Low Alloy Steel Embedded G Type Fin Tubes ASTM A213 T5 In Air Cooled Heat Exchanger

Embedded G Fin Tube,ASTM A213 T5 Low Alloy steel Tube,Air Cooled Heat Exchanger

An embedded G fin tube, also known as a G-type fin tube, is a specialized heat transfer component designed for enhanced thermal performance. It features aluminum or copper fins that are mechanically embedded into a groove on the outer surface of a metal base tube.

The manufacturing process involves the following steps:

• A helical groove is plowed into the base tube.
• The fin strip is wound into the groove under tension.
• The groove is then backfilled with the base tube material to secure the fin in place.
• The fin is locked into position by rolling the groove closed.

What is key charateristic of embedded G Fin Tube?

• High Thermal Performance: The embedded design ensures excellent heat transfer efficiency, even at high operating temperatures up to 400°C.
• Durability: The mechanical bond between the fin and the tube provides high stability and resistance to thermal cycling.
• Cost-Effective: Compared to extruded fin tubes, G fin tubes offer a good balance between performance and cost
• Material Options: The core tube can be made from carbon steel, stainless steel, copper, or other alloys, while the fins are typically made from aluminum or coppe.

Embedded G fin tubes are widely used in various industries, including:

• Air-cooled heat exchangers in power plants and refineries.
• ​HVAC systems, refrigeration, and air conditioning.
• Waste heat recovery systems.
• Process heating and cooling in chemical and petrochemical industries.

Advantages:

• High fin stability and excellent heat transfer performance
• Suitable for high-temperature applications
• The fin remains firmly attached even under mechanical stress

​Limitations:

• Mechanical strength of the fins is relatively low, making them susceptible to damage from external forces.
• Care must be taken during handling and cleaning to avoid damaging the fins.

ASTM A213 Mechanical Properties

General Requirements

• Scope: ASTM A213 covers seamless tubes made from various ferritic and austenitic alloy steels, designed for high-temperature and high-pressure applications.
• Size Range: Tubes are typically available in sizes ranging from an outside diameter of 1/8 inch (3.2 mm) to 5 inches (127 mm) and wall thicknesses from 0.015 inch (0.4 mm) to 0.500 inch (12.7 mm).
• Additional Notes
• Heat Treatment: Many grades require specific heat treatment processes to achieve the desired mechanical properties. For example, T23 is often supplied in the quenched and tempered condition.
• Impact Resistance: Some grades, like T23, exhibit high impact resistance, with a typical impact energy of 42 J.
• Elongation Adjustments: For certain grades, the minimum elongation values may be adjusted based on wall thickness.
• Hardness Testing: Hardness tests are often performed to ensure the material meets the specified mechanical requirements.​
