This page is about ASTM A249 TP304 Extruded Single Metal Gombined Metal stainless steel fin tube with fin general material copper / aluminum and we sell these fin tubes in over 70 countries.
Fin tubes are used in many different industries. These tubes have a finned surface, which increases their surface area and allows them to transfer heat more efficiently. Because of that,this makes them ideal for applications where high heat transfer rates are required.And about this fin tube,the fin type is formed from a bi-metallic tube consisting of an aluminium outer tube and an inner tube of almost any material. Besides,the fin is formed by rolling material from the outside of the exterior tube to give an integral fin with excellent heat transfer properties and longevity. Extruded fin offers excellent corrosion protection of the base tube.
Detailes Of ASTM A249Tube
