HH Square Fin Tube Thickness 65mm Rectangular Plate

H/HH Fin Tube Square Rectangular Fin Tube Plate Finned Tube​

In order to improve the boiler efficiency, the outer surface area (or inner surface area) of the boiler tube is generally increased by adding H fins on the surface of the boiler tube, thereby achieving the purpose of improving boiler efficiency.

H fin tube known as square fin tube, There are two type of H fin tubes, one type with single tube, normal called square fin tube, the other with Double tube, normal called rectangular fin tubes. and also manufactured as per customers requirements. Due to rectangular shapes, which can offer large surface area compared to the Spiral Finned tubes. Due to larger surface area available, these finned tubes are used mostly in Air Heating application to reduce the overall size of the equipment.

H fin tube is a kind of boiler parts, to have two steel circular symmetry to be welded on fluorescent tubes to form fins positive shap much like letter "H", so called H-fin tube. H-economizer widely used in utility boilers, industrial boilers, marine power, such as the tail of heat exchanger components.
