Fiberglass Pipe Insulation for Industrial Applications

Cutting fiberglass pipe insulation tubes to the desired length is quite simple. By using a mitre box, professionals can cut the insulation and its jacket at 30°, 45°  and  90° angles. Then, using a dull knife, a cut can be made. At this point, the fiberglass pipe insulation is ready to be installed by simply pulling the tube lengthwise and pushing it over the pipe.

Fiberglass pipe insulation can be installed on exhaust pipes, though with caution. Basic fiberglass insulation has a risk of melting when being exposed to hot temperatures. That said, ASJ Max Fiberglass Insulation has a max operating temperature rating of 1,000°F. Most exhaust pipes rarely reach or exceed this temperature, making this type of insulation appropriate. However, it should be noted that the paper jacket of fiberglass insulation is flammable so these should be kept away from any industrial operations that include an open flame.

Yes, fiberglass insulation does hold water from water pipes. Fiberglass pipe insulation runs a very low risk of holding water from pipes, but in the event of a leak, flood, or maintenance in which it gets wet, this could be a problem. 

When used as intended, fiberglass pipe insulation with an encapsulated paper jacket does not support mold or mildew growth. It also resists water when exposed to intermittent, short-term precipitation — such as condensation or during construction.

The most common type of insulation fiberglass is mineral wool — which, like fiberglass, offers its own unique properties. Mineral wool is often better for more extreme hot temperature insulation, though it is much denser than fiberglass, making it heavier. Fiberglass is much more manageable for hanging or elevated pipe systems that require insulation. Fiberglass pipe insulation is typically made of 20 to 30 percent recycled material while mineral wool insulation is often made of 70 percent recycled content, making it a more sustainable option.

Fiberglass pipe insulation is popular in nearly every industrial sector. From solar and alternative energy to manufacturing and refining, fiberglass insulation offers a reliable alternative to other types of insulation. The only industrial applications that this type of insulation is not suitable for involve open flames or extremely high temperatures that may melt the fiberglass or ignite the paper jacket.

When you should replace insulation wraps depends greatly on the application of the insulation. A lot of it has to do with how hot the ducts are, and if there is any moisture in the area. Having your insulation infrastructure inspected by a professional every five to ten years will help you keep an eye on it and let you know when it is ready to be replaced.
