ASTM A106 Seamless Carbon Steel Square (H Type) Fin Tube For Radiator

ASTM A106 Seamless Carbon Steel Square (H Type) Fin Tube for Radiator is a high-efficiency heat transfer component designed for industrial heating systems. Manufactured from ASTM A106 Gr.B seamless carbon steel pipe, it features a square base tube with helically welded H-type fins to maximize heat dissipation. This fin tube is engineered for high thermal conductivity, pressure resistance (suitable for high-temperature steam/water systems), and long-term corrosion protection, making it ideal for radiators, heat exchangers, and boiler applications. Its optimized fin geometry (H-Type) ensures enhanced airflow and heat transfer efficiency in confined spaces, reducing energy consumption while maintaining structural durability under harsh operating conditions.

1.H-type Fin Tube Related Overview

• The fin is divided into two symmetrical half pieces. The tube wall is pressed down from both sides, and resistance welding is used to weld on the pipe wall with a certain gap left in the middle;

• Two circular tubes can share a group of fins, called double tube H-shaped fins, or a single tube H-shaped fin can be placed in the middle;

• The heat exchanger composed of H-type finned tubes is closely arranged and the tube bundles are arranged in order;

• The fins are parallel and independent of each other, and there is no influence of helix angle, so it is easy to remove ash.

3. Key Features

• Innovative H-type double-fin structure increases heat transfer area by 40% compared to round fins, while significantly reducing fouling risk.
• ASTM A106 carbon steel has good thermal conductivity and high heat exchange efficiency, which helps the radiator cool down quickly. Seamless steel pipe base material, no weld defects, good deformation and vibration resistance, long-term reliable operation.

• High-Frequency Welded Fins: Secure bonding (shear strength ≥35 MPa) with no risk of detachment.

• With a reasonable carbon steel composition and surface treatment (if any), it can resist a certain degree of oxidation and corrosion in conventional heat dissipation environments (such as heating systems, industrial cooling, etc.), prolonging the service life.
