    Product Description
     
    spiral finned tube is a kind of spiral groove with certain width and depth which is pre-processed on the steel tube, and then the steel strip is inlaid on the steel tube on the lathe.During the winding process, due to a certain pre-tightening force, the steel belt will be tightly squeezed in the spiral groove, thus ensuring a certain contact area between the steel belt and the steel tube.To prevent the strip from bouncing off, the ends of the strip are welded to the steel pipe.In order to be easy to insert, there should be a certain side gap between the steel belt and the spiral groove.If the side gap is too small to form interference, the Mosaic process is difficult to proceed smoothly.In addition, there is always some rebound of the wound steel belt, which results in the poor connection between the steel belt and the bottom surface of spiral groove.The inlaid fins can be carried out on general equipment with low cost and low efficiency.

    Advantage
     
     
    1. Excellent wear resistance
    The wear is mainly due to the impact and cutting effect of gray particles on the pipe. The wear is the most severe around the pipe at a level of 30 degrees. When S1/d=S2/d=2, the wear amount here is 3 times of the average value.
    Due to the change of air flow direction, the second row has the most severe wear. When S1/d=S2/d=2, the second row is twice as much as the first row wear, and the subsequent row wear is generally 30% to 40% higher than the first row.
    The arrangement of the first row is the same as the arrangement of the first row in the sequence.Under the same conditions, the maximum wear of the longitudinal tube bundle is 3-4 times less than that of the staggered tube bundle.
    The abrasion speed of the pipe is directly proportional to the non-uniformity coefficient of the flue gas velocity KV3.33, and is directly proportional to the non-uniformity coefficient of the fly ash concentration Ku.
    The h-shape finned tube economizer is arranged in sequence. The h-shaped fin divides the space into several small areas and has a uniform flow effect on the airflow. Compared with the optical tube economizer, spiral fin economizer and longitudinal fin economizer with staggered arrangement, the wear life is 3-4 times higher under other conditions.
    Flue gas side damper protects the bend part.
    2. 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.
    3. 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.
    4. Reduce smoke lateral resistance
    Reduce the operating and investment cost of induced fan.
    5. Reduce welding joint and improve reliability.
