Product Details

ASTM A213 Seamless T22 Studded Boiler Fin Tube , Tubo Aletado

Studded 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.

YUHONG Group offers ASTM A213 T22 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.When the flue gas flows through the heat exchange surface of the nail head tube, the smoke-water heat exchange is performed in the heat exchange tube, because the heat exchange surface is increased by the nail head tube, so the heat transfer efficiency is higher.And the surface area of the nail head tube is less ash, which makes the boiler heat transfer performance better and the service life longer.
