Description of H-fin boiler tubes
The heat transfer tube of the boiler adopts the H-shaped fin tubes, it is to weld two pieces of steel with arcs in the middle of the arc symmetrically onto the raw tube to form the fins (ribs), the front shape is quite like the letter “H”, so it is called H-finned tube.
The fins of the H-finned tube are rectangular, approximately square, with a length of about 2 times the diameter of the tube and an extended heating surface. H-finned tube can also be made into “double H” finned tube of double-tube, with good rigidity structure, it can be applied to the longer row of the tubes.
Advantages of H-finned tube:
1) Excellent wear resistance
(2) Fouling reduced
(3) Reduce the resistance of exhaust gas
(4) Fins and steel pipe welding fusion rate is high
(5) Compact structure, high heat efficiency
(6) Shock-proof and noise reduced
(7) Convenient for installation, operation and maintenance
