H Type High Frequency Welding Boiler Fin Tube
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
