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.
