Square Fins are welded on 1 steel base tube. We call it H Fin Type Tubing. Square Fin Tube with 90 Degree Bends, Rectangular Finned Tubes with 90 Degree Bends
We offer rectangular finned tubes as single or twin tubes in addition to the proven helical or spiral fin design. These rectangular finned tubes are particularly well suited for dust-laden exhaust gases that tend to scale, e.g. for economizers in coal or oil-fired units. Straight tube arrangements favor a decrease in scaling as well as easier cleaning and maintenance and will lower the resistance coefficient.
We are designing and manufacturing fin tube modules, economizers/heat exchangers, and suitable heating surface cleaning systems according to your requirements.
HH Finned Tube with Bend
Rectangular Single or Twin Finned Tubes
H fin tube known square fin tube, there are two types of H fin tube, one type with single tube, normally called square fin tube, and the other with Double tube, normally called rectangular fin tube. and also manufactured as per customers' requirements. Due to rectangular shapes, which can offer large surface area compared to Spiral Finned tubes. Due to the larger surface area available, these finned tubes are used mostly in Air Heating applications to reduce the overall size of the equipment.
H Finned Tube
H fin tube is a kind of boiler part, which has two steel circular welded on base tubes to form fins positive shape much like the letter "H", so-called H-fin tube. H-economizer is widely used in utility boilers, industrial boilers, and marine power, such as the tail of heat exchanger components.
Principle:
H Finned Tube economizer has two rectangular fins, similar to a square, its edge length for the fluorescent tubes of 2-fold, and an expansion of the heating surface.
Rectangular Fins are welded on 2 steel base tubes. We call it HH or Doule H Fin Type Tubing.
HH Finned Tube economizer flash resistance welding processes used the welding seam after the high rate of fusion, weld tensile strength, and good thermal conductivity. H-economizer can also manufacture dual tube "double H" type fin tubes, its rigid structure, and can be applied to a longer tube row occasion.

Rectangular Finned Tubes
Single-pipe square-finned tubes and twin-pipe rectangular-finned tubes are also manufactured as per customers' requirements. These are particularly suitable for dust-laden exhaust gases, e.g. for economizers in coal and oil-fired units or waste incinerators.
