Industrial Insulation Elbow

This Unitherm IE0445 jacket insulates a 45-degree pipe elbow in industrial settings. The cover measures four inches by four inches with a three-inch insulation thickness. It fits circumferences between six and thirteen inches. The silicone-coated fiberglass facing resists temperatures up to nine hundred degrees Fahrenheit.

Temperature and Fit Limits

Continuous exposure above nine hundred degrees Fahrenheit exceeds the rated ambient limit. The quick-release flap and wire-twist fastening cannot accommodate circumferences smaller than six inches or larger than thirteen inches. The insulation blend of fiberglass and mineral wool provides an R-value of zero point four eight only within the stated temperature range.

Critical Sizing Parameter

The three-inch wall thickness is the single specification that determines whether this jacket matches the pipe insulation system. A different thickness creates thermal bridging or prevents the flap from sealing correctly. Verify the existing insulation depth before ordering.

Questions about this item

Which thickness of elbow jacket should I choose for a 3-inch wall application?

The 3-inch wall thickness is built into this model, so there is no separate thickness option to select.

What does the R-value of 0.48 mean once the jacket is installed on a hot pipe?

It indicates modest thermal resistance; the jacket will reduce surface temperature and heat loss but is not a high-insulation wrap.

What does the OSHA listing cap in practice for this elbow jacket?

OSHA listing confirms the jacket meets workplace safety requirements for insulated piping; it does not impose a temperature or pressure limit beyond the 900 °F rating.
