Double H Fin Tube ND Steel 38*4 bare tube ND Steel Fins 2 thickness 185 width GB standard

Product Description

1.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.

2.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.

ProductH-fin Tube
Base PipeWelded or Seamless
Materialcarbon steel, alloy steel, stainless steel, non-ferrous alloys and nickel alloys.
ApplicationH economizer,H evaporator,H superheater,H air heater and etc.


1.Our products can be modified according to our customers' needs and the situation.we design and manufacture safe,reliable and efficient H-fin tubes.

2.HD BOILER has also completed stand-alone product quality assurance systems.

3.Production of H-fin tubes are with high heat transfer efficiency, they have flue gas resistance and are designed for a small space.


1.Using an economizer does not just prevent heat loss — it can also extend the life of the boiler.

2.Stresses from using cooler temperature make-up water, known as “thermal shock”, can subject wear and tear on the boiler’s structural integrity over time.

3.This hammering “shock” effect occurs as the boiler’s fixed tube-sheets and fire-tubes rapidly contract from the sudden make-up of cooler temperature water.

4.However, when this water is pre-heated, the temperature differential is far less extreme, putting less strain on the boiler and giving it a longer operating life.


1. The equipment body can be designed into many modules to ensure the long term and stable running;

2. The low temperature economizer manufactured by our company can guarantee the wall temperature is 5-10 ℃ higher than the acid , and flue outlet temperature is 10-15 ℃ higher than the wall surface temperature

3. Wall surface temperature can be adjusted according to the boiler load and fuel changer to avoid corrosion under low temperature

4. Changer the DCS system of the existing boiler to achieve the auto and remote control by computer.
