ASTM H Boiler Fin Tube Heat Exchanger Steel For Steam

ASTM H Finned Boiler Fin Tube / Heat Exchanger Steel Tubes For Steam Boiler

Product Description

H fin tube Performance characteristics
1) The economizer uses H-type finned tube economizer instead of smooth tube economizer, which can increase the heat exchange area and reduce the number of tubes, so as to increase the flue gas flow section, reduce the flue gas velocity and reduce wear. Since the wear speed of the pipe is directly proportional to the 3.33rd power of the flue gas flow rate, if the flue gas speed is reduced from 9m / s to 7m / s, the wear speed will be reduced to 43% of the original. At the same time, the experiment shows that the finned tube itself can concentrate the fly ash to the middle of the tube row, so the structure of the finned tube economizer can reduce the wear
2) H-type finned tube can be made into double tube "double H" type finned tube. Its structure has good rigidity and can be applied to the occasion with long tube row.
3) The H-shaped finned tube economizer is arranged in line. The H-shaped fin divides the space into several small areas, which has a flow sharing effect on the air flow and greatly reduces the wear
4) H-shaped fins can achieve the best soot blowing effect due to the formation of straight channels on both sides.
5) The space is compact, the overall weight is greatly reduced, and the cost is reduced
6) Energy saving and low power consumption: the economizer used for the generator set can reduce at least two-thirds of the exhaust heat loss of the generator, and the power consumption per ton of steam is only 2 ~ 4kw
7) Simple operation and maintenance; Labor saving: the overall assembly of the economizer leaves the factory, with few moving parts, simple structure and easy installation. High automation level and simple operation and maintenance can reduce the number of operators.

Company information

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.

Structure

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.
