H fin tube, known as Square fin tube & H Finned economizer, finned tube, is used in boilers parts, marine power.
It is a kind of boiler parts, to have two steel circular symmetry to be welded on fluorescent tubes to form fins positive shap much like letter "H", so called H-fin tube. H-economizer widely used in utility boilers, industrial boilers, marine power, such as the tail of heat exchanger components.
Principle:
1.H-economizer two rectangular fin, similar to a square, its edge length for the fluorescent tubes of 2-fold, an expansion of the heating surface.
2.H-economizer flash resistance welding processes used, the welding seam after the high rate of fusion, weld tensile strength, and has good thermal conductivity. 3.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.
Supplying Scope:
Fin tube Specification:Chinese GB standard or equivalent ASME standard or others
Material: carbon steel, stainless steel, Aluminium and alloy steel;
Applying scope:
Widely used in utility boilers, industrial boilers, marine power, such as the tail of heat exchanger components.
