Industrial exhaust fume system ducts, white iron ventilation ducts, and spiral ducts are thin-walled pipes made from metal strips coiled into spiral seams. They are circular, weld-free, leak-free for air and water, and are commonly used for air supply and bulk material transportation, replacing traditional white iron pipes (i.e., hand-seamed iron pipes). They are a type of fully mechanized duct, with straight pipes requiring no manual hammering.
