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.
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.
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.
Typical Chemical Composition (Weight %):
| Element | ASTM A179 Base Tube (Typical) | AISI/ASTM 1060 Fin Material |
|---|---|---|
| Carbon (C) | 0.06 - 0.18% | 0.55 - 0.65% |
| Manganese (Mn) | 0.27 - 0.63% | 0.60 - 0.90% |
| Phosphorus (P) | ≤ 0.035% | ≤ 0.040% |
| Sulfur (S) | ≤ 0.035% | ≤ 0.050% |
Key Mechanical Properties:
| Property | ASTM A179 Base Tube (Requirements) | AISI/ASTM 1060 Fin Material (Annealed Condition) |
|---|---|---|
| Tensile Strength | ≥ 325 MPa (47 ksi) | ≈ 620 MPa (89 ksi) |
| Yield Strength | ≥ 180 MPa (26 ksi) | ≈ 350 MPa (50 ksi) |
| Elongation | ≥ 35% (in 2-inches or 50 mm) | ≈ 15% |
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 .
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.
