Alloy Steel T11 T12 T5 T22 Fin Tube, ASTM A213 ASME SA213 Boiler Pressure Fin Tube for Power Plant
Product Introduction
H fin tube is used to recover the gas waste heat of the power station boiler, the industrial boiler, the industrial kiln, the ship power plant and etc, and effectively improve the utilization rate of the fuel, and the heat exchange element is arranged at the tail of the system flue.
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.
Advantages of H-finned tube:
The H-finned tube is the main heat exchange component in the whole exhaust gas boiler, and the H finned tube has the following advantages.
(1) Excellent wear resistance
The H finned tube heat exchanger is arranged in line, and the H fins separate the space into several small areas, which have the effect of equalizing the air flow, comparing to the smooth tube heat exchanger with the staggered arrangement and the spiral finned heat exchanger And so on, in the same other conditions, the wear life is higher 3~4 times.
(2) Fouling reduced
The formation of fouling occurred in the dorsal side and windward side of the tube. The staggered arrangement of the tube is easy to flush the tube bundle, the fouling at back side is less. It has a good self-cleaning function at the appropriate wind speed. On both sides of the H finned tube are formed straight channel, soot, it can get the best soot effect while adopting soot blower.
(3) Reduce the resistance of exhaust gas
As the H fins form straight channels on both sides, and the spiral angel of the spiral fins steer the direction of the airflow, the fins are prone to fouling and have a greater flue resistance than the H fins. Therefore, the use of H-finned tube can reduce the wind resistance, reduce the fan operation and investment costs.

Carbon Steel Titanium Spiral Finned Tube Coil For Boiler Economizer ASME Standard
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.
Details
1.Our products can be modified according to our customers' needs and the situation.
