Unitherm FPW1224 2in x 12in Insulated Pipe Jacket 3in Wall

Unitherm FPW1224 Insulated Pipe Jacket

This Unitherm FPW1224 insulated pipe jacket is designed for industrial maintenance teams and facility engineers who need reliable thermal protection on straight pipe sections and tee or wye fittings. The mineral wool insulation with a silicone facing withstands ambient temperatures up to 200 degrees F. A lacing anchor and wire fastening system secures the cover around circumferences up to 6 inches. It meets OSHA Safe-Touch standards for workplace safety.

Replaces damaged or missing flange jackets

The jacket covers a 12-inch length with a 24-inch width and 3-inch thickness, making it a direct fit for existing installations using the same dimensions. Upgrading is worthwhile when the original cover has degraded, when surface temperatures exceed safe-touch limits, or when an R-value of 0.48 improves energy retention on the line. The 18 AWG cable gauge supports the 120V operating voltage required for integrated heating trace systems.

Mineral wool and silicone construction limits

The insulation material and facing determine the maximum 200-degree F service temperature; higher process heat requires a different jacket specification. The R-value of 0.48 reflects the 3-inch thickness provided, so greater thermal resistance demands a thicker or alternative insulation system. The lacing anchor closure sets a practical maximum circumference of 6 inches; larger pipes or fittings will not close securely with this cover.
