five 2m lengths. Buy extra for flanges and valves.
