Overview
ASTM A249 TP304 is a specification for stainless steel fin tubes. It covers welded tubes made from austenitic stainless steel grade TP304. Fin tubes are used in various applications, including heat exchangers, boilers, and condensers. ASTM A249 TP304 specifies the requirements for dimensions, mechanical properties, and surface conditions of the fin tubes. It's important to follow the specifications for ensuring the proper performance and quality of the stainless steel fin tubes.
Types of Fin Tubes
1.Extruded Fin Tubes: These finned tubes have fins that are formed by extruding the material of the tube itself. The fins are typically integral and inseparable from the base tube.
2.Embedded Fin Tubes: Embedded fin tubes have fins that are embedded or inserted into grooves on the outer surface of the base tube. This design provides strong fin-to-tube bonding and is suitable for high-temperature applications.
3.Wound Fin Tubes:L/LL/KL fin tubes feature fins that are wrapped around the base tube in a specific pattern. They are often used in air-cooling applications and provide a larger surface area for heat exchange.Waste Heat Recovery
