Stainless Steel Square Fin Tube

H/HH Type Fin Tube Product Description:

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.

H/HH Type Fin Tube(Square Steel Pipe) Manufacturing Process:

It adopts high frequency welding spiral technology with high frequency power supplies as the heat source to heat the steel strip, steel pipe at the same time,be welded together.

H/HH Type Fin Tube(Seamless Square Tubing) Advantages:

1) The H-type finned tube economizer instead of the smooth tube economizer can increase the heat exchange area, reduce the number of tubes, increase the flue gas flow section, reduce the flue gas velocity and wear.

2) The H-type finned tube can be made into a "double H" type finned tube with double tubes, which has good structural rigidity and can be used in the case of long tube banks.

3) The H-type finned tube economizer is arranged in sequence. The H-type finned tube divides the space into several small areas, which has the function of flow equalizing and greatly reduces the wear

4) The best soot blowing effect can be obtained by forming a straight channel on both sides of H-shaped fins.

5) The space is compact, the overall weight is greatly reduced, and the cost is reduced

6) Energy saving and low power consumption: the economizer used for the generator unit can reduce the heat loss of exhaust gas of the generator by at least two thirds, and only consume 2-4kw per ton of steam

7) Simple operation and maintenance; labor saving: the economizer is assembled as a whole, with fewer moving parts, simple structure and easy installation. High level of automation, simple operation and maintenance, can reduce the number of operators.
