What kind of spiral pipe is used for ductwork?
Single Wall Spiral Pipe for Commercial and Industrial HVAC Ductwork. Sheet Metal Connectors, Inc. spiral pipe is formed from a coil of metal into a rigid steel tube with a 4-ply spiral lockseam. It has smooth interior for low friction loss with the grooved seam entirely on the outside.
Do you have spiral ducts in your HVAC system?
Most of the time, for a typical HVAC system, they indicate you want spiral duct. But for some reason, we often see engineers leaving these symbols off of their drawings. Perhaps they can’t find them in their CAD libraries. But when you leave them off, you are usually going to end up with poor-performing and costly rectangular duct.
What size spiral pipe do I need for dust collection?
