ASME SA179 G Type Embedded Finned Tube with Aluminum Fins For Air Cooler
ASME SA179 G Type Embedded Finned Tube with Aluminum Fins is a high-efficiency heat transfer component: it uses an ASME SA179 low‑carbon steel base tube with aluminum fins mechanically embedded into spiral grooves on the tube’s outer surface. It is widely used in heat exchangers, condensers, air coolers, and HVAC systems.
