Double H Fin Tube ND Steel 38*4 bare tube ND Steel Fins 2 thickness
185 width GB standard
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
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
|Base Pipe||Welded or Seamless|
|Material||carbon steel, alloy steel, stainless steel, non-ferrous alloys and
|Application||H 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
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
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.
