ASME SA179 G Type Embedded Finned Tube With Aluminium Fin For Air Cooler
What are finned tubes used for?
Finned tubes are the main components of heat exchangers. They are a series of tubes where fins have been added on the outside to increase the contact area with the outside fluid, to exchange heat and between the fluid inside the tube and the fluid outside the tube. Finned tubes are elongated aluminium cladded carbon steel flat tubes with brazed aluminium fins.
G Type Embedded Finned Tube is combined with two different materials
Core tube material: carbon steel, low alloy steel, stainless steel, brass, copper, copper-nickel alloy, aluminum bronze, nickel alloy.
1. Carbon steel: A179, A192, SA210 Gr A1/C, A106 Gr B
2. Stainless steel: TP304/304L, TP316/TP316L/316Ti, A789 S31803/S2205
3. Copper: UNS12200/UNS14200/UNS70600, CuNi70/30, CuNi 90/10
