H type fin tube for heat exchanger / seamless base tube |
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:
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.
H-economizer flash resistance welding processes used, the welding seam
after the high rate of fusion, weld tensile strength, and has 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.
Supplying Scope:
Fin tube Specification:Chinese GB standard or equivalent ASME standard
or others
Material: carbon steel, stainless steel, Aluminium and alloy steel;
