Finned Tube----Square fin tube, H fin tube, rectangular fin tubes, double H fin tubes

H fin tube known as square fin tube, There are two type of H fin tubes, one type with single tube, normal called square fin tube, the other with Double tube, normal called rectangular fin tubes. and also manufactured as per customers requirements. Due to rectangular shapes, which can offer large surface area compared to the Spiral Finned tubes. Due to larger surface area available, these finned tubes are used mostly in Air Heating application to reduce the overall size of the equipment.

H fin tube 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.

Max. Working Temperature: 300 °C

Atmospheric Corrosion Resisitance: Acceptable

Mechanical Resistance: Good

Fin Material: Copper, Alloy Steel, Carbon Steel, Stainless steel

Base Tube materials: Any material available, such as Carbon steel Tube, A179, A192, A210, stainless tube A269/A213 T5 T11 T22 304 316


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.

Key Words: Finned Tube, Fin Tubes, Embedded Fin tubes, G type Finned tube, L Fin tube, "LL" type fin tubes, KL fin tubes, knurled finned tubes, Tubos Aletados

Product Description

Industial boiler part heat exchanger H finned tube economizer is a kind of boiler parts, to have two steel circular symmetry to be welded on fluorescent tubes to form ins positive shape much like letter "H", so called H-fin tube. H finned tube economizer widely used in utility boilers, industrial boilers, marine power, such as the tail of heat exchanger components.

 

Application of Boiler H Finned Tube Economizer

Industial boiler part heat exchanger H finned tube economizers are tube heat exchangers located in the top section of a boiler. They raise the feedwater temperature to slightly below saturation temperature. H finned tube economizers are so named because they can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency. H finned tube economizers preheat the cold water used to fill water wall panels.

 

Material Structure of Boiler H Finned Tube Economizer

Consists of a serious of H fin tubes, the headers of inlet and outlet, bend, frame and other auxiliaries.


Characteristics of Boiler H Finned Tube Economizer

1). Add the heat exchange area and reduce the number of tubes, also increase the fume flow section area to reduce the fume speed and abrasion.

2). H type fin tube can be made to double H type fin tube, high rigidness to fit long tube row.

3). H type fin economizer arranged in line to make the space into many small zones, averaged air flow to reduce the abrasion.

4). With straight channel to gain the best ash-blowing effect.

5). The compact structure to reduce the weight and reduce the manufacturing cost.

 

Quality Control:

1. Strength calculation report with applied materials information;

2. 100%NDT(non-destructive inspection) report of steel plate, tube and welding rod;

3. 100%X-ray inspection report (welding seam): to ensure the quality of the entire boiler;

4. Hydraulic test report: ensure the stand
