Aluminum Roll Jacketing is the premier protective outer surface for mechanical insulation systems including pipe, vessels, and equipment. It protects the insulation and underlying pipes/vessels from physical damage, UV exposure, corrosive atmospheres, and water.
Aluminum Roll Jacketing has a bare outer surface and comes Polykraft moisture barrier heat-laminated to the interior surface to help prevent corrosion of the jacketing and the underlying metal pipe, vessel, or equipment
Moisture barrier is a coating applied on the underside of the Metal Jacketing to prevent corrosion of the jacket and pipe. It is a very important component of a good insulation system and used in all applications including hot and cold applications. The purpose of the barrier is to isolate the jacket from other insulation layers and shield the underside of the metal jacket from moisture contact to prevent corrosion.
Poly Kraft is a layer of Kraft paper laminated to a thin layer of polyethylene film which is factory applied on the metal in a lamination process. It is an improvement from the paint system and uses polyethylene layer which is good for moisture resistance.
Aluminum Roll Jacketing is produced from 3003 or 3105 or 1050 Series Aluminum, conforming to ASTM B-209 and ASTM C1729. Jacketing is available with either of the following moisture protection membranes: Poly Kraft (Kraft & Polyethylene)
Both Polysurlyn and Poly Kraft membranes are heat and pressure bonded to the interior surface of the jacketing.
Flat aluminum sheets are often coils of 1000 to 2000 meters and with a width of 1 m or in the form of a 2 × 1-meter sheet and with thicknesses of 0.4 to 1.2 mm is presented.
The above sheets are often used to cover Pipes, Elbows, Spherical Surfaces and tanks as well as aluminum boxes.
