The ASTM A249 TP304 stainless steel L-fin tube is a welded austenitic stainless steel tube wrapped with helically wound L-type fins, typically made from aluminum or stainless steel. The L-shaped fin is tightly wound under tension to ensure close metal-to-metal contact, which improves heat transfer performance.
