A helical wire core is a flexible structural component made of coiled wire that provides shape retention and support in flexible ducts, maintaining airflow while allowing bending.
The helical wire core is a critical structural element in flexible duct systems, consisting of a continuous steel wire formed into a precise helical coil. This component provides radial strength to prevent duct collapse under negative pressure while maintaining flexibility for installation around obstacles. The wire's pitch, diameter, and material properties determine the duct's minimum bend radius, pressure rating, and durability. In HVAC applications, it ensures consistent airflow by maintaining cross-sectional area during bending and compression.

The minimum bend radius is determined by wire diameter, coil pitch, and material elasticity. Thicker wires with tighter pitches allow smaller bend radii without permanent deformation.
Localized damage can sometimes be repaired with specialized wire splicing, but extensive damage typically requires complete duct replacement to maintain pressure integrity.
Galvanization provides corrosion resistance for standard applications, while polymer coatings reduce friction and noise. Stainless steel offers superior corrosion resistance for harsh environments.
