Carbon Steel ASTM A179 A1060 G Type Embedded Fin Tube - For Heat Exchangers & Condensers

Product Overview & Specification

This product is a high-efficiency Embedded G-Type Fin Tube designed for demanding heat transfer applications. It combines the excellent thermal conductivity and formability of a seamless low-carbon steel base tube with the superior strength and wear resistance of high-carbon steel fins.

The core tube is manufactured in strict compliance with ASTM A179/A179M, the standard specification for seamless cold-drawn low-carbon steel tubes used in heat exchangers and condensers . The fins are made from AISI/ASTM 1060 high-carbon steel. The "G-Type" or embedded fin design typically involves a fin strip wound into a machined helical groove on the base tube and secured by the raised metal, ensuring a permanent, metallurgical bond with outstanding heat transfer efficiency and mechanical durability.

Material & Structure

This is a composite product utilizing two distinct steel grades for optimal performance:

• Base Tube: Made from ASTM A179 seamless cold-drawn steel. This material is chosen for its consistent quality, good ductility, and excellent thermal conductivity, making it ideal for the pressure-containing component of a heat transfer tube .

• Fins (Embedded): Made from AISI 1060 (ASTM A1060) high-carbon steel. This grade is selected for applications requiring higher strength, hardness, and wear resistance than lower-carbon steels can provide . The high carbon content gives the fins robustness in harsh operating environments.

Chemical Composition & Mechanical Properties

The following tables summarize the key specifications for the constituent materials. Note that ASTM A179 is a product standard for tubes, while A1060 refers to a material grade.

Key Mechanical Properties:

The final finned tube product undergoes multiple quality tests as per standards, which may include hydrostatic testing, flattening tests, flaring tests, and hardness tests to ensure integrity .

Primary Applications

This fin tube is engineered for heavy-duty heat exchange equipment where efficiency and durability are critical:

• Fired Heaters & Boilers: As economizer or convection section tubes.

• Air Preheaters & Process Heat Exchangers in chemical and petrochemical plants.

• Waste Heat Recovery Units where flue gas may contain abrasive particulates.

• Condensers and other heat transfer apparatus in power generation and industrial settings .

• Applications requiring enhanced wear resistance on the finned surface due to high-velocity or particulate-laden fluids.
