Square Type H Fin Tube For Boiler

H/HH Type Fin Tube Product Description:

H Fin Tube is formed on both sides of the straight channel, can achieve good blowing effect. The space is compact, the

overall weight is reduced greatly, reduce cost; H type fin can flow space utilization effectively, keep the fin area and fin is larger than the thickness of the fin; can choose according to need any abrasion; fins are parallel to each other and independent, no effect of helix angle, which is convenient to ash."H" TYPE Finned tube can not only improve the windward side near the stagnation point speed,increase the axial purging,can increase the leeward surface reflux disturbance again.The velocity distribution characteristics make H finned tubes is not easy to dust.

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

Square or rectangular fins are welded on steel base tubes.

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.

H/HH Type Fin Tube(Square Galvanized Pipe) Properties:

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.

H/HH Type Fin Tube(Seamless Square Steel Tube) Applications：

Economizers, Boilers, Heat Exchangers. Often used in non-corrosive gas streams, minimal resistance to gas flow and the straight gas paths inhibit fouling and ease cleaning.
