Spiral fin tube use carbon steel or stainless steel strip direct spiral in tube surface for improving heat transfer efficiency.Fin bottom touch tube surface but not bonded together,keep by Tension of the steel belt itself, both end fins can be permanently bonded to the tube by using solder.Cost is low than HFW fin tube.Also named Crimped fin tube.
