Tape for pipe insulation

[siricosm]

Does anyone have recommendations for tape to seal the seams in foam pipe insulation? Most tape seems to get brittle over time and lose its stickiness and lets go.

Also does anyone know of a foam pipe wrap? There are a lot of spots around pipe clamps, valves, pumps, etc. that cannot be covered. All I can find online is something that looks like bubblewrap with foil on both sides. It works great, but it is very flammable (found that out soldering one day). Some kind of wrap like that but made with a fire retardant foam would probably work great. Any other suggestions?

To seal seams in foam pipe insulation, try using foil tape or heavy-duty duct tape for better strength. You can also use special insulation tape or PVC electrical tape for moisture protection.

For foam pipe wraps, look for fire-resistant foam wrap or fiberglass insulation for high heat. Mineral wool is another safe choice, and self-adhesive fire-resistant tape can help cover gaps. Always check the product labels to ensure they meet your safety and insulation needs.

Check the manufacturer's specification sheet for the insulation. This will specify the correct tape to use for sealing joints and also the applications it can be used for. For example, insulation for hot pipes is not the same as insulation for cold pipes. Different types are needed for indoor / outdoor / underground duty. And you've already discovered that they differ in fire retardancy.
