The chemical inertness of PVS combined with the strength of Spiral pipe make Vinyl Coated Duct ideal for chemical fume removal applications and for underground HVAC applications where strength and resistance to corrosive salts and other minerals found in backfill are prerequisites. Our vinyl-coated Spiral pipe is UL listed and manufactured from galvanized steel coated with a polyvinyl chloride material with an outside thickness of 4 mils and inside thickness of 1 mil standard. This is reversible for special purposes. External corrugations are standard for over 14" diameter for underground applications. Standard gauges are: 4" to 16"/24 gauge, 17" to 24"/22 gauge, 26" to 48"/20 gauge. Standard Lengths 5 and 10 foot.
Economical to install–the unique attributes of Spiral duct can reduce installation costs:
Lower cost of ownership – Spiral duct reduces upfront and operating costs:
- Low air leakage, optimal airflow characteristics, and less pressure drop allow smaller and more efficient air moving equipment
- Inherently stronger, allowing the use of lighter gauge, less costly metals
- Efficiently manufactured from strip steel to any diameter
- Spiral duct's smooth interior traps less dust and is easier to clean
