Aluminum , Stainless Steel Welding Finned Tubes For High Efficient Heat Transfer
Introduction of Product
Compared to the traditional fin tube or spiral tube,the H-fin tube can greatly expand the heating surface.H-fin Tubes have two steel discs,with fluorescent tubes symmetrically welded together to form fins(fins of butterfly piece)creating a shape that looks somewhat like the letter"H",creating an efficient energy saving, extension heating surface.

Features
1. Reduced dust accumulation
Ash formation occurs on the pipe's back and windward sides.It is easy to scour the pipe by disarrangement, and less dust accumulates on the back.As for the pipe arrangement in sequence, due to the fact that the air flow is not easy to flush the back of the pipe, there is more ash accumulation in the pipe arrangement in sequence than in the wrong column.
The h-type fin is welded on both sides of the pipe, which does not accumulate ash, while the air flow flows straight, the air flow direction does not change, and the fin does not accumulate ash.
A gap of 4-10 is left in the middle of the h-type fin, which can guide the air flow to sweep the pipe fin to accumulate dust.
As the spiral Angle of the fin guides the flow direction, the ash accumulation of the fin tube is more serious, and the economizer which does not form loose ash cannot be used.Field operation shows that the h-shaped fin tube does not accumulate ash, while the spiral fin is seriously.
The longitudinal fin tube is formed by the flow of air along the fin as the fin is welded on the surface and back of the accumulated ash.Some areas are prone to dust accumulation.
The h-shaped fin, which forms a straight channel on both sides, has the best blowing effect.
2. Compact space and low cost
The pipe set is much compact and reduces the height of tail smoke well.
The total weight is greatly reduced and the load of the suspension system is reduced.
Reduce cost of economizer and integral boiler.
