Boiler Spare Part H Type Finned Tube For Heat Exchanger for Boiler
Systems
Product Description of H Type Finned Tube
H-type finned tube heat exchanger elements maintain a high capacity
for heat transfer, possess superior self-cleaning properties and
retain the ability to effect flue gas waste heat recovery in boiler
renovations. Convective heat transfer coefficient is proportional
to fin pitch, but inversely proportional to fin height and fin
width. Integrated heat transfer capacity is related to fin
efficiency, convective heat transfer coefficient and finned ratio.
Pressure drop increases with the increase of fin height and fin
width.
Principle of H Type Finned Tube
• 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.
• H-economizer two rectangular fin, similar to a square, its edge
length for the fluorescent tubes of 2-fold, an expansion of the
heating surface.
• H-economizer flash resistance welding processes used, the welding
seam after the high rate of fusion, weld tensile strength, and has
good thermal conductivity. H-economizer can also manufacture dual
tube "double H" type fin tubes, its rigid structure, and can be
applied to a longer tube row occasion.
Detail of H Type Finned Tube
In order to improve the heat exchange efficiency and extend surface
heat transfer, H-type finned tubes have been widely used in boilers
and waste heat recovery in recent years. H-type finned tubes are
derived largely from rectangle finned tubes. Because of their
unique groove structure on the fin surface, H-type finned tubes
have excellent anti-wear and anti-fouling performance.
Structure of H Type Finned Tube
Our products can be modified according to our customers' needs and
the situation.we design and manufacture safe,reliable and efficient
H-fin tubes.HD BOILER has also completed stand-alone product
quality assurance systems.Production of H-fin tubes are with high
heat transfer efficiency, they have flue gas resistance and are
designed for a small space.

Quality Control
1. Impact test and Strength calculation report with applied
materials information.
2. 100%NDT(non-destructive inspection) report of steel plate, tube
and electrode
3. X-ray, γ-ray and liquid penetrant test inspection report
(welding seam): to ensure the quality of the entire boiler
4. Hydraulic test report: ensure the standard working pressure and
safety
