Product Description

Product Description
H-type finned tubes are divided into single H and double H types, and are widely used as heat exchange elements in the flue gas waste heat recovery system of power station boilers, industrial boilers, kilns, and ship power plants. So why is the H-shaped finned tube so widely used? Because of its unique structure, the structure is stable and not easy to deform, and the heat transfer efficiency is high! The H-shaped fin tube adopts a unique sawtooth structure. The fins are oppositely welded on the surface of the steel pipe. The welding part of the fin adopts multiple sawtooth shapes. The heating surface is uniformly welded and firmly. The surface of the welding angle is smooth. The fusion rate is as high as 98% and has a good heat transfer coefficient. At the same time, the H-shaped finned tubes are arranged in series. The fins divide the surface space of the steel pipe into several small areas, which have a flow equalizing effect on the flue gas. Compared with the staggered arrangement of smooth tubes or spiral fins, the H-shaped fins The sheet tube has good steel structure and is resistant to deformation, and has a longer wear life.

Features:

1. Welding speed The welding time for each pair is less than 3 seconds (not including loading and unloading time and annealing time)
2. Welding strength and stability 2.1 Pull-off force test: greater than 200mpa or partial tearing of the steel pipe 2.2 Weld width: greater than the thickness of the fin, that is, the welding rate>100% 2.3 Weld bending resistance test: The fin is bent at 20 degrees No crack 2.4 Hammer test: hit the upper part of the fin parallel to the steel pipe until the fin falls off and the fin itself must not break
3. Unit manufacturing capacity 3.1 The unit is equipped with fixtures suitable for double pipes and single pipes 3.2 Finned tube length 1m ~ 14m 3.3 Fin thickness 2mm ~ 3mm 3.4 Steel pipe size 19mm ~ 56mm 3.5 Weldable material range Base tube + Fin: Carbon Steel + Carbon Steel Carbon Steel + Low Alloy Steel (Manganese Steel) Alloy Steel + Alloy Steel Alloy Steel + Stainless Steel Stainless Steel + Stainless Steel
4. Product dimensional accuracy 4.1 Full length of fin segments-1mm ~ +1mm Segmental motion accuracy -0.5mm ~ +0.5mm 4.2 Piece pitch -0.5mm ~ +0.5mm 4.3 Fin and steel pipe perpendicularity -1 degree ~ +1 degree 4.4 The flatness of the same group of butt-welded fins is -0.5mm ~ +0.5mm except for the height difference caused by the thickness tolerance of the fin itself 4.5 The height difference of the same group of butt-welded fins -0.2mm ~ +0.2mm height caused by the dimensional tolerance of the fin itself Excluding the difference 4.6 Tolerance of double tube center distance -0.5mm ~ +0.5mm 4.7 In the same steel pipe material, the same length and number of fins, the length of different fin tubes after welding
