ASTM A213 T5 Alloy Steel Seamless Tube With Al1060 Fin Strip Fin Tube For Air Cooler
ASTM A213 T5 Alloy Steel Seamless Tube With Al1060 Fin Strip Fin Tube For Air Cooler
This product is a high-efficiency finned heat exchanger tube, engineered for use in air-cooled heat exchangers and thermal recovery systems. It integrates a seamless ASTM A213 T5 alloy steel tube with precision-wound or embedded Al1060 aluminum fins, optimizing thermal performance in high-temperature, corrosive environments like power plants, petrochemical plants, and refineries.
Product Overview
-
Base Tube Material: ASTM A213 T5 — a chromium-molybdenum alloy steel with strong creep strength and oxidation resistance at elevated temperatures.
-
Fin Type: Embedded (G-type) or wound (as per requirement).
-
Fin Material: Aluminum Strip Al1060 — highly conductive, lightweight, and corrosion-resistant.
-
Fin Attachment: Mechanical tension winding or embedding ensures secure bonding and excellent thermal contact.
