ASME High Frequency Welding H Type Extruded Fin Tube For Heat Exchanger
H-fin Tubes have two steel discs,with fluorescent tubes symmetrically welded together to form fins(fins of butterfly piece)creating a shape that looks somewhat like the letter"H",creating an efficient energy saving, extension heating surface.H-fin Tubes also have a high rate of fusion welds and weld tensile strength.H-fin Tube is assembled with the H economizer, which has high efficiency,little resistance,less wear and light weight.
H finned tube is called square finned tube, there are two types of
H finned tube, one is a single tube, usually called square finned
tube, the other is a double tube, usually called rectangular finned tube.
And according to customer requirements manufacturing. Due to its rectangular shape, it provides a larger surface area
than spiral finned tubes. Because of the larger surface area
available, these finned tubes are primarily used in air heating applications
to reduce the overall size of the equipment.
H-type tube, has a high rate of fusion welds and weld tensile strength. There is little contact resistance, and heat transfer performance and scalability are additional advantages. The H-fin tube is assembled with the H economizer, which has high efficiency, low resistance, and light weight. Compared to the traditional fin tube or spiral tube the H-fin tube can greatly expand the heating surface. When the extent of the effect of heat transfer is the same. The H-fin tube economizer takes up less space. In addition to the H economizer, H superheater, H air heater, and many other products. The H-fin tube has been included in the “Chinese high-tech product catalog”

Product Description
1.Finned Tube Heat Exchangers consist of a shell and finned tubes
assembly.
2.Fins are used to increase the effective surface area of heat
exchanger tubing.
3.Finned tubes are used when the heat transfer coefficient on the
outside of the tubes is appreciably lower than that on the
inside;as in heat transfer from a liquid to a gas,vapor to a gas
,such as steam to air heat exchanger, thermic fluid to air heat
exchanger, when an extended surface is needed on only one fluid
side or when the operating pressure needs to be contained on one
fluid side.
Fin tube heat transfer area is 8 times than the light tube, high
efficiency heat exchange, more advanced than the other heat
exchange products.
Application: Boiler Economizer, Heat Exchange, Power Plant Waste
Heat Boiler,Petrochemical Engineering.
Features
1. The equipment body can be designed into many modules to ensure
the long term and stable running;
2. Compact structure which can enlarge the heat exchanging area in
order to add the heat transfer area and less leakage
3. Improve the heat transfer efficiency
4. Structure arrangement: In line or staggered arrangement
Details
