1.carbon steel/SS material, 2. Single H or double H, 3.100,000meters per week, 4. Samples available - details see: https://www.machineto.com/double-h-finned-tube-for-power-plant-10247612

1.Name:

H fin tube, also know as H fin economizer, H fin tube economizer, H type finned tube, squire fin tube .

It is a kind of boiler parts, to have two steel circular symmetry to be welded on fluorescent tubes to form fins positive shape much like letter "H", so called H-fin tube.

2.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.

3.

H economizer flash resistance welding processes used, the welding seam after the highrate 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.

4.Performance characteristics:

(1) Excellent anti-wear performance

(2) Less fouling

(3) Compact space

(4) Welded Joints less

(5) Stability

5.Applying scope

Widely used in utility boilers, industrial boilers, marine power, such as the tail of heat exchanger components.
