AAC’s stainless steel roll jacketing is manufactured from Stainless steel Type 304 and 316 prime grade austenitic stainless steel with a regular 2B mill finish for flatness and reduced glare.
AAC’s stainless steel roll jacketing is manufactured from Stainless steel Type 304 and 316 prime grade austenitic stainless steel with a regular 2B mill finish for flatness and reduced glare. The yield strength is 30,000 PSI and the tensile strength is 75,000 PSI. For easy field fabrication, AAC offers stainless steel jacketing in the annealed or soft condition. AAC’s 304 and 316 stainless steel jacketing adhere to the ASTM A240 and A666 standards. AAC’s stainless steel jacketing has a melting point of approximately 2500? F. Stainless steel offers the best fire protection of all metals.
AAC offers Stainless Steel grades in various thickness ranging from in thickness of 0.25–1.5mm. Standard widths available are 914mm, 1000mm, 1219mm, while other widths are also available on special orders for which minimums may apply.
Types of Moisture barrier :
Polysurlyn Moisture Barrier (PSMB) is an engineered three layer coextruded film of polyethylene and DuPont™ Surlyn® polymers with a total film thickness of 3 mils (76 μm).PSMB is heat laminated in the factory to the interior surface of all types of metal jacketing for mechanical insulation to help prevent pitting, crevice, and galvanic corrosion of the interior surface of the metal jacketing and the underlying
insulated pipe, tank, or equipment. Conforms to BS 476 : Part 7 : 1997 Surface Spread of Flame Class 1
Polykraft consists of one layer of one mil polyethylene film with a protective layer of 40# virgin kraft paper.The moisture barrier is factory applied by attaching the jacketing by continuous lamination to the full width of the metal. The moisture barrier is used to prevent moisture and corrosives in the insulation from coming into direct contact with the metal jacketing surface and causing galvanic or chemical corrosion.
