RPR Products Insul-Mate™ Aluminum Jacketing is manufactured from wrought aluminum alloy 3003 or 3105 meeting ASTM standard B209 with an H-14 temper. The properties of these aluminum alloys provide the required strength to resist in-service abuse, but can be easily fabricated and installed. The attractive mill finish maintains its sharp appearance, a necessity for any insulation project. Aluminum’s resistance to atmospheric corrosion makes its use ideal, even in marine, chemical, industrial environments, or in industries processing food or beverages. Aluminum has an excellent resistance to corrosion which reduces cost through long service, without maintenance or painting. •RPR fabricates aluminum jacketing into precut – cut and rolled or flat cut pieces. Pieces are cut to accommodate various pipe and insulation sizes. They are produced to ASTM standards for industrial or commercial applications.
