ASTM A179 Carbon Steel Embedded Fin Tube for HRSG Systems

Carbon Steel Fin Tube, ASTM A179, Embedded Fin Tube, For HRSG System

Product Introduction

The ASTM A179 Carbon Steel Embedded Fin Tube is a specialized heat transfer component used in Heat Recovery Steam Generator (HRSG) systems. It features aluminum or carbon steel fins mechanically embedded into the grooved carbon steel base tube. This design ensures excellent thermal contact and mechanical bonding between the fin and tube, providing efficient and durable heat exchange in high-temperature gas paths typical in HRSG applications.

Chemical Composition – ASTM A179

Mechanical Properties

Key Advantages

• High Heat Transfer Efficiency
  The embedded fin design provides a larger surface area and strong thermal contact, optimizing heat recovery from flue gases.

• Strong Mechanical Bonding
  Fins are embedded into the base tube using a mechanical rolling process, ensuring long-term durability even under vibration and thermal cycling.

• Cost-Effective Option
  Carbon steel offers an economical solution for non-corrosive, dry flue gas environments in HRSG systems.

• Easy to Fabricate & Replace
  ASTM A179 material is easy to bend, cut, and weld, allowing for custom configurations and efficient maintenance.

Applications

Used in HRSG systems as:

• Economizer Tubes

• Evaporator Coils

• Preheater Tubes

• Heat Recovery Coils

Position: Installed in the flue gas path of gas turbines or boilers, recovering waste heat to produce steam for combined cycle power plants or process applications.
