Permaloy™ Abrasion Resistant Pipe is alloyed centrifugally cast Ductile iron pipe, offering superior abrasion resistance for hydraulic or pneumatic conveyance of fly and bottom ash, mine tailings, sewage, and other abrasive materials.
Permaloy I is a tin, copper, and chrome alloyed pipe possessing a minimum Brinell hardness of 280 at the inside diameter and approximately 400 at the outside diameter.
Permaloy II is a nickel, molybdenum, and chrome alloyed pipe possessing a minimum Brinell hardness of 475 at the inside diameter and approximately 550 at the outside diameter. Permaloy I and II pipe’s design characteristics produce a thick-walled product possessing a high Brinell hardness inside diameter, which grows progressively harder toward the outer diameter. This characteristic results in the product continuously becoming resistant to wear the longer it is in service.
