ASTM A213 Seamless T9 Studed Fin Tube For Boiler , Radiador
A studded fin tube refers to a type of heat exchanger tube that has metal studs or fins attached to its outer surface. The purpose of studded fins is to increase the surface area of the tube, which in turn enhances heat transfer efficiency.
Studed Tubes are applied to convection chamber of heating furnace in petrochemical industry to increase the heat transfer coefficient at the fuming side. Studded Tubes are two or three times the square of light Tubes and due to the usage of studded Tubes, the hot strength can be obtained as the same as radiation in the reasonable design.
This design is often used in applications where maximum heat transfer is required, such as in boilers, air conditioning systems, and industrial processes. Studded fin tubes are commonly made from materials like carbon steel, stainless steel, or aluminum.
YUHONG Group offers ASTM A213 T9 welding studed alloy steel fin tube and we sell this type of fin tubes in over 70 countries.It has excellent enhanced heat creation effect, reduces heat transfer resistance, and improves heat transfer coefficient.
