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.
